This webinar was recorded on on March 29, 2023

March is National Sleep Awareness Month and a time to discuss connection between allergies, asthma, and poor sleep quality. We spend about 90% of our time indoors, where the air is up to 5 times more polluted than outdoors, and a significant portion of that time is spent in the bedroom. According to a recent consumer survey from Blueair, an air purification expert, 65% of Americans stated they are woken up at least once a night due to breathing or respiratory issues such as allergies or asthma as a health factor directly impacted by air quality. Beyond the impact on allergies and asthma, sleep is critical to overall health life. The good news is steps can be taken to improve bedroom air quality.

Andrea: Thanks for joining us and we will wait a few more seconds and I know it takes a while for people’s computers to connect to the webinar so hold tight and we will be starting in 20 seconds or 30 seconds while we wait for people to load on. Thanks for joining us and we will be starting momentarily. Thanks for joining us and we are waiting a few seconds while people’s computers are connecting and the numbers are going up and we want to give a few seconds to everyone to make sure they can connect. Thanks for joining us. We are waiting a few more seconds while people connect and we will go ahead and get started so just hold on. Good afternoon and thank you for joining us today. We have a few housekeeping items. I am Andrea Jensen, the education specialist for Allergy & Asthma Network. All participants will be on buttes for the revenue and we will record today’s rep in our and posted on our website. — post it on our website. You can find all of our recorded repertoires at — webinars at We will take questions at the end of the webinar but you can put your questions in the Q&A tap at the bottom of your screen on the ribbon there at any time. We have someone monitoring the chat and if you have any questions or need help, we will get to as many questions as we can before we can conclude today’s webinar. We do not offer CEUs for this particular rep in our but we offer a certificate of attendance and some of you have noticed that we are doing a different webinar platform this year. You will receive a email a few days after the webinar and in that email that will come from Zoom, you will have a leak — link to download to get your attendance and a link to resources associated with this webinar and a link to the recording. We will try to add the link to the certificate or the certificate itself in the chat. We all know how technology goes so we will try to get that for you. Watch for and email — an email in a few days and you will be able to get that if it doesn’t happen. We will talk about National Sleep Awareness Month and the connection between allergies and asthma and poor sleep quality. Allergy & Asthma network is a grassroots organization that was started 35 years ago by a mom who knew other moms like her needed resources and support. Our mission is to end the needless death and suffering due to Allergy & Asthma and related conditions through advocacy and research. Today, it is my pleasure to introduce our speaker Odile Liu. Odile is the head of product marketing in Blueair. — 25 years of industry experience with a mission to provide clean air for the next generation and with over a decade of professional innovation design, development and marketing experience, she has led having a rare — array of global and emerging brands across various categories, leading strategic plan, business development, and more. She holds a bachelors degree from Georgia as the University and a Masters degree from Carson’s school of design and currently resides in New York City. Thank you for being with us as we discussed allergies and asthma and how they can impact sleep.

