Lennox OF25-120R Air Filter
Filters exist in many different types and sizes, depending on your desire for cleaner air and air handler requirements. The dimensions of the filter is not a choice that needs to be made due to the constraint of the availability of room of your system. HVAC specialists suggest that the air filter is exchanged for a new one every 90 days or so because the filter can get clogged and may result in poor air flow inside the house.
Some warnings the dust filter needs replacing ASAP
- When you face it toward a light, the light will almost not breach the other side of the filter
- The system air filter looks gray or brown and it would be best to replace it today
- It is greatly recommended to swap out your air filter every season of the year to help clean the indoor air
