Puremate compact HEPA air purifier model no. PM501. Filtration has 3 stages - Pre Filter, Activated Carbon Filter and True HEPA filter so effective for dust, smoke, pet odours, pollen and pet dander to name a few. It has a sleep mode so that unit runs a low speed. Suitable for a room 10-15m2. 11" high by 7" diameter. Had very little use - the filter still looks like new.
