Dr. Perl Jufifty 6mm Activated Charcoal Filters x 50

I purchased a box of these to try them in some of my balsa, Grabow and Medico filter pipes. They are well made and fit all but one of my Savinelli pipes. The one that doesn't fit takes balsa filters just fine, but this filter will not go into the stem far enough to use it. As for the Grabow and Medico pipes, they fit just fine, but you can't push them into the stem all the way. If you do, you will need a pipe cleaner or a piece of wire to push them out. These are much shorter than the paper filters so I just leave them sticking out of the stem about 1/4" and that works just fine. Before I put them in, I give a short blow to clear out any charcoal dust so that it doesn't end up in my mouth and ruin the flavor of the tobacco. These do a much better job than the balsa and paper filters and I don't get tongue bite. I only get one bowl out of a filter since these are small and they absorb a lot. Just ordered a second box.

Little tight in the Missouri Meerschaum I'm currently in love with. But if you know how to relive material from the peg, you'll be just fine. The shorter length is nice, I despise screens and the Savinelli protrude almost into the chamber and get clogged with tobacco. Savinelli's cost about 36¢ a piece and get 3 uses. Dr Pearl cost about 20¢ a piece and get 2 uses. So for every 6 smokes Sevinelli is 72¢ and Dr pearl is 60¢. There's value in these. They both smoke the same. And the Germans are better at manufacturing than the Italians anyway.

These filters are good and fit in 6mm pipes. The draw through them is pretty tight though. I can't speak to weather they really cool down your smoke, because the speed it allows you to draw through your pipe would cool down your smoke by default.

I went to pipe tobacco to help quit cigarettes. I use filters because they do filter a lot of tar and gunk (you'll see when you remove them after a few bowls). They also stop any particles or embers from coming up the pipe stem. I think these filter better than cigarette filters, with the charcoal. They fit most of my 6mm pipes just fine since they are short in length (Savinelli, corn cobs) although I did have to lightly sand the stem on a few of my cobs to get them to slide in. I use a small set of pliers to remove them since they get REALLY dirty (which means they're working). You also want to remove them when wet and be careful, if you rip them in half the bottom is stuck in the pipe and charcoal bits get everywhere. That's normal though for all charcoal filters. These flow better than a few of the other charcoal pipe filters I've tried.

Would not fit in my 6MM MM corn cob. Not worth returning. It would take 15.00 in gas to do it.

I genuinely like this filter… I’ve used other cons before, but it they tend to still leave a strange after taste in my mouth… this filter really helped out a ton. Some people do complain that it makes the pool fill a little tight, and it’s true that it does increase the draw effort but for me I like it because it protects me from tongue bite if I’m using a sweet aromatic blend.I will definitely be buying more if these

Hard luck. First one I pulled was almost clogged. Hard to breathe just through the tube alone.(testing it).

These filters are a bit too wide and have to be jammed in. The draw is very poor.
