Considering how well Dyson does with household devices, it isn’t surprising to see the Dyson TP04 Pure Cool Tower make a stand as a top-rated air purifier. But does it do well as the best large room air purifier? Its performance certainly tries, along with smart features and an Auto Mode for setting and forgetting.

Why We Like It – Dyson TP04 Pure Cool Tower

The Dyson TP04 Pure Cool Tower not only makes big upgrades from previous generations, but also steps forward into the modern age with smart features to accompany the fantastic performance.

  • Incredibly efficient & powerful
  • Integrated smart features
  • Auto Mode is for setting & forgetting
  • High price tag

Power & Speed

There’s ten different speeds to choose from, whereas most have three or maybe four. Setting it to the highest will net you around 900+ CFM. Even with such strong airflow air speeds, it’s surprisingly efficient with energy consumption, only ever using 56 watts at its highest speed.


But what kind of coverage does that entail? Dyson tested the Dyson Pure Cool TP04 Purifying Fan with 290 feet squared in mind, but it still does exceptionally well in a 400-square foot room. Alternatively, you can use Fan Mode to cool yourself or use Airflow Mode to improve indoor air quality without blowing cool air on yourself. However, the Alen Breathesmart Classic Large Room Air Purifier covers 1100 sq. ft.


Unlike the Coway Airmega 300, the Dyson Pure Cool Purifying Tower Fan TP04 doesn’t have a pre-filter; dust pollen and other particles go straight to its HEPA filter. At that stage, 99.97% of particles as small as 0.3 microns are trapped. Afterward, the activated carbon filter kicks in and handles odors and harmful gases (like nitrogen dioxide).

This is Dyson we’re talking about, so of course, durability is quite good. It’s nearly 11 lbs and measures 8.77 x 8.77 x 41.49 inches. There’s a large base for better stability, but it’s rather tall, like the Envion Ionic Pro, so take care not to accidentally topple it over. For a sturdier option, check out our review of the Coway Airmega 400.


There’s no debating the efficiency and power of the Dyson Purifying Fan TP04. Dyson air purifiers have come a long way, and the TP04 Pure Cool Purifier Fan is the result of that. However, it’s too expensive, plain and simple—especially compared to a Coway Airmega 400. Sure, the Dyson Link app is nice for scheduling and keeping tabs, as are real-time air quality reports, so it comes down to preference. And don’t forget: you have to purchase replacement filters, too. If you want an affordable air purifier then you ought to consider our Elgato Eve Air Quality Room Sensor review.

Dyson TP04 Pure Cool Tower Wrap Up

The Dyson TP04 Pure Cool Tower is packed with features, a great design, and incredible performance. Its filtration system traps 99.97% of particles as small as 0.3 microns, and it feels right at home in 400-square-foot rooms. However, that doesn’t change the fact that it’s overpriced.
