Classwater Multistage Water Filtration System with KDF

Classwater offers a multi stage water filtration system designed for the removal of a variety of particulates, organic contaminants, heavy metals, bacteria, cysts, and parasites from incoming water.

All our Filtration systems include KDF a metallic alloy designed to enhance the effectiveness of the filtration system and prevent bacteria fouling of the water.


Our Standard Filtration System Includes

Pre-Filter (left) & Extruded Carbon/Heavy Metals Filter (right)

Our Pre-Filter at 1-micron
(1/1000 mm) has exceptional
dirt-holding capacity, designed to remove particulates such as sand, silt, unseen sludge, rust, asbestos, aluminum particles, or scale. The 1 micron removal rating assures quantitative retention of all parasite and cysts 1 micron and larger including Giardia and Cryptosporidium.

Our Extruded Carbon/Heavy Metals Filter at 0.5 micron
offers high levels of soluble and insoluble lead removal based upon the use of a powerful oxidizing filtration system. This filter reduces lead for at least 2500 gallons at 0.75 GPM (manufactured using FDA compliant and NSF approved materials, Standard 42 and 53 protocol). This filter will also reduce soluble iron manganese, aluminum, iron, mercury and hydrogen sulphide and offers a high reduction in the levels of Volatile Organic Compounds (VOCs) and meets NSF guidelines for VOCs reduction for over 500 gallons). It also removes chlorine/chloroamines, herbicides/pesticides, DDT, dioxins, solvents, fuels, PCBs, TCE, THMS, chlorinated hydrocarbons, hydrogen sulfate and particulates.

KDF Process Media are high-purity, granulated copper and zinc-based alloys that treat water through a process based upon the principle of redox (Oxidation-Reduction). They are included with all Classwater Filters.
Benefits of KDF® Process Media:

  • Maintain the integrity of water- improve water quality and taste- no fouling
  • Prevent bacteria from growing within filter compartment
  • Effectively removes chlorine and heavy metals and controls micro organism

All of our filtration systems are NSF (National Sanitation Foundation) Certified and Tested



Classwater has a solution for any size facility. Pictured to the left is one of our whole house filtration systems.







Bacteria Filters

For added peace of mind, or where the source water is not bacteriologically safe a special bacteria retentive filter (0.2 micron) can be added to the Classwater Standard Filtration System. This filter is designed for the removal of coliform and all other waterborne bacteria, cysts, and parasites (the 0.2 micron bacteria removal rating assures quantitative retention of all micro-organisms 0.2 microns and larger).


UV Filtration

Ultraviolet Light Filtration (UV) technology is used when there are microbiological, or bacterial, concerns. In this filtration technology, water is passed through a filter containing a lit ultraviolet light bulb emitting UV rays. UV light destroys and eliminates virtually all microbiological organisms that could possibly be found in the water supply. UV is extremely effective, and has been laboratory tested to remove 99.999% of the bacteria passing through it.

Reverse Osmosis Filtration Systems

Our Reverse Osmosis Filtration Systems combine pre and post filters with reverse osmosis technology. RO filters use a semi-permeable membrane to filter our all unwanted impurities. Only pure H2O molecules can pass the extremely tiny pores of the RO membrane. All other impurities, chemicals, chlorine, lead, minerals, cysts, parasites, cryptosporidium, and bacteria are flushed down the drain. Our Reverse Osmosis filtrations systems are available in 3, 4 and 5 stage configurations.

An easy way to picture how RO technology works is to imagine a drinking water glass with a piece of clear plastic wrap (the membrane) stretched across the top opening. Now imagine pushing water, under pressure, against the membrane and only the ultra-pure H2O molecules can get through the tiny pores, and the chemicals, are flushed down the drain. After a period of time the glass is full of only ultra-pure cool drinking water. RO filtration is a slower process and generally requires a holding tank to keep up with demand.
