Reverse Osmosis Water Filters

Reverse osmosis water filters are the home water filters of choice for removing as many contaminants as possible. Reverse osmosis is the only water filtration system that will eliminate salt from your drinking water. It has become very popular and for good reason. Reverse osmosis ensures that your drinking water is safe and clean. Read below to find out how reverse osmosis works, what pollutants it will remove and the benefits and disadvantages of reverse osmosis water filters.

What do reverse osmosis water filters remove?

A complete reverse osmosis system that includes a prefilter and a postfilter will get rid of lead, arsenic, copper, chlorine, cadmium, giardia, pesticides, salt, trihalomethanes, sulfates, cysts, nitrates, as well as some bacteria and viruses.

How do reverse osmosis water filters work?

Most units will have a prefilter that the water goes through first which strains out sediment. From there the water goes through a cellophane like membrane that filters out even smaller pollutants. Before the water comes out of the special faucet mounted on your sink, the water goes through one last carbon filter that removes any chemicals picked up along the way.

Benefits of reverse osmosis water filters:

• Convenience of clean water right out of the tap, good for drinking and cooking with.
• Whole house systems available.
• One of the most highly effective water filtration systems which delivers clean, safe water to drink.
• Fairly economical.

Disadvantages of reverse osmosis water filters:

• Plumbing work is required.
• Initial cost can be expensive.

Considering both the advantages and the disadvantages of reverse osmosis water filters, you can make a decision as to whether it is the right water filtration system for you. There are many other water filtration systems, but reverse osmosis will have your water the cleanest by removing the most amount of pollutants.
