While you’ve almost certainly seen “RO”during your water filter search, do you really know what it is or how it works? In a nutshell, “RO” or Reverse osmosis water purification systems are the most advanced in-home water purification systems available on the market. No other home water treatment system can offer you as much protection and reliability.

Reverse osmosis systems work by pushing water through a semi-permeable membrane, which acts as an extremely fine filter – blocking any particles that are larger than water molecules. This process filters many things a carbon filter may miss, including perchlorate, sulfates, fluoride, industrial chemicals, heavy metals (including lead), chlorine, chlorides which make water taste salty, and pharmaceuticals. Reverse osmosis filters are also the only type certified to remove arsenic, but they must be periodically sanitized with bleach and, eventually, the entire romembrane must be replaced. WaterFilterShop.co.uk also has a wide range of reverse osmosis systems with an attached alkaline filter. This attachment adds beneficial minerals and ionizes your drinking water for better taste and health with fewer contaminants than any other filter.

While the quality of the water supplied is perhaps the highest quality water you can get anywhere, the relative complexity of most systems require a plumber to get them set up and running. However once installed, replacing the filter is as simple as a twist and click – no tools required. If you don't want to install, choose our latest model, the Puricom ZIP(ZeroInstallation Purifier).
