Pre filter

We use this in its little pill looking form as a pre filter for our countertop RO filter system.

The filter fills and clogs in a rough environment (probably our building doing maintenance) and this filter has probably saved our countertop RO system an early retirement or two.(we've been using these products for a decade I think🤔 )

Great Filter

I found this filter as a replacement for a similar filter made by Filtrex, which is nearly impossible to find now. It was a perfect replacement and is working very well in my RO system. Crystal Quest is the only other manufacturer that I have found that makes a cartridge in this size that is able to filter below 0.2 microns.

Ultrafiltration

My home in a rural area has a 30 ft deep water well, which produces good water. Just to be safe I have been using whole house ultrafiltration membrane filters from Crystal Quest for the past 10 years. I test the water twice a year, always with good results. Also use a multistage filter on the kitchen sink. I initially consulted with one of their engineers about the filters and got good advice. I will continue purchasing filters from them, even though I am not too fond of the recent price increase. We all got to make a living.
