LG LP120HEM Filter
A changeable air filter was created for filtering out dust and other unwanted bits as it is being forced through the system. This helps keep the unit dust-free and help it be way more efficiently while, at the same time, filtering the air breathe in and out everyday. Because it is really easy to do, the unit filter must be swapped out for a new one or cleaned a few times a year in order to keep things clean.
Indications the primary air filter is in dire straights
- Manufacturers have advised to switch out the air filter in your unit every 90 days so as to have cleaner breathable air
- When you hold it up, the light will barely penetrate through the dirt filled filter
- The main filter looks dirty and probably should be replaced immediately
