The unit filter is there for removing microscopic dust and other tiny particles as it is being forced through the system. This helps make the unit cleaner and make it run much more efficient while cleaning the air you breathe in your house. Because of this, the filter should be replaced or perhaps washed every so often in order to keep things clean.
Subtle hints the primary air filter is in need of replacing
- Filter appears dirty and packed with dust very badly
- When you face it toward a light, the light will barely show through a clogged air filter
- It is highly suggested to swap out your air filter every 90 days in order to have clean air in the home
