On your Lennox HVAC unit, the filter cabinet is located next to the air handler or furnace. Open the filter cabinet’s panel and remove it. Remove the existing filter and insert the new filter, following the direction of the arrows printed on the unit.
In most homes, the furnace and air handler are located in a utility closet, garage, or basement – the attic may also be an option for HVAC equipment installation. In order to change the filter, you’ll need to locate the filter cabinet. The filter cabinet is typically located between the return air duct and the air handler or furnace.
Once you have located the filter cabinet, remove the metal access door on the face of the cabinet, and set it aside. Remove the existing filter using the cardboard tabs on the face of the filter. The old filter should slide out easily. Dispose of the old filter.
Unwrap your new air filter and insert it into the filter cabinet. Make sure the airflow arrow printed on the new filter is pointing in the direction of the furnace or air handler. Once the filter is in position, replace the filter cabinet door securely.
The Lennox X6672 filter used in the HCC16-28 Y2920 air filter cabinet has a service life of 9 to 12 months. This filter has a MERV rating of 16 for superior contaminant control in your home or business.
After installing your new filter, set a reminder for yourself to check the filter in 9 months. If you check your filter at this point in time and it is not ready to be changed, reinsert it and shut the filter cabinet door securely, and set another reminder to change the filter in 3 more months.
Changing the air filter in your Lennox X6672 unit is easy to do and will take you less than 5 minutes to complete.
A furnace filter is a disposable (or in some cases washable) HVAC system component that is designed to be replaced at certain intervals. If you don’t replace it, it will not be able to do an effective job of removing contaminants. Here’s why you should change it regularly:
