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 actually went on vacation the day it released. I installed it on my deck to be able to play when at the hotel. I put 14 hours in starfield on my deck. It's PLAYABLE but not really ENJOYABLE. You have to turn it down to almost the lowest setting to play it reliably.
