Quality Water for your cooking & drinking needs

The H300-NXT cartridge is the replacement water filter for the H300-NXT drinking water system.  This cartridge can also be used in place of any existing Everpure replacement cartridge, such as the H300, H54 or H104.  Because of the universal design of the Everpure Head, you can try different cartridges to suit your needs.

This cartridge is an upgrade from our best selling H300 because of these enhanced features:

  • NSF certified to reduce pharmaceuticals, BPA and other emerging contaminants
  • 50% greater dirt holding capacity than the H-300 cartridge
  • 30% larger filter membrane than the H-300 cartridge

The H300-NXT has been tested and certified by the National Sanitation Foundation (NSF). This means that the claims that Everpure makes regarding performance and capacity have been tested and certified to be true.  This provides you with peace of mind that what you are buying will deliver on its promise of quality.

We recommend changing the filter on an annual basis or when the flow rate becomes inconveniently slow. Our water quality is changing all the time.  Even if you have your water tested, that is just a snapshot on that particular day, so don't be surprised if the frequency of cartridge change fluctuates from one year to the next; this is normal.   

What matters most is knowing that regardless of the water quality going into the water filter, the quality coming out will always be the same.  This is the promise that Everpure delivers on and that is why it is so important to only buy a water filter that is third party tested and certified by NSF. Without NSF, the manufacturer can make whatever claims they want. The two important standards are #42 and #53. Read more on this important certification.

        Fast shipping, quality product

        Efilters has the best prices on these filters. It has gone up in price like everything these days but they helped by offering a 5% welcome discount. I like that this also filters some medical waste which is in all water now.



        Thank you Karen. You are absolutely correct. The NXT is NSF certified to reduce pharmaceuticals, BPA and other emerging contaminants!

        Works as it Should

        The filters work great to remove the bad stuff from the water. The only issue I usually have is that it drips when you first install it and I have to reinstall the filter a couple of times then monitor over the next couple of days to be sure it has stopped.



        Morning John and thank you for your review. There is a black o-ring on the tip of the cartridge that may just need a little moisture to expand it ever so slightly. A wee bit of petroleum jelly will also help with this.