Andrea: — Odile: Thank you so much Andrea. Hope today’s — I hope today’s webinar will prove to be useful. Let me get going. A quick introduction on who we are and who Blueair is and what our brand does. A quick recap of that environment. Blueair is a company that was founded over 25 years ago where a fender when into bring the Swedish clean and natural air from the countryside endorsed for his children — and doors for his children. He has designed a proprietary H EPAsilent™ technology. What makes us different from other glands — brands because — we are proud of our Swedish heritage and a lot of our design and part of our DNA is to make design of the highest-quality quality and highest performing air purifier that is beautiful while using less energy to have a lesser impact on the environment. And one other factor that makes us different in this category is that we are very proud — we strive to be activists in the area when it comes to indoor air quality and since then, for the last one he five years, we have been fighting for children’s right to clean air and have delivered a number of improvements over a million children’s life — lives. We got the U.N. to acknowledge that clean air is a bundle rent — a fundamental right for children so bringing and/or quality and air quality in general high at public awareness has been our company’s mission. The general impact recap of where we are today. We had a very unusual two years as most of you have known with monumental changes to our life with disruptions with COVID and some of the biggest record-breaking wildfires in the U.S.. Since those last two years have stabilized or returned to normal, it is important to remember that even before all of these unique outliers in our life, there was always a large group of Allergy & Asthma sufferers that remain critically at need in our country so there are over 50 million Americans that have been diagnosed with different allergies and over half of them are suffering from seasonal allergy — allergic rhinitis. What people don’t recognize is the impact it has on the quality of life and what this means is over 3 million birthdays — workdays are missed first — per year and it is costing our economy over a billion dollars — $8 billion. Things have been stable over the last two years with heightened awareness around air quality and safety around indoor air. Today, what we will like to share is how indoor air quality can affect your sleep, given that this is the month for sleep and I want to teach and share a little data and insight. Firstly, why is and/or air quality so important? With all the education we have received with COVID, this is not so much a surprise but we do know now, especially with the EPA’s studies, indoor air can be up to five times more polluted than outdoor air and this is significant because as humans, we spend 90% of our time indoors and some of the most common household pollutants are PM 2.5, dust and pet dander and — and viruses and smoke particles, dust mites and cooking orders are different allergens and pollutants. They can trigger allergy symptoms. Because of the indoor space, there is a lack of ventilation, if you don’t have the proper intervention, these pollutants build up in your space because air is not static. It is moving. It builds up and leads to rotation so in the short term, people know that there are different air Tatian’s of the year, nose, and throat and some people who are sensitive get busy and have fatigues and headaches and those who have the quote conditions will have flareups with allergens — who have severe medical conditions will have flareups with allergens — allergies. Long-term, there is respiratory diseases and even cancer and the population most at risk of the very young and older adults and people with immune systems that are produced and people with cardiovascular or respiratory diseases are affected. With our dedication, we are looking for the next innovations on air purification solutions. We are looking and trying to understand how we can find solutions for our feet — for the American consumers and we can set — conducted a large-scale quantitative survey on Americans to understand their experiences around air quality and their home especially towards the end of the COVID era. Some families are pretty incredible and pretty impactful. Firstly, air quality has — is perceived as something that impacts the general health of the population. Of the thousand Americans we have surveyed, over 97% of them believe air quality in their home truly impacts their health, both — both physically and mentally. This is higher than what we have seen in years before COVID so this is something — I think part of the reason is heightened awareness with some of the most recent external events happening. When we asked them, how is air quality and pricing them, the majority of them are saying it is different respiratory conditions like coughing, wheezing, and a large percent, over 60% wrist — of respondents say they believe or feel the air quality has impacted their school — sleep quality. This is something that is higher than what we have normally seen before and more people are connecting the dots that some of their sleep quality issues are coming in stemming from air quality — and stemming from air quality. When we asked them what is the percentage of their household members that are suffering from some of these symptoms, over 81% of Americans have said someone in their household or a member of their household has suffered from air quality — poor air quality and most commonly, some of the common symptoms are allergic reactions, nasal congestion, coughing or wheezing headaches — wheezing, headaches, and poor night sleep — poor night’s sleep in a big percentage of Americans being affected by these conditions. When we ask whether or not people believe air quality is impacting their sleep, the majority strongly believe that air quality is something to do with their sleep quality — quality has something to do with their sleep quality. This is probably the most disheartening data we have seen, but 65% of Americans are woken up at least once during the night due to different respiratory issues like an allergic reaction or an asthma system –symptom. This is significant, especially if you look at people getting — woken up more than once, that is disheartening to see Americans are suffering. What we have asked is now that more Americans are connecting the dots that air quality is being impacted — is impacting their sleep, what are the actions and interventions they are taking and what it was pretty significant and interesting to us is that turning off and using the air purifier is one of the top three behavior changes are actions and interventions Americans are seeking to improve sleep. Not surprising, some of the most asked — at risk group for poor air quality our children and if you are someone, like a parent, like me, you know your child is costly congestion — congested and it was surprising to see the survey that Americans said air providers as the number one decision they make to improve their child’s sleep. Being validated through the survey results that pure — poor air quality and Allergy & Asthma symptoms are affecting the quality of life and part of this webinar is explaining how you can help. How do we achieve allergy relief with better sleep with an air per fire — air purifier? What exactly is air purification? Air is not a static material. It is constantly moving and infiltrating our home through different cracks, through and door gaps and — through window gaps and door graphs and air is constantly infiltrated with pollutants. An air purifier is equipment that removes contaminants to improve air quality. It is super simple. It almost is like a fan and what it does is that it has inlets that sucks in air and it pushes the dirt through a motor with a filter. It captures the pollutants and pushes out clean air. It is exactly how the fan works but you have the middle part that is a filter media that pushes out the best removes — that removes the food since. — the pollutants. Because the most common indoor air pollutant like dust and mold spores and smoke particles and viruses and bacteria are often the allergens often triggers allergic reactions and asthmatic symptoms sold in order to improve your symptoms and your overall sleep, by having the air purifier removing the allergens in your environment is one of the way to — ways to improve intervention of these symptoms. Because air is costly moving and coming through the different nooks and crannies of your home, the best way to always ensure clean air in the space is to leave the air purifier on 24/7 so it is cleaning the air at all times and another fact is the air purifier can only work at its optimal performance when you are cleaning or replacing the filter media regularly because that is the only way that allows the device to remain effective. As the filter adds more pollutants, there will be more clogging so without cleaning it out you will reduce the airflow of the cleaning area fire and the performance will drop. If you ever had a vacuum cleaner with the filter media in it and clean it, you will notice how dirtiest and that is the same thing with the air purifier. I will talk about understanding how to evaluate air purifiers and their performance. In the U.S. market, there is no —


