The Filter Frame in your Filtrete 3M 16x25x1 MPR600 is essential for trapping dust, pollen, and other airborne particles. Over time, the filter media can become clogged, reducing airflow and filtration efficiency. Replacing the Filter Frame regularly ensures your air purifier continues to function optimally.
Function: The Filter Frame traps airborne pollutants, preventing them from recirculating in your environment.
Signs it needs replacing: Reduced airflow, increased noise levels, or visible accumulation of dust on the filter media.
OEM vs aftermarket: OEM parts are manufactured by Filtrete 3M and offer guaranteed compatibility. Aftermarket options may be more affordable but require careful verification for fit and quality.

Replacement schedule: every 2 months
Compatibility warning: always verify part number matches your exact model before ordering
