Inexpensive Screens?

I was thinking of using cheesecloth and maybe coffee filters to strain instead of bubble bags. A set of bags for $500 or whatever (bubble now complete kit) that can last "100 times or more", thats cool and all but I'm thinking in the next couple of months, I only need 1 time. There's a 1-gallon 4-bucket kit for $95.. But I'm sure I don't need to spend that. Can anyone think of anything waterproof that would serve this purpose? The smallest bag is around 20μ (microns), I'm not concerned about separating the 50μ from the 75μ etc. Just removing the bulk matter and keeping everything else.

Ideas?

I was thinking of buying the three most crucial ones.

I would never buy the "bubblebag" brand bags because they are so expensive. I have the wacky willys bags and they work great, I think I payed like 60 or 75 bucks for a 5 gallon all mesh kit.

I found a great deal on those wacky bags, all mesh and with drawstrings.. three 5 gallon bags in 220, 90 and 25 microns, for $60. Also ordered the pressing screen and the 20mm hash press, for another $7 and $25. Thanks for the heads up DH.

If you are interested, I will have a new product for testing. I have one gallon, 220 micron, all mesh bag that are perfect for a coffee can and the dry ice method. I got them made as a test product. My only request is that you write a review or do a video on youtube.
Send me an email and I will send you a sample. dm
