Levoit Core 300S vs Dreo Air Purifier 338S

The Dreo Air Purifier 338S and Levoit Core 300S are closely matched compact smart air purifiers. The Levoit has a somewhat higher clean air delivery rate and can effectively handle a slightly larger room, while the Dreo runs a little quieter. Both offer companion apps, automatic air quality monitoring, timers, and displays that can be turned off for bedroom use. The Dreo distinguishes itself with adjustable ambient lighting and an aroma pad compartment, while the Levoit offers a broader selection of specialty replacement filters designed for needs like smoke, toxins, and pet allergens.
