The Everpure EV9270-72 H-300 replacement cartridge has a rated capacity of 300 gallons or a service life of 6 months, whichever comes first. This residential-grade filter is ideal for household drinking water systems and should be replaced on schedule to maintain optimal flow rate (0.5 GPM) and consistent filtration performance in your Everpure H-300 drinking water system.

The Everpure EV9270-72 H-300 features a 0.5 micron nominal filtration rating using Everpure's proprietary Micro-Pure II media with precoat technology. It reduces chlorine taste and odor, dirt, cloudiness, and particulates down to 0.5 microns in size, including cysts such as Cryptosporidium and Giardia. The tightly compacted carbon block also reduces off-tastes while allowing healthy minerals to pass through for great-tasting water.

Yes, the Everpure H-300 cartridge is tested and certified by NSF International against NSF/ANSI Standard 42 for aesthetic effects (chlorine taste and odor, particulate reduction Class I) and NSF/ANSI Standard 53 for health effects, including cyst reduction (Cryptosporidium and Giardia) and asbestos reduction. This certification verifies Everpure's performance claims for the H-300 drinking water system.

The EV9270-72 is a direct OEM replacement cartridge specifically designed for the Everpure H-300 drinking water filtration system. It features Everpure's signature bayonet-style mount for a quick twist-on/twist-off installation—no tools required and no need to shut off the water supply at the head. Do not substitute with non-Everpure cartridges, as the proprietary head design requires genuine Everpure cartridges for proper sealing and performance.

Installation is simple with Everpure's QL (Quick-Lock) bayonet system: remove the old cartridge by rotating it 1/4 turn to the left, insert the new EV9270-72, and rotate 1/4 turn to the right until it locks. Flush the new cartridge for approximately 5 minutes or 3 gallons before use to remove carbon fines and activate the Micro-Pure II media. Mark your calendar to replace the cartridge every 6 months or at 300 gallons to maintain certified performance.
