Frigidaire FRA104BU111 Filter
The unit filter has the basic duty of filtering minute dust particles and other particles from the inside air inside the home. The filter can both help keep the wall unit from building up too much dust and make it run much more efficient while also cleaning the air you breathe. Due to the amount of dust in the house, the filter should be simply replaced or possible scrubbed clean periodically depending on how much you use it.
What symptoms are present when the dust filter is almost full?
- When you hold it up, the light will not break through to the other side of a dirt-packed filter
- Manufacturers have recommended to replace the filter every three months to keep the unit running efficiently
- The unit air filter looks very bad and must be replaced now
