AL42-4

For allergen/dust defense and residential use

Outperforms fiberglass, washable and non-electrostatic 3 months pleated 1 in home air filters for your furnace, air conditioner or HVAC system

Designed with exclusive Filtrete™ brand three-in-one technology from 3M to trap unwanted air particles while letting cleaner air flow through

Attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog

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

For optimal performance of your heating and cooling system or HVAC system, change your home air filter at least every 90 days for 1 in filters

A dirty filter will slow down air flow and make the system work harder to keep you warm or cool wasting energy, sign-up for a filter change reminder program that works for you

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
