KMS BEERFILTER cartridges were designed specifically for beer filtration applications. Their new, inside-out microporous hollow fiber membranes use crossflow microfiltration technology to filter undesirable suspended solids without affecting bitterness, aroma, color, taste or foam stability. The result is a preservative free, shelf-stable product. They eliminate the need for Diatomaceous Earth (DE) reducing disposal costs and creating a safer working environment.
