Air Purifier Allergy Review



What's the best allergy relief air purifier ? Because that depends on the allergy, and the size of the room you are trying to clean, I'll try and customize an answer just for you. In this article I'll be breaking down the technology by allergy, and make some recommendations based on room size.

I'm sure by the end you'll have the best allergy relief air purifier for your needs, and your budget.

If You Have Pollen Allergies

There is a wide range of air purifiers that include a HEPA filter and a wide range of prices. The most important thing to be aware of is that there are 2 types of HEPA filters. The first is a true HEPA filter. To qualify as HEPA by US government standards, a HEPA filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 micron-sized particles. The second is a HEPA-type filter, which means any variety of folded cloth or paper can fit may be used. The HEPA-type filter will be lower in price and a lot less effective. The differences to watch for after that include:

1 - Most HEPA replacement filters are overpriced. This can cost you every 6-9 months after your initial purchase. (See the Comparison Chart via the left menu to check HEPA prices)

2 - HEPA filters can vary in size, but most fit the square footage they cover.

3 - Air Purifiers that have "pre-filters" in front of the HEPA can extend the life of the HEPA purifier - saving you money. They're usually washable, and a good idea for trapping hair and dust.

If You Have Dog Cat Allergies

If dogs or cats are your primary allergy then HEPA is again the 1st choice, because HEPA will grab and hold animal dander. Dander is actually where a protein that is found in the dead cells causes the allergic reaction, and not the hair itself.

Because of the pet hairs a pre-filter is especially valuable. It is washable and extends the HEPA life by gathering hairs and some of the dander.

Mold Allergies

The best allergy relief air purifier for those with allergies to mold is one of the following:

1 - Negative Ions - These are healthy molecules that will kill mold out in the room, and on walls. It is not only safe, it can have a beneficial effect on energy levels, sleep, and breathing problems.

2 - Ozone - While ozone is the most effective way to kill mold it also has a downside. Ozone molecules can irritate lung passageways if breathed in high doses.

3 - HEPA - While HEPA will capture mold spores and keep mold from spreading it will not kill mold in the room, on walls, or in the filter itself. Some companies will promote HEPA as good for mold, but it won't do a good job on mold for these reasons.

Small Room Allergy Relief - Under $150

The best allergy relief air purifier for small rooms (under 400 square feet) in my opinion is the little $99 Alive Air Mini which includes HEPA, Carbon, UV, Pre-filter, Negative Ion and electrostatic. the filters are affordable, it's quiet (I have used one 24/7 on my bedroom for years when I sleep) and has 2 washable filters in it.


Large Room Allergy Relief - $297

My Favorite Large room (Under 865 square feet) air purifier for allergy relief is the Alive Air Purifier which includes HEPA, Carbon, UV, Tio2, Pre-filter, Negative Ion and electrostatic. The HEPA filters are as low as $33 and will last between 3-6 months.
