Indoor Air Quality Services in the Quad Cities area of Moline, Rock Island, Davenport and Bettendorf

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.

Take a look below to see some of the products and services that we recommend and install for improving the air quality in your home.

Air Purifiers

An air purifier acts like the sun, using ultraviolet (UV) rays to destroy certain contaminants associated with asthma, allergies and respiratory infections. As air passes through an ultraviolet light air purifier, short-wave ultraviolet light waves inactivate pollutants. The term “inactivate” refers to the breaking down of the pathogens’ Deoxyribonucleic Acid (DNA) or Ribonucleic Acid (RNA). This makes them unable to function or reproduce.

UV devices also improve the efficiency of your ventilation system by keeping it from getting clogged.  They improve airflow by reducing built-up contaminants, reduce energy costs by moving air more efficiently, cuts down on HVAC maintenance by keeping the system clean, and improves efficiency and comfort with faster heating and cooling.

Benefits of Air Purification:

  • Helps Remove Bacteria and Pathogens
  • Neutralizes Unpleasant Odors
  • Less Dust in Home
  • Eases Allergy Symptoms
  • Eliminates Harmful Chemicals

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.


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.


Humidifiers have many benefits as well during the cooler, dry months, like reducing the risk of catching the flu, making coughs more productive during illness, reducing snoring, keeping skin and hair moisturized, and reduce static electricity. More moist air also tends to feel warmer, which may reduce the need to heat the home as much and save on utility bills.
