What do you guys use to filter the air for your fluid beds? I've heard of coffee filters to brown paper sacks.
I use brown paper lunch bags. I tryed coffee filters, and vacuum cleaner filters. The brown bag works best for me.
I buy the cups with the membrane in it. I also use a bought fluid bed and not home made kind though. I know some use the coffee filters. Other than that I don't know.

Hi, I"m making my own fluid bed, and I hear you all talking about what you use. Seems to me a coffee filter would work better than a brown paper bag. Is the coffee filter too pourous? I haven't tried it yet. I guess trial and error, as I have both.
When I tried the coffee filters I had too many volcanos. The brown paper bags had a few with certain colors and other colors had none. They have to be the lunch size bags.Quote:

The other is made from a PVC Reducer. The PVC cups fit down into the reducer and present a larger gluing surface for the brown paper lunch bag. I also have used vacuum cleaner bags.
I have an in-line pressure adjustment valve which prevents the volcanoes.
The commercial ones use a porous plastic of some kind.C2
