Go right here and spend a couple of bucks for a cup with membrane already installed. Used the brown bags and they worked good but no comparison to these cups. Poke a hole in the bag and you got a real mess. That air filter can't hurt but I have never had a problem and it is pretty humid around here.

No need to replace. They are permanent, glued in. Just dump powder out into jar. I turn up side down and tap on little work table to get residue out. Reload and go. I have a shop with air compressor so every once in awhile I will blow a little higher pressure air from bottom out. Really not necessary just something I do. Main thing is no oil or grease on it. Moisture will stop it up until it dries out.

Not a very good picture. But it's no more than a 1 1/2 in coupling with a hole drilled in the side above filter and silicone D or glued in. I use mainly 1 1/2 in cups. But you can get the 2 in and do the same thing with a 2 in coupling. You just push the cup in as you twist it to get it to seal. Use a aquarium air pump to power it. Just a cheap one will do.
Thanks for all the info, but since my mind is like a sieve, can you give me those powder paint colors again? rotfl
