Vauen Dr. Perl Junior 9mm Activated Carbon Pipe Filters, 100 Pack

I am very satisfied with these filters and will reorder them as needed.

In California the herb is legal. So I did an experiment to get a cleaner sesh. I taped two glass tubes with 9mm inside diameter together with a filter between, to see how well the filter cleans the tar. This is the result. You can see the glass tubes before ad after the filter, smoke inserted on right end (blackened). Photos show clean (0), and after smoking 1, 2, and 6-8 herbal smokes (420). I replaced the filter after four, th en smoked two to four more. These really remove a lot of tar! But none of the active compounds. The golden color in the left tube is the cannabinoids we like to consume.

Good value. Fits my pipe well

Bien

Fits perfect,Last a long time.

Muy bueno

In this day and age, we all know that inhaling tobacco is not the best thing for our lungs. However, if you must, then you must do something about that smoke in your lungs. These filters remove a great deal of the harmful elements while leaving the smoke cool without much if any negative effects on the flavor of your product. I recommend these filters whole-heartedly!

Product is great but a day or two late without fail.

Works as intended. No complaints, will buy again.

Die Pfeifenfilter von Dr. Perl sind sehr gut.

Ideal para pipas con filtro 9 mm

I bought a pipe that came with filters and then used them up so bought these. These are brilliant and if you open one, they are filled with charcoal that absorbs some of the gunk...the pipe i bought had filters filled with ball bearings?! These are a brilliant replacement.

Pipfilter som fungerar utmärkt !
