Allergic Asthma Need Advice On A Air Purifier

Hello all,

I wanted to ask for some advice. I am considering purchasing an but I have not found any information that shows they really work for allergies and asthma. I would love to hear from you on your own experiences, and any recommendations you can give to a newbie. I have been reading up on this forum and honestly, I am extremely confused. Please help and maybe we can all learn together. If someone has experience with purifiers from the review above (that's only one I found), and could provide any form of feedback, that would be useful!

Thank you,Ult1mat3X

    Welcome Ult1mat3X!    

    Here is a link to the AAFA web page with all the certified air purifiers listed. 

    I have two of these air purifiers to help with our home's indoor air quality so I can breathe better with my asthma.  One is in our kitchen and the other in the bedroom.  I can notice a distinct difference in how fresh and odor free the air is when the air purifiers are on.

    The two I have are - 

    and the 


    The DX55 is quieter than the DX5 but is also a larger machine.  Both are certified to "remove 99.97% of airborne particles as small as 0.3 microns" including  


    • 4-stage hospital-type filtration.
    • AeraSmart™ Sensor that monitors the air quality and automatically adjusts the fan speed to keep your air purified.
    • True HEPA filter with AeraSafe™ antimicrobial treatment that safely removes 99.97% of airborne particles as small as 0.3 microns, including pollen, ragweed and other allergens, viruses, germs, dust mites, mold spores, and cigarette smoke.
    • Extremely effective at removing influenza and cold viruses from indoor air (based on independent testing).
    • Carbon filter removes odors.
    • Aera+™ Mode for allergy and cold/flu seasons.
    • Ultra quiet operation.
    • Fan Speed Indicator that lets you manually adjust the fan speed setting – low, medium, or high.
    • Filter Change Indicators that let you know when it is time to replace your Carbon or True HEPA filter.
    • User-friendly capacitive touch display panel that effectively communicates machine performance."


    The filters are easy to change.  

    Hope this helps!  Please let us know how you are doing!

    I like my air purifier in my room right next to my bed. If I sleep with it off I wake up stuffier than if it is on. But it is no cureall– my ex thought itd clear dander but it didnt significantly clear it out– I have to be in a cat and dog-free home with my allergies. And if there was a smoker here, I doubt itd help much with that especially if it was smoking inside. But for dusts and pollens– along with following other avoidance strategies like washing weekly in hot water, showering right after outdoor activities– it helps to keep the air clean. 

    Things you have to remember: vacuum out the prefilter weekly (it gets full of the dust it traps). Buy new HEPA filters when the indicator light turns on. Make sure you get the right size for the room. 

    I use a germ guardian brand:

    I've got 2 Winix brand ones-just recently bought the second one and I love them both.  I was able to work in a construction zone (new building) with the paint, glue, plastics etc without any issues with my asthma.  I keep one at work now to handle the patients that come in with perfume on-clears that smell out right away and the other at home.  Like Shea said-you have to maintain them or they end up being just dust magnets themselves but they are definitely worth it.  Dh has allergies/sinuses and the one we recently purchased for home was mainly because of him.  He could tell a huge difference how he felt when he got up each morning that mine was in the bedroom running.
