Our new carbon activated joint filters fit perfectly into these tips to further filter the smoke from residual resin and tar making smoke even more velvety smooth.

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:
