Blueair 7770i Smart Filter Is just a NFC sticker. HEPA printer cartridge IMO.

Blueair 7770i “Smart Filter“ Is just a NFC sticker. HEPA “printer cartridge“ IMO. Blueair claims their SmartFilter “has a smart RFID chip that proactively monitors real-time usage and accurately judges when you need to replace it“ In reality, its just a sticker to monitor if you're using OEM filters. My 7770i was still moving lots of air when it was at 5% and now I can see why. I still like my 3 health protect Blueair filters but this seems dishonest to claim that there is any realtime monitoring on the actual filter itself.
