Large H13 HEPA Filter
The cylindrical filter has a larger surface area than flat filters and an upgraded H13 HEPA filter which removes 99.97% of 0.1-micron particles of allergens, dust, dander, and pollen.
Quiet Sleep Mode
Enjoy a restful night of sleep with a constant supply of fresh air. Activate the sleep mode to run at the quietest fan level and dim all lights.
Adjustable Timer
1-2-4-8 hour timer enables better scheduling for your life. The timer saves you time and money, as well as extends the lifespan of the machine.
Powerful Motor
We've adopted DC motors in the Day Dawning ADH70, which allows it to achieve a higher purification capacity than other motors.
Portable Design
With the vegan-leather handle, Type-C USB power cable, and compact size you can carry it anywhere in the house to filter the air.
