Best Reverse Osmosis Filter: Whirlpool High Capacity Reverse Osmosis System Water Filter Model: WHER25

Who Needs It?

Reverse Osmosis is recommended to be used only for specific contamination problems that other filters can't remove. For example, nitrates or arsenic. Reverse Osmosis is the only kind of filter that will remove them. Most water doesn't have an issue with these contaminates. However, if your water has unusual contaminates like these, this is the way to go. It used to be that Reverse Osmosis filters were much more popular, before carbon filters were perfected. Now, because of the slowness of the reverse osmosis process and because of the huge waste of water, reverse osmosis filters are used much less.

Its Claim to Being "Best"

ConsumerSearch.com has made a rather exhaustive review of 30 different reviews and then compiled their results. They recommend this model because it is less expensive than other systems but "performs almost identically" to more expensive units. They don't recommend reverse osmosis to most people because of the waste of water, though it does remove a wide range of contaminants.

Its Disadvantages

There are a number of disadvantages to the reverse osmosis process. It normally wastes 5 gallons of water for every 1 gallon purified. Then too,it flushes the contaminants back into the water supply. The process is slow. This particular model will give you 14.53 gallons of filtered water per day. It requires professional installation for $200.00 to $300.00 a unit.
