filtration

I'm finding myself stuck between two schools of thought regarding filtration and terpenes: 1. Too much percolation/water filtration will cause terpenes to be absorbed by the water, or being cooled so much that they stick to the glass 2. Too much air in a piece will cause loss of terpenes...

I'm shopping around for glass, and am considering getting a recycler, then using a recycler ash catcher along with it. Has anybody tried this? Will be using with a dynavap. Thx
