Purize Aktivkohlefilter | Regular Size | 9mm | Regenbogen

Bought a pack for a friend and ended up keeping half for myself—the 9mm size fits perfectly without any fiddling. The rainbow finish is a nice touch, and all 50 filters were consistent in density, which I appreciate.

The rainbow colors on these filters make them easy to spot in my stash, and they actually do a solid job smoothing out the harshness without clogging up after a few uses.

I was pleasantly surprised how much better the smoke tastes with these rainbow filters—the charcoal really pulls out the harshness without restricting the draw. The 50-pack is a solid value too.
