Summary of NSF Water Filter Standards

Water Testing Blog — Fri, 30 Jul 2010 13:03:20 +0000

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.

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.

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.

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

Urine, Sweat, Skin and Cosmetics in Pool Water May Cause Cell Damage

Water Testing Blog — Tue, 27 Jul 2010 23:50:04 +0000

Taking a leak in the swimming pool… now shown to potentially cause harmful cell damage. As if the whole ‘Ewwwww! GROSS!!!’ factor shouldn’t have ALREADY given people incentive not to do it, right?

Well we all know how lazy OTHER people… ahem… can be.

Public swimming pools are more dangerous than you might think, a new study suggests. When sweat and urine, among other organics, mix with the disinfectants in pool water, the result can be hazardous to health.

The findings, announced this week, link the application of disinfectants in recreational pools to genetic cell damage that has been shown to be linked with adverse health outcomes such as asthma and bladder cancer.

Pool water represents extreme cases of disinfection that differ from the disinfection of drinking water as pools are continuously exposed to disinfectants. But with so many people cooling off and exercising in pools and water parks (339 million visits across the United States each year), the disinfectants are a must to prevent outbreaks of infectious disease.

Chlorine and Pee Don’t Mix

The problem occurs when the sanitizers mix with organic matter.

“All sources of water possess organic matter that comes from decaying leaves, microbes and other dead life forms,” said study researcher Michael Plewa, University of Illinois professor of genetics. “In addition to organic matter and disinfectants, pool waters contain sweat, hair, skin, urine and consumer products such as cosmetics and sunscreens from swimmers.”

These consumer products are often nitrogen-rich, and when mixed with disinfectants, these products may become chemically modified and converted into more toxic agents.

Long-term exposure to these disinfection byproducts can mutate genes, induce birth defects, accelerate the aging process, cause respiratory ailments, and even induce cancer, according to the researchers. While the new study did not examine actual effects on humans, it suggests such research might be warranted. ( source )

So listen up, all you nasty bastards and batardettes out there who find it too burdensome to cart your fun -in-the-sun frolicking butts to the bathroom: STOP PEEING IN THE POOL!

Oh, and for all of you who think, “It’s my pee, so it won’t hurt me,” all the other pee rule violators think the exact same thing.

Crystal Quest pitcher replacement filter

Manufacturer: Crystal Quest
Model Number: CQE-RC

4 stages of convenient filtration with a 2,000 gallon capacity.

In stages 1 and 2 KDF55 and KDF85 media reduce iron, mercury, copper, nickel, chromium, other dissolved metals, and harmful bacteria.

Stage 3 features an ion exchange resin that reduces heavy metals (such as lead, copper, aluminum) and lowers water hardness.

The fourth and final stage, a bed of granulated activated carbon (GAC) reduces chlorine by 99.9%, gets rid of bad tastes and odors, reduces pesticides and chemicals that are linked to cancer risks (i.e. benzene, THM’s, toxaphene).

How do you know if you need a water filter?

The answer, quite simply, involves testing your water. You can either test it yourself using a home water testing kit like the Water Quality Test Kit from SenSafe… or you can have a certified water testing laboratory such as National Testing Labs analyze your water.

In cases where homeowners suspect contamination, we always suggest using a certified water testing lab. Better to play it safe than sorry because… It’s your water, your health… and your LIFE!

Question: Do I Need to Clean My RO Filter?

Water Testing Blog — Thu, 22 Jul 2010 13:03:29 +0000

Recently we received an email asking a question we wish more people would ask… so they can save themselves a lot of grief, and in some cases, a lot of money!

Do I need to clean my reverse osmosis filter?

Given that many reverse osmosis systems use a tank to store water for use after filtration and the water, once it enters the storage tank, contains no sanitizers or disinfectants to prevent growth of ‘biologicals’ (aka: slime on internal surfaces)… Yes, you will want to clean out, at a minimum, the storage tank every once in a while. Consult your owner’s manual for specific instructions and cleaning intervals.

Most likely your manual will suggest the use of a Sanitizer Concentrate which contains chlorine. Below you will find examples of products for this application:

Single Pack

24 Pack

(General) Instructions for Use:

Water Softener Application: Mix the 1/2 oz. Packet of Sani-System with 4 gallons of water and then pour into salt tank. Manually regenerate the softener. Double the dosage for heavily fouled units.

