Under-Sink Drinking Water Filtration System with Dedicated Faucet - EZ

In this review of the Culligan US 1 EZ-Change Under-Sink Drinking Water Filtration System, the bottom line is simple: it is a practical choice for households that want noticeably better tasting and clearer water at a dedicated faucet without a complicated installation. The system's twist-on, twist-off cartridge design and included tubing and hardware make swaps quick and mostly mess-free, and the RC-EZ-1 cartridge is rated to treat up to 3,000 gallons or about 12 months of typical use. For kitchens that need an economical, under-sink filter to improve taste and reduce particulates, this unit delivers solid value.

Key Features

• Dedicated faucet: Supplies filtered water from its own chrome faucet so drinking and cooking water stays separate from the unfiltered sink supply.
• EZ-Change cartridge: The twist-on, twist-off filter cartridge makes replacements fast and avoids the need for tools or buckets.
• Filter performance: The included RC-EZ-1 cartridge reduces Class III particulates and chlorine taste and odor for cleaner, better-tasting water.
• Included installation kit: Tubing, fittings and mounting hardware are supplied to complete an under-sink installation without extra parts.
• Replacement compatibility: Accepts RC-EZ-1, RC-EZ-3, and RC-EZ-4 replacement cartridges for different filtration needs or budgets.
• Certified reduction: The filter has been tested to NSF/ANSI Standard 42 for aesthetic reduction of chlorine taste and odor and nominal particulate removal.

Who It's For

This system is well suited to renters, homeowners and small families who want a dedicated source of drinking water without altering existing plumbing. It is also a good match for kitchens where bottled water is being used mainly because tap water taste is poor; the unit noticeably improves flavor and odor at a much lower ongoing cost than bottled water.

Those who need whole-house treatment, heavy contaminant removal (for example lead, VOCs, or microbiological contaminants), or a system with an integrated countertop faucet should look elsewhere. Also consider a different product if you have very high flow demands or want a multi-stage under-sink system with reverse osmosis.

Pros & Cons

• Replacement cartridges are available in different models to match filtration needs and budget.
