The Slevoo Air Purifier is a great choice for anyone who wants to keep allergens out of the air in their bedroom. It’s the quietest purifier we tested, and it has a lock feature that keeps curious little hands from turning it on or off.
The Slevoo’s five-stage filtration system includes a pre-filter, H13 HEPA filter, and three types of activated carbon, resulting in 99.97 percent removal of 0.3-micron airborne particles, including pollen, pet dander, and dust. The purifier was so effective at removing smoke that our tester who can usually smell cigarettes when someone smokes within 100 feet of her said she couldn’t smell anything.
The Slevoo has a few additional features that make it stand out from the crowd: a child lock button to disable the on/off switch, an indicator for when it’s time to change out the filter, and a fragrance sponge available as an add-on for those who want to get rid of odor without using chemicals.
