Indoor air levels of many pollutants may be 2-5 times, and occasionally, more than 100 times higher than outdoor levels. Indoor air pollutants are of particular concern because most people spend as much as 90% of their time indoors. Common sources can include household cleaners, pesticides, building materials, and radon. E B WILLIAMS o er whole house air purifying systems to remove up to 99.7% of these pollutants. 

Electronic Air Cleaners 

EAC is a central air purifier that cleans the air throughout your entire home. Installed as part of your central heating and air conditioning system, the EAC uses a combination of electrostatic technology and traditional air filters to remove 98% of airborne particles as small as 0.1 micron. These are particles measuring 100 times smaller than the width of a human hair, including: 

Allergens such as pollen, dust, dust mites, mold, ragweed, and pet dander Airborne bacteria, viruses, and germs Smoke and other particle-based fumes.
