REPLACE THAT NSA 100S
WATER FILTER (TIME BOMB) NOW!
If you haven't already seen our bulletin on it, click HERE
to read why and how current NSA 100S users are at risk.

Same size & flow pattern as the NSA 100S
EXCEPT...

  • It doesn't explode! (is that really too much to ask?)
  • It costs less ($195 vs $219)
  • It's more efficient at contaminants removal
    (GAC + KDF vs all GAC)
  • It lasts longer (25,000 gal. vs 12,000 gal.)

  It's the H2O-US413 -- In-line Undersink Water Filter
Designed expressly to replace the discontinued National Safety Associates
(NSA) 100S or the NSA 3000HM filter. NOTE! -- As a REPLACEMENT filter, it is presumed that the inlet and outlet connector lines are in place and do not need to be replaced. This filter is shipped with no accessory hardware or connector lines -- only the filter to replace an existing installed filter.

  • 5 stage filtration and purification system
  • Hooks up to existing faucet and water feed connector lines
  • Bacteriostatic media: Prevents bacteria growth
  • Improves taste, eliminates odors, removes color
  • Removes hundreds of contaminants
  • Expected Service Life, a whopping: 25,000 gal.
  • Manufacturer's prorated warranty 
 

-- 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 $10 more you get an additional 10,000 gallons of flow-thru service life. [$10 divided by 10,000 gallons = roughly $0.001 per gallon.] Yep. That's a TENTH of a penny 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.

"I got up this morning and the kitchen floor was covered in water. How soon does the replacement get here? Thanks, wished I had seen this warning sooner." -- Dan R., Texas, USA (Apr. 2006)

"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)
