What is an in-line water filter?

An inline water filter is a type of water filter, which, instead of being a separate water filter, is attached to an already existing space where there is water flow. This offer is mostly inserted in the middle of the path of the water flow.

Why does an inline water filter work well in a refrigerator?

  • When you attach an inline water filter inside a refrigerator, it forces the water flow to become clearer and cleaner than what it otherwise will be. The inline water filter makes the water flow through activated carbon that is present inside the filter. As a result, it helps in removing any traces of contaminants that may still be present.

Is it easy to change a used up inline filter in a refrigerator?

Here are a few easy steps that will help you change a used up inline water filter in a refrigerator:

  • Now make sure to turn off the water supply so that there is no water leakage.
  • Cut off the tubes at both ends of the filter.
  • Take the new filter and remove (if any) washer rings at the end of both sides of the tube.
  • Now insert the tube in the opening of the filter on the side.
  • Run this into a bucket so that any dirt and contaminants can flush out.
  • Once done, insert the other end of the tube into the open end of the filter.

Make sure to push the plastic tube as far as it will go inside the filter, so that it fits in tightly.
