A while back we wrote about a dual filter nitrate removal system manufactured by Crystal Quest. Since then we have received several emails asking us if Crystal Quest made a dual filter that mounts under the sink because they have limited counter space but want the benefits offered by a dual filter.

As a matter of fact, Crystal Quest DOES manufacture a dual filter nitrate filter system that mounts under the sink… and it comes with a third filter chamber (a carbon block filter designed to remove volatile organic carbon compounds (VOC’s), insecticides, pesticides, and industrial solvents) as an added bonus. OK, so they really call it a triple filter, but using our ‘math’ you can call it a double filter nitrate removal water filter… with a single carbon block filter on the side. Ha ha.

Why did they add the third filter?

We don’t know the actual reason, but we suspect Crystal Quest knows that nitrates will often appear in drinking water found in rural/agricultural areas where compounds such as atrazine may also show. Adding the carbon block filter means the filter will have the ability to reduce/remove nitrates AND volatile organic carbon compounds (VOC’s), insecticides, pesticides, and industrial solvents.

Manufacturer’s Product Number: CQE-US-00324

Replacing the filters?

Changing out filters on this unit takes very little time and the replacement filters don’t cost an arm and a leg, either.

Life expectancy for the filters?

• Roughly 6-9 months for carbon filter
• About 10,000 gallons (or 1 to 3 years) for 6-stage filter
• Around 1 year for the nitrate removal filter

Nitrate & Nitrite 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.

In our experience, four basic groups of people ought to consider installing a nitrate filter on their drinking water line and/or main water line, though other folks may have reason to as well:

   * Anyone who has well water and lives in an area where regional flooding takes place on a regular or semi-regular basis. Nitrates occur naturally in the environment and if a well head gets covered by flood water, any crack or fissure in the well covering could allow nitrates, bacteria and other potentially harmful contaminants to infiltrate the well.

   * Anyone who has well water and lives in an area close to certain types of manufacturing facilities — most notably fertilizer factories. Sometimes runoff containing nitrates from facilities infiltrate local water supplies… by accident, of course.

   * Anyone who has well water and lives in or close to areas engaged in agriculture (farming). Many of the fertilizers used by even the smallest of farms contain nitrates and often times those nitrates will get washed away by rain water and make their way into aquifers. Additionally, farms that raise animals may not always dispose of nitrate-rich animal waste and just as in the case of nitrates from fertilizers, the nitrates from animal waste often find their way into aquifers.

First Line of Defense

Without testing, one will never know if their water contains potentially harmful contaminants. Therefore, a homeowner’s first line of defense against drinking water contamination is and always will be testing their drinking water.

For nitrate and nitrate in drinking water testing, SenSafe manufactures an easy-to-use test strip that measures both nitrate and nitrate concentrations in water at the same time and yields results in about one minute.

Should you rely solely upon a test strip to tell you whether or not your water contains potentially harmful contaminants? Not at all. Certified testing labs such as National Testing Laboratories specialize in analyzing drinking water for contaminants and follow strict government approved and/or recommended protocols when performing any testing.
