Did you know that with some very minor changes in your home, you can reduce the amount of allergens present, and improve indoor air quality? All it takes is a good HEPA filter or two. Learn more about HEPA filters, how they work, and what in-home filters you can replace with HEPA-certified variants in our guide below.
What are HEPA Filters?
HEPA is an acronym that stands for High Efficiency Particulate Air. Filters that meet the HEPA standard remove the vast majority – 99.97% – of particles from the air that passes through them, provided the particle size is greater than or equal to 0.3 micrometers in diameter. For the sake of putting that in dimensions most of us are familiar with, the width of a human hair is typically 50 micrometers. So, the HEPA standard filters out particles which are around 150x smaller than the width of a human hair.
How HEPA Filters Reduce Indoor Allergens and Improve Air Quality
Many of the most common indoor allergens, dust, pet dander, pollen, and other allergy triggers in the air are made up of small particles. By using HEPA filters, these particles are trapped in the filter rather than allowed to continually circulate in your home. Most home heating and cooling systems will theoretically run . . .
