What is a HEPA Filter

HEPA Filter

HEPA stands for High-Efficiency Particulate Air. HEPA filters are advanced filters that create cleaner air than traditional air filters. These air filters are tested and approved by The Institute of Environmental Sciences and must trap 99.97% of particulates 0.3 microns or larger in order to be categorized as a HEPA filter.


HEPA filters draw air through them to trap pollutants such as dust, dirt, pet dander, and other harmful particles and pollutants. By installing a HEPA air filter in your home’s heating and cooling system, you’ll trap all the harmful particles that could trigger or worsen asthma or allergy symptoms.


Switching to HEPA filters in your home is one way to improve your indoor air quality, but it’s not the only way.

Change your air filters

How often you use your heating and cooling system will determine how often you should change it out, but as a general rule of thumb, you want to change your filter every 30-90 days so that air can filter through unhindered by the dirt, dust, and other particles the filter has picked up.

Bring the outdoors inside

Keeping plants in your home can help clean your air naturally! Plants that can improve the quality of your air include Peace Lilies, Aloe Vera, Spider Ferns, and Dracaena. Make sure to do your research though–some of these air-purifying plants can be toxic to pets.

Ultimately, HEPA air filters are only as effective as you allow them to be. Maintaining your heating and cooling system regularly and getting your air ducts cleaned annually will ensure the air you breathe is healthier for years to come.
