Filters came quickly and were very easy to install.

I like that it seems to be working although it's very expensive to change the filters. I add a little Himalayan salt to my water to replace the minerals taken out during the RO process. That salt is really expensive.

While I was not able to use this product, it unfortunately did not fit my very old system. But John Crean went out of his way to suggest alternate solutions and was extremely patient as we determined what to do.

The dissolved solutes was lower (8ppm) before I changed filters and put these in (16-18ppm) but I should measure them again after a couple weeks. The only reason I changed was that the old ones were 3 yrs old.

they are the exact ones that fit our system. They are hard to find but these fit perfectly.

Just what I needed. Works great.

Excellent replacements for my R/O water filter

The filters were easy to replace and the water tastes great. However, it would have been very helpful if the supplier provided a set of instructions, particularly the sterilization procedure for the RO tank. All of the sterilization procedures I could find were for systems that required sterilization of the entire system, not using sealed filters.
