About This
- ✅ 【NSF Certified & True 5 Stage Reverse Osmosis Purification】 Trust starts with certification. The Kneysan KN-RO-100 is NSF Certified, meeting strict standards for material safety and structural integrity. This under sink reverse osmosis water filter employs a genuine 5 stage purification process—including sediment, carbon blocks, and a high rejection RO membrane—designed to effectively reduce TDS (Total Dissolved Solids) and a wide range of other impurities. It’s a complete water filter system that delivers noticeably cleaner, fresher water for your entire household.
- ✅ 【Innovative Dual Outlet Design – Two Types of Filtered Water from One System】 Why waste expensive RO water on tasks that don’t need it? Our exclusive dual outlet feature gives you the best of both worlds. One line delivers highly purified reverse osmosis water for drinking, cooking, baby formula, and anything you want the highest quality water for. The second line provides carbon filtered water—perfect for washing fruits, vegetables, and dishes—saving precious filter life and reducing wastewater. It’s a smarter reverse osmosis system that maximizes value without compromising performance.
- ✅ 【Massive 3.2 Gallon Storage Tank – Pure Water Always on Demand】 Never wait for clean water again. The integrated 3.2 gallon (approx. 12 liter) pressurized storage tank ensures a generous, ready to use supply of purified water is always available at your dedicated faucet. Whether you’re filling large pots, making coffee, or hydrating after a workout, this water purifier delivers strong, consistent flow—outperforming any countertop water filter pitcher or slow water distiller.
- ✅ 【Designed for Every Member of Your Family】 Water quality matters at every stage of life. From expectant mothers and growing children to busy professionals and valued seniors, the KN-RO-100 is engineered with everyone in mind. By effectively reducing dissolved solids, this ro water filtration system provides an extra layer of assurance for your household daily drinking water. It’s the simple, permanent upgrade for a healthier home.
- ✅ 【Compact Under Sink Design – Out of Sight, Always Ready】 Enjoy professional grade water filtration without sacrificing counter space. This under sink water filter system installs neatly out of view, preserving your kitchen’s aesthetic while working silently in the background. It’s a permanent, low maintenance alternative to temporary solutions like zero water filter pitchers or bulky countertop units. Clean water has never been this effortless.
