Blueair Blue Pure 511i Max vs Dyson HushJet

The Blueair Blue Pure 511i Max and the Dyson Hushjet are very similarly performing air purifiers overall. The Blueair's main appeal is that it delivers a very similar feature set and overall experience at a more accessible price, while the Dyson's quieter operation gives it a narrow edge for those who prioritize that above all else. Both are compact, app-enabled models and the smallest in their respective manufacturers' lineups, with a cylindrical 360-degree filter design suited to bedrooms, home offices, and other smaller spaces. The Blueair is the more compact of the two, taking up less space on nearby furniture. Both are whisper-quiet at lower fan settings, though the Dyson holds a slight edge in noise performance. The Blueair, meanwhile, offers slightly higher airflow at maximum fan speed. For most people, however, the overall differences are minor.
