To get the most benefit from the water filter built into your refrigerator (on refrigerator models that include water filtration for icemakers and/or chilled water dispensers), you should change the water filter cartridge on a regular basis. Most manufacturers recommend that you change your refrigerator water filter every six months in typical conditions. Some brands may recommend more frequent replacement of filter cartridges for heavier use. This insures that the filter is doing its best to remove chemicals, particulates and bacteria, along with any off tastes, from your ice and chilled drinking water.
Changing your refrigerator water filter is easy. All refrigerator water filter cartridges include easy to follow installation instructions. You can find the correct model number/part number for the water filter cartridge for your brand and model refrigerator by looking in the instruction manual that came with your refrigerator. Be sure to purchase the correct brand and model filter cartridge for your refrigerator.
In general, most refrigerator water filters are easy to remove. A quarter-turn to the left is all that is needed to unlock most filters. The old filter cartridge can be removed from the water filter housing. Then, the new filter cartridge can be inserted into position in the water filter housing. A quarter-turn to the right will lock the new filter cartridge into the filter housing.
Be sure to flush two or more gallons of water through the new filter as soon as it is installed and discard that water. Most refrigerator water filters use activated charcoal (or other carbon filtration) and some loose carbon or activated charcoal particles will be 雪櫃消委會 present in the first gallon or two of water that passes through the new filter. Flushing these particles out of the filter before use will insure that your water and/or ice will have no unwanted residue or off taste.
Some brands/models may have filters located in their base grilles. Some of these types of filter cartridges may have reusable knobs that must be removed from the old cartridge and installed on the new cartridge before the new cartridge is inserted in the filter housing. Some refrigerators may use push button cartridges in their base grilles that pop out at the push of a button so that they can be fully grasped in order to be removed. This type of cartridge may use a cap that must be removed from the old cartridge and mounted on the new cartridge before the new cartridge is installed. Other refrigerators may have cartridges that are accessed from inside their refrigerator compartments, and some may have cartridges and housings that are covered by a plastic housing/access panel that must be removed with a wrench or by turning a knob to gain access to the cartridge.
