  • Works.
Material Type: UF-35 Filter Replacements
1. We noticed immediately that it improved water taste. 2. When I replaced the filters, out of curiosity I weighed the old (after clearing of water) and the new. The old ones, after 9 months of use, were significantly heavier than the new ones - one of them about ½ pound!' So they're definitely taking something out of our water! 3. The reason we waited 9 months to replace is because the replacements are pricey and we just didn't have it in our budget. But when we did - wow, the improved taste was obvious. Easy enough to install, super easy to replace filters. ... show more

Just bought this replacement filter set for the system we had installed about a year ago. The system works really well for us and we hope it continues to for many more years.
