Frigidaire LRA257ST211 Filter
A changeable air filter has the basic duty of removing small dust molecules and other miniscule particles as it passes through. This can both make the unit cleaner and make it work a lot better at doing its job while also filtering the dust out of the air you breathe all day. Because of the nature of filtering air, it should be swapped out for a new one or simply cleaned every so often depending on how much you use it.
What are some indications that my main filter is not working properly?
- It is greatly recommended to replace the filter every season of the year to help prevent bacteria from spreading too much
- The system air filter looks brown and probably should be replaced immediately
- When you face it toward a light, the light will hardly show on the other side a very dirty air filter
