Replacing Your Filter
For maximum effectiveness, we recommend you change your filter at least once every three months. You may want to change the filter more frequently if:
- You are remodeling or there is any other kind of construction work in progress
- There is any furniture or drywall sanding in process
- You own pets
- Anyone in the home smokes
- There is a fan running continuously
