I cleaned a pleated HEPA filter for my vacuum cleaner.

I want to dry it out.

I ran 70% IPA thru it to draw out the moisture, but it still has some
residual moisture in it after 2 days.

Any other ideas to try?

Would putting it in the fridge for maybe a week help since the fridge
does a good job of drying out food. :-)

Thanks,

Alcohol sucks in moisture. I would, set it in the sun, or run it in spurts
in vacuum to clear openings.

If it is not a "washable" HEPA filter no amount of drying or sucking
will restore it. it is FUBAR. If it says "permanent" it is NOT
WASHABLE - water destroys it PERMANENTLY
