Some have a bitumen backing which I found lower in offgassing than the vinyl.įLOR has a different type of offgassing chemical odor than typical carpet, and I definitely find it offgasses faster. Their regular carpet lines are made from nylon (polyamide), and most have a vinyl backing.

The Food and Drug Administration has set a limit of 0.05 parts per million of ozone for medical devices. A small percentage of air cleaners that claim a health benefit may be regulated by FDA as a medical device.
Under certain use conditions ion generators and other ozone generating air cleaners (see can produce levels of this lung irritant significantly above levels thought harmful to human health. There is no difference, despite some marketers' claims, between ozone in smog outdoors and ozone produced by these devices. While indirect ozone production is of concern, there is even greater concern with the direct, and purposeful introduction of a lung irritant into indoor air. Ozone, a lung irritant, is produced indirectly by ion generators and some other electronic air cleaners and directly by ozone generators. Although some have suggested that these devices provide a benefit by rectifying a hypothesized ion imbalance, no controlled studies have confirmed this effect. While ion generators may remove small particles (e.g., those in tobacco smoke) from the indoor air, they do not remove gases or odors, and may be relatively ineffective in removing large particles such as pollen and house dust allergens. In some cases these devices contain a collector to attract the charged particles back to the unit. Abrasion can result in these particles being resuspended into the air. Ion generators act by charging the particles in a room so that they are attracted to walls, floors, tabletops, draperies, occupants, etc. From: Indoor Air Pollution: An Introduction for Health Professionals
