Reverse Osmosis Filters

Types of Filters

   There are many types of RO Filters, that do a wide range of different filtration (Fluoride, Chlorine, Pesticides, Detergents and more). Some filters are designed to control the pH or adding certain minerals back into the water.  Multiple filters do make up the steps in the system but the membrane is the brains of the bunch. Solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules) to pass freely. 


Common Filters in a System

  • Inline Carbon
  • Pre Carbon
  • Post Carbon 
  • Membrane
  • Sediment Filter


Going through the Steps: 

  • Sediment filter to trap particles, including rust and calcium carbonate
  • Activated carbon filter to trap organic chemicals and chlorine, which will attack and degrade thin film composite membrane reverse osmosis membranes
  • Reverse Osmosis filter, which is a thin film composite membrane
  • Second carbon filter to capture those chemicals not removed by the reverse osmosis membrane


Things To Do To Maintain Your System

  1. Change filters regularly 
  2. Sanitize your system when needed
  3. Keeping the right pressure
  4. Staying up on seals/leaks
  5. Not Forgeting About It! :)
