This 3 Stage Large Big Blue 4.5x20' filters come mounted on a sturdy metal bracket for easy installation. It's a 1' NPT connection. There are 3 filters included.
All of our sediment filters use multi-gradient spun polypropylene filter cartridges. These cartridges use the entire depth of their media by trapping the largest sediment particles on the outside of the filter, then gradually stepping down the size of particles they will reject as the water moves closer to the core of the filter. The result is longer filter life, greater dirt-holding capacity, higher flow rates, and remarkably low pressure drop. The 100% pure polypropylene media is highly resistant to bacteria and chemicals, making this an excellent choice for both well water and municipal water treatment applications.
GAC and Carbon Block Filters.
Carbon removes/reduces many volatile organic chemicals (VOC), pesticides and herbicides, as well as chlorine, benzene, trihalomethane (THM) compounds, radon, solvents and hundreds of other man-made chemicals found in tap water. Some activated carbon filters are moderately effective at removing some, but not all, heavy metals. In addition, densely compacted carbon block filters mechanically remove particles down to 0.5 micron, including Giardia and Cryptosporidium, turbidity and particulates. Although some iron, manganese, and hydrogen sulfide will be removed by a carbon block filter, if they are present at higher levels the effectiveness of carbon filter against iron and manganese is generally short-lived, you should consider a system with KDF.
Granular Activated Carbon does not remove sediment / particulate material very well, so they are often preceded by a sediment filter. Sediment pre-filters also prolong the activate carbon cartridge life by eliminating gross contaminants that would otherwise clog the activated carbon thereby reducing the surface area available for absorption. Carbon block filters are generally better then GAC filters at removing sediment. All our three stage system comes with a sediment filter, a granular activated carbon, followed by a carbon block filter.
