Indoor air pollution poses huge health risks. Unclean air contributes to a variety of health problems, such as allergies, respiratory problems, asthma, bacterial infections and viruses. Air cleaners are a great way to improve your indoor air quality. Ventilation helps air quality. However, for homes without excellent mechanical ventilation, it’s not always practical to open windows and doors while running air conditioning in hot Tucson weather.
Two types of air cleaners, electric purifiers and UV lights, are especially effective. To determine whether you need one or both of these types of cleaners inside your HVAC system, first look at what each ones does.
Electronic Air Cleaners
Electronic air cleaners, such as HEPA filters, trap charged airborne particles. They suck air through an ionization area, where particles in the air become charged. These particles then stick to flat collectors with an opposite charge. Good electronic air cleaners remove allergens such as dust, mold spores, pollen. The best ones also remove bacteria, chemical fumes and odors.
UV Light Systems
UV (ultraviolet) lights are commonly used to sterilize equipment in the food and medical industries. The lights affect the DNA of biological contaminants, making it impossible for them to reproduce. UV lights sit inside your HVAC ducts and kill biological contaminants that pass through them. For example, UV lights kill mold spores, viruses and germs. UV light systems do not remove larger particles from the air, such as dust.
