Review on 💧 Watts Reverse Osmosis Replacement Filter Set: 5 pcs with CSM 50 GPD Membrane - Efficient Water Filtration Solution by Charity Johnson

Overall good product but not the best filter quality. My main concern is that despite claiming this is for the Watts W-525, the polishing filter will not fit. The one that came with the RO has push-in fittings and the one that came with the kit has threaded fittings so there's no way to get it to work. So while most filters work well, one of them is useless. I should have read the comments as it seems many other people are complaining about the same issue. Now I have to hunt another. Next time I will order something else.
