User Review: Katadyn Micropur MP1 Purification Tablets
Price Paid: $15
I use these tablets in conjunction with my MSR Miniworks EX filter to catch viruses. These tablets are small, light, and leave no lingering taste in the water. They're also handy to have around in the event of an emergency, especially since they will kill Crypto (takes four hours for crypto, 15 minutes for viruses).
