How Reverse Osmosis Water Filters Keep Your Water Clean

A reverse osmosis water filter works by allowing water to pass through a thin membrane that does not allow other materials to pass. This means you wind up with clean, pure water on the using side of the membrane, while heavy metals, biological contaminants, and even chlorine remain on the other side of the membrane, filtering out and eventually flushed from the water filter's system. A reverse osmosis water filter eliminates almost all of several contaminants from your drinking water: arsenic, chlorine, fluoride, heavy metals, nitrates, sediments, iron, bacteria, viruses, bad tastes and odors, and some of your hydrogen sulfide and VOCs (an example: pesticides).

That's because it is so very effective at removing contaminants from your water supply. It works by moving your water through a series of reservoirs, in which the clean water moves to the clean side of the filter, leaving behind the contaminants. The filter does not work through pressure; instead, water must move passively. This means that the filtration process is slower than you might find in other...

The Information You Need About Reverse Osmosis Water Filters

Reverse osmosis water filters function by passing water through a membrane-type filter that leaves impurities on the other side. Clean water is deposited in a reservoir, to be pumped up to a separate drinking water faucet, and the contaminants on the other side are flushed out of the system later. This type of water filter is among the best ways to clean your water, and it will remove most contaminants: most bacteria and viruses, pesticides and other VOCs, hydrogen sulfide, nitrates, sediments, arsenic, chlorine, fluoride, heavy metals like lead and mercury, iron, and even bad tastes.

Some call a reverse osmosis water filter a hyperfiltration system because it's so good at eliminating contaminants. When water goes through a standard reverse osmosis water filter, water from your supply will move through several reservoirs. The filter allows clean water to move to the clean water side of the system and leaves contaminants behind to be washed away later. It is a passive system - that is, water is not moved through with pressure but rather via a chemical process called osmosis. It's a very slow but very thorough filtration system, and will produce about 15 gallons a day of bottled-quality water, which...
