Frigidaire FRA122BU112 Filter
The air filter has the basic duty of trapping really small dust parts and other small elements as it passes through. 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 air you breathe. Because of the nature of filtering air, this filter should really be replaced or perhaps cleaned thoroughly a few times a year in order to keep things clean.
What signals that my primary air filter is not doing its job?
- The unit air filter looks brown and replacing it would be best before tomorrow
- When you face it toward a light, the light does not show on the other side a completely clogged filter
- It is highly advised to replace your air filter about every three months so as to have cleaner breathable air
