Panasonic CU-KS18NKU Air Filter
HVAC specialists suggest that the filter that filters out particles from your home is replaced for a clean one every 90 days or so due to the filter clogging up and restricting the flow of air in the home. Measurements of the filter is not really a personal choice because it is based on the declared size of your HVAC blower system. The main filter should filter bad things in the air and other fine particles from the air handler.
What are some indications that my filter is not working properly?
- The system air filter looks brown and could be replaced soon
- Professionals have suggested to replace your air filter four times a year in order for the machine to run more efficient and to breathe easier inside
- As you face it toward a light source, it will almost not show through the filter at all
