What is a medical-grade HEPA filter?

This is a kind of filter that is commonly found in an air purifier used in hospitals. Usually, medical-grade HEPA can range from H10 to H14 but the H13 type of filter is the most commonly used one in air purifiers in the market today. Let’s have a look at the differences between H13 HEPA and regular HEPA:

Feature Medical-grade (H13) HEPA Regular and True HEPA
Percentage of particles removed from the air 99.95% 99.97%
Size of particles removed 0.1 microns 0.3 microns

As you can see above, air purifiers that use H13 HEPA can clean up even smaller particles as compared to regular and true HEPA filters. The percentage of particles removed is not that different but if we look at the size in microns, we can see why H13 is a medical-grade type of filter. This means that it is more applicable for hospitals where airborne viruses, germs, and bacteria are more likely to spread out.

Do air purifiers reduce germs?

Yes, but it depends on the air purifier that you have. For instance, many powerful air purifiers, such as medical-grade ones, can trap smaller particles, which includes germs, viruses, and bacteria. It also helps if your air purifier has a UV-C light, which is a disinfectant.

What air purifiers do hospitals use?

Many of them use a portable HEPA filter for hospitals because they are easy to transport. However, they also need to be medical-grade or H13 true HEPA so that they can clean the air more efficiently to ward off sickness-causing germs, bacteria, and airborne pollutants.


In the long run, buying a medical-grade air purifier will help you and your family (and guests) to breathe better air, especially if you have someone with allergies or asthma around the house. By filtering smaller particles, your air will be much cleaner than with regular filters. Furthermore, it will be a great advantage if your living space is in an urban area where pollution is a big problem.
