Levoit Air Purifiers
Some air purifiers lean on raw power, others on sleek design, but Levoit has made its mark by blending both at a price point that’s accessible. Founded in California in 2017, the brand is a relative newcomer compared to giants like Honeywell or Coway, yet it has quickly risen to become one of the best-selling air purifier names on Amazon U.S. Levoit’s appeal lies in modern styling, whisper-quiet operation, and a wide range of smart features usually reserved for pricier models.
With compact units for bedrooms, large-room flagships like the Core 600S, and a strong emphasis on app control and voice integration, Levoit has carved out a loyal following. Welcome to this expert review—let’s see how Levoit stacks up in real-world performance.
