Overall Rating Snapshot

Cleaner Air
We’ve been using the Philips Purifier/Humidifier now for a few weeks now and have been really impressed. The air feels noticeably fresher, especially in the mornings, and it has helped a lot with dust and stuffiness in the bedrooms. We also like the humidifier function, which has made the air feel much more comfortable during colder nights when the heater is running. The app setup was straightforward and it’s handy being able to check air quality levels in real time. The unit itself looks modern and blends in nicely with the home rather than looking bulky or clinical. What surprised us most was how quiet it is on sleep mode — we can leave it running overnight without it being disruptive. Water tank is easy enough to refill and maintenance so far has been simple.
