Water Softener That Does Not Use Salt?

Water Testing BlogHardness, Personal Water Filter, Reverse Osmosis, Water Filter, Water Softener

Today’s inquiry came to us from ‘Mike L’ who asked about ways to soften his water without having to use a salt-based softening system.

I live in a small twin (3 bed/1.5 bath) that I lease. When we moved in, we noticed the water was particularly hard (10 GPG) and it was causing dry skin after showers and other issues. We don’t use a lot of water and we don’t have much space (1,300 sq. ft.). I also don’t much prefer the saltiness of “softened” water. My landlord gave me the OK to install a simple filtration system. I’m looking for something cheap, compact and simple. I don’t need 0gpg either, if I can lower down to a 3-4 GPG I would be happy.

Seems simple right? I was thinking maybe a 400GPD RO system but they all come with faucets which makes me think they may not be usable to throw in-line on the water system.

Do you know of anything (under $1,000) I can do to clean up my water and make it just a little softer?

Good news, Mike! Recent developments in the water softener industry include water softeners that do not use salt as the primary treating agent. Reasons for the salt-free water softeners range from States like California putting a ban on them for environmental reasons to people (like yourself) simply not enjoying the taste and/or texture of the water produced by salt-based water softeners.

Eagle A1000AS Anti-Scale Saltless Water Conditioner

To the left you will see an example of a water softener that uses a special filtration media to remove calcium and magnesium from source water instead of salt. The unit also comes equipped with a sediment filter, solid carbon block filter for VOC’s (volatile organic compounds) and an Ultrafiltration Filter good for removing particles as small as .01 microns.

Mike, you mentioned reverse osmosis as a possible option and based upon what you said you wanted from the water treatment system, we don’t think that will work out as well as you’d like, though we do agree that reverse osmosis water filter do an excellent job of filtering water.

Reverse osmosis units do not connect up as inline filters as neatly and tidily as it sounds like you’d prefer. They require drains for ‘waste water’ that gets rejected by the membranes and flushed out during backwashing. Also, reverse osmosis water filters require power which means running a power line to the unit.

The Eagle A1000AS Anti-Scale Saltless Water Conditioner uses no power, requires no drain, uses no salt or environmentally harmful chemicals, and supposedly will help to remove existing calcium and magnesium deposits already clogging water lines.

Moral of the story?

Mike, we suggest having your water tested by a certified laboratory in your area or having a mail order service such as National Testing Laboratories perform a thorough analysis of your water. From the sounds of things, your faucets could possibly have more than just calcium and/or magnesium coming out of them and you will not know for sure until you test.

How Can I Check to See if My Water Filter is Working?

Water Testing BlogBacteria, Chlorine, Chlorine Testing, Coliform, Combined Chlorine, Ground Water, Hardness, Home Water Test Kits, Home Water Testing, Iron, Lead, mercury, Metals, TDS, Testing Devices, Total Chlorine, Water Quality Testing, Water Test Kit, Water Testing

Anyone that has taken the initiative to install a water filter or water purification device/system in their home deserves a bit of praise… and those that continue to take an interest in the quality of their water after installing a water treatment system deserve even MORE for their efforts.

As an example, ‘J. Mampilly’ from India installed a system and now seeks to determine if he has installed the correct unit. He asked,

I would like to know about how i can confirm the effectiveness of my water purifier. Labs in India that can certify and throw light on the camparative quality of water before and after using a water purifier. Thank You

Unfortunately we do not have familiarity with water testing laboratories in India and cannot directly assist with this situation. We can suggest, however, that you contact your local health department and ask them for a list of certified water testing laboratories in your area.

Before…

In order to know what type of filter or what filtering capabilities you should purchase, invest (yes, we said invest) in a thorough water analysis performed by a qualified water testing laboratory. Here, again, we suggest contacting your local board of health and asking them, for a list of certified drinking water testing labs. Alternatively, or if no labs exist in your immediate vicinity, you can use the services of accredited water testing companies such as National Testing Labs.

