Allergens, pet dander, dust, and mold can be a big issue for a lot of people and there are products on the market to help stop them. Germicidal UV lights kill allergens with the power of the sun, before they become an issue for you. Coil cleaning UV lights kill the germs and bacteria which build up on your indoor coil and cause odors and clogging of drain lines, which can cause costly damage to your home.
-Air filtration (also indoor air quality)
A normal one inch pleated air filter can only remove 60-80% of particulate matter from your home. Upgrading to a 4-5 inch high- efficiency air filter can bring that up to 80-90% without sacrificing critical air flow and they can last anywhere from 6 months to a year depending on conditions.
A whole home electronic air cleaner can clean up 99.7% of particulates out of the air by combining a high efficiency air filter with electrostatic air cleaning all in one. With an average replacement of the filter portion of only once a year.
