Steps for Replacing Refrigerator Filters

Remove the old water filter from your refrigerator. The filter might drip water, so place a towel under the filter assembly.

You release some filter styles by turning the attached knob or cap a quarter turn counterclockwise. When the cap is in a vertical position, pull to remove the filter. Slide the cap off the filter cartridge and put it in a safe place. You'll reuse it on your new filter.
If you have a push-button filter release, push the button while pulling on the water filter to remove it. To release the cap, turn it counterclockwise until it detaches from the filter. Set the cap aside in a safe place until you're ready to reuse it.
Some filters are enclosed in a cup or cover. Unscrew the cap or lower the cover and remove the filter.

To prevent spills, hold the filter in an upright position and use a towel to absorb any water.

Install the new filter.

For a quarter-turn cap, make sure the cap is in the vertical position. Slide it into the filter hole. Don't over-tighten the water filter. Turn the cap clockwise until it clicks into place.

For a push-button system, align the filter cap and insert it into the assembly. Once you insert the filter properly, the eject button will pop up.

For filters enclosed in a cup or cover, insert the filter into the filter assembly and replace the cup or cover.
