Is a Reverse Osmosis Water Filter the Best Way For You to Go?

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.

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 water filtration systems.

Reverse osmosis water filter systems

Reverse osmosis water filter systems Manufacturers and marketers have overstated the usefulness of reverse osmosis water filter systems for home use. As a primary or secondary stage treatment in a large plant or facility this process is useful, but even then it does not meet the somewhat lax government standards for public drinking water. It still has a long way to go before being clean enough to be called safe drinking water. Tap water contains over 2000 known carcinogens.

Filtering water by reverse osmosis blocks only a small number of these. Reverse osmosis relies on a porous membrane through which water is forced at high pressure. Depending on the size of the pores, some chemicals are blocked while other pass through. When a chemical is dissolved in water, most of the resulting molecular sizes are smaller than the size of the water. It stands to reason that if the water is able to pass through the membrane, the majority of the chemicals dissolved in it will go right through as well.
