Filters for the floor vents.
The home stores sell some small filter material made for floor vents of forced air heat systems. I wonder if anyone has ever used them on an RV floor heat system. Your thoughts and advice are always appreciated!

I like the idea, but am concerned that the typical RV furnace won't have sufficient fan power to effectively move enough air through the filters to adequately heat the trailer. That would mean that the furnace would run for longer periods of time than normal, consume more fuel, and if dry camping, pull down the battery much sooner. It could lead to an overheating situation and a fire hazard.
We've also heard a number of reports of damaged and deformed heat ducts causing similar reductions in heating ability.
Additional fan power is fairly easy to add, especially if running the trailer on shore power.
I am not trying to discourage here, but more thinking out loud. If you decide to give it a try, keep us posted on how it goes.

I’m just wondering why you’d put a filter on the output end of the system rather than the input. But given Steve’s comments, even that doesn’t sound wise. My intake is right below the fridge and now I wonder why there’s no filtering in the heating system. The A/C has it.

Joe -
On our Alpine, I was concerned that the A/C / Heat Pump unit did not have an air filter. I ordered some filtering material and Velco mounted on magnets that attaches to the intake vents. Seems to work quite well and does not throttle the airflow down at all.
However, for the furnace - no, there is not a filtering device except the "still air" area of the basement (on our Alpine, again). However, on our unit, I can see how a filter could easily be adapted to the "under stair air passage" along with the basement air circulation I devised. Unfortunately, I don't think this helps you a bit.
But, in my investigations, it seems like there are several "delivery air" filtering systems. However, Steve is correct - filtering should be on the return side rather than the output side. Think about only this point - air returning to the furnace to be heated and distributed, should be "cleaned" before it hits the "hot box" where nasty reactions could be driven.
We also purchased two "desktop" small Honeywell air cleaning units we leave running most all the time. Just cleans the air of the living/kitchen and the bedroom in general.

As mentioned above, RV furnaces do NOT have excess air flow. Putting filters on input OR output is not a great idea.

I was just reading the specs on my furnace and they state that the return register needs to be something like 65 square inches. It would seem that if your register is double that, you would be able to put on a filter that cut the airflow in half. Something like that.

Our Alpine has filters in the intakes of the heat pump and it's a pain taking them down and cleaning them

I've often wondered if ours should have a filter. It does not. The filters I'm using are easy to change and not really that noticeable.
However, I think the two Honeywell filter units we got from HD do really well.

They are glued to the backside of the inlet vents. Found them when poking aouund checking flows and such. So you have to remove the covers to get to them

Yup, checked there first thing. The inlet vent goes directly to the return duct work. Even went to the roof unit, pulled the cover off and checked there! Gave up and got the filtering material with Velcro magnets from Amazon. From the sounds of it, I think I'm happy I did!

i believe what Joe is referring to is the filters that go just under the floor vents to keep trash, dirt and whatever else that can fall through the vents from doing so. i use them in my home and they don't seam to restrict air flow at all and i am going to install them in my TT also. Phil
