If there are stains or buildup on your sinks and bathtubs...if you have to use large amounts of soap to clean dishes or wash your hair...or if your water tastes or smells odd, you probably have hard water.

If left untreated, the minerals in hard water will cause yellow stains on plumbing fixtures and be deposited as scale, eventually clogging plumbing and shortening the life of appliances like washing machines, water heaters and dishwashers. Scale deposits not only cut down on the efficiency of these appliances, they cost you money, increasing both energy and maintenance bills.

pH Water Treatment Products – Professional Series WTS eliminate the effects of hard water by removing the Iron,  calcium, magnesium and radon found there. Water is treated at the point-of-entry to the home, extending the useful life of water heaters, coffeemakers, humidifiers and household plumbing by as much as 30%.

pH Water Makes a Difference You Can See & Feel

In the Bathroom

Soap and shampoo will lather better. Hair and skin will feel noticeably cleaner, softer and not as dry. No soap scum or mineral deposits to clean off sinks, showers, tubs or toilets.

In the Laundry

Clothes will be softer, cleaner, whiter and brighter. Plus they will last longer. Using soft water increases the life of clothing, towels and linens up to 33%. Without hard water service issues, washing machines last longer, too.

In the Kitchen

Dishes will clean more easily, and be spot free, without the film glasses get when etched by mineral-laden water.

Throughout the House

Water-using appliances will last longer and run better. Why?, because water heaters, washing machines and dishwashers using hard water can wear out 30% faster.

How a Water Softener System Works

Hard water passes through the media tank that contains resin beads coated with Sodium or Potassium ions. The calcium and magnesium ions are exchanged for (Sodium / potassium) ions, thus treating the water.

When the beads have trapped the hardness and need to be regenerated, the control valve charges them with brine (Sodium / potassium and water solution) from the brine tank. As regeneration occurs, calcium and magnesium (hardness) ions are freed from the beads, replaced with sodium or potassium ions; and the system is ready to soften water again.

How the Water Treatment Regeneration Process Works

The control valve will manage the frequency of recharging the resin beads that clean the water and flushing the contaminated water out of the system.

Automated Control

These automated systems regenerate based on actual water usage. If you are away on vacation or if you have guests staying, the control will adjust accordingly. Computerized controls are programmed with grain capacity of the softener, water hardness and how many people are in the home. Since this type of unit only regenerates when necessary. It is the most efficient in energy and salt pellet usage.



The largest single section in the "EPA Regulated Water Contaminants" published in Water Technology magazine, is the section on Organics (including VOCs, or "Volatile Organics"). In this category the EPA lists 32 very nasty chemical contaminants — many with familiar names like benzene, 1,1 dichlorethylene, carbon tetrachloride, dioxin, styrene, toluene, chloroform, and vinyl chloride. To give an idea of the extensiveness of this list, a single one of the 32 items is "Total Trihalomethanes", a category made up of still uncounted chemicals, assumed to number in the thousands that are formed when water containing organic matter (i. e., virtually all water) is treated with chlorine. The maximum allowable level for trihalomethanes, which are suspected cancer causers and are present in virtually all chlorinated tap water, is only 1/10 of one part per million. For the Organics category, the primary treatment in all cases and the only recommended treatment in most cases is activated carbon.

The EPA's Pesticides category lists 14 familiar poisons such as Aldicarb, Chlordane, Heptachlor, and Lindane. In all 14 cases, activated carbon is the only recommended treatment. Of the 12 Herbicides listed (2,4-D, Atrazine, etc.), activated carbon is the only treatment recommended.

For Organics, Pesticides, and Herbicides, the standard treatment, and in most cases the only treatment recommended, is activated carbon.

When people say water filter, they most frequently mean a carbon filter of some variety, because since the Egyptians discovered that storing water in charcoal made it stay fresher and taste better, carbon has been a standard feature in water treatment. Its centuries of popularity attest to its effectiveness.

If you are considering a home water filtration system, here are some things to keep in mind:

Chlorine was not considered in the discussion above because EPA does not consider it a water contaminant. Although this is patently absurd, it is also politically expedient and not likely to change soon. (Keep in mind that all EPA maximum contaminant allowable are politically negotiated figures that do not necessarily have any basis in reality. They represent a compromise between the ideal and what can practically be done by water treatment plants.) Chlorine removal is what carbon is best at, and nothing else equals carbon's ability to remove chlorine.


