Carrier 48JZ Air Filter
Air Filters come in a wide array of filtering levels, depending on your air quality needs and air handler requirements. The size of the filter is not really a optional choice because it is based on the declared size of your furnace or handler. It is highly recommended that the air filter is changed four times a year for optimal air quality throughout the home.
Simple signals the air filter is on its last leg
- The filter looks like it is filled with dust and probably should be replaced right away
- It is highly recommended to switch out the air filter in your unit every three months to help keep the air fresh and make the unit run more efficient
- As you face it toward a light source, it does not shine through to the other side of a very dirty air filter
