ARSENIC FILTER

9 3/4 x 2 7/8
Arsenic Filter
Arsenic (As) is not easily dissolved in water. Therefore, if it is found in a water supply, it usually comes from mining, metallurgical operations or runoff from agricultural areas where materials containing arsenic were used as industrial poisons. Arsenic in water has no taste, odor or color. Arsenic and phosphate easily substitute for one another chemically; therefore commercial grade phosphate can have some arsenic in it. Arsenic is highly toxic and has been classified by the EPA as a carcinogen. These cartridges contain an Arsenic-selective Resin specifically designed to filter Arsenic V and Arsenic III. #RC-04008

NATURAL (ALKALIZE) IONIZER, MINERALIZER & OXIDATION CARTRIDGE

9 3/4 x 2 7/8
Natural (Alkalinize) Ionizer, Mineralizer & Oxidation Cartridge

Alkalinity is a measure of the capacity of water to neutralize acids. Alkalinity is primarily due to the presence of bicarbonate, carbonate, and hydroxide ions. Alkalinity acts as a pH buffer to deactivate acidity. Water with high alkalinity may have an offensive taste. These filters are tanks filled with a media blend of calcium and magnesium carbonates made from naturally occurring minerals. This media slowly dissolves into the water, raising the pH and making it less corrosive. One of the most important benefits of alkaline water (besides increasing the pH) is that it lowers Oxidation Reduction Potential (ORP).  6 Stage Filter - This filter has a 1 Micron rating - Click here to view 6 stage filtering details .

Phosphate & Coconut Shell GAC Filter Cartridge. #RC-04025

GAC Information - Activated carbon has been known as a miracle filter media by many researchers because of its unique ability to  remove offensive tastes, odor, color, chlorine and volatile organic chemicals, pesticides and trihalomethanes (a group of suspected carcinogens).

Briefly, activated carbon acts like a sponge, with a large surface area to absorb contaminants in the water. Many scientists believe this is a result of affinity that these chemicals have for carbon because of Van Der Waal forces.

Activated carbon is the preferred treatment and method recommended by the EPA to remove a host of potentially hazardous and possibly carcinogenic chemicals in drinking water.

CARBON Filter

The acid-washed coconut-carbon based formulation simultaneously removes chlorine taste and odor, and organic chemicals that contribute to taste and odor, while providing the particulate filtration and dirt-holding capacity of an efficient 5 micron sediment filter. Better tasting water is produced as carbon is used to its maximum advantage in minimizing pH levels while maintaining low pressure drop. This filter delivers extended life while removing sediment, chlorine taste and odor, and organic contaminants from water, aqueous solutions or suspensions. This carbon filter is also widely used in filtering organic solvents.

Filter Media: Acid-Washed Coconut Shell Granular Activate Carbon - 5 Micron Filter Removes; chlorine, chloramine, VOC's including insecticides, pesticides, industrial solvents, bad taste and more. #RC-04036

Flow rate: 6 GPM / Capacity: 24-36 months*

ARSENIC FILTER

20 x 4 5/8
Arsenic Filter
Arsenic (As) is not easily dissolved in water. Therefore, if it is found in a water supply, it usually comes from mining, metallurgical operations or runoff from agricultural areas where materials containing arsenic were used as industrial poisons. Arsenic in water has no taste, odor or color. Arsenic and phosphate easily substitute for one another chemically; therefore commercial grade phosphate can have some arsenic in it. Arsenic is highly toxic and has been classified by the EPA as a carcinogen. These cartridges contain an Arsenic-selective Resin specifically designed to filter Arsenic V and Arsenic III. #RC-04070

Flow rate: 6 GPM / Capacity: 6,000 gallons* (<100 PPM Hardness)
*capacity is an estimate only and is dependent on influent water contaminants and filter usage.

NITRATE FILTER

20 x 4 5/8
Nitrate Filter
Nitrate (NO3) comes into water supplies through the nitrogen cycle rather than via dissolved minerals. It is one of the major ions in natural waters. Most nitrate in drinking water is the result of contamination of ground water supplies by septic systems, feed lots and agricultural fertilizers. Nitrate is reduced to nitrite in the body. These cartridges contain a special nitrate-selective resin. Nitrate reduction is 90% to 95% and breakthrough is not affected by sulfate levels. The cartridges can be regenerated using sodium chloride brine. #RC-04069

Flow rate: 6 GPM / Capacity: 18,500 ppm Nitrate* (<100 PPM Hardness)
*capacity is an estimate only and is dependent on influent water contaminants and filter usage.

FLUORIDE FILTER

20 x 4 5/8
Fluoride Filter
Our CQ Fluoride Removal and Fluoride/Multistage Filter Cartridges use high capacity synthetic adsorbent media that is highly selective of Fluoride, Arsenic and Lead. The media is a synthetic aluminum oxide that is specifically processed to have a minimum of fines and other foreign matter. It removes metals through a combination of adsorption and chemical reaction with the media, therefore the removal is not dependant on ion exchange - Reduces fluoride below 0.5 ppm. #RC-04068

Flow rate: 6 GPM / Capacity: 15,000 ppm Fluoride* (<100 PPM Hardness)
*capacity is an estimate only and is dependent on influent water contaminants and filter usage.

NATURAL (ALKALIZE) IONIZER, MINERALIZER & OXIDATION CARTRIDGE

20 x 4 5/8
Natural (Alkalinize) Ionizer, Mineralizer & Oxidation Cartridge

Alkalinity is a measure of the capacity of water to neutralize acids. Alkalinity is primarily due to the presence of bicarbonate, carbonate, and hydroxide ions. Alkalinity acts as a pH buffer to deactivate acidity. Water with high alkalinity may have an offensive taste. These filters are tanks filled with a media blend of calcium and magnesium carbonates made from naturally occurring minerals. This media slowly dissolves into the water, raising the pH and making it less corrosive. One of the most important benefits of alkaline water (besides increasing the pH) is that it lowers Oxidation Reduction Potential (ORP).

6 Stage Filter - This filter has a 1 Micron rating. #RC-04093 Click here to view 6 stage filtering details

Filter Media: Mixed Blend. 1 Micron Rating

Flow rate: 6 GPM / Capacity: 12-18 months* (<100 PPM Hardness)
