Guide To Aircleaner in the home

Indoor air pollutants are unwanted,sometimes harmful materials in the air. Indoor air pollution is among the top ﬁve environmental health risks. Usually the best way to address this risk is to control or eliminate the sources of pollutants, and to ventilate a home with clean outdoor air.
The ventilation method may, however, be limited byweather conditions or undesirable levels of contaminants contained in outdoor air. If these measures are insufﬁcient, an air cleaning device may be useful. Air cleaning devices are intended to remove pollutants from indoor air.
Some air cleaning devices are designed to be installed in the ductwork of a home’s central heating, ventilating, and air-conditioning (HVAC) system to clean the air in the whole house.
Portable room air cleaners can be used to clean the air in a single room or speciﬁc areas, but they are not intended for whole-house ﬁltration. The following pages will provide information on different types of air cleaning devices and how they work.
