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 Blue Activated Carbon Block Filter is the size, a Big Blue 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.
