3M™ AP2 Series Replacement Filter Cartridge, Model AP2-C401-G

We designed the 3M™ Replacement Filter Cartridge, Model AP2-C405-SG, 47-915401 to remove chlorine taste and odor, sediment, cysts, lead and select VOCs for point of use mains-fed water coolers and drinking water systems. It helps provide cleaner, clear, better tasting water. We also incorporate a scale inhibitor to help protect your equipment from failure due to lime scale build-up in hot water applications.

When faced with the challenge of providing the best possible quality water to enhance your brand, protect your machine and increase your profits, 3M rose to the occasion. Our water filtration filter systems provide ease of use and market leading protection for both your product and machine while producing cleaner, clearer water that is safe for food and beverage applications. Our graded carbon block filtration media filters sediment down to 1.0, 0.5, or 0.2 micron depending on model and also reduces 99.95% of protozoan cysts (Cryptosporidium and Giardia) along with 99.99% of bacteria. All materials are FDA CFR 21 compliant for food and drinking water safety and quality assurance.

Less Plastic, Less Waste, More Green
We added to our renowned range of AP2 water filters for mains-fed water coolers. Utilizing enhanced filtration technology, the new 3M AP2-G filters use 53 percent less plastic than the original AP2 range without compromising performance, making them a more compact and cost-effective choice for operators of cold water dispensing machines. By using less plastic in production, the filters reduce waste and represent an environmentally responsible source of clean, great tasting, quality drinking water.

Off the Scale!
We incorporate polyphosphates in the 3M™ Replacement Filter Cartridge, Model AP2-C405-SG, 47-915401 to bind calcium and magnesium hardness minerals, preventing them from precipitating out and building up on metallic surfaces. Siliphos is the key polyphosphate that in minute concentrations of 2-3 ppm, effectively prevents scale by inhibiting deposition of hardness minerals onto metallic surfaces. Siliphos also helps prevent corrosion by forming a thin protective layer on the metal surface.

The SQC Advantage
Our innovative Sanitary Quick Change (SQC™) design, an industry first for this application, allows for fast and easy cartridge change-outs without having to contact the filter media or the need for a filter wrench. The 3M™ High Flow SQC is one of the industry's most advanced water filtration system features, making change-outs fast – and with just a 1/4 turn to remove the old and replace the new, minimizes the possibility of leakage and contamination.

About Carbon Filtration
In many filtration applications, carbon is often the preferred media of choice to absorb impurities and one of the most powerful absorbents available. Carbon is highly effective due to the vast surface area contained within a small footprint. One pound of carbon contains a surface area of approximately 100 to 125 acres and can absorb an extremely wide range of chemicals. As effective as carbon is, activated carbon is even more effective. Activated carbon is carbon that has been electro-positively charged to create adsorption. Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process differs from absorption, where the fluid (absorbate) permeates or is dissolved and held within the filter media. When adsorption is in play, the water, or other fluid to be filtered, passes over the positively charged carbon surface. The negatively charged ions of the contaminants are attracted and held to the surface of the activated carbon particles and effectively removed.

Filters that employ activated carbon are rated by the size of the particles they can remove, as measured in microns. This nominal micron rating can range from 50 microns down to as small as 0.5, which is more than adequate to remove sediment, chlorine taste and odor, and most common bacteria from pre-filtered water.
