Four Types Of Air Filtration Systems You Should Know About

Improving the quality of air indoors is essential in improving your respiratory health. According to the EPA, the quality of air indoors is usually 2 to 5 times worse than the air outside due to the construction materials used in homes. Studies also show that most people spend approximately 90% of their time indoors, thereby increasing the rate of exposure.

Air filtration systems aim to reduce contaminants in the home. These residential filtration systems can be fitted to your heating or cooling unit with little or no modifications.

The market has four different types of air filters that can be suitable for your home:

Flat Filters

If you have a heating system, it most probably has a flat filter installed to protect it from large dust particles. Flat filters consist of a flat piece of fiberglass fibers put together in a random pattern.

The flat filters come in two options: pleated or non-pleated.

Pleated air filters are more costly compared to non-pleated filters and do a better job of filtration. Some pleated air filters are electrostatically charged to attract allergens such as pet fur and pollen.

One disadvantage of these filters is that they cannot filter out microscopic particles that might be irritating to your respiratory system.

Extended Media Filters

This kind of filter is considered superior to other residential air filtering systems because they contain many layers of filter material. The different underlying layers will catch pollutants that pass through the first layer of fabric.

One drawback of extended media filters is that they are costly and require installation into your home's ductwork. This means that you may have to acquire the services of a professional for the installation.

Ultraviolet Filters

Having the same goal of improving indoor air quality, UV light air purifiers are designed to inactivate airborne microorganisms using short-wave ultraviolet light. The filters are either sold as stand-alone devices or installed in already existing HVAC units. This filter is preferably used by hospitals and can be used by people concerned about germs in their homes.

Portable Room Air Filters

If you don't have any heating or cooling system, a portable room air filter is a more practical option. Some portable units use electrostatic precipitator technology, which does not use fans and costs less to operate since no filters require replacing. These filters require attic and duct installation to individual rooms.


Finding the right air filter is essential in improving the quality of air around your home. Houses contain a variety of pollutants and pathogens that can be detrimental to your health.
