PSE-300 - Replacement Cartridge for Everpure H-104 / Everpure H-300

High Performance Under Sink Water Filtration System – 0.5 micron filtration reduces and/or removes chlorine, lead, VOCs, algae, and more. 2,200 more gallon capacity than the Everpure H-300!

To ensure you get the best value, our water experts created the PSE-300FS to provide you a competitively priced filter system for longer filter life than the Everpure H-300 system. It has more filter media and a 2,500 gallon capacity; the Everpure H-300 is only 300 gallons. The larger gallon capacity saves you the time, effort, and money of changing water filters as often.

The filter cartridge on this system is quick, easy, and sanitary to change. Just like the Everpure H-300, the 0.5 micron PSE-300FS reduces lead, volatile organic chemicals (VOCs), cryptosporidium, asbestos fibers, dirt, chloramine, chlorine taste and odor, mold and algae, and more. This water filter system delivers exceptional filtration for home, office, and commercial applications.

PSE-300FS Water Filter System Features and Benefits:

  • Complete water filter system including head, connections, and cartridge (PSE-300); option for drinking water faucet
