After using the Philips PureProtect Mini 900 series air purifier for a few weeks, I am satisfied with its performance. It is quiet and responds quickly to changes in air quality, which is nice for smaller spaces like the bedroom. The automatic mode adapts effortlessly, making it very easy to use.
The filter system is efficient in removing dust and allergens. My family has noticed a noticeable improvement in air quality, which is nice for our allergies.
There are a few drawbacks. The design is functional, but not very attractive; it does stand out visually in the room. In addition, this model is less suitable for larger living rooms. For larger spaces, a more powerful and somewhat nicer model would be a better choice.
Overall, the Philips PureProtect Mini 900 series does what it is supposed to do: it improves air quality in small spaces, and it is quiet and easy to use.
