Today’s inquiry came to us from ‘Ric C’ who asked a very wise question about a water filtration unit he may wish to purchase (HomePure AP-0930):

Hi
Am dealing with a product that has an NSF certification, and below is the address;

http://www.nsf.com/Certified/DWTU/Listings.asp?TradeName=homepure&Standard=&ProductType=&PlantState=&PlantCountry=&PlantRegion=&submit3=SEARCH&hdModlStd=ModlStd

Does this mean the product is good?

Quite honestly, we have never seen the HomePure AP-0930 before but as we said previously, the marketplace has a ton of water filtration units out there and we seriously doubt that anyone could know the in’s and out’s of every single water filtration unit currently available for purchase.

With that said, we looked at the NSF credentials supplied by Ric and saw that this unit has tested and certified to NSF/ANSI STANDARD 042 (Drinking Water Treatment Units – Aesthetic Effects) for the reduction of chlorine taste and odor as well as NSF/ANSI STANDARD 053 (Drinking Water Treatment Units – Health Effects) for the reduction of volatile organic compounds (VOC’s).

While having NSF Certification does give the HomePure AP-0930 a bit of credibility, please keep in mind that not every water filter will work in every application — even with NSF, WQA, etc. certifications to back up its capabilities.

Think of it this way: A high quality hammer won’t do you a bit of good when you need to turn a screw.

Testing your water first?

Yes! Do it! Test your drinking water before spending money on a water filter!

Before investing in a water filter for your home or office make sure you test your water for as wide a range of potential contaminants as possible. Doing so could save you the expense and aggravation associated with installing a filter that addresses the wrong water quality issues.

Anything specific about the HomePure AP-0930 catch your eye?

We like the fact that the HomePure AP-0930 has NSF certifications. As we said before, it means the unit certainly has some credibility.

One thing we did not like about the unit dealt w/ it inability to filter out heavy metals such as lead, copper, iron, chromium, etc. In our opinion a well-rounded, general purpose water filter would also have the ability to remove/reduce levels of heavy metals in drinking water.

Older homes most likely contain metal piping and the majority of public water systems contain metal pipes, as well. “But, we live a newly constructed home.” Does not matter (in our opinion). Newer homes, while mostly containing PVC or some other type of plastic piping, still get connected to public water systems that contain miles and miles of metal pipes.

Depending upon the quality of the water when it leaves the water treatment plant, it has the opportunity to pick up anywhere from traces of metals to noticeable levels of metals as it travels through those miles of metal pipes to homes and offices on the water system.

Interesting fact: The literature for the HomePure AP-0930 water filter system did mention metals and say that metals in water may cause problems, but the HomePure AP-0930 does not remove/reduce metals.

Replacement filters for the HomePure AP-0930?

According to the NSF web site, the HomePure AP-0930 uses a replacement filter element with model number “AP-0931″. A quick search of three popular online water filter web sites (FilterWater.Com, FiltersFast.Com and WaterFilters.Net) and a google search yielded no locations where a person could purchase replacement filters.

Not a particularly good sign! What happens in 3 months or a year when the original filter kicks the bucket?

Moral of the story?

Not all water filter systems are created equal and even though some bear seals of certification and/or endorsement from well-known, reputable organizations such as NSF or WQA, not every one of those ‘certified’ products will clean up every possible water quality condition.

So, test your water to see what problems/issues it may have and THEN set about the task of locating the correct water quality improvement device for your water.

Look for products that bear the NSF and/or WQA logos, but do not assume the logo automatically means that a particular device will do what you need it to do.

Oh, and one last thing: Check to make sure you can easily acquire replacement filters for any water filter you consider buying.

Apparently some folks believe that water lacking ANY minerals will somehow cause problems for people who consume it as drinking water, cook with it, bathe in it, etc. While somewhat true that water produced by reverse osmosis may have ‘aggressive’ tendencies in certain plumbing situations, we have found that the largest ‘problem’ people have with demineralized reverse osmosis water… is its flat, boring taste and not its lack of minerals.

