Comparison: Dyson HP01 vs HP04 vs HP07 – What are the Differences?
Coverage Area & Efficiency
While the HP01 oscillates up to 70 degrees, the HP04 and HP07 allow for even better coverage of the whole room thanks to an adjustable oscillation angle of up to 350 degrees.
With a purification coverage of 73 m³ (2610 ft³), the HP01 is designed for slightly smaller areas than its two successors with a purification coverage of 81 m³ (2860 ft³).
As for the heating feature, Dyson recommends a room size of about 35 m³ (1236 ft³) for the HP04 and HP07. Unfortunately, there was no information available for the HP01.

Clean Air Delivery Rate / Airflow
All three devices utilize a HEPA filter to capture 99.97% of particles as small as 0.3 microns and activated carbon to remove odors and gases including VOCs.
Certified asthma and allergy friendly by the Asthma and Allergy Foundation of America, the HP01 then projects 200 liters (53 gallons) of purified air per second throughout the room. Both the HP04 and HP07 have an even stronger airflow of 290 liters (77 gallons) per second.
The HP07 is the first of the three devices to be fully sealed to HEPA H13 standard, allowing it to remove 99.95% of particles as small as 0.1 microns and guaranteeing that the captured pollutants stay inside the machine.

Working Noise
Even on the maximum speed setting, the HP04 and HP07 generate not more than 62 decibels (dB) of noise. Using the integrated automatic mode will make both air purifiers run only as fast and therefore as loud as needed.
Once the pollution levels decrease, the speed levels will decrease with them. Before you go to sleep, you can also limit both devices to Level 1 to 4 out of 10 using night-time mode. With the HP01, you have to make all changes manually.
