Designed for ease of use and maximum yield. This bubble bag filter set features our proprietary stacking filter system. This system solves many of the pain points with traditional bubble bags. Crafted from premium, food-grade nylon mesh, our filter bags prioritize both quality and functionality. Our five-bag set also comes with 5 spacers and one collection/storage stand.  Our proprietary stacking filter system reinvents ease of use, allowing you to handle each bag with a single hand, streamlining your workflow. The inclusion of our spacers eliminates potential contamination by ensuring the filter bag never touches unwanted surfaces. Spacers and bags work with any standard-size 5-gallon bucket. This five-bag set, ranging from 220-micron to 45-micron, ensures a full spectrum yield with every extraction. Paired with the accompanying spacers and a convenient collection/storage stand, the entire process becomes a breeze.
