Honeywell HFD-120
Score: 62/100
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 Honeywell HFD-120-Q is a budget-friendly tower air purifier designed for small rooms up to 170 square feet, featuring washable IFD filters and oscillation. Its main trade-off is the lack of advanced features like timers and smart connectivity, along with lower particle capture efficiency compared to HEPA models. It is best suited for allergy sufferers managing light dander and dust who prioritize low maintenance costs.
