LG LMU180CE Air Filter
All air filters come in a wide array of varieties and specific sizes, which all depends on your personal choice for how clean you want the air and air handler requirements. The actual size of the filter is not a choice that needs to be made due to the constraint of the availability of room of the manufacturer of your system. Professionals in the industry advise that the filter is replaced for a clean one every 90 days or so to maintain the best air quality inside the house.
Hints your filter is in need of replacing
- It is suggested to swap out your air filter about every 90 days to keep the air fresh for the family
- When you face it toward a light, the light cannot penetrate through a clogged air filter
- It looks dirty and it would be best to replace it right now
