- How often do I need to replace the filter?
- Shark rates the NeverChange HEPA filter for up to five years of use. You rinse the washable parts regularly, and the HEPA core is replaced far less often than typical filters.
- What size room does it handle?
- It is rated for rooms up to 250 sq ft, so a bedroom, office or small living area. For larger or open-plan spaces, a bigger unit with higher clean air delivery is a better fit.
- Is it quiet enough to sleep next to?
- On its lower speeds it is quiet enough for most bedrooms. The higher speeds are clearly audible, so run it low overnight.
- Does it remove odors as well as dust?
- It uses a HEPA filter for particles like dust, pollen and pet dander. Odor and gas removal is limited compared with purifiers that add a dedicated carbon stage.
- How big and heavy is it?
- It is about 11.6 inches tall, 9.2 inches wide and deep, and weighs 4.4 lb. That makes it easy to lift onto a desk or nightstand.
- Does it have an auto mode or air-quality sensor?
- No. You choose among five fan speeds manually; there is no sensor-driven auto mode on this model.
