Watts Premier Inline Water Filter – 20,000 Gallons with 1/4-inch Brass Connectors

Overview

Meet the Watts Premier Inline Water Filter, designed to sit inline with 1/4-inch lines and serve a range of appliances—from refrigerators with ice makers to coffee brewers, water coolers, fountains, and even RVs and campers. With a certified capacity of 20,000 gallons (up to about five years under typical use), this high-capacity inline filter aims to help keep your water tasting cleaner and your devices running smoothly.

What it does

Engineered with KDF technology, the filter uses a copper-zinc media to reduce chemicals like chlorine that can create off-tastes and odors in your water. The result can be crisper water at the point of use, whether you’re filling a glass or brewing a pot of coffee. The system is NSF-certified for reducing chlorine taste and odor, and California-certified for the same benefit, plus scale reduction and improved clarity. The media is described as bacteriostatic to help extend filtration life in between changes, though maintenance is still important.
