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.