That as purifier manufacturers how to communicate the performance and it is a minefield and he gets confusing for consumers and consumers are starting to understand and looking at other markets where they have regulated standards on how to evaluate an air purifier and one of the industry standards as the clean air delivery rate which is abbreviated as CADR. CADR is the objective and unbiased measurement on how well an air purifier is performing so the higher the CADR, it means there is a higher airflow and better performance and CADR is broken down by looking at two main parts of — that delivers your air cleaning performance and the first thing is the air filtration efficiency. When the derrière passes through the filter, how much pollutant is the filter removing? At accounts for an important part, airflow. Why is it important? A device can only clean the air in the room if it has the power to suck in as much dirt he air as possible and push out as much clean air as possible and moving high volumes of air through the air purifier is only way to reduce pollution. Additionally, sometimes, you also see a removal rate. A removal rate is different from filtration efficiency because it is about removing the pollutants — percentage of pollutants removed in Pierre in the room after a certain amount of time. — in the air in the room after a seven around the time — a certain amount of time. CADR and removal rates are factored realistically and reflect how air is in a consumer’s home and a CADR — higher CADR means a higher removal rate. You are removing more air at a time more frequently and removing pollutants. Why is airflow important? Our air is constantly being bombarded with pollutants so it is important the air exchange the air purifier can drive his frequent enough so it can constantly clean and maintain air. Therefore is an important metric that we feel — believe as part of the air purifier’s performance and that is why CADR is the better metric to evaluate air purifiers. When it comes to room size, this is an area that is confusing or could be misleading for any shopper looking for a air purifier. Room size is not a good value because it is dependent on relation to the air exchange, ACH. Air exchange per hours is how much volume of air or cleaning within this direction of time and based on that, if you can catch a late it within a suitable room size. It is important to know what is the room size the air purifier is capable of cleaning in relation to how frequently it is also cleaning the air. That is why a clean — room size can vary across the market and just because the air purifier is claiming a higher room size, it doesn’t mean it is better performing, it is just telling you it is clearing — cleaning a larger room size but it is only exchanging the room air once per hour. We recommend room sizes at the 4.8 ACH which means it takes 12.5 minutes to clean the air because the frequency of air cleaning —


