The other day I was brewing a collaboration with The Brew Professor and he showed me a simple yet effective water filter that hooks up to any hose. It was an RV water filter! If it can filter water for an RV, why not beer?
This isn’t a fancy RO system but it is a great way to brew with better water for very little money. The 100 micron fiber filter helps reduce some of the bad tastes, chlorine, and odors that can come along with public or well water. Treat your beer with love and pure water.
You can buy these for under $20 through Amazon and it is well worth the small investment. I really liked the simplicity of the Camco 40043. If you want to get even more fancy pants, add a Drinking Water Hose for less than $10.
