The 3M Filtrete Premium Allergen & Ultrafine Particles Air Filter is a high-performance HVAC filter designed to help capture unwanted particles from household air, contributing to a cleaner, fresher home environment. This 4-pack of 14x30x1 filters features an MPR 2500 and MERV 14 rating with a 77% small particle capture rate, making it highly effective at trapping countless microparticles including dust, bacteria, viruses (up to 90% of airborne virus particles), pet dander, smoke, pollen, mold spores, dust mite debris, and household lint.

Designed with exclusive Filtrete 3-in-1 technology, the electrostatic pleated filter pulls in and traps unwanted particles while allowing cleaner air to flow through your furnace, air conditioner, or HVAC system. The white polypropylene construction provides both effective filtration and optimal airflow. Each filter lasts up to 3 months under normal use, and the Filtrete Smart App (iOS or Android) can be used to set 30-, 60-, or 90-day reminders for filter changes. Filtrete is North America's most trusted brand of HVAC filters and the number one recommended HVAC air filter brand, delivering breakthrough technology to filter out both large and invisible particles for a cleaner, healthier home environment.
