An inexpensive little device has just been launched to help keep your home dust- and allergen-free, without the need for harsh chemicals.

Cleanaer, which has been tested and endorsed by reliable bodies like the World Health Organization and Imperial College, reduces smoke and dust, allergens, and other “undesirable airborne particles”.
