The IntelliClear® 800 is a premium, tankless reverse osmosis drinking-water system built for homes and light-commercial sites that demand the purest water at high flow. Tested and certified to NSF/ANSI 58 (TDS reduction) and NSF/ANSI 372 (lead-free), it delivers up to 800 gallons per day of on-demand purified water.

Why customers choose IntelliClear

  • 7-stage precision filtration removing contaminants down to 0.0001 micron
  • Tankless design — always-fresh water with no storage tank to recontaminate; ~0.53 gal/min fills an 8 oz glass in about 7 seconds
  • 2:1 low drain ratio — only 1 cup of drain water for every 2 cups purified, up to 6× more efficient than traditional RO
  • Smart faucet with real-time TDS display, filter-life reminders and an IPX7-rated LED
  • Auto RO flush self-maintains the membrane for longer filter life
  • Lead-free & leak-free — all water-contact parts are NSF/ANSI 372 lead-free
  • DIY-friendly, space-saving — compact under-sink footprint, simple 3-step filter changes, no need to shut off the water
