NSA - National Safety Associates 
100SX Under-Sink Water Filter 

The 100SX manufactured by NSA was the last design National Safety Associates came out with. The unit was comprised of GAC (granular activated carbon) and Silver impregnated media. The GAC & Silver impregnated media removed chemicals and organics such as chlorine, pesticides, detergents, bad taste, also while reducing sediment, discoloration and inhibiting bacteria growth. This unit was discontinued effective 1/1/2008 . It is highly recommended if you own one of these units to uninstall it and purchase the newly upgraded unit called the 100US sold by WM Filter. While the NSA 100SX water filter was an excellent design and water filter WM Filter has taken what NSA created and improved upon the design by replacing the silver impregnated media with KDF. KDF Media is used to replace silver-impregnated systems. Silver is toxic, KDF Process Media are not. Silver must be registered with the EPA as a toxic pesticide, KDF Process Media does not. 

Benefits of KDF Process Media

  • Significantly extend the life of granular activated carbon
  • Are recyclable
  • Effectively removes chlorine, heavy metals and control microorganisms
  • Outperforms silver-impregnated carbons
  • Requires no EPA registration, thus less red tape

By keeping the same filtration concept as the NSA 100SX under-sink water filter and replacing the media with KDF the unit is now much more effective in removing chemicals as well as being much safer. The unit can easily be changed out for the newer 100US. As of 2007 Water Marque has taken over ALL Air and WATER replacements for NSA.
