Blueair Blue Pure 311i Max, decisively, at 7.8 W against 66 W. Both are Energy Star certified, but the Blueair is the least power-hungry purifier in this comparison for its coverage, which adds up on a device designed to run continuously.

Levoit Core 600S-P uses a sealed 3-stage H13 True HEPA cartridge rated at about 8 months, whose pre-filter layer is vacuumed rather than washed and replaced together with the rest.

Levoit Core 600S-P, which adds Home Assistant support through VeSync on top of Alexa and Google Home, plus a physical remote and child lock. Blueair Blue Pure 311i Max stops at Alexa and Google Home with no remote, though it does show PM1, PM2.5 and PM10 on the unit itself.

Anyone covering an open floor plan, a high-ceilinged room or several connected spaces with one machine, and anyone who wants a 2 year warranty and Home Assistant control. For a bedroom, office or ordinary living room, Blueair Blue Pure 311i Max is the more efficient and better-informed choice.
