How Indoor Air Pollution is created?

Today's tightly-sealed indoor spaces trap all kinds of contaminants: chemicals and irritants released by cleaners, carpeting, paint and perfumes, and pollutants like tobacco smoke, pollen, mold, dust, and animal dander can cause asthmatic and allergic reactions. The solution is to remove these pollutants from your interior spaces. Part of that solution is a high performing HEPA air purifier. High-Efficiency Particulate Air or HEPA. To qualify as HEPA by US government standards, an air filter must remove 99.97% of all particles greater than 0.3 microns in size from the air that passes through the unit.  According to the EPA, health effects may be delayed in creating symptoms and show up only after long or repeated exposure to airborne allergens and pollutants that can cause allergies (and more serious health problems) to develop later in life.

Why we don't sell ozone generating air cleaners?  Ozone generators produce the gas ozone, which is an extremely potent oxidizer. Ozone is of three oxygen atoms and is the same molecule that makes up the "ozone layer" of our upper atmosphere. Stratospheric ozone is a good thing because it protects us from dangerous UV rays; however, ozone in the air we breathe can be harmful to your health. The U.S. Environmental Protection Agency (EPA) states that "relatively low amounts can cause chest pain, coughing, shortness of breath, and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections and scientific evidence shows that, at concentrations that do not exceed public health standards, ozone is considered ineffective in controlling indoor air pollution."

The American Lung Association states that "ozone is a potent lung irritant and exposure to elevated levels is a contributor to the exacerbation of lung disease; it is especially dangerous for persons with asthma and other chronic lung diseases, children, and the elderly."
Many of our competitors sell ozone generators and ionic air cleaners that also generate some ozone, but we think any level of ozone is dangerous and we will not offer any air purifier that generates ozone.

What about Ionic Air Cleaners?  Our research, along with the prevailing opinion of most testing facilities, has found that ionic air cleaners are ineffective beyond a three foot radius of the unit. Most testers place a "do not recommend" on all the ionic air cleaners they've tested.

Thank you for selecting Bestfilters.com. We are consistently the highest rated online retailer of water filters and air purifiers.Certainly there are cheap, inferior air purifier products that don't perform as well and will need to be replaced in a few years when they wear out, that are available at the Big Box stores. We don't carry any of those.
