Improve the air quality in your home with the powerful Shark HE601, an air purifier that actively monitors rooms up to 1,200 square feet.

This air purifier uses six fans to circulate airflow in a room, delivering purified air faster and quieter than purifiers with fewer fans. The control panel displays air quality info and has options to customize fan speed, power mode, and brightness. There's also a remote control so that you can adjust the purifier without getting up from the couch.

The best air purifiers get rid of not only allergens, but also unpleasant odors, and the Shark unit does the latter extremely well. It's equipped with an Anti-Allergen HEPA Multi-Filter, which captures dust, dander, allergens, and smoke, as well as an advanced odor guard that works to eliminate household odors from cooking and cleaning products.
