I have a heat pump/AC system with a washable air filter. I was told to clean the filter out and run water through it once a month.
He told me to let the filter dry for 3 hours before replacing it. I had a different tech tell me, however, to shake the water out of the filter and put it right back in.
So that leaves me with two questions.
- Is it safe to run my AC/heat without a filter for 3 hours?
- Is it safe to put a wet filter back into the unit?
Thanks for all help in advance!
edit: My filter looks something like [this one][http://i0.wp.com/www.anthonydpmann.com/upload/2017/09/28/goodman-permanent-filter-to-fit-in-goodman-air-handler-goodman-furnace-filters-l-8c8fd9b9ed6663af.jpg?w=200&strip=all] and measures 15 x 21 x 1. I looked around and was not able to find any disposable filters that size. Would it be safe to use a disposable one instead of the permanent one?
