I am unsure about these types of filters. I’m a big fan of bongs/bubbler and don’t normally smoke joints. However I do know of moose labs. They have filters for joints, bongs, ect.
If this is what you’re talking about then I think the reason for this is glass had pipes have such a huge array of sizes that it’s hard to make a filter for them.
I appreciate that very much. I skimmed it and will be looking at it later. I did notice you mentioned desktop vapes.
I actually recently got a ball vape. The SS zeal and I absolutely love it. Changing Temps from low to high depending on when I’m smoking is the best. I’m about to smoke/vape now.
