The Resin filter cartridge reduces hardness and scale deposits in water, leaving all the benefits of soft, gentle, clear water. Convenient, compact design means that softened water can be provided at point-of-use.
Hard Water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), and Iron (Fe). Removal of these minerals is accomplished by softening the water through an ion exchange process using water softener resin.
Our resin cartridge contains a 10” column, filled with polymer resin beads. The small beads create a large surface area in contact with water as it flows past.
The resin is made of polymer that binds positively charged ions. Initially the polymer surface is saturated with sodium ions, meaning that there are sodium ions available on the surface of the ion exchange resin. These ions are weaker than calcium & magnesium ions. The polymer is designed specifically to bind more strongly to the calcium & magnesium ions, than to the sodium ions.
When the hard water flows past the 1000’s of resin polymer beads, the calcium & magnesium ions will bind to the polymer, displacing the sodium ions into the water. These sodium ions are removed by the next cartridge.
Fits all standard 20″ big blue filter housing with easy installation/replacement.

I have very hard water in my area and noticed a difference almost instantly, and my animals are drinking more water now which is great to see. Mavis and Rob have been fantastic from the start, being very responsive and eager to answer any questions.

Rob and Mavis have been great service to me and my new home (which I had to suffer and wait for ~4years to get house completed). They are excellent in providing advice that are practical and pragmatic. Please, I cannot promote them further. have a 3-stage full house water filter system, and I love it. and I agree with them, “It is a MUST”.

We installed the whole house water system last year and it has helped us remove water contaminants like rust. It has also saved some of our house hold appliances like kettle that always had calcium.

We have had our filtration system for approximately 2 years, 100% happy with the system we haven’t had to bye bottled water since as the tap water is so good after going through the 3 stage filtration system. Mavis & Rob are the local distributors very friendly & helpful and are a local family business too.
