Boiling water for five minutes is the best protection against Cryptosporidium. But that’s a hassle. The following companies make products that can filter Crypto: Cuno, Inc. (203.237.5541), Everpure (800.323.7873), Multi-Pure (800.874.7873), Pura (800.382.3252), Sierra Pure (612.423.9732), Peterman Principle (312.540.0220) and Watts Regulator (508.688.1811). Make sure you ask for a filter that is certified “NSF Standard 53 Cyst Removal.” (If it says only “Standard 53,” it cannot stop Crypto.) The Brita Water Filter System does not remove Crypto.
