Why Shop With Purifier Nation

Thanks for visiting Purifier Nation, the definitive source for information on why every home and workplace should have an air purifier. Of the over 100 brands of purifiers that are sold in the United States, we have decided to carry only the highest end of the market. These are the only air purifiers that have been tested and demonstrated to work effectively and reliably over a long duration. The entry-level air purifiers sold at big-box stores are virtually ineffective when compared with the models in our inventory.

How An Air Purifier Benefits Your Family

Most people spend upwards of 90% of all their time indoors. And it may surprise many to know that the air indoors may be and in fact usually is much more polluted than the air outdoors. People tend to think just of household dust when they think of indoor air pollution, but there are many more causes of indoor air pollution that are all around us all the time.  These problems not only aggravate allergy and asthma symptoms, but they can cause significant health problems with prolonged exposure, not just in the very young or senior citizens, but with everyone.

How To Buy An Air Purifier

We detail the mechanics of air purifiers such as how they work and what to look for in one in our air purifier buying guide. After countless hours of our own research, we have decided to only feature air purifiers that feature HEPA filtration. These true HEPA filters remove at least 99.97% of particulate matter in the air such as dust, pollen, dander, mold, and dust mites, and have been repeatedly demonstrated to be many times more effective than other types of air purifiers.

In addition to HEPA filtration, some of our models also have such features as UV lights and activated carbon filters for microbial and odor disinfection. We don't carry ionic air purifiers, which have been shown to be virtually ineffective. And we don't carry any purifiers that generate ozone. Ozone is used in some circumstances to disinfect odors but is very harmful to your health, and these ozone-generating purifiers have in fact recently been banned by the state of California.
