2026 verdict
It comes down to room size versus value.
The Blueair Blue Pure 511i Max wins this air purifier head-to-head on price, a washable pre-filter and PM1, PM2.5 and PM10 sensing, while the Levoit Core 600S-P reads PM2.5 only and replaces its pre-filter with the cartridge. The Levoit Core 600S-P is the much larger machine, rated at 391 CFM for up to 606 ft² against 153 CFM for 237 ft², and it adds a two-year warranty, a remote control, an LED screen and Home Assistant support. Choose the Blueair Blue Pure 511i Max for a single small room, and the Levoit Core 600S-P when the space is big or open.
