Bacteria, germs, mold spores, pollen, pet dander, smoke, dust and odors can make breathing harder, especially for asthma and allergy sufferers. Sharp Plasmacluster Air Purifiers remove these irritants with an ultra quiet fan that draws air through a three-stage filter system. Plus their revolutionary Plasmacluster Ion Technology actively treats the air to make it healthier and cleaner smelling. The model FP-P60CX is powerful enough for a living room or family room, while the FP-P40CX is ideal for a study or bedroom. Both are a smart way to choose cleaner, healthier, more breathable air. The FP-P40CX combines passive air filtration with active air treatment to help clear the air of pollen and airborne irritants. As a result, Sharp's air purifiers go beyond conventional systems - and are ideal for those who are sensitive to dust or allergens. The unit's elegant design will also look great in any room.
