Air purifiers are increasingly proving their value as homeowners wake up to the benefits of improved indoor air quality.

Homeowners unfamiliar with air purifier science need to know that air-cleaning devices are designed for different types of airborne pollutants. For instance, inexpensive fiberglass air filters trap larger dirt particles rather than the smaller pollen, dust mites, and pet dander particles that may adversely affect occupants’ allergies.

If you plan to install a device to improve indoor air quality, be sure you study up on air purifier science. Read on to learn more.

Air Purifier Science: Different Types

Mechanical Filters

Mechanical air filters are the types you change regularly in your HVAC system. Many homeowners opt for inexpensive fiberglass filters that effectively trap larger dirt particles for about 30 days. To trap smaller particles, it’s recommended that you install a pleated filter made of denser material that can capture a wide range of minute pollutants. These should be changed as manufacturers recommend — or more often if you have dusty conditions, shedding pets, or you burn candles.

Washable Filters

Washable filters are generally designed to catch particles with an electrostatic charge. The particles are collected on a plate which must be cleaned regularly to be effective.

Ionization Filters

These filters work in a similar way as the types that catch particles with an electrostatic charge, but they give off ozone molecules as they capture particles. Ozone is of concern to those with allergies.

Ultraviolet Germicidal Irradiation Air Cleaner

The UVGI method is another example of the varieties of air purifier science. UVGI technology uses ultraviolet lights installed in the HVAC system to disrupt the DNA of living pollutants such as mold, mildew, fungus, and germs as they travel in the return air from the home into the HVAC.

Activated Charcoal Filters

These filters use activated charcoal to remove gases such as cigarette smoke and other vaporous pollutants by means of a process known as adsorption.
