This is the replacement cartridge for the H300-HSD Drinking Water System.  HSD stands for high silt density - this is a fancy way of saying 'a lot of dirt'. 

If you are finding that you get short life from our traditional H300 cartridge, this HSD cartridge will give you longer life without compromising on quality.

This water filter reduces the following contaminants:

  • Lead
  • Asbestos fibers
  • Parasitic cysts such as Giardia and Cryptosporidium
  • Chlorine taste and odor
  • Dirt and cloudiness
  • Mold and algae
  • Oxidized iron, manganese and sulfides
  • Particles down to 1/50,000th of an inch

How often should I change the filter?:

We recommend changing this filter 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.

Filter life depends on three factors, and these three are unique to you:

  1. How often you use the filter
  2. How dirty your water is
  3. What kind of water pressure you have

All Everpure residential systems and cartridges include a Time strip filter monitor to remind you when 11 months have passed. This is based on the recommendations by Everpure to change the filter on an annual basis.  Remember to buy only genuine Everpure replacement cartridges to maintain your warranty.

The real thing

I’d had disappointing results with replacement filters I’d bought online and feared I’d received inferior or counterfeit filters. But I decided to give one more chance by seeking a dedicated seller and bought from This one seems like the real deal, and has performed as I’d expect - with clean fresh water. The purchase experience was also excellent, with frequent communication on the order status. My credit card charged an international transaction fee, which was a surprise, but that was the only negative, and was a small fee, so not significant. I would buy from efilters again.


Thank you for trusting us to deliver; we really appreciate the opportunity!

Reliable Vendor to buy Water filters from

All instructions to replace the filter was provided clearly by EFilters, in addition to the filter manufacturer. This is the 2nd year I am buying from EFilters and am happy with the order and shipping process. As far as the filter itself, I can say that aftermarket filter versions do not necessarily do a good job - I can only observe it in how low the water flow is right after installation. I have since decided to buy Pentair / Everpure original filters. They work as expected.


Thank you for your repeat business!

Excellent Resource!

I installed my Everpure water filtration system almost 8 years ago. It's an efficient system that delivers good-tasting water without wasting any in the process, and I love it. If there's a downside, it's that replacement filters aren't always immediately available and can be pricey. Searching for one, I stumbled onto Efilters and liked the web site--it's thoughtful, clear, and professional; it suggests that education and support are strong in the company's mission. Efilters made it easy to order; it was simple to link to what I was looking for and the product pictured was exactly what I needed--at the very best price, with no added shipping charge. It arrived well-packaged within just a few days. Efliters can be trusted, and I will be ordering for all my home water filtration needs from this company from now on.


Hi , hope you have been doing well. Thank you so much for this lovely and sweet review about our company. It makes us thrilled to know you had the best experience shopping with us, we look forward to hearing from you again :)
