Filtrete MPR 1900 Premium Allergen, Bacteria and Virus Smart Air Filter, made by 3M, helps attract and capture unwanted microscopic and large particles to contribute to a cleaner, fresher home environment, while Bluetooth technology helps track filter life. CERTIFIED asthma and allergy-friendly (1), with a MERV 13 rating and high MPR rating of 1900, your AC filter will capture many microparticles – such as pet dander, smoke, bacteria and viruses – letting cleaner air flow through. Your filter will also capture large particles, including lint, pollen and household dust. With a Bluetooth-enabled sensor to track filter life based on data from your home's HVAC system, you can track the life of your Filtrete Filter based on air flow and usage – not just time. The easy setup involves downloading the Filtrete Smart App and pairing the smart air filter to your smartphone. When it's time to replace your furnace filter, you will be notified, so you never have to worry about changing your air filter too early or too late. The Filtrete Smart App is available on iOS and Android. (1) As outlined in report ASCR: 1246-01. (2) Based on the 2022 Ipsos US Brand Health Study of Residential HVAC Air Filters.
