Ceiling Air Cond Filters

[rk911]

2016 Itasca Suncruiser 38Q. we have two roof AC units and on the ceiling of the coach there are 6-cold air returns each of which has a small round filter. I've pulled each of their frame and dry-cleaned them using my hand to beat out the accumulated dust and then re-inserted them into the frame and replaced the entire assembly into the ceiling.

question: is this the best way to clean these filters? can they also be cleaned by running them under a stream of water? if yes, how dry must they be before returning them to their frame and ceiling? if the filters become damaged where can I find replacements? the Winnebago owners manual is silent on these questions?

question: are filters also located in the units on the roof? where would the filter(s) be for the heating system?

thanks.

If yours are the sponge type filters, those very thin sponge things, just run water through them from the back side so the dust falls off with the flow of water. I wring them out by hand with my fist (one hand), and then put them back. They are not perfectly dry, they are still damp, but they dry out very fast once air starts passing through them. I've been doing this for the last 15 years and it hasn't hurt any air conditioners I've owned yet (in the camper or window air conditioners in a house either).

thanks. I have those same filters. and thanks to the other posters I now have a source for the material. think i'll order one piece and keep it in reserve. appreciate all of the help.

You can get a sheet of the same material at most RV dealer parts outfit or even at Home Depot and cut to match the existing.

X2, I replace mine every spring and wash every month that I'm on the road.

(I have brushed them clean (Very soft brush) patteded/knocked as you have, and used water.. I think dry methods work best.. However the filters are generally waterproof plastic.. Though they do make "Cloth" (fiber) filters I've not seen one in RVs.

so no filters on the roof, ok. how dry do the ceiling filters need to be before putting them back in place?
