Heat Controller B-VMH09FC-1 Air Filter
It is suggested that the air filter gets replaced every 90 days or so because the filter can get clogged and may result in poor air flow in the home. All air filters are available in many filtering levels, depending on your choice for how clean you want the air and the specific size of filter you need for your system. The actual size of the filter is not really a personal choice but rather a requirement of whoever designed your heating and cooling system.
How can I tell if my primary air filter is not well?
- It is highly recommended to swap out your air filter about every three months to keep the house clean and less dusty
- The system air filter looks gross and maybe should be replaced soon
- As you face it toward a light source, it will barely shine through to the other side of a very dirty air filter