No matter what, though, always have your water tested BEFORE deciding on a water treatment system. Oh, and one more thing: Don’t think for one second that a salesperson doing an in-home water test has the same water testing tools or qualifications as a reputable water testing laboratory. Remember: 99% of all salespeople attempt to sell things and not accurately analyze a situation — especially if accurately diagnosing a situation could cost them a sale!

Total Dissolved Solids

And after!

As ‘J. Mampilly’ has done, we should ALL take an interest in comparing the quality of water that comes out of our water filter systems. Only then will we know if the money we invested in (not spent on!) a quality drinking water filter system performs as expected.

Testing water quality beforehand gives us not only an idea of what we need to filter out of our water, but also a checklist of water quality parameters to monitor post-filtration. Should follow up water testing reveal that these ‘issues’ did not get corrected or suddenly show up months after the installation of a water system, perhaps the water filter has stopped working or never really worked properly in the first place and needs service of some sort.

And in conclusion…

Many people go through life ‘deaf, dumb and blind’ when it comes to the quality of their water — until an (initially) unexplainable health problem pops into their life. Then, and unfortunately sometimes too late, those same people get very interested in the quality of their water and want to punish or otherwise penalize others for allowing them to consume tainted, polluted and/or contaminated drinking water.

Although we feel much sympathy for the victims of poor quality drinking water, most of us here in the United States have the ability to at least once every great while perform basic testing for critical water quality parameters such as heavy metals (i.e. lead, mercury, copper, iron, etc.), coliform bacteria, pesticides (i.e. atrazine and simazine), chlorine levels (free and/or total), total hardness, total dissolved solids, and many others.

Many times the contaminants in a water supply will have no taste, carry no odor and not appear before the naked eye. Only testing will alert you to their presence.

Every so often we receive questions from readers who ask something along the lines of, “What do most people ask about?”

Seemed odd at first (several years ago), but after getting asked the same thing so many times we eventually came to the conclusion that a good number of people really and truly don’t know what questions they ought to have about the quality of their drinking water.

Therefore, for your reading pleasure we will now give a list of the 10 most popular topics on Water Testing Blog for the month of August (2011):

  1. Free Chlorine, Total Chlorine and Combined Chlorine
     
  2. Testing for Fluoride in Water
     
  3. Converting Hardness: Grains per Gallon to Parts per Million
     
  4. What is DPD?

  7. Dirty Pool Water Can Make You Very Sick
     
  8. Testing for Chlorine in Drinking Water
     
  9. Lead in Soil
     
  10. Private Well Water and Natural Gas Drilling

In no way does the above list begin to scratch the surface of what curious folks read on our site, but it may help you decide what questions YOU want answered… and if you come up with a question or topic you’d like us to address, send it to us using our submit a comment/question form.

It did, however, kind of shock us that hydraulic fracturing (aka: fracking), a means of extracting natural gas from shale buried deep beneath the Earth’s surface, came in so low on the list given the amount of (bad) publicity hydraulic fracturing has received in the past few years.

We also found it somewhat odd that bacteria in water did not make a single appearance in the list but then again, most folks in the United States have city/municipal water and make the assumption that city/municipal water couldn’t ever contain something as common as bacteria — and that, friends, can sometimes become a dangerous assumption to make!

As usual the warmer weather (in most of the US) has brought out the folks who have questions about pool water and how best to take care of it. Today’s question comes from ‘ActionLassie007′ who asked,

eXact Micro 7+ Pool Testing Meter
eXact Micro 7+
Pool Testing Meter

“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. :P

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.

Chesapeake Bay Getting Better, But Still Far From Good

Water Testing Blogalkalinity, Environmental, Hardness, Nitrate, Nitrite, pH, TDS, Test Strip, Testing Devices, Water Quality Testing, Water Test Kit, Water Testing

Usually we report about water conditions in a region getting worse but today we proudly announce that we recently stumbled across some news about improved water quality in a region. It feels good to deliver good news every once in a while, ya’ know?

So anyways, an independent environmental monitoring group in the Chesapeake Bay area (Chesapeake Bay Foundation) announced that results of recent water quality testing indicate definite improvements in the bay’s overall condition.

