Air filtration units capture airborne particles such as dust, pollen, bacteria, dander, spores, etc.. Some units are non-electric media and some have combined media and electric functionality, which perform even better. Performance is measured in terms of efficiency at trapping micron-sized particles. (A human hair is 100 microns in diameter.) Removing a higher percentage of contaminants from the air may reduce the incidence of associated illnesses and allergy symptoms.

Dry winter air in the home can cause dry skin, nose and throat discomfort and static electricity. It also can cause wood floors and trim in your home to shrink, walls to crack and wood instruments to warp. When a furnace runs in the winter it consistently dries the air. Replenish moisture levels in your home by installing a whole-house humidifier.

An ultraviolet purifier mounts on a home duct system and emits short-wave ultraviolet light into the ducts. This germicidal light kills a high percentage of micro-organisms in the air passing by it.

Benefits of dehumidifying your home include the following:

• Reduces humidity levels without cooling
• Better comfort control
• Improves indoor air quality by lowering the chance of mold, mildew, and bacteria
• In new construction homes a dehumidifier can reduce the size of ducts required
• Saves money by reducing the size of cooling equipment
