The Everpure H300 Cartridge for the H300 Drinking Water System

This water filter reduces the following contaminants:

  • Lead
  • Asbestos fibers
  • Cysts such as Giardia lamblia, Entamoeba histolytica and Cryptosporidium
  • Volatile Organic Chemicals (VOCs), including THMs
  • Chlorine taste and odor
  • Dirt and cloudiness
  • Mold and algae
  • Oxidized iron, manganese and sulfides

Frequency of filter change:

When we are asked how long will a filter last, we have an quirky answer: 'How long is a piece of string'? We don't mean to be cheeky but it's a fair response (really)...because the reality is we don't know. The life of a filter depends on your incoming water pressure, how much you use it and how dirty your water is.  These three variables are unique to you.

Everpure recommends changing a filter once a year, we like to suggest that you change it when the flow rate slows down to the point of being inconvenient. It's important to remember that 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. On average, the H300 lasts approx. one year so please consider that as a benchmark.

Good to the last drop!:

As the filter removes more and more particles of dirt and stuff, the flow starts to slow down, but the quality of the water coming out of the filter is as good as the first drop. 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. Did you know that this filter removes particles down to 1/50,000th of an inch?  That's the same as 1/2 micron.  The human eye can only see down to 40 microns. 

NSF Certification:

This drinking water system is third party tested and certified by the National Sanitation Foundation (NSF) for Std. 42 & 53. The nitty gritty details can be found on the product spec sheet found below. Standard 53 is the most important as it certifies for the removal of parasitic cysts, such as Cryptosporidium, and Lead.  Read more about NSF.

            Nice Company

            It was very nice of the company to notice I had not taken advantage of 50% coupon and credited my card for the difference. An $80 savings!



            We aim to please!

            Everpure H-300 Drinking Water Cartridge

            I have not yet installed the new cartridge. I purchased the one I'm currently using from your firm some time ago. The product is very satisfactory. Delivery this time was very prompt.



            Great to hear during these challenging times. We appreciate your business!

            I have always felt the H-300 filter has worked well for me. I want to take a moment to say that ordering from Efilters has also been a pleasant experience. The filters arrive in a timely manner and in good condition! The boxes are always sealed and new. Years ago I receved a filter from another company and I got it in an opened box! So glad to find a trustworthy company to do business with that also carries top rated items.



            Wow, this is an amazing review. Thank you so so much!
