Furnace Filter modification

Hi, with all the talk of sail switch failures, I decided to try and prevent any lint or dust from entering fan / sail switch compartment. My 19’ is over 1 year old and has not had any problems as of today. When I did this mod, I checked the sail switch and it did have some white lint built up. What did I do?

1) Removed furnace and sealed up compartment completely with expanding foam. Upper and lower gaps, corners etc. Once the foam cured I then trimmed to make it flush and neat. I did not take a picture once I trimmed it.

2) I then took the front grill apart and cut a furnace filter to fit around exhaust. I held this in place with aluminum foil tape.

3) Reinstalled the front round air deflector, and secured the collapsible vent hose with new zap straps.

4) Put the furnace back in and mounted all the screws.

It works really well and you can tell a slight difference in air flow / fan noise once you put the front wood plat back on. Meaning the only air it is getting is through the filter. It does not restrict air flow enough to hurt the fan.

Let’s hope no future sail switch failures!

Cheers

That should work and a must do if you have any furry friends with you.

Thought about this same approach- using furnace filter material. However, I was uncertain whether or not the glass fibers in the filter might cause the same problem (fibers getting into the sail switch) as the white fibers that come from the unknown source. Please update this thread once you have used the furnace a bunch of times.

I ordered the charcoal filter material that someone else had provided a link to a while back. But when it arrived it was very dense, I think intended to filter water rather than air, looked like it would severely restrict air flow so I am now looking for a much thinner A/C filter material.

Going to give this material a try.

Nice work but just a word of caution....

These furnaces are very sensitive to proper airflow. Escape uses the low amp model furnace for less battery drain when boondocking. It is not rated to handle really any external resistance. This includes the return air path. The filter you show is MERV 8 which can have a decent initial resistance (clean) especially at higher velocity generated by that small return air area on the grille. Plus we need to remember that this is going to catch all the dirt now and will load. A loaded filter will restrict airflow even more. Possibly not enough to cause the sail switch to not make, but enough to cycle the furnace on high limit. Since these furnaces have a fixed fan speed and non-modulating burner the increased resistance will cause a reduction in airflow which will cause a larger temperature rise of the air across the heat exchanger. The high limit will trip at 190F. You may want to look into a material with less filtering efficiency or treat this as a maintenance item with regular replacement.

Would the wife nylon socks do the trick for the filtration on the air?

Air restriction is currently very minor..... will keep an eye on it and appreciate the input. Unlike a house furnace filter ... the relative use will also be minor so expect it to last several seasons. If not, a 10 min job to replace.

I bet something very thin like the screening on the A/C intake would work, or something even more open - just want to keep out big dust bunnies, cat hair, etc. not every dust particle like a regular A/C filter is designed to do.

Somewhere out there is the perfect material waiting to be discovered....

Ever since I was caught with a pair of panty hose in the glove box, I have been using them for an air or paint filter......
