What is a Reverse Osmosis Water Filter?
Those who are concerned about pure water, and want to have a constant source of water free from contaminants may wish to install a reverse osmosis water filter. Reverse osmosis is also known as hyper-filtration, and is the most thorough type of filtration available. Although water filtration is the most common usage, reverse osmosis is also used to purify other liquids such as ethanol and glycol. The reverse osmosis water filter can remove particles as small as dissolved ions from the water supply. It stops virtually every contaminant. Typically, there are at least three stages in a reverse osmosis filter. Water is first forced through a small prefilter, which strains out sediment, and then it is passed through a membrane to screen out smaller contaminants. The last phase is a carbon filter. Between these three elements, the reverse osmosis water filter will eliminate a wide variety of contaminants, including minerals, bacteria and viruses, and provide a constant supply of fresh, clean
A reverse osmosis water filter is a type of water filter that is used when there is concern about a wide range of contaminant in drinking water. It uses a mechanical process and so does not require electricity or any other power source. The system removes about everything including strips of lead, arsenic, cadmium, copper, giardia, chlorine, salt, pesticides, sulfates, nitrates, and cysts of worms, if any. The device propels water into a prefilter where sediments are trapped.
