    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?

    Great H2O Filters / Great Company!

    I have been buying my under sink Everpure replacement filters here now for about past 5 or more years! My last order was for two as they sent me a 50% off special which was amazing! Prices are always the best and shipping is fast and free too! Amazing customer service too. With the Everpure system our household has eliminated about 98% of plastic water bottles used - the water from our filter tap tastes as good or better than the best bottled water and the filter also supplies our ice maker in the fridge!


    How do we thank you enough for such a kind review? We appreciate this very much!

    Excellent filter

    I replaced a regular H-300 with this H-300-NXT. The waterflow is much faster even then the H-300 when it was new. Supposedly the filtration is better, though I cannot tell. The water tastes good, just like before.


    Thank you Ke for your review. You are correct; the NXT is the upgraded version and provides additional features to the H300.
