Air Purifiers for Asthma Patient

by Deepti

Hi Dwight,

My mother is an asthma patient. She lives in Mumbai, India and I wish to buy an air purifier for her. As per my research the HEPA air filter is the most recommended air purifier type for Asthma patients. You list a lot of air purifiers that use this type of air filter and I need help figuring out, which one would be best for my mother. I am looking forward to your recommendations. Shipping from the U.S. should not be a problem for me. Please help me make a decision.

Asthma Air Purifiers in India
by: Dwight

I am happy to hear that you are trying to get your mother some help with her asthma and other allergic reactions. I am also glad to hear that you will purchase products from the U.S. I recently gave some information to another person in India that couldn't afford the shipping costs and export fees, which are crazy expensive. I had to help them find something local and their was nothing I truly liked, but I tried to help the best I could. I also discovered that they lived near a dump that burnt trash weekly and was penetrating their home. I am hoping something like that is not happening near your mother's home.

Now about purchasing an air purifier for asthma. You are right about getting a True HEPA air filter that will stop 99.97% of particles down to 0.3 microns in size. If you read my website you will see that I suggest the IQAir HealthPro Plus and the Austin Air Healthmate 400 the most. They are both expensive. These both have the largest amounts of True HEPA (within the Austin Air Healthmate 400) and HyperHEPA (within the IQAir [99.97% of particles down to 0.03 microns]). As you can see the IQAir purifier has a better version of True HEPA and is truly the best.

After these it is almost a toss up between a couple different types. Many of these other types have half or less of the amounts of HEPA filter material and activated carbon. Air purifiers like the Alen A350, Whirlpool Whispure 510, BlueAir 601 and Honeywell 50250. Obviously, cheaper is not better, but the best are the best. Soon enough I will have some more video reviews and graphed testing charts to show all of this information.

Other Asthma Air Purifiers
by: Deepti

Thank you so much for your response. I did check out the reviews and yes it's really expensive. If it would have been one time cost I wouldn't have thought twice but the air purifier review said I need to replace air filters every 6 months, which would be expensive for me. The air cleaner review, which I went through actually compared Alive Air worth $299 and IQAir Pro Filter.

Also, the review suggested that the IQ filter covers 900sqft of area. Considering the layout of my house in Mumbai, the air purifier would be to big for my house. Are they available in small sizes? I came across some Do-it-Yourself videos which just places HEPA filters behind the table fan.

What would be your recommendation on Alive Air? Do you think buying an Alive Air and using a DIY HEPA filter would help?

Please let me know your thoughts. Appreciate your help.

Cheap Air Purifiers vs Quality Air Purifiers
by: Dwight

Hello Deepti,

It is funny that you mention the Alive Air purifier. It is actually a rebranded product that is known by a couple names like the "Multi-Tech XJ-3800 Intelli-Pro" (http://www.allegromedical.com/respiratory-therapy-c534/**multi-tech-intelli-pro-intelligent-air-purifier-p214909.html) and is currently being sold on Amazon as the "Surround Air XJ-3800 Intelli-Pro air purifier" (http://www.amazon.com/Surround-Air-XJ-3800-Intelli-Pro-Purifier/dp/B000HVTC5G). As you can see the prices for the exact same air purifier is around $200 instead of $299 as you saw. That company has a good marketer and is upselling the product as good because it has 9 stages of air filtration. It really just has 9 different technologies within it, which can be great. However, It is really hard to make all of those technologies work together in harmony. I still don't like the use of ionic air purifiers within the home, but the air purifier does work besides that fact. I haven't personally tested the air purifier, but I am going to because I am going to have to see just how these stages work because...... (they never open up the air purifier in their promotional videos to show you the filters or electronics.....why not?????).

As for your DIY suggestion about putting a fan in front of an air filter, believe that will not work very efficiently because a fan blows air in a ery wide angle and it is not blowing straight. That is why you need a ealed container to pull the into the air filter. However, that would be a ood test to show the faults of DIY and maybe I could come up with a etter design while testing.

The IQAir HealthPro Plus does come in a compact version (compact doesn't ave the V-5 cell). As for filter usage you should be able to get 3-5 years ut of the HYPERHEPA air filter, 2 years out of the V-5 cell and 6 months ut of the prefilter, which does a lot of the work for removing large and medium particles to make the HYPERHEPA air filter last long. These times are based on average use and not use 24/7, which would be about 1/2 to 1/3 that time. Yes it is expensive, but it works and is used by the U.S. government, medical and computer fields. It was even used on HGTV on one of the green home they gave away. I did give you a list of cheaper options, but it is up to you to decide what you need since you won't be able to truly have a one time fix. Every air purifier "filters air" and will need maintenance to some degree unless it is ionic air purifier that only needs to be cleaned, but I will not promote them for home use especially around people with respiratory issues, Fortunately, many of these multi-stage air purifiers allow you to turn the ozone generator on/off as you please.

Air filter in India
by: Ram

Hello Deepti,

If you are in a hurry to purchase an air purifier for your mother, you can look at Eureka air purifiers or Sharp air purifier models. I have both types and I am happy with them.

The reasons why I did not go with the ones available in U.S.:

1. Voltage difference
2. Availability of filters for replacement
3. Service
