Mitsubishi MUY-D30NA Air Filter
It is suggested that the filter that filters out particles from your home is changed every 90 days or so as to maintain good airflow inside the house. Air Filters exist in many different filtering levels, which all depends on your personal desire for cleaner air and whether anyone suffers from allergies in the home. The actual dimensions of the air filter can not be a personal choice because of the constraint of whoever designed your heating and cooling system.
What are some indications that my main filter is about to stop working?
- If you hold it up to the light, it will barely shine through to the other side of a dirty filter
- Many pros have suggested to switch out the air filter in your unit every season of the year in order to have clean air running through the unit
- The system air filter looks gray or brown and it would be best to replace it ASAP
