Happybuy Reverse Osmosis System, 400 GPD 8-Stage Compact Under Sink Water Filter. NSF Certified, 2:1 Pure to Drain Ratio. Effectively Reduces TDS for Clean Drinking Water

Compact Tankless System: Our tankless reverse osmosis system is compact, measuring 15.63 x 5.39 x 13.66 in (397 x 137 x 347 mm). It saves 75% of under-sink space and avoids water contamination. With a seamless design for reduced leakage and quick 30-minute installation, it's a quiet and efficient choice for home or restaurant kitchens.

Keep Filters Working Longer: Our reverse osmosis system offers advanced filtration through twist-in water flow and automatic flushing. This reduces sediment buildup and extends the durability of filters. RO filters last for up to 2 years, and PCF filters for 1 year, reducing the need for frequent changes.

Efficient 8-stage Filtration: Our under-sink tankless RO system combines the RO filter with a PPC composite filter for 8-stage deep filtration, effectively improving water quality. The Sri Lankan coconut shell carbon enhances the taste. Please note a slight delay between faucet activation and water flow in tankless RO systems.

2:1 Pure to Drain: Our under-sink reverse osmosis system, with a 400 GPD capacity and 2:1 pure-to-waste water ratio, optimizes water use, conserving 800% more water. The reliable 304 stainless steel faucet fits holes sized 1/4" inner and 11/4" outer.

Hassle-free Maintenance: You'll receive instant reminders when it's time to replace the filters. Changing them is easy with a twist-and-pull design, without having to move the machine. Our reverse osmosis water filter under sink is designed with advanced leak, pump, and temperature protections for reliable and safe performance.
