We're getting ready to leave the great white north for Phoenix in a couple of days and I got to wondering about the need for some type of air filter in the motorhome for long term use.

This is our first year doing the snowbird thing, so in years past we didn't use the furnace very much, as the motorhome was in storage during cold weather. I know that the furnace will be used quite a bit in January and February, and we have a dog and a cat with us. So, with all the usual dust, and the pet dander, does anyone use some type of air filter? Hepa filter?

Which brings up another question. Why isn't there an air filter on a RV furnace? Or is there one and I just don't know about it!

I don't think there are filters on the furnace. But even if there were, they would not be up to HEPA standards, as those would not allow enough air flow. Probably a standalone air cleaner would be your best bet.

Hi All,

Hey Shanwick, my wife cut furnace filter to fit each blower vent, it was done more to keep stuff from falling in! We have been useing this system for about6 years now! I know it does not restrict air flow, since temps were 16, 17 & 24 and it was nice and warm inside !!! Not sure how it works for air cleaning, but we seem to be healthy,LOL !!!!

Jeff,

It depends on who made your coach and the previous owner. My current coach has the furnace filter under the bed which is shared by the AC system. On my old coach the furnace return was under the dinette and the previous owner had enlarged it to take a floor mounted filter.

Jeff,
Don't know why there is not a furnace filter on an RV Probably to save money. Not a bad idea to have one though. I installed filters on the return air for our furnaces and used 3M filters (not HEPA). Not sure how effective it is but I feel better knowing they are there. Probably not a bad idea to somehow replace the foam AC filter with a real filter.

Beware that if you install a very restrictive filter you may be harming the system performance by restricting the air flow. An unintentional by-product may cause the furnace to cut-out when the internal temperature rises.

I have a furnace filter in the floor under a closet in the bathroom. There is a return air grill in the wall under the closet and the filter is behind that in the floor. We don't use our furnace very often, so it rarely needs to be replaced.

You are absolutely correct Fred. I found a filter box that allowed for a 6X12 inch filter that sits behind the return air.

Propane RV furnaces have no filters because a dirty filter could cause your furnace to overheat and cause a fire.

Basement AC/heat pump systems do have a filter because there is no flame.

Tom,

I guess part of the reason I asked the question was that the first house I bought many moons ago, I didn't look closely enough at the HVAC system before plunking down the money. Big mistake. The previous owner hadn't used a filter for years on the gas furnace. Thus, the squirrel cage blower was coated with crud, which I had to clean with a tooth brush.

I understand that proper air flow is a requirement for the furnace to operate. That's what I thought a sail switch was for. Not enough air flow, no fire in the furnace. So I guess my question is still how come they don't design these things with a large enough blower unit to accomodate some sort of filter. It doesn't have to be HEPA, just a normal type of filter. It really wouldn't take that much more power. I suppose most people don't use the furnace enough to worry about it. But, I wonder what fulltimers do after a few years with no filter. Or am I making a mountain out of a molehill here?

Thanks for all the replies.
