Application

For residential use only

• Outperforms fiberglass, washable and non-electrostatic three-month pleated 1 in home air filters for your furnace, air conditioner or HVAC system
• Designed with exclusive Filtrete™ brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner air flow through
• For optimum performance, change your home air filter every 12 months
• 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
• A dirty filter will slow down air flow and make the system work harder to keep you warm or cool
