The Filtrete Dust & Pollen Filter should be replaced at least every 3 months.
In a typical home, an air filter will become completely clogged with tiny particles of dust, pollen, mold, etc. after around 3 months of use. Certain conditions can add more particles to the air, and reduce the life of the filter to less than 3 months.
Change your filter more often if you have:
- Pets
- Dirty ductwork
- Recent construction work or a sanding project
- Smoke from cigarettes, a fireplace, a wood-burning stove, or candles
Why should you change your filter on time?
As the filter reaches the end of its life, the clogging makes the fan work harder and harder to push the air through the filter. This restriction can reduce the airflow through the house, and may affect the performance of the heating & cooling system.
