Air Quality

Furnace Inspection

Purity, cleanliness and humidity are important to your lungs and to your home. Today’s homes are built much tighter. Airborne contaminants and particles can linger and recirculate dust and allergens throughout your home. We can now control air quality better than ever with the latest technology in air purifiers, air cleaners and humidifiers.

Air Purifiers

An air purifier acts like the sun, using UV rays to destroy certain contaminants associated with asthma, allergies and respiratory infections. 

Air Cleaners

You can improve your air quality by installing an air-cleaning device such as the iWave, which you can get directly from Doug’s. iWave uses patented needlepoint bipolar ionization technology to create positive and negative ions. When these ions are introduced into the air stream, they attach themselves to particles in the air. When the ions come in contact with pollutants, they become larger, so they are more easily captured by your ventilation system’s air filter.

Dust, smoke, odors, certain viruses and bacteria can all be suspended in the air you breathe, even when you don’t see them. Having an iWave installed will help clean the air in your living space. When air passes over the iWave Air Ionization System, ions produced by the device help reduce certain viruses, bacteria and other airborne particles, helping to create a cleaner environment.

DeHumidifiers

A dehumidifier is about much more than comfort, it is about keeping you and your family healthy. We love the Aprilaire dehumidifiers and we keep a stockpile of them because they sell like hotcakes when it gets warm outside. A portable dehumidifier is great for a storage room or as a temporary fix, but a whole-house dehumidifier like the Aprilaire is the way to go for a long-term solution to keep you comfortable and healthy.
