FAQ

Q: How often should each H-300-NXT cartridge in this 6-pack be replaced?

A: Each cartridge should be replaced once it reaches its 300-gallon capacity, when water flow noticeably slows, or at minimum once per year—whichever comes first. With 6 cartridges included, this bundle covers up to 6 years of annual replacements for a single-system household.

Q: Are the cartridges in the EV927446 6-pack identical to the single-pack EV927441?

A: Yes. The EV927446 contains the same H-300-NXT replacement cartridge as the EV927441 single-pack—same filtration technology, same capacity, and same NSF certifications. The 6-pack format simply offers a more cost-effective option for long-term supply.

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

A: Yes. The H-300-NXT requires a dedicated drinking water faucet separate from your main tap. It installs vertically under the sink with the cartridge hanging down, and requires 2½ inches of clear space below the unit for easy cartridge changes.

Features & Benefits:

• NSF/ANSI Standard 401 Certified for Emerging Contaminants: The EV927446 cartridges are among the first of their kind certified to reduce pharmaceuticals, over-the-counter medications, herbicides, pesticides, and industrial chemicals like BPA—addressing contaminants that most standard filters do not cover.
• 6-Pack Value for Long-Term Peace of Mind: With six cartridges included, the EV927446 ensures uninterrupted, year-round filtration for up to 6 years of annual replacements, eliminating the hassle of frequent reordering and reducing per-cartridge cost.
• Exclusive Dual-Stage Micro-Pure Filtration: Combining Micro-Pure precoat technology with a pleated filter membrane 30% larger than the H-300, this dual-stage design ensures consistent 0.5-micron particle reduction and superior dirt-holding capacity throughout each cartridge's full lifespan.
• Commercial-Grade Durability with KDF Scale Inhibition: The signature metal canister resists splitting and bursting under pressure, while built-in KDF media inhibits lime and scale buildup in water-using appliances—helping extend both filter and appliance life over time.
