Blueair - Replacement 7700 SmartFilter for Protect 7770i & 7710i Air Purifiers - Black

The Replacement 7700 SmartFilter calculates filter life based on an algorithm that considers fan speed, particle sensor data, and estimated filter loading. The filter life is displayed on the air purifier and/or the Blueair app.

The booklet design of the Replacement 7700 SmartFilter traps pollutants and maximizes the filter surface area. To minimize exposure to pollutants during replacement, users can fold the SmartFilter together like a book. This design feature helps contain any loose particles or pollutants within the filter, reducing the risk of exposure during the replacement process.

Genuine Blueair replacement filters are designed to maintain premium performance over time, ensuring the warranty remains intact. Unlike non-genuine alternatives, they feature an RFID chip that automatically resets the filter life status and provides accurate tracking to optimize filter usage and prevent unnecessary replacements.

The maximum filter life of the Replacement 7700 SmartFilter is up to one year, depending on room conditions. The air purifier or the app will alert you when it's time to replace the filter.

The DustMagnet technology in the Replacement 7700 SmartFilter utilizes a dual air intake, vortex airflow pattern, and electrostatic charge to capture dust before it settles. The electrostatic charge clusters airborne particles, causing them to stick to the pre-filters like a magnet, ensuring efficient dust removal.
