Domestic Water Filters

Water filtration acts like a sieve to remove unwanted particles from the water. The two most common water filtration systems are sediment filters and activated carbon filters. The two are often combined. Sediment filters generally remove contaminants according to size. They remove many microscopic contaminants, but some, such as viruses, dissolved pharmaceuticals, and some unwanted minerals are too small to be trapped, and these pass through instead. Most filtration systems use activated carbon to filter out contaminants, which is very effective. Carbon filters trap any carbon-based particles that pass through them. Carbon-based particles account for the majority of the harmful contaminants that are present in most water.
