The air filter has the main responsibility for trapping really small dust parts and other tiny bits from the air in the house. This simple filter can help keep the wall unit from building up too much dust and make it operate way more efficiently while also cleaning the dust out of the air you breathe all day. Due to the fact that this is an important part of the system, the filter should be replaced or possible scrubbed clean a few times a year in order to keep things clean.
What warnings are present when my dust filter is in need of replacing?
- It is recommended to switch out the air filter in your unit every three months to keep the unit running efficiently
- As you face it toward a light source, it cannot penetrate through the air filter
- The unit air filter looks brown and should be replaced as soon as you can
