Levoit Core 300S-P review

The Core 300S-P is the value pick for a small bedroom or nursery. Levoit publishes a noise level of 22 to 50 dB, and the low end is the quietest floor among the app-connected purifiers on this list. The three-stage filter targets fine dust, smoke particles, pollen and pet dander, and the unit is rated for a 219 square foot room at 4.8 air changes per hour. Through the VeSync app you can set schedules and timers or pair it with Amazon Alexa or Google Assistant, so you can turn the fan down at bedtime without walking over to it. A sleep mode and a 1 to 24 hour timer are also on the unit. The limit is size: a CADR of 141 CFM is fine for a small room but not for a large open space. At $149.99 with a 2-year limited warranty and a 30-day money-back guarantee, it is the cheapest sensible start.

Who it is for

Small bedrooms and nurseries on a budget where app schedules and voice control are welcome.
