Oh! Good! Thanks for the tip. I'll check it out. The idea of easy
cleaning is getting more and more attractive to me.

Walmart carries this large dark green screening.. it's $3 a sheet, and is
reusable and durable. You can also cut it with a heavy scissors.

It comes in a large plastic bag, and walmart stocks a cardboard case of
them.. you just take as many as you need.

They are about 2 ft by 3 foot.

Just bought 3 more a few hours ago to increase my filter efficiency
