LG LAN121CNP Filter
A changeable air filter has the basic duty of filtering tiny dust fragments and other tiny particles from the inside air inside the home. This filtering system will help protect the unit and help it be way more efficiently while also cleaning the air breathe in and out everyday. Because it is really easy to do, the filter should be exchanged or simply cleaned at least twice a year if not more, depending on how much you use it.
Major indications of a weak primary air filter
- The unit air filter looks gross and perhaps should be replaced real soon
- With a light behind the air filter, the light is unable to infiltrate to the opposite side of the filter at all
- It is recommended to replace the filter every three months to help keep the air fresh and make the unit run more efficient
