Take your Waterpipe hits to a whole new level of comfort with the Filter Kit - brought to you in collaboration with MooseLabs Each triple layered Carbon Filter removes resin, tar, and other contaminants from smoke, helping deliver more of the good with less of the bad in each dramatically smoother hit. Place a filter inside the Filter Holder before inserting it into the Waterpipe mouthpiece to start enjoying a more comfortable hit. Replace the filter every 5-10 hits or when heavily discolored, then resupply with more Carbon Filters when ready.
