Review on 💧 Waterdrop RF15-UF 0.01 Micron Replacement Filter Cartridge: Ultimate Under Sink Water Filter Upgrade with NSF/ANSI 42 Certified Performance and 16K Gallons High Capacity by Kimberly Graxirena

Used this system for less than a year and had to replace the filter after a few months although the company claimed it would last a year. I bought it a few weeks ago and initially the flow was very good, but after 2 weeks it is already slowing down. upset. Must look for something else after this is clogged. Update: The company contacted and offered a replacement as they realized I wasn't happy with the last filter I bought. The last one I bought might just be a defect and hopefully this replacement will work and last as advertised. For their excellent customer service (Konstatin) I have increased my rating to 5 stars. Update #2: Had to change it back to 2 stars. They sent me 2 replacement filters and the first one I installed lasted about 5 weeks and the second one I installed in early May was already clogged. I noticed that the new ones were white and the ones they sent me (the black ones) might have been the ones they wanted to get rid of. I can't comment on white, but blacks aren't as durable as they claim.
