For long-term storage, you can remove and wrap the filter, storing it in the refrigerator (36-41°F / 2-5°C), not the freezer.

It requires no installation—just plug it in and it's ready to serve a family of 2-5 people. The system produces about 6.8 oz/min (200ml/min) of purified water. The filtered water is automatically stored in a jug, so clean water is always ready on demand—no waiting. Please note that it dispenses water at room temperature only.

- 【Certified Safe with Real-Time TDS Display】 Your safety and peace of mind come first. This unit is certified to NSF/ANSI/CAN 372, and the filter core is also certified by SGS—ensuring material safety and high water quality. For added transparency, the control panel shows real-time TDS levels—displaying both “TDS In” (source water) and “TDS Out” (purified water)—so you can see the filtration performance at a glance.
- 【Advanced 6-Stage Filtration with Mineralization】 This system utilizes a 6-stage reverse osmosis process, enhanced by Aquaporin Inside technology. Powered by Aquaporin proteins that mimic natural water filtration, it effectively removes chlorine, lead, calcium, and reduces TDS by filtering out impurities as small as 0.0001 microns. The final stage is a remineralization layer that adds back beneficial minerals, improving the taste and profile of your water. We recommend using tap water or another clear water source. The integrated filter lasts up to 12 months.
