Dyson Purifier Cool TP4B
Score: 75/100Rankings
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 Dyson Purifier Cool TP4B is a 2-in-1 appliance that combines air purification with cooling fan functionality. It utilizes a fully-sealed HEPA H13 filter and activated carbon layer to capture 99.97% of particles as small as 0.3 microns while removing gases, odors, and harmful toxins like formaldehyde. The device automatically senses air quality changes, displays real-time pollution data on an LCD screen, and offers up to 350° oscillation with a backwards airflow mode for purification without cooling.

Experts praise its superior performance, highlighting the advanced 360-degree intake design that ensures even airflow and efficient cleaning while automatically adjusting to detected pollutants. Reviewers specifically note that the HEPASilent™ technology operates faster and quieter than traditional HEPA systems.
Everyday users consistently praise the purifier for its rapid pollutant reduction capabilities, seamless app integration for monitoring and scheduling, and exceptionally quiet night mode operation. Recurring complaints focus on the single-filter replacement requirement and the unit's bulkier size.
Professional reviewers and editors highlight that the TP4B delivers premium air purification performance comparable to Dyson's higher-end models, thanks to its fully-sealed HEPA H13 filtration system which captured over 95% of monitored particles in testing. Experts agree that the device offers excellent value for money, as it maintains identical core cooling and purification capabilities while costing approximately $100 less than the TP07 sister model. The consensus is that sacrificing smart home integration is an acceptable trade-off for most buyers seeking reliable air quality management without unnecessary connectivity features.
