STANDARD SIZED FLUORIDE/ARSENIC FILTER. CARBON BLOCK FILTER

 If you are replacing the filters on your system, you can upgrade it with this simple addition. This is for the Dual Under Sink Filter System. If you want to remove Fluoride/Arsenic, use our Activated Alumina filter, followed by the Carbon Block filter.


Fluoride/Arsenic is not normally removed through the filtration process. It can be removed through reverse osmosis, this filter is designed to remove the fluoride through filtration using Activated Alumina. Activated alumina (AA) is the only filter material specifically designed to remove fluoride and arsenic from water. A ceramic compound made of aluminum oxide with a very high surface-area-to-weight ratio, AA has a very high capacity for fluoride adsorption. Most municipal water supplies add 2 ppm (parts per million) of fluoride. AA filters can reduce fluoride concentrations to below .1 ppm, or down to 99% of the normal fluoridated water level. Arsenic is a concern if you are living in an agricultural area. If you are concerned about these contaminants in your water supply, this is the ideal low cost system for you.

With carbon block filters, water is forced through the pores of the densely compacted carbon block, where a combination of mechanical filtration, electrokinetic adsorption, and physical/ chemical adsorption take place to reduce a wide range of contaminants. Solid Carbon Block technology can reduce chlorine, taste and odor problems, particulate matter, and a wide range of contaminants of health concern -- cysts (cryptosporidium and giardia), VOCs (pesticides, herbicides, and chemicals), certain endocrine disrupters, Trihalomethanes (cancer-causing disinfection by-products), heavy metals (lead, mercury), turbidity, MTBE, Chloramines and asbestos. Solid carbon block filters do not remove healthful, naturally-occurring minerals, require no electricity, and do not add salt or silver to the water.