With its crab population rebounding and water quality slightly better, the Chesapeake Bay is showing signs of improvement, the region’s leading environmental group says, but the estuary remains seriously impaired and needs a strict pollution “diet” to ensure its restoration.

The Annapolis-based Chesapeake Bay Foundation upped the estuary’s overall health score by three points in its latest “state of the bay” report, while warning that it remains in critical condition, barely above a failing grade.

“That the bay is getting better is a huge development, but sadly not the whole story,” William C. Baker, the foundation’s president, said in a release accompanying the report. “Dead zones, fish kills and water contact advisories are constant reminders of how far we still must go.” ( source )

Got a body of water in your area that you’d like to keep an eye on? The Chesapeake Bay Foundation probably uses quite a few advanced tools such as multi-parameter meters to measure a wide range of critical water parameters but in all honesty, sometimes using simple tools such as a TDS Meter or Eco-Check, a very popular product which tests for nitrates, nitrites, hardness, total alkalinity, and pH all with a single dip of a test strip and typically costs less than $14.00 for a bottle of 25 tests.

Drastic changes in basic water quality parameters sometimes serve as warning signs that other, more serious water quality problems exist.

Dangerous Levels of Lead Found in School’s Brass Valves

Water Testing BlogHardness, Home Water Testing, Lead, manganese, Metals, sensafe, Water Quality Testing, watersafe

Since we started this blog articles about ‘new’ dangers posed by lead in water have come up from time to time… and we have posted articles about them as soon as we became aware of them. Does that make us sensationalists or couriers of messages and news intended to make people cognizant of potential dangers posed by the possibility of lead in their drinking water?

Filters Fast: WaterSafe Lead in Water Test Kit
WaterSafe Lead in Water Test Kit

Filter Water: SenSafe Water Metals Test Kit
SenSafe Water Metals Test Kit

Filters Fast: Manganese in Water Test Kit
Manganese in Water Test Kit

You will have to answer that question for yourself, and while you ponder that query, please also take a moment to think about the possibility that any number of manufacturing errors could possibly result in the improper distribution of lead in brass fittings — as alleged by researchers investigating alarmingly high levels of lead found in water produced by water fountains after technicians took several steps to make them lead-free.

Hidden elements in drinking-water lines can shed large amounts of lead, a toxic heavy metal. And it’s quite legal, even if it does skirt the intent of federal regulations.

University researchers, who uncovered this problem the hard way, have published a case study on the offending hardware in the November issue of the journal of the American Water Works Association.

Lead adds ductility to brass, making it easier to bend or machine into desired shapes. To limit the risk of lead poisoning, U.S. law prohibits new brass plumbing parts in drinking water lines from containing more than 8 percent lead by weight. Yet two shut-off valves containing only about 6.5 percent lead leached toxic amounts of the metal into drinking fountains at the University of North Carolina.

What happened: During manufacturing, the lead did not uniformly distribute throughout the brass, but ended up preferentially settling at or near the surface. As a result, the outside of affected valves—the side visible when looking at a water line (see photo)—slightly exceeded the lead limit. That shouldn’t have posed a health problem, since this surface doesn’t touch water. However, the valves’ interior surface, which does, contained at least 18 percent lead by weight. ( source )

After reading that, and seeing how careful steps taken by knowledgeable people failed to get rid of all the lead in the plumbing of water fountains on a college campus, would you still think us alarmists by giving the topic a few minutes of publicity?

What levels of lead in water pose a danger?

The United States Environmental Protection Agency has ruled that public water systems may not contain more than 15 ppb of dissolved lead and that any system found to have that amount or greater in the water it distributes must take immediate steps to remedy the situation.


Total Hardness
Water Test Kit

While that sounds like a great plan, the fact remains that pretty much all lead found coming out of faucets in people’s homes entered the water at some point after the water left the water treatment facility. Old water service lines, fittings in people’s homes, and older solder used to join pipes all could contribute lead (and other metals) to the water they come in contact with — especially if the water has aggressive tendencies.

Aggressive tendencies? Water can have a bad attitude and start fights? Well, no, but throwing water on someone in a bar or dance club will put them in a bad mood and possibly start a fight.

