Usability
The CRO1000 is where iSpring stops making appliances and starts making equipment: 20-inch cartridges, a stainless membrane housing, dual gauges and a rolling frame, at 80 to 130 psi working pressure. For a restaurant or coffee shop it is the sensible step below the $3,779 CRO2000, delivering half the output for well under half the money. It needs a plumber and floor space, and there is no NSF/ANSI listing.
- 1,000 GPD at 0.7 GPM on genuinely commercial hardware
- 20-inch cartridges and a stainless steel membrane housing
- Built-in inlet and outlet pressure gauges for real diagnostics

The iSpring CRO1000 is a true commercial-grade tankless reverse osmosis system rated at 1,000 gallons per day with 0.7 GPM output. It runs one 20-inch PP sediment filter in a clear housing, two 20-inch carbon block filters, and a 1,000 GPD membrane in a stainless steel housing, all mounted on a freestanding metal frame on wheels with locking brakes.
Working pressure is 80 to 130 psi, higher than any residential system in the range, and built-in inlet and outlet gauges make pressure monitoring part of routine checks rather than guesswork. The clear first-stage housing means sediment loading is visible without opening anything.
It connects to whatever you need it to: dispensers, drinking faucets, ice makers, refrigerators, espresso machines, hydroponics. Service intervals are 3 to 6 months on stage one, 6 to 12 months on stages two and three, and 2 to 3 years on the membrane. iSpring lists no NSF/ANSI certification for the CRO1000.
