FAQ

Q: How often should the EV927441 cartridge be replaced?

A: The cartridge should be replaced once it reaches its 300-gallon capacity, when water flow noticeably slows down, or at minimum once per year—whichever comes first. Annual replacement ensures the highest level of filtration performance.

Q: What makes the H-300-NXT different from the standard H-300?

A: The H-300-NXT features a pleated filter membrane that is 30% larger than the H-300, providing better dirt-holding capacity and longer filter life. It also adds NSF/ANSI Standard 401 certification, which covers the reduction of emerging contaminants such as pharmaceuticals, BPA, and other incidental compounds not addressed by the standard H-300.

Q: Does the H-300-NXT system require a separate dedicated faucet?

A: Yes. Unlike the EF-6000 full-flow system, the H-300-NXT requires a separate dedicated drinking water faucet for dispensing. It should be installed vertically under the sink with the cartridge hanging down, and needs 2½ inches of clear space below the unit for cartridge changes.

Features & Benefits:

• NSF/ANSI Standard 401 Certified for Emerging Contaminants: The EV927441 is among the first residential water filter cartridges certified to reduce pharmaceuticals, over-the-counter medications, herbicides, pesticides, and industrial chemicals like BPA—providing an advanced layer of protection beyond standard filtration.
• Exclusive Dual-Stage Micro-Pure Filtration: Combining Micro-Pure precoat technology with a unique pleated filter membrane, this dual-stage design delivers a 30% larger filtration surface area compared to the H-300, ensuring consistent 0.5-micron particle reduction throughout the entire cartridge life.
• Commercial-Grade Durability at Home: The signature metal canister construction protects the system from splitting or bursting under pressure, while KDF media inhibits lime and scale buildup in water-using appliances—extending both cartridge and appliance life.
• Retains Beneficial Minerals for Great Taste: Unlike reverse osmosis systems, the H-300-NXT's filtration process removes harmful contaminants while preserving naturally occurring minerals, delivering clean, crisp-tasting water without stripping water of its natural character.
