Design and features


The only setup required for the AIRTHEREAL Day Dawning ADH70 HEPA air purifier is to install the filter and plug it in.

After removing the packaging, you need to open the bottom cover by rotating it counterclockwise. Then you slide the filter into place and put the cover back on by turning it clockwise.

You should find a solid, flat surface for the AIRTHEREAL Day Dawning ADH70 HEPA air purifier to work optimally. Also, place it at least 15 inches away from TVs, radios, or other electronic devices.

You connect the power cord using the Type-C USB cable that comes with it. When it’s plugged into a proper power source, it will beep.


To turn on the AIRTHEREAL Day Dawning ADH70 HEPA air purifier, press the power button. It will light up blue and default to medium speed.

If you click and hold the “lock button” for 3 seconds, it will turn on a child lock. Hold for 3 more seconds to turn it off.

The light (sunshine) button lets you turn on or off the glowing blue light.

The fan speed (wind gust) button lets you choose from low (1), medium (2) or high (3) air circulation speeds.

The button at the bottom glows red to indicate when it’s time to replace the filter (press and hold for 5 seconds to turn it off).

You can set a timer (stopwatch button) for 1, 2, 4, or 8 hours or leave it on to run continuously.

The sleep mode (moon) will put it to the lowest fan speed and turn off the display but keep the bottom light on. Use the light button to turn all lights off.

The AIRTHEREAL Day Dawning ADH70 HEPA air purifier is very easy to use. It’s quiet. And it has a nice soft, blue glow and looks attractive.

My son doesn’t mind sleeping with the blue light on all the way; I would turn it off if it was in my bedroom at night. It’s nice to have the option to adjust it to your liking.

The AIRTHEREAL Day Dawning ADH70 HEPA air purifier is very compact, light (less than 2 pounds!), and easy to move. It even comes with a carry handle.

This air purifier is recommended for a coverage area of up to 300 square feet. We use it in a bedroom, and it’s helped keep the room fresh and keep out allergens during this high-pollen season.

What I like

  • Easy to use
  • Works well
  • Looks nice

What I’d change

  • Nothing

  2. Hi. I am just curious if you were able to verify the 41 CFM stated by the manufacturer. (I don’t know what sort of equipment you have). I just bought this unit and I am surprised at how quiet it is. I doubt it reaches 55dB at high speed, so I’m wondering if the fan is strong enough to reflect actually having a CADR of 41 CFM.
