LG ARNU093SER2 Air Filter
Professionals in the industry advise that the air filter is exchanged for a new one every 3 months for optimal air quality in the home. The filter may filter out dust and other fine particles from the air handler. Exact measurements of the filter is not a choice you make but rather a requirement of your air handler.
Some warnings the dust filter needs replacing
- If you hold it up to the light, it does not shine through the filter at all
- Manufacturers have recommended to switch out the air filter in your unit four times a year to help clean the indoor air
- The main filter looks dusty and replacing it would be best right away
