Product review (5 stars): Clear the air line
This is easy to install and a good replacement. There will be air coming from the line for the first couple of glasses of water you get from your fridge dispenser. After installing you can clear the air line just by getting water from your dispenser.  It will sputter and splash a little, just know that it's normal until the air clears.  We also write the date with a marker on the filter so we'll remember to change it.
