- BRS 4 Stage RO Only Replacement Filter Kit
This kit works with the BRS 4 Stage RO Only System. Our filter kits feature some of the most widely used and trusted brands in the world including GE, KX Technologies and Pentek. The 10” filter size is the industry standard and will fit our systems as well as virtually every brand of RO system that uses similar looking carbon blocks. Our filter elements are NSF Certified or WQA Gold Seal Certified and Manufactured using FDA-compliant materials.
We recommend changing sediment filters when they become visually dirty or there is a noticeable drop in pressure. Change carbon blocks every 6-12 months depending on use. This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up.

Perfect replacement By Imaputtzz on 2/16/2015Imaputtzz would recommend this product to a friendPerfect replacement for my aging RO/DI unit. These filters fit perfectly into my cheap RO/DI purchased elsewhere and with the addition of the DI Resin I have 0 TDS finally! I plan to purchase a new RO/DI unit in the near future, but until I can afford that These work perfectly
How do you know when it’s time to change these?
The sediment filter can be changed when there is a loss of operating pressure through the unit or when visibly dirty. The carbon block can be changed when the waste water line tests positive for cholorine (using testing strips). Finally, you'll want to change the DI resin with it has visibly changed color to a light brown from bottom to top.