When we say water has aggressive tendencies, we mean it has low total hardness and/or a low pH; both of which would make the water want to pull elements (metals and other things) out of any surfaces it comes in contact with.

And in conclusion…

Enough evidence exists out there pointing to the fact that dissolved metals in water have a probability of causing health problems that we do not know WHY anyone would not want to test their drinking water (note: tap water and well water can both can contain dangerous concentrations of dissolved metals) for the presence of metals periodically.

Should You Test Your Water If You Have City/Municipal Water?

Water Testing BlogChlorine, Chlorine Testing, City Water Test, Copper, Free Chlorine, Hardness, Home Water Testing, Iron, Lead, manganese, Metals, Total Chlorine, Water Quality Testing, Water Testing

We get asked this a LOT. Quite a few people write in ask things like, “I have city water, but it tastes funny. Should we test it?” or “The water in my town tastes different on different days. Is that a problem?”

Filter Water: All-in-One Water Test Kit
All-in-One Water Test Kit

Filter Water: Water Quality Test Kit
Water Quality Test Kit

In both cases, and so many more, we would suggest getting a test kit such as the Water Quality Test Kit made by SenSafe or the All in One Water Test Kit made by WaterSafe… and doing some preliminary testing of their own.

In most cases people complaining about city water will have problems caused by contaminants such as dissolved metals (i.e. lead, iron, copper, etc.), chlorine content (free and/or total), total hardness (calcium and/or manganese), and/or rotten egg smells caused by dissolved hydrogen sulfide.

If you get unusual or questionable results, definitely seek the services of a certified water testing laboratory; preferably one not affiliated with a water filter system distributor.

What about bacteria?

We also get asked quite often about the likelihood of harmful bacteria showing up in tap water. Despite the efficiency of modern water treatment facilities and the exemplary track records most have when it comes to the quality of the water they produce, one must always remember two things:

1) Accidental machinery malfunctions can occur.

2) City water travels through lots and lots of piping before it gets to your tap… meaning it passes over thousands of joints where leaks in the pipes could allow the introduction of dangerous bacteria.

If you suspect for any reason that your water supply may contain bacteria, although home drinking water test kits work well as screening methods, times like this call for the services of a certified water testing lab.

You local health department can suggest a water testing laboratory in your area or you can use a mail order laboratory such as National Testing Labs.

Water Filter Pitchers and Temperature

Water Testing BlogBacteria, Chlorine, Coliform, Copper, Hardness, Iron, Lead, mercury, Metals, Pesticide, replacement water filter, THM, Water Filter

Everyone loves the taste of fresh, clean filtered drinking water, but not everyone likes their water ice cold or as cold as it gets when stored in a refrigerator. How do we know this? Simple: Martha wrote in and asked,

I’m thinking of getting a water filter pitcher. Must it be kept in the refrigerator in order for the filter to work? I prefer room temp. water.

Thanks, Martha


Hot Water Filter Housings

We knew that hot water posed a problem for certain types of filters and filter housings — hence the need for special hot water filters & housings — and we knew that frozen water would not work all that well, either (obviously!), but as for whether or not a filter would perform all that much differently at room temperature versus the temperature of a refrigerator, we never gave that a whole lot of thought.


Crystal Quest Pitcher Filter

Until now.

Our quick research has determined that water filter pitchers ought to work just as well at room temperature as they would in a refrigerator. We do, however, suspect that one could possibly need to replace the filters more frequently since warmer temperatures in the filter would make an excellent breeding ground for bacteria. We suspect that water pitcher filters that use certain blends of KDF Media may prove more resistant to bacterial growth than filters that do not use KDF Media.

The Crystal Quest Pitcher Water Filter does something that similar products made by other leading water pitcher filter manufacturers do not. It uses a total of FIVE stages of filtration.


Crystal Quest Pitcher
Replacement Filter

  • A one micron sediment pre-filter takes out dirt, rust, sediment and any other large particles.

  • In filter stages 2 & 3… Blends of KDF55 and KDF85 resin media reduce dissolved metals (i.e. iron, mercury, copper, nickel, chromium) and harmful bacteria. As we mentioned before, KDF resin media also has properties which help to prevent the growth of bacteria in the filter.

