Air Purifiers, Air Filters

Indoor Air Quality deals with the content of interior air that could affect health and comfort of building occupants. The Indoor Air Quality may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon and formaldehyde), allergens, or any mass or energy stressor that can induce health effects. Indoor air pollutants are associated with many health risks including asthma. Recent findings have demonstrated that indoor air is often more polluted than outdoor air (albeit with different pollutants) although this has not changed the common understanding of air pollution. In fact, indoor air is often a greater health hazard than the corresponding outdoor setting. Using ventilation to dilute contaminants, filtration, and source control are the primary methods for improving indoor air quality in most buildings.
Getting the Right Filter
Particulate filters are usually not designed to remove gases. The standard furnace filter is a low-efficiency particulate filter. Unfortunately, it does an extremely poor job of removing anything. It is only capable of capturing fairly large particles. More than one indoor pollution expert has said, with tongue in cheek, that they are good for handling rocks, baseballs and tennis shoes, but little else. Actually, their main purpose is to protect the furnace's fan motor. They aren't designed to protect the health of the occupants.

Medium-efficiency filters come in a variety of styles for commercial applications, but the pleated, accordion-like style is common in residences. While the standard furnace filter is only an inch thick, these may be up to six inches thick. In order to install the thicker ones in a furnace, some minor modifications to the ductwork are necessary. The reason for the extra thickness is because these types of filters have more air resistance. By making them thicker in a pleated shape, designers have given them more surface area, thus lowering their resistance to air flow. Too much resistance means that the furnace fan motor would have to work too hard, possibly resulting in a burned up motor.

Techniques for analyzing indoor air quality include collection of air samples, collection of samples on building surfaces and computer modeling of air flow inside buildings. The resulting samples can be analyzed for mold, bacteria, chemicals or other stressors. These investigations can lead to an understanding of the sources of the contaminants and ultimately to strategies for removing the unwanted elements from the air.