Pierre and the room can remain free from pollutants and based on that, you can see things very. I will talk about the third party verification progress — 4.8 ACH is the ideal number. When the air purifier is recommendation — commending the size per the room, that is what is recommended. These are technical and it gets confusing so what are some of the easy tips that you can recommend to a patient to look for when they are choosing an air purifier? First and foremost, because performance is so important to alleviate the symptoms, for your patient, one of the recommended program and one program we participate in is the AHAM verified program. It is one of the largest associations in the U.S. and it has established an developed with all the expertise, a standard testing protocol — but call on how air purifier should test against and that is how people are using a way to test air purifiers and claim performance so manufacturers are dashed up air purifiers that participate in this program will send the devices to a third-party lab to be tested and based on those results, make a claim on how they perform and they will send to AHAM for verification and get the seal of approval with the performance so the easy way is to see whether or not any air purifiers have this AHAM Verifide logo. It recommends the room size based on the 4.8 air exchange and because the optimal way to ensure your performance is to leave it on at all time, it is according to consider air — energy C — energy efficiency. Energy Star is a great way to look at air purifiers. The EPA energy Star program has started including air purifiers as part of the most efficient program because they understand more and more Americans are using air purifiers and often time, you have more than one air purifier so they have a stringent standard to see that air purifiers that meet the standard will qualify in the most official program’s — program, which assemblers — which is similar to dishwashers. In California, we have to meet — stricter than the California resource board and participate in the zero ozone verification. If you’re looking to recommend an air purifier to a patient, especially to improve their sleep, then noise level is important to consider. Noise is a complicated medium and it can be a subjective experience so even though decibel levels are the most commonly marketed spec, it is not all encompassing and that is why more and more bodies like Quiet Mark have emerged to work with companies to prioritize noise reduction and what this organization does is, they evaluate home appliances and products, looking at the full quality of the sound. The test of the — the testing is not only looking at decibel levels but the tonality and frequency and pitches of our clients — of an appliances noise. You may hear a humming noise from your TV or dishwasher, those are different factors of the ways that don’t get reflected in the decibel level. That is why having a third-party certification on the holistic experience of noise can be helpful. Any product that is Quiet Mark certified is helpful to look at. Hopefully, we will see more of these certification bodies in the U.S. A quick summary of how to help your patient. — patient select your air purifier. Our recommendation is always look at the clean air delivery rate and look at the high clean air delivery rate. The higher number means the faster it will be able to clean the air and especially when it comes to asthma and allergy sufferers, that is something good for them to look for and secondly, when they are deciding on what size of an air purifiers should I look for, it depends on the room. When you are looking at the will room — the room coverage, you need to be sure and be sure whether or not the manufacturer is telling them how often is the ACH. Just by providing the room size is not enough to speak about the performance. You want to know how class — how fast it can clean the room so ACH is important. For you to educate your patient to look at. A small air purifier will take a longer time to clean the air on a larger room and what you can do for those who are really sensitive, you can recommend them having a product that is recommended for higher room size with higher ACH because it means it is cleaning fast. It will help relieve them of the discomfort and lastly, you want the performance and you want the fast clean and air exchange but it may be good, especially for those two looking — those who are looking to improve sleep, looking for new function national — functionalities like night modes. More air prayer fires have functionalities to dim the links — more air purifiers have functionalities to dim the lights. That is something to look for and hopefully they won’t mind it having it close to their bedroom and humming along. These are other factors. The final tips, beyond air purifiers on how to approve air quality. If you are suffering from different allergy symptoms, you may want to first identify and eliminate the pollutant source. It could be there is excess moisture in the environment, causing mold and looking at different elements and sources is one of the first steps and if you are in a area, of high traffic area that — or an area that suffers from wildfires, — look at your HVAC cracks to make sure you don’t give opportunities for pollutants to enter the space and you want to look at different ways to improve ventilation of the airflow in your home. For those that are hypersensitive, it is always good to invest in a smart air quality monitor device or smart device that can basically monitor the air quality and — inside and outside your home. If the outside palm index is in creating, they can proactively and preventively set strategies in the home and protect themselves. And we always recommend looking to invest in the high quality air purifier with the appropriate HEPAsilent™ –CADR space that you want. You will see air purifiers offering the auto mode and that means the air purifier has a sensor that can collect — detect the air quality of your home. We always — you should always remind your patient to directly change the filter because as the filter clogs up, it can bring in more air pollutants into your Eric and change the filter in your air purifier to ensure optimal performance so most manufacturers have a recommended replacement cycle. If you live in a highfalutin area or have pets, you want to consider or advise them to change filters frequently to ensure there is no lag in the performance. That is it for today’s webinar and thank you for having me. I am open for questions.

Andrea: Thank you. Wonderful information and I think these are one of the things people underestimate, indoor air quality. People worry about outdoor air quality with diesel exhaust and wildfires but people don’t realize how polluted are in air — indoor air quality can be so thank you for bringing that up. For those of you who have joined us a few minutes late, there are 50 million Americans that have allergies. I am with you, if any of you are out there is sniffling and wheezing, I am with you. We are talking about spring allergies and for those of you who are suffering, it is trees. We don’t get much of a rake and sometimes in summer, for those of you who are allergic to grass pollen, that can add more to your life and in the fall, you have ragweed and thistle. It — giving the air quality — keeping the indoor air quality as clean as you can is important. Thank you for that. In the check, people were talking about air purifiers and the local health department gives air purifiers to people in asthma programs. Odile Liu, do you have any information or have you cleverly — collaborated with any programs?

Odile: We have collaborated over the years with different organizations. Most recently, we are working and in touch with a department of Utah. — Department in Utah. — Department of health in Utah. Because indoor air quality has received heightened awareness, we have heard different education institutions like researchers looking to do research on adding air purifiers to the indoor home so we are always open to partner with different research groups. The gas burning stove top was top of the headlines a few weeks ago and I know in UC Berkeley, they are looking to do a study on that.

