I just received my air purifier Philipps 4072. I will not conceal that initially I was a bit skeptical and I asked myself at length about the usefulness of this device. My first impressions were good when unpacking. The device is quite large, and seems robust. The design is really beautiful. After ignition, the LEDs light up. Violet initially sign of a pretty good, it quickly becomes blue (looks very good). You really feel the difference when passing next to the device. The air seems fresher. We believe the installation. I positioned the camera in my living room with open kitchen. And surprise, beyond the start of cooking, the camera turns red (bad air). The fan turns on automatically, and also filter odors. So I'm really happy with this unit. It deserves 4 or 5 stars. However, 499 for this device seems excessive. So I removed one star.
