EnviroSept Electronic Air Cleaners: Indoor Air Quality

If you are typical, you spend 90% of your life indoors - at home, in the work place, shopping, etc. Energy conservation concerns over the last 20 years have led to tighter, better-insulated, climate controlled indoor environments. With these more energy efficient structures have come the perception that the indoor environment is healthier because polluted outside air is sealed out. Wrong! According to the EPA, whether you live or work in a smog-choked urban environment or enjoy the open spaces of rural living, indoor air has been found to be up to 70 times more polluted than the air outside.

Many of these air borne particles come from man-made materials used in furniture and upholstery, draperies, bedding, carpets, clothing paints, and cleaners. They also come from cooking, smoking, pets, candles, and fireplaces. Even some houseplants can produce pollutants.

There are approximately 20 million particles in every cubic meter of air and all are a barrier to a truly healthy and clean environment. These small particles pass through most filters and remain airborne or settle onto surfaces. The problem is removing these particles from the environment.

The following charts reflect the relative size of common airborne contaminants and their settling rate out of the air. Please note that most filters used in the home today only take out 90% or more of the particles greater than 10 microns. Below 10 microns, the results are minimal.