Odile: — Andrea: Once again, an example of something else that can cause problems with air quality people are sensitive to that particular problem. This might be something for those you on the line, check with your local health departments and see if they have a asthma home visit program and see if this is something they can help you with. I know — another option is, some of you may know about the green health — health and happy homes. They address the indoor air quality and they work with some asthma programs and they are able to provide the air purifiers as well as HEPA vacuums so some of you listening today and need help with students, I know we have school nurses on the line, check with your health department. That may be something in your area that you can tap in to. We have a question and as, can you address the efficiency of carbon filters for VOC?

Odile: VOC can be observed with carbon material but have a filter’s carbon is designed, it differs. Looking at the carbon weight is different. It is looking at the carbon materia — material your manufacturer is selecting. Carbon is known as a material can observe — absorb VOC affectively but that depends on the manufacturers design decisions.

Odile: Thank you for — Andrea: A for explaining that. We have another question in the chat. This is from Sondra. I have seen so many kids with asthma that her elementary age. Does that EPA work to train school engineers to design healthier busy — buildings and supplies school districts with electric school buses?

Odile: I can’t speak for the EPA specifically and their guidelines. I do know that we had work and have worked closely with different school boards during the COVID period. School boards were looking to we open and one of the requirements was — or school reopening was to add air purifiers into the classroom but evaluating the right purifier for education settings was complicated because noise levels impact the ability to learn. We talked to the Harvard public health at school — health school to look at different requirements but in terms of the EPA recommendation, I am not sure how much they are and vesting or investigating — and vesting or investigating — and vesting –investing or investigating.

Andrea: The EPA does have an indoor air quality tools for schools action kit. There is an app for that and there is help for school nurses and the second part of that, electric school buses. One thing that some of you on the line may want to check is that we are in the Department of environmental quality. Your DEQ at your state level, all states are different and I am in Utah. I know that one thing they have done is I believe, with the Volkswagen settlement, they use that money to get electric buses in Utah and they have done it by school district. Utah has used COVID funding from the federal government to provide purifiers for classrooms. For those of you on the line, check with your after Cartman’s — with your health departments. See if there is someone who can help you. What about have — air filters that include UV light’s –l ights?

Odile: This emerged during the COVID with the lot — with a lot of fear. UBC light is dangerous if exposed to the eyes and skin so the only way to ensure it can work in a air purifier setting is that it has to be designed to be properly enclosed within the air purifiers of the user doesn’t get exposed to it. That caveat is, from all the studies that –from UBC –UVC light is that in order for the light to kill bacteria’s and germs, the bacteria has to be exposed to the light for at least 10-15 sections. — seconds. When air purifiers are sucking in bed 30 air and pushing it through the device, that circulation is happening really fast so when that is happening, you may not actually have the bike — bacteria and viruses exposed to the UVC light to kill it or deactivate it so it is not super clear to us whether or not UVC air purifiers really work in the context when it is functioning as in the real-life settings.

Andrea: I am glad you know the science behind it. I am on the public health end. One of the things we had in the chat was, someone was asking about — let me go right back up. Many school buses are not air-conditioned. The children don’t have access to inhalers on the bus and please advocate your states to have clean tracks — truck and buses. Here at Allergy & Asthma Network , in May, we sponsor Allergy & Asthma day on Capitol Hill and that his own world asthma day and this year it is at May 3. You can attend virtually and meet with your representatives and talk with these issues — talk about these issues. These representatives are fabulous but they don’t know the background and information on every area with their constituents so let your voice be no and this is a free event and if you have time to put that link in their –there, you can attend in person or virtually. You can let your representative know about issues that are important. Thank you for that comment. We have –oh, one thing we were talking about in one of the chats earlier was, one of the most important things is, when we are talking about indoor air quality, it is important not to cover-up the poor air quality. When you walk into a room and it smells dusty, this was a problem in the beginning of COVID when I worked at a health department and they had a father –fogger and were spraying the entire building with disinfectant and asthma — as some with asthma, that is asthma trigger. Make sure you are improving the air quality and improving and Claire — purifying it. Odile, can you speak to that?

Odile: The best way to improve air quality is to remove things from the air, not adding anything. If you are spraying things to cosmetically mask a smell, it could backfire.

Andrea: Yes someone in the chat that posted — thank you and we have someone in the chat that posted that they have a purifier pilot in Roxbury, Boston. Oh Dale — Odile, we can coordinate you with that. It is helpful to know what is going on and behind the scenes.