Water’s ‘taste’ comes from its dissolved minerals content so it stands to reason that without any minerals would also have no ‘taste’ — a problem easily remedied by the use of a remineralizing cartridge after the reverse osmosis system.

Don’t we need minerals in our water for health?

To this day we have not personally found any solid evidence to support the notion that an appreciable amount of necessary dietary elements gets absorbed by the body from drinking water — unless, of course, the water got used to wash down a vitamin or supplement.

Humans obtain the bulk of nutrients required for healthy living from the foods they eat… EXCEPT when they eat mostly (and too much) fried stuff like this.

Moral of the Story?

Eat healthy and drink clean water… and don’t buy into every ‘health trend’ and health fad’ that flashes on your television screen or in banner ads that pop up on web sites you visit.

The water we drink needs to have unwanted impurities removed. End of story.

If given a choice, we’ll take flat-tasting water over water containing potentially dangerous and/or bothersome levels of dissolved heavy metals (i.e. lead, copper, iron, manganese, chromium, arsenic, etc.) and other junk any day of the week!

“Do they make meters for pool testing that regular people can afford? Last yr our poolguy had a meter and I asked him how much it cost. He told me one thousand and some change. He lie to me so I would not go get one and he loses a customer?”

Wow. Interesting situation, right? Personally we’d have fired the guy for telling an outlandish lie. Yeah, sure, SOME equipment used to test pool water MAY cost upwards of a thousand dollars or more, but would the average pool maintenance person REALLY spend that kind of money? We doubt it.

We suggest, Lassie, that you take a look at the eXact Micro 7+ Pool Water Testing Meter… which costs well under a thousand dollars, by the way.

Combining the reliability and repeatability of a photometer w/ the dependability of proven chemistry methods such as DPD (for chlorine testing) and phenol red (for pH testing), the eXact Micro 7+ Pool Testing Meter puts the power of accurate water testing into the hands of the people who need it most: pool owners.

A definite advantage offered by this particular pool meter: Versatility. The pool testing meter tests for 7 critical pool water parameters directly and with the use of a conversion chart and correct reagentstrip it can test for a number of other water parameters, as well.

What comes in pool water test kit?

In the basic kit you will find everything you need to test for free chlorine, total chlorine, pH, calcium hardness, total alkalinity, dissolved copper, and cyanuric acid.

Chloramines? What are chloramines? Take a look at this earlier Water Testing Blog entry on Free Chlorine, Combined Chlorine and Total Chlorine and get a quick education on the topic!

Whether created as a byproduct of disinfection via free chlorine or the intended disinfectant in a water system, most people do NOT like the taste and odor of chloramines in their water.

Thankfully Pentek has come out with a product called the Pentek ChlorPlus 10 Chloramine Removal Water Filter Cartridge that fits in standard 10″ (x 2.5″) filter housings used in filter sytems produced by companies such as Pentek (obviously!), US Filter (recently acquired by Pentek!), Cuno, Filterite, Keystone, US Water, Water Resurces, Harmsco, and many other popular brands of water filtration systems. If your system uses a standard 10″ x 2.5″ housing, the Pentek ChlorPlus 10 ought to fit just fine!

Having said that last bit, please check the dimensions of your current filter and/or housing before ordering this product!

Looking for a 10″ replacement filter with NSF Certification? The Pentek ChlorPlus 10 uses a component tested certified to NSF Standard 42.

What does the Pentek ChlorPlus 10 remove/reduce? Using 1 micron carbon block technology this product (255416-43) should seriously reduce chloramine concentrations in drinking water and in doing so remove the (offensive) taste and odor associated with chlorine while also helping to pull out unwanted sediment, if present.

They just tried every trick they could think of to remove them until they came off… IF they ever came off.

These days, however, companies like Jack’s Magic specialize in making products that allow even the most inexperienced pool operator to quickly identify stains and remove stains.

