LG LWP1820PEL Filter
The filter is the best line of defense when filtering minute dust particles and other miniscule particles from the air in the house. This can both keep the unit clean and make it run more efficient while cleaning the air breathe in and out everyday. Because of the nature of filtering air, the unit filter must be changed out or simply cleaned periodically in order to keep things clean.
Indications of an ailing air filter
- The system filter looks brown and the best thing to do would be to replace it as soon as you can
- Manufacturers have advised to replace your air filter every 90 days to help prevent bacteria from spreading too much
- If you place a light source behind it, the light will almost not show through the filter at all
