There are many kinds of materials that make up HEPA, which can be divided into PP (polypropylene) high-efficiency filter paper, PET filter paper, PP and PET composite high-efficiency filter paper, and glass fiber high-efficiency filter paper.
PP (polypropylene) is paper, so it generally cannot be washed.
The other part of the HEPA filter is made of PET or H13 high-efficiency filter material, which is why many claims on the Internet that the HEPA filter is washable.
