Clear beer & wine wins awards and impresses those we share it with. BevBright Cartridge Filters are an inexpensive, easy to use, and effective filtration media that your customers are sure to love! BevBright the first high-efficiency, multi-zoned, disposable cartridge filter available in the Homebrewing & Winemaking market. Current spun cartridge filters have 60-80% efficiency ratings, meaning they let a lot of the material at their given micron rating pass right through the filter. BevBright least efficient filter boasts a 90% rating, and they only get better from there! The multi-zoned construction weaves coarser fibers on the outside of the cartridge and finer fibers on the inside. This approach allows the surface of the filter to catch a lot of the larger sediment and the interior to perform the "actual filtration." The net effect? It takes a lot longer for these filters to clog up and virtually eliminates the risk of blow-by. And perhaps the best feature of all: These filters are so affordable that we recommend just tossing them in the trash when you're done! Save your customers the time, frustration and risk of trying to clean and sanitize the filter cartridge. 1 Micron Filters Your customers should use a 1 micron filter as a final, ultra-clear polish only when their product is already very well settled. Excessive yeast or sediments in solution will quickly clog up a 1 micron cartridge. Product that is cloudy in appearance from anything other than a protein haze should be run through a 3 or even 5 micron prior to 1 micron filtering. In many cases the single coarser filtration will be all they need. Which Efficiency is best? Every batch & brewer is different. Some customers will find that their processes or ingredient choices naturally yield clearer or cloudier product.
