Haier CPN12XC9-E Air Filter
It is recommended that the filter that filters out particles from your home gets replaced every 90 days or so as to maintain good airflow in the home. The measurement proportions of the filter is not a personal choice but rather a requirement of your system. The filter can filter out dust and other fine particles from the air handler as well as the home.
How do you know if your main filter has a need to be replaced?
- Filter looks brown and crammed with dust very badly
- It is recommended to replace your air filter every season of the year in order to have cleaner breathable air inside
- As you face it toward a light source, it cannot shine through the dirt filled filter
