Used For - Carbon filters remove sediment but they also remove chlorine, volatile organic compounds (VOCs), odors and unpleasant tastes from water. Carbon filters contain activated carbon, which is made through a special manufacturing process that creates more bonding sites. As water passes through a carbon filter, impurities like VOCs and heavy metals become chemically bonded to the carbon. As the water works its way through the filter, a lot of unwanted impurities will become stuck to the carbon bonding sites and the water will leave the filter much more pure than it came in. Carbon filters are effective at removing the impurities that bond to carbon. Not all impurities do. Sodium, for example, is able to pass directly through carbon filters without being removed. 2. Used For - Sediment filters are designed to remove suspended solids, which are also known as sediment, turbidity, or particulate. A sediment filter essentially functions like a net that catches unwanted dirt particles as your water flows through the system. A sediment filter is attached at the point where water comes into your home. The filter has a bed of natural media (sand, anthracite, etc.). As the water passes through this bed, unwanted dirt particles become trapped. The water moves into the filter and leaves the sediment behind, then out of the filter so you get water coming into your home that is free from particulate. Sediment filters are very common in many homes, Only sediment that will become trapped in the bed of natural media is removed. Trace pathogen elements, heavy metals, and volatile organic compounds can still remain in your water. However, in most cases, sediment filters do a good enough job to reduce the levels of unwanted particles to trace amounts which are deemed safe for drinking water. This means you can get drinkable, clean water with a sediment filter.
