Works well at first. The filter eventually holds a smell. Please keep in mind I've regularly checked and vacuumed the filter to help extend it's life and keep a clean home.
Although the unit reads the filter doesn't need replacing, it is clear by looking and a whiff of the filter that it does. Also, it shakes and vibrates a lot on settings 2 and 3. Plastic rattling, loud whirling, can't sleep at all vibration and noise.
Lastly, the fan blows okay however the angle of the vents is a bit strange and blows down to the right of the face of the unit... I have had this unit for roughly 8 months, and am writing this after walking into a Brookstone and looking at some of their filterless air purifiers. 50 bucks more and you just clean the filter, and blows twice as hard with no loud noises. Time to save up again, and I'll put this one in the spare bedroom I guess... Hoover, back to the drawing board? The 10600 is okay at best. Not worth $200.00 though. Sorry guys!
