Reverse Osmosis Water Filters
Reverse Osmosis Water Filters Removes Smallest Bacteria
When you are looking to reduce the threat of contaminants in your drinking water, a reverse osmosis water filtration system is known as one of the best.
Originally developed to remove salt from seawater for the U.S. government in the 1950s, and used extensively on submarines and Navy ships, a reverse osmosis water filter does not use any chemicals such as chlorine or iodine and does not require frequent filter changes or cleaning.
The secret behind the reverse osmosis water purifier is the size of its filtering ability. The human hair is about 1 micron, however disease causing bacteria is much smaller, typically between about .01 and .001 micron. A reverse osmosis water purifier utilizes layers of membranes, rolled into a cylinder with effective filtering to .0001 microns.
Filtration through a reverse osmosis water purifier is not as fast as other filters due to the size of membranes. For home use, usually fifty to sixty gallons of water per day is needed and achieving that capacity depends on the length and number of the membrane sheets within the filter. Typically a larger quantity of shorter membranes allow water to pass through more quickly while fewer sheets of longer membranes may still increase the time it take to filter the water.

Pressure & Flow
Some of the other factors affecting the rate at which water will flow are temperature and pressure pushing it through the reverse osmosis water filter. Typical industry recommendations are for a water pressure of 50 pounds per square inch at 77 degrees Fahrenheit. Since most home water supplies will vary widely , reputable reverse osmosis water purifier suppliers will not guarantee a specific amount of water that will be available daily.
Another advantage of a reverse osmosis water purifier is the life of the membrane filters. Other types of water filtration systems require a new filter between two and four weeks, depending on the type and density of the impurities in the water. Most reverse osmosis water filter systems have the unique self-cleaning ability that uses raw unfiltered water to rinse over the membranes, sending the impurities right back where they came from.
