LG LMU240HE Air Filter
It is recommended that the air filter is exchanged for a new one every 90 days or so as to maintain good airflow inside the house. The size of the air filter can not be a choice that needs to be made because of the constraint of your air handler. Filters for your LG LMU240HE exist in many different varieties and specific sizes, which depends on your particular demands for clean air and whether anyone suffers from allergies in the home.
Subtle cues of a declining filter
- Manufacturers have advised to switch out the air filter in your unit about every 90 days to help purify the air indoors
- The filter looks gross and replacing it would be best before tomorrow
- With a light behind the air filter, the light is unable to infiltrate to the opposite side of the dirt filled filter
