Glass Carbon Filter Adapter – 18mm, Female Top/Male Bottom Diffuser

Our Standard Glass Carbon Filter Adapters are handmade and feature a glass 5-slot diffuser to keep the carbon in place and provide maximum flow. These carbon filter adapters are a great way to retrofit an existing piece, while filtering out carcinogens and toxins in the smoke for improved taste, smoother hits and cleaner glass. The standard measures approximately 1.5” in length.
The Ultra Glass Carbon Filter Adapter holds more cotton or carbon. Some folks like the extra room and feel it gives them even more smoke filtration. It stands 3 inches high which makes the pipe taller than using the stumpy filter or the standard.
