Summary of NSF Water Filter Standards

If we had a nickel for every single time someone asked us what NSF 42, 44, 53, 55, 58, 62 and 177 meant… we’d have a huge pile of nickels and STILL not have enough money for that diamond-plated, gold-encrusted, platinum embossed drinking fountain w/ the GIANT water purification FACTORY attached to it from the other side of the wall.

NSF/ANSI Standard 42: Drinking water filtration systems that are certified to this standard remove chlorine and sediment/particles from water for the purpose of improving its look, smell and taste. The design of these filter do NOT lend themselves to the removal or reduction of health-related contaminants.

NSF/ANSI Standard 44: Water treatment systems certified to this standard typically function as cation exchange water softeners designed to reduce or eliminate water hardness (i.e. calcium and/or magnesium). Water filters designed to remove barium and radium may also certify to this standard.

water softeners

NSF/ANSI Standard 53: Water purifiers certifying to this standard have designs that remove health-related contaminants such as waterborne organisms and industrial chemicals. Cryptosporidium, giardia, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether) and trihalomethane compounds (THMs) fit into one of those categories or the other.

NSF/ANSI Standard 55: Devices rated to this standard function as point of use (POU) or point of entry (POE) ultraviolet microbiological water treatment systems. These water treatment systems feature designs which disinfect microorganisms (such as bacteria and viruses) potentially present in water.

UV Sterilizers

NSF/ANSI Standard 58: Typically one will find reverse osmosis water systems (RO) certified to this standard. Devices in this category will normally have the ability to fully remove organic contaminants, but may only partially remove inorganic compounds and heavy metals.

NSF/ANSI Standard 62: Certified to this standard one will typically find water distillers. The process of distillation removes a wider range of drinking water contaminants than all other methods of drinking water purification. Arsenic, mercury and bacteria all get eliminated through the use of water distillation systems.

shower filters

NSF/ANSI Standard 177: Water filtration units certified to this standard function as shower head filters designed to remove chlorine from water.

Useful Add-On for RO and Other Filter Systems (UV Sterilizer)

Water Testing BlogReverse Osmosis, THM, Trihalomethane, UV Sterilizer, Water Testing

While a quality reverse osmosis system DOES provide excellent protection against waterborne contaminants, including various forms of bacteria and cysts (i.e. Giardia and Cryptosporidium), use of a UV sterilizer system on water exiting a reverse osmosis system adds an extra level of protection against organics unmatched by any other readily available water purification method.

Ultraviolet Water Sterilizer Systems meet the most demanding needs of residential and commercial microorganism control — which sometimes proves difficult for traditional disinfectant methods given that microorganisms can range from bacteria and viruses to algae and protozoa. UV treatment systems for water accomplish the goal of disinfecting water faster than chlorine and without without cumbersome retention tanks filled w/ corrosive and potentially harmful chemicals.

Manufactured with axial flow reactors in 304 stainless steel for durability, the Crystal Quest Ultraviolet Water Sterilizer Systems incorporates natural ultraviolet light energy to damage the DNA of microbiological contaminants and in doing so kills them and/or renders them incapable of reproducing.

Applications for UV sterilization systems include post undersink water filters, post whole house water filters, water coolers, pre and post osmosis systems, private wells, camp grounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, laboratories, marine, pharmaceutical, dairies and many other applications.

Advantages of Crystal Quest Ultraviolet Water Sterilizer Systems include:

  • No need to add chemicals to the water which could form carcinogenic disinfection byproducts (DBP’s) like trihalomethanes (THM’s).
  • Eliminates the need to store and handle dangerous chemicals.
  • Requires only two water connections (in and out) and a power connection.
  • UV sterilization typically does not alter the taste, odor, pH or conductivity or general chemistry of the water it treats.
  • Works faster and more effectively against viruses than chlorine.
  • Systems can treat hundreds of gallons of water for each penny of operating cost.
  • Immediate treatment process eliminates need for holding tanks, long retention times, etc.
  • Units operate automatically and require almost no attention.
  • Most units require only periodic cleaning, if any cleaning at all, and annual lamp replacement.

Naturally you want to know what a unit like this costs, right? FilterWater.Com carries units rated for 1, 6, 8, and 12 gallons per minute GPM. Costs begin around $150 for the smallest unit and go up to around $543 for the largest unit.

What about replacement bulbs? How much will they cost? Good question! FilterWater.Com carries replacement bulbs for Crystal Quest UV Sterilizer Systems rated for 1, 6, 8, and 12 GPM.
