A changeable air filter has the basic duty of filtering tiny dust fragments and other small elements as it is being forced through the system. This can both keep the unit clean and help it be more efficient while also cleaning the dust out of the air you breathe all day. Because of the nature of filtering air, it should be changed out or cleaned a few times a year depending on how much you use it.
General indicators that your filter probably needs to be replaced
- If you hold it up to the light, it will almost not shine through to the other side of a dirt-packed filter
- It looks dusty and should be replaced real soon
- Many pros have suggested to replace the filter about every three months in order for the machine to run more efficient and to breathe easier inside
