Whirlpool ATR0945RPP0 Air Filter
HVAC specialists suggest that the filter is replaced for a clean one every 90 days or so due to the filter clogging up and restricting the flow of air inside the house. All air filters come in many styles and sizings, which all depends on your personal air quality needs and air handler size requirements. The actual dimensions of the filter is not a optional choice because of the constraint of the manufacturer of your system.
Simple indications of a poorly working primary air filter
- If you place a light source behind it, the light does not shine on the opposite side of a very dirty air filter
- It is highly advised to replace the filter about every 90 days in order to have cleaner breathable air inside
- The filter looks very bad and must be replaced as soon as humanly possible
