According to our air purifier expert
The built-in UV-C lamp kills harmful bacteria, viruses, and fungi.
As soon as the air purifier measures a change in the air quality, it adjusts its operation with the automatic mode.
With the app, you can also control the air purifier remotely or when you're not home.
This air purifier is only suitable for smaller rooms of up to 28m2.
You need to regularly replace the air purifier filters for the best result.
Easy to use, exactly what I wanted.

Unfortunately, I'm disappointed with the air purifier. I bought it to eliminate unpleasant odors in my house, but I hardly notice any difference when it's running. I don't have allergies, so I have no idea if it has any positive effects on them.

It was easy: take it out of the box, remove the filter from the plastic, turn it on, and it starts filtering the air immediately.
Connecting the app was also easy; operating it with the app is simple. You could potentially set a schedule for switching it on or off. I’ve been using it in the bedroom for a few days now and really feel like I sleep better, have almost no dry mouth anymore, and cough less.
