LG LW5012 Filter
The filter in the wall unit is responsible for filtering out dust and other small elements as it passes through. This helps make the unit cleaner and make it work more efficient while also filtering the air breathe in and out everyday. Due to the amount of dust in the house, the unit filter must be replaced or simply cleaned at least twice a year if not more, in order to keep things clean.
Red flags your main filter is in dire straights
- The air filter looks bad and maybe should be replaced right away
- When you face it toward a light, the light cannot penetrate through the filter
- Many pros have advised to switch out the air filter in your unit four times a year to help keep the air fresh and make the unit run more efficient
