Description
xYou run a tight ship at home, from floor to ceiling - and everywhere in between. Unfortunately, ordinary home non-electrostatic air filters aren't super effective at capturing unwanted particles. Good news - the unique design of the electrostatically charged Filtrete™ pollen air filter attracts - and traps - more particles from your air through your heating and cooling system, making quality control a breeze. With each cycle through the filter, your indoor air becomes a little bit cleaner.
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
