Frigidaire FRA296ST21 Filter
The filter was designed for trapping really small dust parts and other particles as it passes through. This filtering system will help keep the wall unit from building up too much dust and make it run much more efficient while also filtering the air you breathe in your house. Because of this, the filter should be swapped out for a new one or cleaned periodically depending on how much you use it.
What signals that my main filter has to be replaced?
- It is highly advised to replace the filter every three months for clean air inside the house
- Sunlight will not breach the other side of the air filter
- The system air filter looks dusty and probably should be replaced as soon as you can
