Customers say

Customers find the reverse osmosis membrane works well with their maple sugar setup and fits perfectly in old systems, taking only 15 minutes to install. Customers appreciate the taste, with one mentioning it removes chemical aftertaste from municipal water.

Good quality RO membrane

Antoine Rockamoraβ€”December 25, 2025

Supplying with fairly clean water (filtered to 1 micron, 230 ppm after softening, charcoal filtered) I got zero (<5) ppm; the membrane it replaced was at 30 ppm on the same supply. Rated 75 gpd; I got 38 gpd on 45 psi, supply water temperature 55F. This is a reasonable ratio of actual to rating; the membranes are rated at 65 psi and 77F. 100% would buy again. Read more

Great Filter, Works Good, Fits Nicely, Easy to Install.

GchanMakoβ€”November 2, 2025

These are nice replacement filters for our Krystal Pure K10 reverse osmosis system. This one is a little tricky to replace as you have to remove a water line, but other than that it fit well and works good. Read more
