Keep your home free from dust and dander with this Black & Decker air purifier. It works best in rooms up to 50 square meters, clearing the air of toxins so you can breathe easy. The Auto Mode is great for everyday use since it chooses the settings for you and immediately gets to work. Plus, with hot and cold functions, you’ll be able to keep your rooms free from germs and at the right temperature all year round – now that’s a breath of fresh air. There’s a HEPA 13 filter inside which removes 99.97% of allergens too, so anyone with asthma will feel much more comfortable. Want to know how long is left until the air is clean? The timer shows how long is left on the cycle so it's never on more than it needs to be.
