LG ARNU073SER2 Air Filter
Filters are available in many varieties and specific sizes, depending on your desire for cleaner air and whether anyone suffers from allergies in the home. It is suggested the your furnace filter gets replaced every 3 months due to the filter clogging up and restricting the flow of air in the home. The actual size of the air filter can not be a choice that needs to be made but rather a requirement of the manufacturer of your system.
What are the clues to watch out for to know my air filter is about to go out?
- It is highly suggested to replace your air filter four times a year for clean air inside the house
- The main air filter appears filthy and stuffed with dirt badly
- If you were to lift up the filter, the light will hardly shine through the filter
