Pros
  • Covers the most common under-sink RO needs at one of the lowest prices for a certified system
  • Standard 10 inch filters keep yearly upkeep low, and many brands make compatible cartridges
  • Needs no outlet, so it fits any sink cabinet with a cold water line
  • Independently certified to NSF/ANSI 58 for dissolved solids reduction
Cons
  • The storage tank takes up a large share of the cabinet
  • iSpring does not publish a drain ratio, and tank systems without a pump usually send several gallons to drain per gallon made
  • Refill slows when line pressure is below 45 psi
