The LARQ Under Sink Water Filter system delivers instantly filtered cold water straight from your kitchen faucet (or any faucet for that matter).

Unlike reverse osmosis systems, there's no wastewater, no electricity, and no bulky storage tank. The compact design (14.5" × 3.8" — about the size of a 2-liter soda bottle) fits under most standard sinks.

Installs in about 15 minutes with no plumber, minimal tools, and no permanent modifications — renter-friendly.

Independently tested to NSF/ANSI 53, 42, and 401 standards, it removes lead, PFAS (PFOA/PFOS), microplastics, pharmaceuticals, chlorine, VOCs, and 60+ other contaminants — while preserving the calcium and magnesium that make water taste great.

One filter lasts up to 6 months (1,453 gallons), and replacements take seconds: pull, push, done.
