LG ARNU093TJC2 Air Filter
HVAC specialists suggest that the filter is swapped out every 90 days or so due to the filter clogging up and restricting the flow of air in the home. All air filters are available in many varieties and specific sizes, depending on your desire for cleaner air and the specific size of filter you need for your system. Exact measurements of the filter is not a choice that needs to be made due to the constraint of the availability of room of your furnace or handler.
Some clues of an inadequate main filter
- The air filter looks dusty and maybe should be replaced before tomorrow
- When you hold it up, the light will almost not break through to the other side of the filter
- It is highly recommended to swap out your air filter about every three months to keep the unit running efficiently
