Foam Air Conditioner Filter Replacement

I purchased new foam filters for our Dometic Air Conditioner but foam material want let much air through, found some at Lowe's for window units that is a little better but not like the one l am currently now using in the A/C. No problems with the one l am currently using but when l try the new filters they cause the A/C to heat up and flip the 20 amp breaker, l cleaned A/C coils early spring, l try to keep the A/C maintenanced. Plenty filters to choose from on Amazon or Ebay but what are y'all using that works good?

I use the originals that came with my Colemans. They flow well, clean easily, and after 3 years of use the coils still look good. Why do you need to filter that fine? These units really need as much airflow as possible.

That's my problem all that l have ordered are to fine, l am having a hard time finding one that will let as much air through but still do a good job catching dust. I have one in now that is working well but l can not find any more like it.

I saw some replacement filters at Walmart in the RV section today while walking through.

What I did was to install 8 X 10 metal filter frame and mounded it over the original filter. I cut my own filter out of a larger piece of good quality filter material. Better filtration and better air flow. You have to make a larger frame out of wood or vinyl(I used Vinyl) to mount the metal filter frame in. Works good last a long time.

Good idea, if and when you get a chance could you take a few pictures of open, of filter and how you mounted it on the inside? I am going to use your idea. Thanks Marty

These are some pictures you requested. I made the frame out of vinyl(1.5 X 3/4" material) Unit is mounted with 2 screws from top through the original filter frame. A wire mesh is inserted to support the filter material. You can purchase the filter material on line in 24-36" length. If you were to need additional info I may have a drawing of the vinyl frame.
