Very good
A filter that fits the air purifier once it is installed inside the device directly recognizes it and changes the filter usage period to read 100% without any effort And I noticed the air purification meter is very fast

Easy to install and works perfectly
Easy to install, just plug it in and it works straight away. The RFID is recognised correctly, and the display shows 0% as expected. Happy with it for now