Pool owners/operators who’ve tried Jack’s Magic Stain Identification Kit say it has saved them countless hours of wasted labor (scrubbing!) by taking the guesswork out of the satin id’ing and removal process.

How does it work? Quite simply, one of four (4) simple topical tests will pinpoint the nature of the stain and the included guide then tells users which Jack’s Magic Stain Removal product will work best to remove your swimming pool stain.

Where do pool water stains come from?

Typically stains result from unwanted water contaminants such as metals (i.e. iron, copper and manganese) which find their way into pool water via the fill water used to top off or initially fill up a swimming pool. Therefore we always suggest testing fill water before adding any chemicals. This simple step can save you tons of aggravation.

Why? Because if you discover ahead of time that your pool water contains metals, you have the opportunity to add the correct sequestering compounds and metal chelating compounds before adding the sanitizers that would bind with metals, form precipitates, fall out of solution, and create stains.

‘TommyT’ wrote in and asked, “Due to a bad cover and probably a hole in my liner we will need to add a lot of fill water this Spring. We have a well and know we will need to shock real well come Spring, but will we need to test for things like iron or is that all a bunch of hype about iron and metals ruining pools?”

Definitely NOT a bunch of hype, Tommy. We highly suggest that anyone needing to add water to their pool from a well, or ANY source for that matter, perform a number of tests on the water BEFORE adding chlorine, bromine, etc. If present in the water, minerals like iron and copper will immediately get oxidized by sanitizers ‘drop out of solution’. When that happens, they land on pool fittings, liners, steps/stairs, etc. and could leave permanent stains!

Yeah, sure, we would still suggest adding products like Sea Klear Metal Klear or Jack’s Magic Pink Stuff even after testing, but the testing will let you know if you need a lot of those products or just a normal maintenance dose.

Trust us when we say that the time and money spent testing the water before shocking does not compare to the amount of time and money wasted when people have to clean up stains caused by metals in their pool water!

• Chromium will appear in nature in one of three forms: Chromium(0), Chromium(III) or Chromium(VI).

• Chromium(0) gets used in the production of steel.

• Chromium(III) and/or Chromium(VI) may appear in compounds used for chrome plating, making dyes and pigments, tanning leather, and preserving wood.

• Chromium(III) aids the human body in its use of sugar, protein and fat, though health officials suggest not using excessive amounts of dietary supplements containing chromium compounds.

• Higher levels of chromium(VI) may cause irritation to the lining of the nose, ulcers in the nose, runny nose, and other breathing problems such as asthma, coughing, shortness of breath, and/or wheezing. While both Chromium(III) and Chromium(VI) in air can cause the aforementioned problems, effects occur at much lower concentrations of Chromium(VI) than Chromium(III).

• Chromium(III) and Chromium(VI) may exist in drinking water and have no associated tastes or odors.

• If ingested, Chromium(III) compounds tend to have less toxic tendencies and appear to cause fewer health problems than Chromium(VI) which causes anemia, irritation of the stomach, ulcers in the stomach, and ulcers in the small intestine.

• Some laboratory animals exposed to Chromium(VI) experienced sperm damage and damage to the male reproductive system.

• Some Chromium(VI) compounds may cause skin ulcers and a percentage of the population have extreme sensitivity to Chromium(VI) and/or Chromium(III) with allergic reactions manifesting themselves as severe redness and swelling of the skin.

• The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have determined that Chromium(VI) compounds are known human carcinogens. ( source )

• Some developmental effects have been observed in animals exposed to Chromium(VI). ( source )

Regulations, rules and recommendations pertaining to Chromium?

The EPA has determined that exposure to chromium in drinking water at concentrations of 1 mg/L for up to 10 days is not expected to cause any adverse effects in a child. The FDA has determined that the chromium concentration in bottled drinking water should not exceed 1 mg/L. The Occupational Health and Safety Administration (OSHA) has limited workers’ exposure to an average of 0.0005 mg/m3 chromium(VI), 0.5 mg/m3 chromium(III), and 1.0 mg/m3 chromium(0) for an 8-hour workday, 40-hour workweek. ( source )

What NSF/ANSI Standards apply to chromium in drinking water?

