LG LAU121HNM Filter
The filter was created for trapping really small dust parts and other small elements as it is being forced through the system. This simple filter can make the unit cleaner and make it operate way more efficiently while, at the same time, filtering the air you breathe. During regular maintenance the filter should be changed out or cleaned a few times a year depending on how much you use it.
Major symptoms your main filter is not going to last much longer
- Many pros have recommended to swap out your air filter four times a year to help prevent bacteria from spreading too much
- The main filter looks gray or brown and it would be best to replace it immediately
- If you lift the air filter up to a source of bright light, the light will barely break through to the other side of the filter
