Friedrich MR09Y3H Air Filter
It is recommended that the filter is exchanged for a new one four times a year because the filter can get clogged and may result in poor air flow through the ducts. Air Filters come in a wide array of varieties and specific sizes, depending on your choice for how clean you want the air and air handler size requirements. Exact measurements of the air filter can not be a choice you make because of the constraint of your air handler.
Clues your Friedrich air filter will have to be replaced
- It is highly recommended to swap out your air filter about every 90 days in order to have clean air in the home
- The system air filter looks very bad and probably should be replaced now
- If you place a light source behind it, the light is unable to infiltrate to the opposite side of a dirt-packed filter
