The filter is the best line of defense when removing small dust molecules and other small elements from the inside air inside the home. This simple filter can keep the unit clean and make it operate a lot better at doing its job while cleaning the dust out of the air you breathe all day. Due to the fact that this is an important part of the system, it should be changed out or perhaps washed periodically in order to keep things clean.
Easy warnings of a faulty primary air filter
- If you lift the air filter up to a source of bright light, the light will hardly shine on the opposite side of the filter
- Manufacturers have recommended to replace the filter four times a year in order to have clean air in the home
- The air filter looks dirty and perhaps should be replaced real soon
