Carrier 38GRQB09 Air Filter
It is advised that the filter is changed four times a year due to the filter clogging up and restricting the flow of air throughout the home. Air Filters are made in lots of styles and sizings, in which the one you choose will depend on your demands for clean air and the specific size of filter you need for your system. The actual dimensions of the filter is not a choice of options due to the constraint of the availability of room of your furnace or handler.
What warnings should I watch out for to know if my Carrier air filter is not working right?
- The system air filter looks gray or brown and it would be best to replace it soon
- If you were to lift up the filter, the light does not infiltrate to the opposite side of a dirty filter
- It is highly advised to replace the filter about every three months to help clean the indoor air
