Does anyone sell a conversion kit to allow using a disposable paper filter on a Coleman A/C? Looks like a 16" x 16" filter would be the size. Otherwise I feel a project coming on.

You probably will have much less air flow, maybe you could build a larger frame for a larger paper filter.

Just keep in mind the air filter is meant to remove large particulates and allow small particulates to pass through the evaporator. It is not meant to clean the air you breathe. A "paper filter" by its very nature will create a large restriction, reduce air flow and increase head pressure in the compressor. That is not a good thing.

What he said. A paper filter will be a significant flow restriction.

What they say. Plus this will more then likely cause freezing and icing.

I’ll be somewhat contrarian here- if you can use the full 16x16 I think you will be fine. The a/c in our park model uses a 12x12 filter, and that’s on a 2 ton unit.

So, what are you trying to filter out? You need to know the particle size. (really the range of sizes and the material, the loading, air velocity, acceptable pressure drop, etc.)

Do you mean pleated or paper? When I am president I will make sure that all ACs, including window bangers, RV and minisplits all use at least Merv 8 filtration at no more than 350 FPM faca velocity...:.

I was going to try this last year. Already have the filters and dont care what it looks like up there. Plan was to fold and staple a larger pleated filter into a box like shape and temp tape it to the roof. If i like it then maybe build a housing the accept a flat filter for easy replacement.

I got to think at some point a person with hvac experience has tinkered with their RV and measured the flow of a clean stock foam filter? Or maybe there is a spec on what the stock filter flows?

If we know the stock filter specs then it would be somewhat safe to use a residential pleated filter with equal flow at the correct velocity the RV a/c runs at on high?

Its dusty here and i want to keep the ducts clean is my motivation. I have an automotive radiator fan hot glued to a cardboard box with a pleated filter on it. Sometimes stick in the window and other times run in the trailer as an air filter.
