After testing the Philips air purifier for a few weeks, I am very excited about what it has to offer. The installation was surprisingly easy; I didn’t need a manual and connecting to WiFi was done within a few minutes. The air purifier is now in our bedroom and I immediately noticed an improvement in the air quality. The device works perfectly without the app, thanks to a simple display that doesn’t emit bright lights. However, in the app you can set various functions, such as the ‘fresh bedtime’ mode, which is ideal for a good night’s sleep, and the ‘fresh wakeup’ mode, which ensures a fresh start in the morning. I found the ‘allergy sleep mode’ a bit noisy, because the device would turn up the volume when allergens were detected. That’s why I often opted for the regular sleep mode, which produces a constant, soft sound while still maintaining good air quality. The auto+ mode is ideal for daytime, because the device automatically turns up the volume when the air quality is poor, for example when I’m cleaning. This device really gives me more peace of mind about the air quality in my home and I would definitely recommend it.
