RKIN Water Systems

RKIN was started for one reason: getting truly clean water and air at home was expensive, unappealing, and a hassle to install or maintain. As renters and homeowners, we were stuck between wasteful bottled water, complex plumbing, and clunky purifiers that didn’t deliver.

So we built zero‑installation reverse osmosis systems that look great on your counter and deliver pure, amazing‑tasting water from day one - no tools, no holes, no hassle. Then we brought the same “pure life, simplified” promise to air with HEPA 14 purification plus UV, activated carbon, and ion technology to remove allergens, pet dander, odors, and wildfire smoke - quiet Sleep Mode at night, Auto Mode with real‑time air‑quality readouts and app control for peace of mind.

For homeowners who want protection at every tap, we engineered whole‑house systems - water softeners and filters that tackle hardness, iron, sulfur, and chlorine to protect plumbing, extend appliance life, and upgrade every shower and sip. Through it all, our promise never changed: simplify purity. We obsess over reliability, design for everyday living, and make upkeep easy, backed by fast, expert support and strong warranties - so you get healthier water, cleaner air, less plastic, and a home that just works.
