  • Take the new filter and keep turning its cap clockwise. 
  • Keep doing it till it goes back to its position. 
  • Once done, your filter will be fitted! 

Installing an In-Line Filter

To install this filter, you’ll need a copper cutter, a bucket, and steel wool.

  • Changing an in-line filter can be a little complicated due to its placement. 
  • Now, turn the cold-water supply of the refrigerator off. 
  • Find or create an area for tubing between the refrigerator and the shut-off valve. 
  • Now, use a plastic/copper cutter to cut the tubing. 
  • Make sure to cut it in squares as angled cuts may lead to leakage. 
  • If the edges are not smooth, use steel wool to smoothen them. 
  • Now, take this tubing and attach it to the new filter after removing its end cap. 
  • Lock it by putting the end cap back on the filter. 
  • Now, turn on the water supply. 
  • Hold the filter and let the water run till it is completely clear. 
  • You’ll have to repeat this process for both ends of the water filter. 
  • Don’t forget to keep an eye out for leaks. 

Installing a Push-In Filter

For this filter, you won’t require any tools. Hence, just get the new filter.

  • You’ll find a button next to the old filter. 
  • Push the button to eject the filter out of the refrigerator. 
  • Don’t forget to remove the cap, as you’ll use it on the new filter. 
  • Take the new filter & put the cap on it. Make it a point to place the cap evenly so that it lines up with your filter. 
  • Now, smoothly & carefully slide the new filter inside & your job will be perfectly done when the push-button pops up. 

Few Other Tips

  • Take a marker to write the date on the new filter. This will allow you to remember when it was fitted so that you can change it accordingly. 
  • It is recommended to change the water filter once every six months. 
  • Don’t forget to run 2 to 3 gallons of water through the new filter before you start using it. This will ensure that all that impurities get cleared. 


Now that you know how to install the water filter inside your refrigerator, you should be able to go through the complete process conveniently and without the help of any professionals.
