Review on 💧 Enhanced Sawyer MINI Water Filtration System for Improved Filtering by Alex Barr

. This product has everything you need to make hiking and water carrying easier. The filter system for the dialysis water made sense for the nursing staff. I bought this for my son with a 2 liter pack of platypus for a PKT hike in Oregon. I thought it was awesome. And that. Except that on the second day of his hike, the O-ring that forms the seal that pumps the water into the reservoir broke. Other PCT lovers knew the mini problem. Apparently the standard Sawyer filter doesn't have this problem. Sawyer Company - Attach the o-rings to your mini filter and you'll go from 1 star to 5!
