What is the difference between reverse osmosis and normal water filters?
How do reverse osmosis systems differ from other water filters? We get asked this question frequently and would like to answer it in our blog post.
Reverse osmosis systems are no ordinary water filter systems; reverse osmosis filters filter far more out of tap water than pure water filters. Most water filters are usually just a carbon-based filter or a sediment filter. A sediment filter is usually made of spun polyamide or cotton (as well as a few less common fibers) and is designed to remove most sediment from the water, but does not filter out any chemicals and does not affect the taste of the water. Carbon filters use positively charged or “activated” carbon to remove negatively charged contaminants, such as certain chemicals and volatile organic compounds. However, the reverse osmosis system has both sediment and carbon filters and a semi-permeable membrane. This membrane distinguishes the reverse osmosis system from other systems as it enables reverse osmosis in the first place.
The reverse osmosis process allows your system to filter out not only visible solids (as with traditional water filters), but also dissolved substances! This means that reverse osmosis removes more than 90% of all pollutants and contaminants in your water, including toxins such as arsenic. Reverse osmosis is achieved by the water pressure in the household forcing tap water through the system's filters, then through the semi-permeable membrane and then through the filters again. The result is clean water without sheep and improved taste. Because of this result, many chefs and breweries use reverse osmosis water for cooking and brewing.
To keep your reverse osmosis system and any other water filtration system running smoothly, you should change the filters regularly! Manufacturers recommend replacing the pre- and post-filters every six to twelve months and the membrane every 2 to 5 years. RO filters must be replaced because they are constantly submerged in water and absorb pollutants. After six months, bacteria can grow in the filter medium in RO filters. As soon as the filters are too full (usually between 6 and 12 months), the pollutants that have already been collected could get back into your drinking water. Not only does this ruin your membrane, but it can also have negative health effects. The most important thing is to have your filters replaced regularly so that you can enjoy fresh and pure drinking water at any time.