The EPA has set a lifetime health advisory (LTHA) level for two PFAS in drinking water: perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). The LTHA level is 70 parts per trillion (ppt) for PFOA and PFOS combined.  THE PFOA and PFOS LTHA is the level, or amount, below which no harm is expected from these chemicals. There are other PFAS compounds that do not have LTHA levels.

My drinking water contains PFAS. What should I do?

MDHHS advice is based on the best available science and, per the EPA Lifetime Health Advisory, protective of everyone, including pregnant women, young children, and the elderly. When concentrations exceed the EPA Lifetime Health Advisory Level of 70 ppt for perflourooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) (singly or combined total concentration), MDHHS recommends bottled water or filters. When detections are lower than the EPA level, we also have recommended bottled water or filters to be used in situations when we cannot be confident that these chemicals will continue to be at low levels in your well water. If you have been notified by MDHHS or your local health department that PFAS were found in your well water sample, and that you are near a PFAS source, MDHHS recommends that you do not use your well water for drinking, cooking, making baby formula or food, washing fruits or vegetables, or brushing your teeth, unless your well water is filtered using a system certified to reduce PFOA and PFAS. Touching the water is not harmful. You can bathe, wash dishes, launder your cloths, and clean with your well water.

May I bathe or swim in water containing PFAS?

You may bathe and swim in water containing PFAS. The PFAS do not easily absorb into the skin. It is safe to bathe, as well as do your laundry and household cleaning. It is also safe to swim in and use recreationally. Getting water with PFAS on your skin will not harm you.

Do carbon filters remove Pfas?

The number of affected people is likely much higher but data are limited. Most in-home water filters cannot effectively remove PFAS chemicals, though activated carbon filters and reverse osmosis can eliminate some forms of the compounds.Aug 12, 2016




Types of Filtration Systems

Both granular activated cat carbon (GAC) and reverse osmosis (RO) filters will reduce PFAS substances.

How long does Mixed (GAC) carbon and KDF last?

Whole house systems can do up to about 1,000,000 gallons.  This can vary depending on your contaminant levels but for normal use for an average family of four. Most systems like this will last about 5 years or 1,000,000 gallons whatever comes first. The pH Prescription ™ control valve has a built in meter to keep track of your gallons used and this cannot be changed or cleared out. It’s like an odometer on your car just keeps adding up. This way you will know when you need to replace the media inside the tanks.


Kinetic Degradation Fluxion, or KDF

KDF is patented and proven to remove chloramines, chlorine, bacteria, iron, fungus, algae, hydrogen sulfide, most heavy metals and other contaminates.  KDF is brass, made of 50% pure copper and 50% pure zinc.  In water this produces an electro-chemical reaction that converts free chlorine into simple chlorides.  Some of the harmful components are changes into harmless ones.   KDF will remove more than 95% of chlorine before it hits your carbon filter, extending the life of the carbon by 15 times and letting it focus on other pollutants.  The electrolytic field inhibits microorganisms and forms peroxide and hydroxyl radicals.  KDF meets EPA and FDA standards for zinc and copper because the copper and zinc ions tend to reattach to the KDF media.  It doesn't remove minerals and is best used in tandem with carbon filters for truly effective filtration.

KDF 55 and 85 Provide Non-Chemical Water Treatment Media for Lead Removal and Other Heavy Metal Removal from Water

Redox media, non-chemical water treatment remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals.

When filtered through KDF® media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the media. Other heavy metals bond to the media and may be recovered when the exhausted media pass through a copper smelter.

  • New Jersey's Department of Environmental Protection and Energy uses KDF 55 redox alloy medium in point-of-entry treatment systems (POET) to remove mercury in residential applications. KDF media consistently reduce mercury from initial concentrations of 13 ppb through 24 ppb (parts per billion) to concentration levels below 0.5 ppb.
  • Major U.S. circuit board manufacturer uses KDF media for 94.4% of lead removal in the effluent water used to rinse off printed circuit boards. The water is now recycled in a closed-loop rinse-down system, which saves the company approximately $10,000 each year.

Carbon, or GAC (Granular Activated Charcoal)

GAC is very good at eliminating bad odors and tastes.  This will get rid of most contaminates but isn't as effective at removing sub-micron particles.  It's ideal as a post filter and doesn't remove minerals.  Often used in tandem with other systems. GAC mixed with catalytic carbon  will reduce over 99% of Chlorine, Chloramines and most (VOCS) Volatile organic compounds.
