Reverse osmosis filters are quickly becoming a thing of the past as more and more studies point to the health risks of de-mineralized water. Although once very popular due to clever marketing, they are no longer considered the best choice when it comes to water filtration. A reverse osmosis filter works by exposing water under pressure to a semi-permeable membrane with ultra-fine pores. Due to the fact that most inorganic contaminants are molcecularly larger in size than water, only a portion of the water passes through, without the inorganic compounds or trace minerals. However, there are many chemicals that are smaller than the water molecule, so a carbon filter must be used as well to address these toxins. Why aren't reverse osmosis filters the best option? There are a number of reasons why you are better off with a multi-stage filter rather than a RO system. Here they are in a nutshell: - These systems waste about 2-3 gallons of water for every gallon they produce.
- Usage cost is about 18-24 cents per gallon, as opposed to 10 cents for a multi-stage unit.
- Reverse osmosis filters remove essential trace elements such as calcium, potassium and magnesium, which can be harmful to your health.
- Compared to other options, reverse osmosis water filtration is the least efficient and requires the most maintenance.
