Summary

Product identification

PENTEK® offers five under-sink, point-of-use systems with various contaminant reduction capabilities:

• US-1000 & US-1500 Chemical/Lead Systems: NSF certified to reduce 43 different VOCs, lead, cysts, mercury, asbestos, and chlorine taste & odor.
  • The US-1500 features an electronic monitor for filter replacement.
  • The US-1000 features MTBE reduction.
• AS-301E Arsenic Reduction System*: Reduces Arsenic III & V and chlorine taste & odor. Includes a mechanical meter.
• RO-3000 & RO-3500 Reverse Osmosis Systems: Offer the finest level of water filtration, filtering particles as small as 1/1000 of a micron. NSF certified to reduce salts, dissolved minerals, and bad taste & odor. Designed for chlorinated or non-chlorinated water.
  • The RO-3500 features an electronic water quality monitor to indicate when to change the RO membrane.

*AS-301E is not performance tested or certified by NSF.
