Sanitary Air Filter

This versatile little filter is a beer maker's insurance policy! Whether you’re aerating or racking you will appreciate having the peace-of-mind of knowing that your brew will not be contaminated by whatever is floating around in the air. Use it anywhere you need to keep something sanitary. Both 1/4"" and 3/8"" tubing will attach to it, and it will snugly fit in any standard stopper as well.
