HEPA filter can actually be washed and is moisture resistant.

There is no need to wash the filter after every cleaning, it makes no sense. Even if the filter has turned grеy, it can perfectly trap dust.

It’s time to wash the HEPA filter if the suction power of the vacuum cleaner has decreased. First, tap the dry filter on a hard surface. Then, under running water, gently rinse the entire surface of the filter WITHOUT using brushes or detergents.

After washing, dry it at room temperature. The filter takes 1-2 days to dry.
