Blueair Pure 211i Max
Score: 91/100Rankings
The Blueair Blue Pure 211i Max is a high-performance air purifier for large rooms, utilizing HEPASilent™ technology to deliver exceptional CADR ratings and rapid pollutant removal. Its smart app integration and real-time air quality sensors make it a top choice for automated air management, though its bulkier size and single-filter design are notable trade-offs. It is ideal for allergy sufferers and pet owners in large living areas who prioritize cleaning power and efficiency.
The PuroAir 240 is a compact, energy-efficient air purifier designed for rooms up to 1,000 square feet, utilizing a three-layer H14 HEPA filtration system. It features whisper-quiet operation and an auto-adjusting air quality sensor, positioning itself as a high-value option for allergy sufferers. However, the advertised room coverage is optimistic, and it lacks smart app connectivity.