RO ( reverse osmosis ) Units: Turn off RO system, drain storage tank and remove all filters and membrane. Pour 1/2 ounce Packet of Sani-System into the empty pre-filter housing. Reconnect and turn on incoming water. After the holding tank is full ( takes about 5 minutes ), let the system stand idle for 60 minutes. Drain Holding tank. Before the system is put back into service, flush the system with water to assure sanitizing solution is rinsed thoroughly from system. Re-Install filters and membrane occurring to manufacturer’s instructions. ( source )

The directions above serve as a general guide for use of the cleaning product. Please remember, though, to make sure you follow the directions outlined in you water filter’s manual for best results!

Stage 1 – A sediment filter which removes 99.99% of microbiological cysts, cryptosporidium, giardia, and ‘particles’ from the water.
Stage 2 – A granulated activated carbon (GAC) cartridge effectively absorbs a wide variety of organic contaminants such as volatile organic compounds (VOCs), chemicals linked to cancer (such as THMs and benzene), pesticides (like atrazine and simazine), herbicides, PCBs, and chlorine (removes 99.9%).

The activated carbon cartridge also reduces MTBEs and removes bad taste and odor from drinking water.
Stage 3 – An UltraFiltration (UF) membrane removes synthetic organic compounds ranging in size from 0.0001 to 0.005 microns in size, bacteria, viruses, colloids, and waterborne parasites. This stage also removes and/or greatly reduces salts and water hardness.
Stage 4 – A multi-stage filter which removes hundreds of other potentially harmful or aesthetically displeasing contaminants (if present in the water) and puts a final ‘polishing’ on the water.

How Do I Know if I Have Chlorine in My Water?

Most often we hear, “How can I get rid of the chlorine taste/smell in my water?” but sometimes people have such low amounts that they cannot tell for sure if they have ANY chlorine in their drinking water and/or they have an impaired sense of smell and cannot detect the chlorine odors… but know they don’t want to drink it regardless of whether or not they can smell or taste it.

The easiest way to test chlorine levels in drinking water, Chlorine Test Strips, and at this time we recommend using test strip products from two manufacturers: SenSafe and Watersafe.

Water Filter to Remove VOC’s, Oils and Hydrocarbons

Water Testing Blog — Mon, 05 Jul 2010 19:08:07 +0000

With all the talk about oil washing up on the shores as a result of the BP oil platform disaster, some people have started to ask a very smart question:

Could some of that oil somehow end up in my well water if I live close to the shore?

At this point no one can answer that question definitively, but rest assured plenty of people would prefer to err on the side of caution and have a water filter system capable of removing any trace elements of the BP disaster that may find their way into their water supply.

The Crystal Quest Mega Triple Undersink Water Filter, known by manufacturer’s part number CQE-US-00309 and good for proper filtering of up to 10,000 gallons of drinking water, uses a combination of three separate filter chambers:

Water flows through a sediment filter cartridge that removes sediment, silt, sand and dirt. This helps to extend the life of water softener and water filters and prevent damage to control valves and/or pumps.
In the second filter chamber, water flows through pre one – micron filter pads which remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

It then flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals — copper and zinc (Eagle Redox Alloy® 6500 and Eagle Redox Alloy® 9500) — that works using electro-chemical and spontaneous-oxidation-reduction (REDOX) principles. At this stage chlorine gets instantaneously and almost inexhaustibly oxidized iron and hydrogen sulfide get oxidized into insoluble matter which attaches to the filter media, heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals also get removed by the electrochemical process.

In the next stage, water flows through the ion exchange resin, further reducing heavy metals such as lead, copper, aluminum, and water hardness.

Next, water passes through granulated activated carbon (GAC), a compound universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants such as chlorine (99.9%), chemicals linked to cancer such as THM’s and benzine, pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and hundreds of other chemical contaminants potentially found in drinking water. It also works to greatly reduce and/or eliminate bad taste and odors in drinking water.

The last section of this filter chamber contains another one-micron filtration pad for further reduction of undesirable particles.
In the third filtration chamber water travel through a solid carbon cartridge designed to remove remaining volatile organic carbon compounds (VOC’s), insecticides, pesticides and industrial solvents.
