We were able to test this air purifier for 2 weeks. The device is easy to install and feels solid. The design is stylish, so it stands out in a positive way. The accompanying app is easy to download and install. You can add the device to the Philips app via WiFi. There you can see the current air quality and you can activate the child lock (very handy), for example.
It was mainly on the automatic setting. In that setting it can suddenly start blowing very hard. I find that striking and that sound is also noticeable. On the silent setting it is really quiet and constant. So you can also leave it on that setting.
It was in our kitchen. You do indeed notice that you have a blocked nose less quickly, the air is also fresher. With the timer function you can also easily activate it whenever you want. For example, half an hour before you get up.
