HEPA filters or High efficient particulate air filters do the majority of the work when it comes to the actual air purification process. These filters are designed to catch the smallest particles in your home, oftentimes down to 0.03 microns in size with really high-efficiency levels. They capture mold spores and bacteria, virus carriers, VOCs, dust, dander, pollen, smoke, smog, and any other airborne particles down to 0.03 microns (which is very small).
HEPA filters are used in many everyday places, yet you probably never notice them. In addition to being used in home air purifiers they are also used in airplanes, hospitals, and clean rooms, cars, HVAC systems, dentist offices, and many other places. . However, not all HEPA filters are the same, and some work better than others. HEPA filters are rated on the MERV scale (Minimum efficiency reporting values) which gives a score to filter based on the minimum size of the particles it can capture and how efficient it is at capturing them. As a rule of thumb, the higher the MERV rating (usually between 8-20), the better the filter.
At Breathe Naturally, we pride ourselves on providing top-quality MERV 17 HEPA filters for a fraction of the OEM cost. Our Breathe Naturally HEPA filters stop 99.97% of particles down to 0.03 microns small. These filters are perfect for people who suffer from bad allergies, respiratory issues, those who have pets, or live in a high pollution area (which can include most medium to large cities). We recommend changing HEPA filters every 4-6 months based on use. Those who put more “stress” on their air, such as having a consistently high amount of people frequent common spaces, people with multiple pets, smokers, and people who live in high pollution areas may want to change their filters more frequently. Most air purifiers today come with filter change indicator lights that tell you exactly when you need to change your filters. You can dispose of your dirty HEPA filters quickly and easily in the garbage, no special process is needed.
