303-4

For residential applications

Outperforms fiberglass

Designed with exclusive filtrate brand 3-in-1 technology from 3 m to trap unwanted air particles while letting cleaner airflow through

Attracts and captures large particles such as lint, household dust and dust mite debris

The higher the MPR, the more micro particles such as pollen, pet dander and smoke - your filter will capture from the air passing through it

Change filter at least every 90 days for optimal performance of your heating and cooling system or HVAC system

A dirty filter will slow down airflow and make the system work harder to keep you warm or cool - wasting energy

Create a change countdown in the Filtrete™ smart app

Simply use the app to scan the barcode on your filter's packaging, then choose 30, 60 or 90 days for your replacement countdown, when the lifespan is up, you'll get a notification to change your filter
