Appliance Research: Choosing a Low Ion/Ozone Room Air Purifier

Air Filters and Purifiers for Urban Apartments:

Why use a no ozone or Ion air purifier? A fairly extensive U.S. Environmental Protection Agency report titled “Ozone Generators that are Sold as Air Cleaners” delves into the details of what Ozone is, how Ozone is harmful and  potential health effects of ozone.

In addition to the EPA, the California Environmental Protection Agency: Air Resources Board has recognized the potential harm ozone/ion based air purifiers and set up a certification process for indoor air cleaning devices. Two different classifications are used: Mechanical (which use physical filtration and do not generate ozone) and “Other” (devices that produce ozone concentrations of less than 0.050 parts per million)

I went with a reconditioned BlueAir 501R (refurbished) for high traffic areas and an AirFree Onix 3000 for the finished basement. For now, the table of “Finalists” is below:
