Dyson Purifier Cool TP4B
Score: 75/100Rankings
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.
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.

Professional reviewers praise the PuroAir 240 for its highly effective H14 HEPA filtration system, whisper-quiet operation, and strong performance-to-price ratio. However, experts criticize the manufacturer's exaggerated marketing claims regarding room coverage and note slower cleaning times with standard filters.
Everyday users consistently praise the intuitive auto mode, rapid sensor response, and quiet performance in larger rooms. Common themes highlight effective relief from allergies and pet dander alongside a straightforward filter replacement process.
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.
