Key advantages of reverse osmosis water systems

  • they employ semi-permeable membranes that can remove molecular compounds smaller in size than water molecules. In practice this means they can remove up to 99% of contaminants. They can have up to 6 filtration stages designed to do everything from improving taste to removing contaminants and sediment.
  • they have a longer filter life than most other filters. Filter cartridges generally require replacing every 6-12 months, whereas a pitcher or faucet filter require replacement filter cartridges much more frequently.
Cheap reverse osmosis systems generally employ lower quality components, so, whilst the design and components may look similar across products, it’s the quality of those components and the number of stages of filtration that are the key factors to consider, or water quality and life of the filter can be affected. See the article on ‘What is a Reverse Osmosis Water Filter System?’ for a general introduction to reverse osmosis water filtration systems.
