Our NSA 50C units are best known for their ability to condition your drinking water by removing Chlorine, Taste, Color & Odor, and are designed to mount directly on kitchen faucet. Included, are the manual and all hardware necessary for mounting. Capable of cleaning approximately 5000 gallons of water and removing hundreds of contaminants, the 50C unit installs in minutes without tools, and fits any faucet.  Adapters are included with this is compact, light and economical unit.

Capable of removing the 20,000 plus known industrial compounds that are being produced in America, along with dust, rust, viruses, bacteria and germs, plus a decaying water infrastructure, you’ll want to protect your family by having our NSA 50C Countertop unit, or one of our other NSA bacteriostatic units.

Why Granular Activated Carbon (GAC)?

Problems arise from chemical compounds that include chlorinated hydrocarbons in various pesticides, herbicides, and industrial solvents. Misuse and improper disposal of these materials has allowed drinking water supplies to become contaminated. Often, water users frequently do not learn of such contamination until after it has already occurred according to a report prepared for the council on Environmental Quality and distributed by the US Department of Commerce.

  1. Granular Activated Carbon (GAC) has been proven to be an effective, economical media for the removal of such contaminants from drinking water.
  2. GAC has a unique ability to both absorb and adsorb chlorine from water. Activated carbon granules have a great of surface area because of their irregular shape.
  3. Compounds which are products of a reaction between chlorine and organic substances present in drinking water are also removed by activated carbon. GAC is a preferred method for protection of drinking water from trihalomethanes (THM’s) and has been proven very effective in their removal.

Because of this combined capability of GAC to remove chlorine and improve aesthetic attributes (taste, odor, appearance) of drinking water at a reasonable cost, NSA chose to use GAC in NSA Bacteriostatic Water Filters.

Why Bacteriostatic?

The following information is intended to clarify the difference between home drinking water filters utilizing only Granular Activated Carbon (GAC) and home drinking water filters which use both GAC and silver-impregnated GAC.

NSA Bacteriostatic Water Treatment System to Common Water Filters

The following comparison tests between the NSA Bacteriostatic Water Treatment System and a common water filter were conducted to determine the system’s effectiveness in inhibiting bacteria growth within the unit. The NSA unit was also independently tested to prove compliance with US Environmental Protection Agency requirements.

(After passing 2,300 gallons
of water had passed
through the unit)


Test # 2
(After passing 2,900 gallons

*These amounts are considered negligible.

This chart demonstrates that the non-NSA filter units actually stored and incubated bacteria within those units, to far beyond the initial introduction of contaminate to their systems, while the NSA units easily reduced and destroyed to negligible amounts even larger contaminate quantities introduced into their systems.