Standard 53, Standard 58, and Standard 62.

For more information on the specifics of those NSF/ANSI Standards and others, take a look at the NSF International Web Site. It offers a wealth of information for both the consumer AND water professionals alike.

Removing chromium from drinking water?

As far as units for the average consumer, pretty much only reverse osmosis makes any sense. One could use a process like distillation, but it has a flow rate that most likely would not meet homeowner needs and a much higher entry cost.

As an example of a reverse osmosis that carries NSF Certification for chromium reduction, you may want to take a look at the Pentek RO-3500 which has a price tag of under $270 and appears to offer a lot of filtering power for the money.

Pentek RO-3500 Reverse Osmosis Water Filters have tested and certified to NSF/ANSI Standard 58 for the reduction of Pentavalent Arsenic (Arsenic V), Barium, Cadmium, Copper, Hexavalent & Trivalent Chromium (Chromium VI & Chromium III), Cyst, Fluoride, Lead, Nitrate/Nitrite, Radium 226/228, Selenium, TDS and Turbidity.

“My husband and kids have no manners. We live in a place where temperatures hit the high 90′s for a good part of the year and since our tap water pretty much stinks (literally! yuck! so much chlorine!) we bought a Riviera filter by Brita and so far it has worked out GREAT — except that my family can’t seem to figure out how to refill the friggin’ thing so that when I get home I can have a glass of water, too! Do they make a larger pitcher or do I need to go out and get another Riviera and write my name on it?”

Ha ha. We have all grabbed a carton of milk or orange juice out of the fridge only to find that it had no weight and no contents. Now a similar heartbreaking event happens with filtered drinking water? What’s this So annoying! Well, lucky for you some folks at Brita must also have lazy family members because Brita does actually make a larger version of its very popular Riviera model.

The Riviera holds approximately 64 ounces of filtered drinking water at most which makes it kind of heavy when full so rather make a larger pitcher, Brita decided to make an in-fridge water dispenser called the Brita UltraMax Dispenser capable of holding an additional ten full 8-ounce glasses of cold, refreshing filtered drinking water more than its cousin the Riviera.

Brita Riviera Pitcher Water Filter

Brita UltraMax Water Dispenser

What do these Brita filters remove/reduce?

Both the Riviera Pitcher Filter and UltraMax Dispenser use the OB03 Water Filter, a filter certified by the NSF and the Water Quality Association to reduce levels of copper, mercury, cadmium, chlorine, and zinc in drinking water.

What NSF Standards does the Brita OB03 water filter certify to?

A very good question! While cruising around the web we found a number of sites claiming that the Brita OB03 water filter does a number of things… that we could NOT verify on the NSF, WQA or Brita web sites.

Therefore, we proudly present certification information about the Brita OB03 water filter that we COULD verify:

1) The Brita OB03 water filter has certified to NSF/ANSI Standard Number 53 (Health Effects) for the reduction of Copper, Mercury and Cadmium.

2) The Brita OB03 water filter has certified to NSF/ANSI Standard Number 42 which deals with the reduction of specific aesthetic or non-health-related contaminants (chlorine, taste and odor, and particulates) that may exist in drinking water for the following: Aesthetic chlorine, taste & odor, and zinc.

3) None of the three web sites mentioned earlier say anything about the OB03 having certifications for it’s ability to remove lead or volatile organic compounds (VOC’s).

Oh, and did we also mention you have the option of easily adding subtle, tasty flavors to the purified water it produces?

What importance does NSF Certified have?

