LG LP120HED Air Filter
Filters for your LG LP120HED come in many types and sizes, which all depends on your personal demands for clean air and whether anyone suffers from allergies in the home. The size of the filter is not a choice you make because it is based on the declared size of the manufacturer of your system. It is highly recommended that the air filter gets replaced every 90 days or so due to the filter clogging up and restricting the flow of air through the ducts.
Major warnings the primary air filter will soon need to be replaced
- Filter appears grimy and packed with dust very badly
- Professionals have advised to switch out the air filter in your unit every season of the year for clean air inside the house
- With a light behind the air filter, the light will not shine on the opposite side of the filter
