    Frequency of cartridge change?

    The life of a filter is dependent on three variables:

    1. How much water you use / how much you drink
    2. What the water quality is like coming into your home
    3. What the incoming water pressure is like coming into your home

    These variables are not only unique to you but they are constantly changing. Our recommendation is to keep an eye on the flow rate.  When it becomes inconveniently slow, it's time to change it. 

    All Everpure residential systems and cartridges include a Time strip filter monitor to remind you at 11 months that it's time to order a replacement  cartridge.  Remember to buy only genuine Everpure replacement cartridges to maintain your warranty.  Better yet, why not join our free lifetime warranty program?

    Fantastic filter

    I love your products. Period. I struggled for years with one of those other systems with the plastic filter housing...frigging water everywhere when I'd change them. Now, it could not be simpler. And, the water quality is better, I'm certain, and better tasting, without a doubt. Thank you for improving the whole process!


    Thank you for the Awesome review Thomas! We are thrilled to hear that you are satisfied with your purchase and experience. Your feedback is very much appreciated. Thanks again!
