## Description

Genuine Blueair replacement filter compatible with Protect 7470i and 7410i air purifier models. SmartFilters are designed to deliver superior performance with data-based filter lifetime tracking, a smart RFID chip, and longer filter life (maximum of 1 year). The combination Protect 7400 SmartFilter features a particle filter layer to remove airborne particles like pollen, dust, mold spores, pet dander, viruses and bacteria, fine smoke particles and more.*The activated coconut carbon layer absorbs gases, Volatile Organic Compounds (VOC), chemicals, odors, exhaust and more. Accurate filter life tracking helps you get the most out of your Protect 7400 SmartFilter and eliminates unnecessary replacement with an algorithm to calculate filter life based on fan speed, particle sensor data, and estimated filter loading. View data anytime via the app. Once replaced, the air purifier will recognize the new filter’s RFID chip and automatically reset your filter life status. Please check your local recycling facilities for availability. Authentic Blueair replacement filters are specifically designed for optimal performance over time. Your SmartFilter will last a maximum of one year depending on room conditions. To ensure performance, replace your filter when alerted by the air purifier and/or app that replacement is needed.NO COMPARISON: Blueair models with HEPASilent's mechanical and electrostatic filtration produced higher CADR, lower noise, and had lower energy consumption vs. the same models with only mechanical filtration (H13 filter). 24/7 PROTECTION*: 24/7 protection refers to the key function of GermShield technology, that is activated when the unit is in standby mode. Tested on Staphylococcus albus and MS2 bacteriophage (deactivation) and Ecoli (growth prevention). Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19.

Review: These filters aren't cheap to buy but ours lasted almost a year with constant use. The filter is real easy to replace. We have 3 air purifiers throughout our house and the Blue Air 7400 is by far the best.
Review: A necessary item for my air purifier. Fits perfectly and eliminates the need for me to contact the parent company.

Works as advertised. OEM guaranteed to work. This resolved my issue where the fan would be on auto and alternate between full-blast and minimal strength.
