Sharper Image Ionic Breeze Quadra Silent Air Purifier

Circulates air in total silence, propelled by patented, solid-state electronics. It works like a charm!! Proven air-cleaning technology traps airborne irritants and contaminants on permanent, electrostatically charged, stainless steel collection blades. No filters to replace, just wipe clean with a damp cloth. This is the best feature, other than it being totally silent! It cleans the air 24/7 and reduces odours, too!
