Ionizer: U.S. Environmental Protection Agency

"Another factor with respect to ion generators, particularly those that do not trap some of the charged particles, is the effect of particle charging on deposition in the respiratory tract. Experiments have shown a linear increase in particle deposition with charge; therefore, the use of ion generators may not reduce the dose of particles to the lung."
(EPA Publication "Residential Air Cleaning Devices: A Summary of Available Information")

In a nushell: Ionizers can cause more inhaled particles to get stuck in our lungs. Charged particles can also soil room surfaces. In addition, particles that collect on room surfaces can again become airborne. Air Purifier 1 recommends you stay away from any cleaning device which produces charged particles, it is a potential health concern. This is especially important if you suffer from allergies or asthma. Charged particles and ozone, created by "Ionizers" or electronic air cleaners, are two byproducts you should avoid for your health's sake. This is according to the US Environmental Protection Agency (EPA) and the American Lung Association (ALA). Ionization creates charged particles which stick to our lungs easier. It is also a scientific fact that at concentration at which ozone is not harmful, it is also not capable of breaking down gas molecules.

The EPA states, "...ozone is generally ineffective in controlling indoor air pollution" and "Operation of these devices in the presence of Volatile Organic Compunds (VOC's) results in a soup of particles and gases".

The ALA states, "Because of the documented negative health impact of ozone, especially for persons with asthma, and the lack of evidence for its ability, at low concentrations, to effectively 'clean' the air, the American Lung Association suggests that ozone generators not be used".

IQAir systems never produce charged particles!

If the Air Isn't Moving, You Aren't Effectively Cleaning It!

Why Air Purifier 1 agrees with this principle:
We believe that air delivery is one of the most important aspects of air cleaning. Most other manufacturers overstate air delivery, some state the air delivery without all of the filters, and generally the consumer loses because the air isn't being filtered as needed. IQAir tests and certifies the air delivery of each individual air cleaner before they leave the factory. You will get a hand-written certification with your IQAir system showing the "cfm" it tested for each fan speed. "CFM" is a way of calculating air flow and it represents "cubic-feet per minute". Many other air cleaners suffer from a rapid reduction in air delivery due to insufficient pre-filtration. IQAir, on the otherhand, uses highly efficient pre-filtration to protect the HEPA filter from premature clogging.

The US Environmental Protection Agency states:
"The effectiveness of air cleaners in removing pollutants from the air depends on both the efficiency of the device itself...and the amount of air handled by the device." "The CADR (clean air delivery rate) is the product of the unit efficiency and the air flow rate, and is a measure of the number of cfm of air it cleans of a specific material".

In Sum:
Fanless/filterless systems such as ionizers which move between 20-30 cfm of air are far less effective than IQAir systems which have air delivery rates in the 260 cfm range. IQAir systems are designed to filter the air in a given room several times per day. IQAir systems also never produce any charged particles or ozone as 'Ionizers' do.
