I just saw a video where the RV owner washes his AC filter to improve air flow. In my experience, even a clean filter is so restrictive that it severely limits air flow. In fact, on the hottest days I just remove it and the flow seems to go up about 25%. Is this something you've done?


There is something special about camping in an RV.

Never and it's just plan stupid. Without the filter you are allowing the dirt to collect on the coils instead of the filter and blocking air flow thru the coils!! You cannot get to the coils to clean without going on the roof with special coil cleaner that is hard to buy and unsafe to use without proper training.

you are wrong. you can clean most rv evaporater coils from the inside of the rv without caustic/acidic chemicals. you aren't wrong about the dirt collecting on the coil if the filter isn't used.

I wouldn't remove the filter, it has a job to do.....just like your engine oil filter.

Yes, just like home systems if you run without filters the air flow will be better. One of the reasons RV furnaces don’t have them. But as mentioned you will eventually clog the cooling fins which are harder to clean than the filter.

None of my AC filters have been the least bit restrictive. To the contrary, I figure they do very little and I suspect I could read a news paper through them.
I would never take them out though, that would be a foolish mistake.

The manual says to clean the filter, so I clean it.
It is a five minute job

+1 When the wife has the central vac hooked up I pull the filters and run the wand over them. One minute and they are clean.

OP If you keep taking the filters out to gain that 25% more air flow, it won't be long before you are losing 50% all the time.
