Usability
The RO600-BN is the value pick of iSpring's tankless range: it carries the same 2.5:1 pure-to-drain ratio as the RO800G for eighty dollars less, and beats the pricier RO500 line on efficiency outright. You give up output, dropping from 800 to 600 GPD, and you give up the NSF listing that the RO500 family carries. If certification is not your deciding factor, this is the most water you get per dollar.
- 2.5:1 pure-to-drain ratio, better than the more expensive RO500 line
- Cheapest tankless system iSpring sells at $448.99
- 600 GPD with a built-in booster pump handles low supply pressure
- Only two cartridge types to track, FCF600 and MRO600
- Filter-life indicators warn before a cartridge expires
- Automatic self-clean runs after 24 hours of non-use
- Twist-and-lock filters change without shutting off the water
- No published NSF/ANSI certification listing, unlike the RO500 family
- 0.4 GPM flow is slower than the RO800G despite the same drain ratio
- No remineralization stage, so the water tastes flat
- Requires an under-sink electrical outlet
- Municipal water only; well water needs pre-treatment
- Warranty is 1 year and requires product registration
The iSpring RO600-BN is a tankless reverse osmosis system rated at 600 gallons per day, sitting between the 500 GPD RO500 line and the 800 GPD RO800G. A built-in booster pump feeds an FCF600 composite pre-filter and a 600 GPD MRO600 membrane, filling an 8 oz cup in under 10 seconds at up to 0.4 GPM.
It runs a 2.5:1 pure-to-drain ratio, matching the RO800G and beating the 2:1 of the RO500 family. Filter-life indicators stay white in normal use, blink white below 10 percent remaining and turn red when replacement is due. An automatic self-clean cycle runs after 24 hours without use.
The body is BPA-free and the twist-and-lock cartridges change without shutting off the water supply. iSpring publishes no NSF/ANSI certification listing for the RO600-BN, unlike the RO500 line, so its contaminant figures are manufacturer specifications.