Getting back to what really matters when it comes to a water filtration system, the PUR Pitcher Water Filter with PUR Flavor Options has passed independent laboratory testing and certified to NSF Standards for its ability to reduce levels of the following nasty water contaminants (if present to begin with):

• 2,4-D Reduction
• Atrazine Reduction — test for atrazine
• Benzene Reduction
• Cadmium Reduction
• Carbofuran Reduction
• Carbon Tetrachloride Reduction
• Copper Reduction — test for
• Cyst Reduction
• Mercury Reduction — test for mercury
• Simazine Reduction — test for simazine
• Tetrachloroethylene Reduction
• Toluene Reduction
• Trihalomethanes (TTHM) Reduction
• Chlorine Reduction – Aesthetic — test for total chlorine / test for free chlorine
• Nominal Particulate Reduction, Class I
• Taste and Odor Reduction
• Zinc Reduction — test for zinc

The PUR Water Filter in this water filter pitcher was successfully tested and certified by NSF International against NSF / ANSI Standards 42 and 53.

No, this filter will not protect your family against EVERY possible drinking water contaminant, but it does offer a decent amount of protection against some truly unpleasant compounds that don’t belong in your water.

Know what contaminants your drinking water contains

The best thing to do before ordering a water filter of ANY size, brand or type… Get your water tested to find out what you need to remove! If you have serious reason to suspect your water contains contaminants, consult with a certified water testing laboratory with proper accreditation. A lab like that will have the equipment and expertise to accurately assess any risks posed by contaminants in your water.

As an example, National Testing Laboratories, a water testing lab certified to perform water testing in pretty much every State in the US, offers three different water testing packages as well as a host of other contaminant-specific tests to the general public.

Below you will find information about the program, its goals, etc. If you want the full story, though, as in the official version as written by officials in New York City, go here now

Lead in Drinking Water from Household Plumbing

Water brought into the City from its reservoir system located upstate has virtually zero lead in it when it reaches the City. The water, however, has the ability to absorb lead from (older lead-containing) solder, certain types of metal fixtures and plumbing found in older buildings.

Therefore, if you live in an older building and/or just want to know more about the possibility that your water may contain dangerous, or at the very least no-so-safe levels of lead, then the following links on New York City’s own web site may prove quite useful:

• Important Information About Lead in Your Drinking Water
• Lead in Household Plumbing Brochure (downloadable PDF)
• Get the Run Your Tap Poster (downloadable PDF)

While we certainly DO applaud NYC’s efforts to inform the general public about the potential dangers posed by lead in its drinking water, and also for proving free lead in water testing to NYC residents who request it, we think the idea of advising millions of people to ‘run the faucet for 30 seconds’ will waste a whole lot of water.

On the other hand, the only other option, forcing building owners to convert over their old, lead-laden plumbing over to newer, safer plumbing components, would cost millions upon millions of dollars. Oh, and good luck trying to enforce THAT mandate in a city that size!

Hmmm… Quite a dilemma: Wasting millions (billions?) of gallons of perfectly good water (before it got to the City) which we will run out of one day to avoid spending 10′s of millions (billions?) of dollars to replace lead-containing components of an aging infrastructure… or biting the bullet and spending the money.

We dare not comment on that last one any more than we already have! We do not have the answers, but that does not mean we don’t think people need to ponder such dilemmas — as we often do.

So where does the leave New Yorkers?

For right now it leaves them with the heads-up that they need to monitor the quality of their tap water AND, at least for now, a free lead in water testing service they can use to assess the amount of lead in their drinking water.

It ALSO puts them in the same category as the rest of us: Responsible for the Quality of the Water We Use.

For a long time many people believed that only private well owners had sole responsibility for monitoring the quality of the water entering their homes… but obviously we can all now see that the miles of piping that may or may not contain lead — or leaks where unwanted contaminants could get in — presents itself as a noteworthy risk to folks with city/municipal water.

Therefore, we feel that everyone ought to consider testing their tap water from time to time. Unexpected leaks can occur at any time and may go undetected for years as they allow innumerable contaminants to enter the water supply, deplete disinfectant levels, and possibly find a nice place to hang out, grow and create new little contaminants of their own in the water supply.

Wow. The imagery from that last statement made us shudder. We hope it had the same effect on all of you.
