Goodman GCH91155DX Air Filter
Filters are made in lots of styles and sizings, depending on your air quality needs and the specific size of filter you need for your system. It is recommended that the air filter is changed four times a year due to the filter clogging up and restricting the flow of air throughout the home. Exact measurements of the whole house filter optional choice but rather a requirement of your system.
What signals that my Goodman air filter is about to stop working?
- It is highly advised to replace the filter every 90 days to keep the unit running efficiently
- It looks bad and perhaps should be replaced immediately
- When you hold the filter up to the light, it cannot penetrate through a very dirty air filter
