It is often the first point of contact between your water supply and your home and is used as a pre-filtration unit before the water continues to reverse osmosis and activated carbon filters. It catches unwanted particles, including sand, dirt, silt, rust, and other fine particles as they attempt to enter your house’s water system. These particles and pollutants come from water sources, old and dirty pipes, as well as contaminants that are used to treat the water. The Big 20″ x 4.5″ filters are made of fine-melted polypropylene that are blown and spun into cylinder-like form. Removal of these particles allows filters, such as Carbon Block or GAC (Granular Activated Carbon) filters, as well as household water appliances like boilers, refrigerators, ice-makers, and many more, to perform better for longer periods of time. The Big water filter has wider dimensions than standard water filters, allowing it to process more water in less time for your house. A Big Sediment Water Filter removes the physical debris and impurities from your water. The sediment filter has tiny holes which water is able to pass, however the unwanted particles are not. As these particles come in different sizes, so do the filters. The filter sizes are measured in microns, the smaller the micron measurement, the smaller the holes in the filter, allowing to hold back the smallest of particles. Generally, for water that is more visibly polluted, containing larger particles, a sediment filter of a larger size is recommended in the first stage of installation to prevent the clogging of the next stage of filters. The main difference between a regular Sediment Filter and a Big Sediment Filter is the size, a Big Sediment Filter is usually used for filtering the water on the entrance into the house, appropriately called whole house filter. It is able to filter a larger volume of water than a regular filter with its larger surface area, size, and radius Outer Zone Mid Zone Inner Zone Innermost Zone Block Activated Coconut Shell Carbon Cartridge 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. The Big 20 x 4.5-inch Activated Carbon Block filters are made of fine coconut shell carbon. They remove odors, undesirable colors, and unpleasant tastes of many organic compounds. These filters also are effective in removing chemicals like iron, manganese, chlorine, and hydrogen sulfide from your water to name a few. By removing these unwanted byproducts, you can rest assured that you will have access to fresh and clean water. Since these filters are made of a finely packed carbon (forming a cylinder block), they offer a much finer filtration of suspended particles and dirt. The main difference between the regular Activated Carbon Block filter and the Big 20 x 4.5-inch Activated Carbon Block Filter is the size, a Big filter is usually used for filtering the water on the entrance into the house, appropriately called whole house filter. It is able to filter a larger volume of water than a regular filter with its larger surface area, larger size, and larger radius. Chlorine removal is what carbon is best at, and nothing else equals carbon’s ability to remove chlorine. What is Activated Carbon Block? There are many types of carbon. Most filter carbon is manufactured from coal, but other substances like wood and nut shells are also used. Coconut shell carbon is becoming popular not only because it is made from a renewable resource but also because it produces very good tasting water and is particularly good at trihalomethane removal. Besides the physical absorption that the Activated Carbon Block filter can provide, it also filters the water via a chemical process. The Activated Carbon Block filter is positively charged, thus it is able to attract negatively charged particles such as: chlorine, benzine, and other volatile organic compounds, and prevent them from flowing out into your glass. Carbon is well known for its unique absorbing ability; just a pound of carbon is able to provide up 125 acres of filtering surface area. Multi-Sage of Filtration Extraordinary Dirt-Holding Capacity Superior contaminant holding capacity and superior flow rate compared to similar size sediment water filter cartridges. These cartridges will reduce sediment particles as small as 5 microns without adding taste, odor, or color to your water. Such filter cartridges are ideal for all residential, rural, commercial, industrial, and municipal applications.
