Captures 99.95% of particles Enjoy cleaner, purer air with the Russell Hobbs Clean Air Pro RHAP2001B Air Purifier. Its 3-layer filtration system captures 99.95% of particles. That includes smoke, pollen, and dust particles as well as pet dander, so it's perfect if you or your family have allergies or asthma. Designed for small and medium-sized rooms It can purify the air in rooms up to 14m², so it's ideal for bedrooms, living rooms or home offices. The sleek design and colour-changing LED light will make it an ideal addition to any room you decide to place it in. Easy-to-use controls The touch controls and 3 speed options make it easy to adjust the settings to suit each room. You can also set a timer for up to 8 hours, so that the Clean Air Pro runs for a set amount of time. If you're a light sleeper, you'll appreciate the Night Mode function. This dims the LED display and slows down the fan speed, so you can enjoy a good night's sleep while the air is being purified.
