This Air Purifier from AmbientAir is a quiet and efficient device at £50 (selling only for £100+) It is quite large however aesthetically it looks good. It has a touch screen display on the top which is self explanatory. The instruction manual is easy to follow and informative. The display has a traffic light system to indicate the current air quality. The filter is effective against numerous different allergens and dust. It is a HEPA filter and I'm personally very impressed by the performance after using it for the last few weeks. Despite the size it's really quiet especially whilst using the night mode.
