Description

QMP 301 ALKA QC (1/4” Quick Connect) — Alkaline Inline Water Filter

Reverse osmosis produces exceptionally clean water—but many homeowners prefer a more balanced finish after filtration. The QMP 301 ALKA QC is an alkaline inline water filter designed to be used after your RO membrane as a post-RO polishing stage.

Installed inline on standard 1/4” tubing, this filter uses a quick-connect design to make upgrades simple—no special tools or complicated plumbing. Once installed, it helps increase pH and supports a negative ORP profile as water flows to the faucet.

Why use an alkaline inline water filter after RO?

  • Balanced finish: RO water can taste “flat” to some people; post-RO alkalinity can create a smoother drinking experience.

  • Easy upgrade: Quick-connect installation makes it a simple add-on to most RO setups.

  • Final-stage polishing: Designed to work as the last step before dispensing.
