One Way to Improve Indoor Air Quality: Mechanized Air Cleaning Devices

Since most Americans spend the majority of their time indoors, good indoor air quality is increasingly more important for overall health. The air in your home or office can be a soup of chemicals, pollens, particles, and microbiological agents.

There are three major approaches to improving indoor air quality as enumerated by the EPA (United States Environmental Protection Agency).

The EPA states:

“Solutions to air quality problems in apartments, as in homes and offices, involve such actions as: eliminating or controlling the sources of pollution, increasing ventilation, and installing air cleaning devices.”

One Solution: Mechanized Air Cleaning Devices

  • Air cleaning devices, come in many forms, but one common type is medium efficiency air filter installed in a special housing on duct systems. These usually have an accordion appearance and are 80-90% efficient.

  • The other common type is the high efficiency (up to 99.9%) HEPA (High Efficiency Particulate Accumulator) systems installed on dust systems or as stand alone units. HEPA systems on ducts usually require additional fans to push the air through them. Stand alone and portable units also generate sufficient air flow to filter the air. These can filter down to 0.3 microns.

  • There are also often adsorption filters that contain activated carbon to filter pollutants in the form of gases. The gas particles adhere to carbon as the air passes through the carbon filter.

AllerAir offers many high-quality, all-steel construction, portable units. Most units have HEPA and activated carbon. A UV lamp can even be added to sterilize bacteria, viruses, and mold present in the air.
