Video Below! Just for a comparison on what a clean furnace filter will look like vs a dirty one. This is our dirty one (on left!). Nice and black. This is what typically a one month old furnace filter will look like. Especially if you have kids and animals.  

Vs. The nice bright, white and shiny (on the right!). This is what a new furnace filter should look like.  When you start to see it look like this, that means that the system is really struggling for airflow, and it’s time to get it changed.
