Frigidaire FRA052XT722 Filter
The filter is good at trapping really small dust parts and other small elements from the air in the house. This can both help keep the wall unit from building up too much dust and make it work a lot better at doing its job while also cleaning the air in your home. During regular maintenance the unit filter must be replaced or perhaps washed periodically depending on how much you use it.
Key indicators that my main filter is not doing its job?
- The air filter looks very bad and it would be best to replace it immediately
- It is highly suggested to swap out your air filter every three months to help clean the indoor air
- As you face it toward a light source, it is unable to break through to the other side of the air filter
