screening an AC unit to keep out debris from the cooling fins

Yesterday I spent most of 3 hours hosing and picking out cottonwood fuzz and other debris from the cooling fins of my 2 outdoor AC units. I

usually do this once a year after the cottonwood stops. I missed last year. I was thinking of using screen door like mesh to wrap around the outside of the units to make them easier to clean. I thought about cheap furnace filters. Any intersting solutions out there? I googled AC

There is a company that makes filters for industrial cooling towers. They use a polypropylene mesh. It is not as fine as a filter, but is fine enough to keep out leaves, the cottonwood stuff,etc. It is washable. If you can find the right material, you can make your own.

Inside you want fine filtration to clean the air you breath. Outdoors, you only have to keep the debris that clogs the fins.

Absolutely. I was thinking that rather than metal mesh, I might try to dig out some sort of plastic type flexible mesh.

With a number of cottonwoods in the area, the last thing I wanted to do was to spend hours cleaning my new Carrier A/C. I got some fiberglass screen cut to length from a hardware store and magnetic strip. Cut the strip to length, drilled holes for the screw heads and put the screen under the strips. So far so good after one summer and two winters.

I ordered some polypropylene mesh (.03x.05" mesh size) from McMaster-Carr yesterday. I think it's here today (by e-tracking). I already have magnetic strip rolls from the portable car moldings I made several years to lessen the auto dings on my then new car. We'll see. I heard about the fiberglass mesh from Ace hardware, but wondered if the flow might be restricted?Cheers
