What is the true HEPA air purifier and What is the H13 air purifier?

There are no different types of HEPA filters: a filter either conforms to the HEPA standard or doesn't. This includes filters marketed as "HEPA-Like", which may look like HEPA filters externally but do not perform to the required standard. However, there are different HEPA filter grades, ranging from H10 through H14. The higher the grade, the higher the performance.

 

H10 to H12 filters are sometimes known as "True HEPA" filters. They trap fewer particles than the higher-grade filters. H13 and H14 are known as "medical grade" HEPA filters. These filter 99.95% and 99.995% of all particles down to 0.3 microns, respectively.
