Filtrete 302-4 Air Filter, 20 in L, 20 in W, 5 MERV, 300 MPR, Synthetic Frame

You 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.

Measures 1 in thick, with filter media Fiberglass, frame material Synthetic, suitable for Air Conditioner Furnace and HVAC System.

Application

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
