Fujitsu AOU9RL2 Air Filter
It is recommended that the filter that filters out particles from your home gets replaced every 90 days or so because the filter can get clogged and may result in poor air flow in the home. The height, length and width of the filter is not really a optional choice due to the constraint of the availability of room of your HVAC blower system. All air filters come in a wide array of types and sizes, depending on your air quality needs and air handler size requirements.
Hints to watch for in a bad primary air filter
- With a light behind the air filter, the light cannot show through the dirt filled filter
- It is suggested to replace the filter every season of the year to help keep the air fresh and make the unit run more efficient
- Air filter looks brown and crammed with dust completely
