Philips AC0820/30 Series 800 Compact Air Purifier

The Philips Series 800 AC0820/30 Air Purifier keeps a keen eye on your air quality. It has a sensor to monitor your air and adjust its speed accordingly. And you get a 4-step coloured display to visualise your air quality - blue being clean, red poor.The Series 800 is compact enough to fit pretty much anywhere.

It even features a night time mode which slows the fan speed and turns off display lights. Almost silent then, it's great for a bedroom or a baby's room.
