A fresher home starts with Shark's sleek air purifier. The clever DebrisDefense™ pre-filter prevents buildup of dust, hair and lint then removes for easy cleaning—just wipe, vacuum or rinse. Consisting of a washable filter, an Activated Carbon layer, and an advanced multi-layer filtration system that exceeds HEPA standards, the NeverChange™ filter delivers up to six years of powerful purification with zero filter changes. The system traps 99.98% of allergens, dust, pet dander, pollen, smoke and other particles. Choose fan speed, or let the auto mode adjust the fan to suit your space with advanced sensors that scan the air 3,600 times per hour for odors, VOCs and particles to react instantly. Powered by the BreatheClear operating system, an intuitive screen displays real-time air quality reports, while smart motion and light detection automatically boost purification when physical activity is sensed and dim the display in low light.
