Indoor air pollutants are unwanted, and sometimes harmful it is among the top five environmental health risks.
The best way to address this risk is to control or eliminate the impurities. As well as ventilate a home with clean filtered outdoor air. This is also known as IAQ or indoor air Quality.
The ventilation method may however be limited by weather 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 such as electronic air filters are intended to remove pollutants from indoor air.
Effective air cleaning devices are designed to be installed in the ductwork of a home’s HVAC system. High-efficiency air filters are used to clean the air in the whole house. UV lights are also used to kill harmful molds and bacteria.
Pollutants that can affect air quality in a home fall into the following categories.
Particulate matter – includes dust, smoke, pollen, animal dander, tobacco smoke, and particles generated from combustion appliances such as cooking stoves. In addition to particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses.
Gaseous pollutants come from combustion processes. Sources include gas cooking stoves, vehicle exhaust, and tobacco smoke. They also come from building materials, furnishings, and the use of products such as adhesives, paints, varnishes, cleaning products, and pesticides.
Another major factor others forget when it comes to air quality is the ductwork, like many other things in your home if the ductwork is outdated and torn, the fiber glass breaks down and becomes airborne in your home and harmful to breathe. Duct work has a maximum life expectancy of 20-25 years, however, it is recommended to be replaced after 15 years.