  • In the fourth stage of filtration a bed of ion exchange resin further reduces heavy metals including lead, copper and aluminum. This stage also reduces water hardness (calcium and magnesium).

  • The fifth stage of filtration contains granulated activated carbon (GAC) reduces chlorine (99.9%), bad taste and odors. It also reduces pesticides and chemicals that science has linked to increased cancer risks in humans (i.e. VOC’s, benzene, TTHMs and toxaphene).

Countertop Nitrate Removal System — Dual Filter

Water Testing Blogatrazine, Chlorine, Copper, Environmental, Ground Water, Hardness, hydrogen sulfide, Iron, Lead, mercury, Metals, Nitrate, Pesticide, replacement water filter, simazine, THM, Water Filter, Water Testing, Well Water

Nitrate Test Strips

We have posted a number of articles about nitrates in drinking water and given a number of links to products that can remove nitrates from drinking water… and today we found out that FilterWater.Com has started carrying a highly effective nitrate removal system made by Crystal Quest that costs less than $150, features a dual filter system containing a total of 7 filtration stages, and qualifies for free shipping.

Do I have nitrates in my drinking water?

Nitrates occur naturally in the environment and may come from any number of sources in nature including, but not limited to, animal waste that filters down into the aquifer. Wells tapping into that aquifer as a source of drinking water then pull the water to the surface where it gets used by the well owner for cooking, drinking, bathing, etc.

What harm can nitrates in drinking water do?

The USEPA summed up the effects of nitrates in drinking in the following ways:

Short-term: Excessive levels of nitrate in drinking water have caused serious illness and sometimes death. The serious illness in infants is due to the conversion of nitrate to nitrite by the body, which can interfere with the oxygen-carrying capacity of the child’s blood. This can be an acute condition in which health deteriorates rapidly over a period of days. Symptoms include shortness of breath and blueness of the skin.” ( source )

Long-term: Nitrates and nitrites have the potential to cause the following effects from a lifetime exposure at levels above the MCL: diuresis, increased starchy deposits and hemorrhaging of the spleen.” ( source )

How can I get rid of nitrates in my water?

We started this posting by saying that Filter Water now carries a dual filter counter top nitrate removal system… so now we figure we ought to tell you a little more about it.

Stage 1 — This product uses as dedicated nitrate removal filter. Water first flows through a nitrate-selective resin cartridge designed to reduce nitrate levels in water by 90 to 95 percent. The cartridge has an expected nitrate capacity of approximately 5500 ppm and owners can regenerate (aka: recharge, flush out, clean) the cartridge using a sodium chloride brine solution when it gets full.

Stages 2 & 7 — Pre and post one-micron filter pads remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter in the water.

Stages 3 & 4 — Specially formulated beds of copper and zinc (KDF-55D, and KDF-85D) use a process known as oxidation-reduction to exhaust any chlorine in the water and convert iron and hydrogen sulfide into insoluble matter which attaches to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, etc. also get removed during stages 3 & 4.

Stage 5 — Ion exchange resins reduce heavy metals such as lead, copper and aluminum further and also reduce water hardness by filtering out magnesium and calcium.

Stage 6 — Granulated Activated Carbon (GAC), a universally recognized and widely used adsorbent for a wide variety of unwanted drinking water contaminants such as chlorine (99.9%), chemicals linked to cancer (i.e. THM’s, benzene) pesticides & herbicides such as atrazine and simazine, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and hundreds of other chemical contaminants which could possibly exist in your water supply.

Other features of the Dual Filter Nitrate Removal System?

Many people simply do not want to mess around with plumbing under their sink so a unit like the Crystal Quest Dual Filter Nitrate Filter System which requires no plumbing will work out beautifully.

The unit sits quietly next to the sink on the counter top and connects easily to pretty much any standard kitchen faucet. It also comes with a diverter valve which allows people to switch between filtered and unfiltered water with the flip of a switch.

Not digging the stark white appearance of the filter? Don’t worry! You have the option of ordering the unit with a chrome finish if that better suits the decor of your kitchen.

