Air Conditioner Return Filter

[Steve Schempp]

My 2016 3970RD has two air returns on the back air conditioner. These have filters- card board and what looks like fiberglass material. I do not see any markings on these. Does anyone know where I can order replacements?

Thanks.

The filter material is foam in nature and you can buy a large sheet of it from Lowe's or home depot. You can run water o the foam in the sink and rinse it of dirt...but not the cardboard part.

We also buy from Lowes, and cut to fit.

We'll see with this 2017, but I always bought walmart replacement filters for window units and cut several out of each sheet. Took one of the covers out this morning and cut a pattern out of cardboard and will be cutting filters to fit during tomorrows NASCAR race

Since IMHO the only serious racing is F1, that seems to be a great thing to do during a NASCAR "race"!

I just wash the falter parts in worm water and blue dawn. re-staple to the card board and all is good.

Indy car is pretty good also but you cant beat open wheel road racing.
