So out of the box it looks great, it could be part of wireless speaker system. The unit feels solid and well made, with 2 handy carry handles.
You can just simply turn the unit on & adjust the speed in manual mode, but it's definitely worth reading the manual! For example, do not expect the filter to work effectively if all the doors and windows are open. It is very quiet on low, about as loud as a fridge when running on full (which doubt will be very often). To get full functionality you will need to download the app. I had to hunt around about for the app on Apple store (not sure about Google store), it's called 'AEG Wellbeing'. Maybe could use a QR code on box?
Once downloaded, connecting everything up via Wifi is easy (you will need to create a basic account).
The App is pretty intuitive. You get a 7 day x 24 hour timer so can clean the air while asleep or at work if required. You can also see full hour by hour display of air quality and humidity in home. The filter can be vacuumed but will eventually need replacing. I'm unsure of life, but guess it really depends on how polluted you house is. The filter life is displayed on app, it's been running for 2 weeks and still on 100% so hoping its ages until I have to get a new filter. Auto mode normally uses PM2.5s (from Diesel cars, wood smoke, etc.) to drive fan speed. The sensors are very sensitive, normally mine runs on green (good air) but if you start cooking it quickly goes amber and ramps up the fan speed to increase air scrubbing.
It also appears to be very handy to remove odours (and VOCs?) from decorating or cleaning. The app also gives you hourly totals for reduction in all the various items the unit can cope with (e.g. PM2.5, PM10 and volatile organic compounds).
Overall, it seems to be doing a solid job of cleaning air in house. It's not quite the season yet, but wife gets bad hay fever so hoping this can really reduce pollen inside.