Odile: Yes, we are always eager to connect with research experts.

Andrea: Let me scan and see if we have other questions for you. We have a long chat.

Sorry about that. Someone is talking about cockroach droppings that can cause problems. Absolutely. That is something we want to watch for in addition to all sorts of things schools use that have the little waxed candles that melt in different things like that to make candle — Russian smoke good — that can make classrooms smell good. Another question I wanted to ask you about and you talk about the importance of making sure to have an air purifier and you are not just looking for the decibel but also things that can make noise as well. I was texting my adult son that has an apartment and live somewhere else and he says there is a high-pitched down that comes from his air purifier. I am a little older and sometimes we are — when we are older, we can hear the sounds but did you notice that is something at Blueair that you tried to search for?

Odile: Yes and when you say we are dedicated to finding the best air purification solution, the performance, the cleaning performance and the speed of cleaning is the priority but a well-rounded and high quality product is looking at all the different factors that can impact an owner when they buy a home. We work hard to design products to reduce the noise level even at the highest vent speed. I can’t speak to the details of the engineering because that is where our our NT — R&D team’s brilliance comes into play but we design adding motors and looking at shields and over a quarter of air purifiers like to leave their air purifiers on the auto mode. If it detects the pollution level creeping up, it will adjust the spent — fan speed but if you don’t design the sound level to smoothly transition, what can happen is an abrupt change in the noise level that can lead to high-frequency or a pitching sound and that is deserving. — disturbing. You may have clear air you may have an intrusion for the noise so the degradation — the Gratian — degration — degration of the speed — if you look at Best Buy, they carry air purifiers and you can ask questions there and see the product in person.

Odile: — Andrea: the thinking. — good thinking. Thank you for that suggestion. You talked about that be air purifiers are not deserving — disturbing sleep and poor sleep, especially for school nurses, know-how that can affect students and dots — we know-how that can have affect — effect students and adults. Anything more you wanted to talk about how — about four sleep can correlate to problems in schools and work and general life — how poor sleep can correlate to problems in schools and work and general life?

Odile: Sleep itself as a part of quality of life is becoming more talked about in the public mindset and you hear about different sleep aid products from everything from supplements to wake up lights to white noise missing — machines. People are understanding how poor sleep can impact life and the quality of life but one of the most immediate things, because the majority of people that are suffering from sleep is stemming from Allergy & Asthma conditions. Talking more, being mindful and aware that air quality is something that you don’t see with your eyes is something you can trigger with poor sleep. Hopefully you can take this from this webinar.

Andrea: I am glad you brought this up because as a certified asthma educator, I used to run a asthma program. I know opening the windows to my bedroom, the pollen come in — will come in. Being careful about your air quality and keeping things out when you can and purifying the air that is there. All of that will cause disruption in our sleep. I feel like I cut you off. Was there something you wanted to say?

Odile: No. There are affordable air quality monitoring devices that you can find online and it could be something to add to your remote — more air purifiers have a sensor built in to the air purifier but what the range of pollutants a sensor can detect may vary. Some of the more advanced ones can detect fine particles to larger particle sizes like pollen. You may want to have a separate air quality monitor at the home and download a app — an app that contract a wide quality — variety of indexes in the external environment and that helps you take approaches to set up air purifiers or close up windows.

Andrea: That is a great idea and I know there are apps and different websites where you can check the pollen count as well as those in — as ozone levels. Was anything he wanted to add before we close — you wanted to add before we close?

Odile: No, thank you for your questions and I hope you found the webinar useful and hopefully, you will be able to learn to — learn something new in — with air purifiers and air purification and spread the word.

Andrea: Thank you. This has been very informative. As long as I have been around working with homes and for those of you who are on the line, we will have a survey that happens afterwards and I know people get tired of surveys and I look at each and every comment that you put in there and that helps me guide me — what I do with webinars. If you have suggestions, put them there and I do look at them and Odile, if you move one more slide, if it is being cranky, and go one more. We will be having — there you go.

We will have a webinar next week and this is a major shift in climate cycles and how it can be of benefit to Allergy & Asthma suffers in the U.S. Feel free to sign up for that and we will see you next month. Thank you, Odile, for everything. This is Andrea Jensen from the Allergy & Asthma Network and join his everyday as we breathe better together — and join us every day as we breathe but the together — as we breathe better together. Thank you, everyone.
