      NSF Certification: This product 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.

      Please note: this cartridge fits into the QL1, QL2, QL3 and QC4 heads. If you have a ProSeries head, please refer to the ProSeries 1500 - 2500 - 3500 cartridges.

        Buying experience was great, product was terrible

        Absolutely nothing wrong with the buying experience. Website is good, shipping is fast, I wish more online retailers were like that. However the H-300 filter is garbage, quality has really gone downhill. That is 3 filters in a row now that I've had serious issues with. I cannot imagine eFilters.ca is terribly happy either, they probably return many to the manufacturer. I've had carbon flecks that never go away, and now a suspected o-ring that doesn't seal properly so it leaks. That's 3 for 3 in a row for me that have been bad. Will be looking for an off-brand from now on.



        Hi Jonathan, hope you have been doing great. We really appreciate your feedback. We are so sorry to hear the issues you have been having with the H300. We promise we want you to be 100% satisfied with our product. We are looking forward to helping you find a solution to the issues you are having with the product.
