Levoit Core 300S-P review

The Core 300S-P is the cheapest way to get a real HEPA-style purifier with an app. Levoit sells it for $149.99 with free shipping, a 2-year limited warranty and a 30-day money back guarantee. Its published CADR is 141 CFM (240 m³/h), well below the 233 to 253 CFM of the Coway Airmega Mighty and Winix 5520, so it suits a bedroom or a small office rather than a living room. Levoit quotes a 1,051 sq ft figure, but that is for one air change per hour; at the 4.8 changes allergy guidance assumes, the coverage is far smaller. Where it does well is noise: the range is 22 to 50 dB, the lowest floor on this list. The VeSync app handles schedules, timers and Alexa or Google Assistant control, and there is a 1 to 24 hour timer, sleep mode and a check-filter light. Levoit's page lists a Core 300-P Replacement Filter 2-Pack for $54.99.
