-- If you don't need to match up water lines exactly like the NSA 100S was installed, there's an even better deal. It's the Model US4-R Undersink filter replacement. It's about three inches taller than the NSA 100S, but it's rated for an even more economical 35,000 gallons. Here's the math. For just $6 more you get an additional 10,000 gallons of flow-thru service life. [$6 divided by 10,000 gallons = roughly $0.0006/gallon. Less than a tenth of a cent per additional gallon.]

IMPORTANT: This filter uses the opposite flow pattern than the NSA 100S. The US4 INLET connector is at the base and the OUTLET connector is at the top of the filter, so you'll need to swap ends with the two water lines from the way the NSA filter is connected.
Click HERE to check out the US4-R for only $175.00.

"For your information, when I read on the web site about NSA undercounter filters exploding, I was a little skeptical but ordered your H2O replacement filter since it needed no repiping. The next day, while we were in the kitchen, the old NSA filter exploded, but we were right there to shut the water off since we were informed what it might be. Thank you for your warning." -- Fred F., Florida, USA (September, 2005)
