How to Sanitize a GE Water Filter

A water filtration system helps reduce the presence of minerals, sediment and unpleasant taste in your water. GE makes a variety of water filtration systems, and while maintenance on any type of water filter is important to keep it at peak performance, periodic sanitizing is important if you own the GE osmosis water filter system. Sanitizing your water filter ensures that your system is clean, functioning properly and producing water that's safe to drink.

  Turn on the water faucet and leave the water running for three or four minutes, or until the tank is completely drained. Once the tank is empty, turn off the faucet.

  Bleach kills germs and bacteria, effectively sanitizing your filter.
  
  Fill one of the three canisters labeled as a "Sanitization Canister" with water until the water is 1 inch below the top. Add 1 ounce of household bleach to the canister.

  Place the sanitizing canister in the position reserved for the prefilter canister. Rotate the sanitizing canister to the right one-third of a turn until it snaps into place and the alignment marks meet up.

  Install the other two canisters marked for sanitization into position where the reverse osmosis and postfilter canisters go. Lock them into position by turning them one-third of a turn toward the right.

  Turn on your water supply. Run water from the faucet until it begins to flow. Turn the water faucet off and wait 10 minutes for the water filter system to fill.

  Run the water faucet for 20 minutes to remove the smell of bleach.

  Turn off the water supply to the filter system again. Run the faucet for 10 to 20 seconds to drain the water filter system.

  Rotate each individual sanitization canister one-third of a turn to the left. Remove them from the filter system. Set them on a clean kitchen towel in an upside-down position to air dry. Store them until the next use.
