Filter Tip Inserts - Doob Tube add-ons for joints and pre-rolls

Our patented Doob Tube joint and preroll filter tips do an amazing job of blocking resin, tar, and red-hot flower bits, protecting your tongue and throat from nasty burns. No more burning material in your mouth - just clean and cool smoke!

Doob Tube Filter Tip Inserts are designed to fit in our smell proof and watertight DOOB TUBE CASE—discreet, smell-proof carrying cases for your joints. These filter tip insert replacements work with most joints, blunts, and pre-rolls, and they're easy and fast to clean with isopropyl alcohol.

Our new nano crystal CHARCOAL FILTERS fit perfectly into these tips to further filter the smoke from residual resin and tar making smoke even more pleasant to inhale 

How to clean silicone filter tips

Once the screen plugs up with gunk, resin and tar and you can not inhale through it you can simply drop the filter tips into the ziplock bag or small jar and add isopropyl alcohol for few hours and rinse under water. You can also use Q-Tip gently to swirl on the screen without pushing on it.  Please watch the video below
