Plasmacluster tested: Sharp FPA80UW purifies, 2,198 sq ft, HEPA filtration natural We were impressed by how the Sharp FPA80UW covers vast spaces like ours, purifying 2,198 sq ft with its powerful Plasmacluster Ion and Triple Filtration system. The True HEPA filter proved effective against dust, smoke, and pollen, making the air feel cleaner almost immediately. We appreciate that Sharp combines advanced technology with a natural approach, as the Plasmacluster Ion function mimics waterfalls to freshen the air subtly. The unit’s sleek design fits seamlessly into our living room, and the quiet operation means we hardly notice it running. While it’s on the pricier side, the FPA80UW delivers reliable results for large rooms. For us, it’s a worthwhile investment in breathable, cleaner air.
