The Blue Pure 511i Max is Blueair's compact smart air purifier for rooms up to about 526 sq ft. It pairs a HEPA and carbon filter with Wi-Fi and Alexa voice control, a display and a timer, and tops out at 48 dB. It is smaller and cheaper-feeling than Blueair's larger Pure 211+ and 311 models, but it adds app control those lack. Owners like the simple fabric-wrapped design and quiet low setting; some find the fan noisy at full speed and the filter replacements a recurring cost.