How long will the filters last and what do replacements cost?

The manufacturer estimates that the filters ought to last between 1 and 3 years depending upon the initial quality of source water. Keep in mind, though, that a soaking of the nitrate-specific cartridge in sodium or potassium chloride solution at room temperature will recharge the cartridge for additional use.

  1. Remove cartridge from unit
  2. Immerse the cartridge in a sodium or potassium chloride and room temperature water for a period of 30 minutes
  3. Rinse off and then soak the cartridge for 30 minutes in salt-free water
  4. Shake excess water off of and out of the cartridge
  5. Place the cartridge back in the filter housing
  6. Run through the systems for a period of 5-10 minutes

When it comes time to replace the nitrate-specific filter cartridge it will cost around $50 and the 6-stage filter cartridge will cost about the same.

Inexpensive Countertop Fluoride Filter

Water Testing BlogArsenic, Arsenic in Water, Chlorine, Copper, Fluoride, Hardness, hydrogen sulfide, Iron, Lead, mercury, Metals, Pesticide, Water Filter, Water Testing

No Cartridge Fluoride Filter

While the jury has not come back with a decision on whether or not fluoride in drinking water poses a serious health risk to people who drink water spiked with it, if you don’t want it in your water Crystal Quest has recently come out with a convenient, easily installed countertop water filter for fluoride — and many other unwanted potential drinking water contaminants.

Crystal Quest manufactures a product called the Countertop Disposable Single Fluoride Multi PLUS Water Filter System which installs in seconds and effectively removes fluoride AND hundreds of drinking water contaminants — if present in the water to begin with.

Water travels through a series of seven filtration stages in this unit. You will find detailed information on those stages below:

Pre and Post One-Micron Filter Pads: Used in stages 1 and 7, this filtration method removes suspended particles including silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved solid matter.

Fluoride Removal Cartridge: Used as the second stage of filtration, water flows through a fine mesh synthetic aluminum oxide absorbent media which has an extremely high affinity for fluoride, lead and arsenic. Through a combination of adsorption and chemical reaction the media effectively removes metals over a wide pH range.

How much fluoride can the filter hold before it needs servicing? The filter will reduce 10ppm feeds to 0.2ppm for a total of 6,000ppm fluoride removed.

KDF Media Bed: The third and fifth stages of filtration feature proprietary blends of high-purity KDF resins (KDF-55D and KDF-85D) which work using electrochemical and spontaneous oxidation-reduction (REDOX) principles. In these stages compounds such as chlorine get neutralized. Laboratory testing has shown that combination KDF/GAC cartridges can remove more than 99% of chlorine from greater than 20,000 gallons of water.

During these stages iron and hydrogen sulfide also get oxidized and become an insoluble substance that attaches to the surface of the media. Additionally, heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals get removed from the water by an electrochemical process at this point.

Ion Exchange Resin: The fourth stage of filtration uses an ion exchange to further reduce/remove heavy metals such as lead, copper and aluminum. This stage also acts a water softener by reducing calcium and magnesium levels (aka: total hardness) in the water.

Granulated Activated Carbon (GAC): The sixth stage of filtration makes use of granulated activated carbon, a material universally accepted as a highly effective means of eliminating a wide range of unwanted contaminants such as chlorine, potential carcinogens (i.e. THM’s, benzene, etc.), pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and many more chemical contaminants that may show up in water. Many of these compounds create a ‘bad’ color, taste and/or odor in drinking water, but not all.

Important note regarding carbon filters… Some manufacturers use a lesser grade of carbon, but this filter uses a highly porous, and therefore more useful, carbon derived from coconut shells.

How do I know if I need a water filter like this one?

If you have concerns regarding fluoride in your drinking water, contact your local water department and ask for a copy of the most recent drinking water report. Some water districts have made their annual reports available online so you may want to look on your water district’s web site first.

If your concerns deal with potential water contaminants that may have entered your water supply after it left the water treatment plant — bacteria, lead, heavy metals, etc. — then at-home drinking water test kits like the following may work just fine for you.
