About this item

  • TRUE HEPA FILTRATION: Airthereal’s 3 Filtration Stage True HEPA Filter will help you breathe easier by removing particles as small as 0.3 microns. A human hair has a diameter of around 50 microns, so our filter can remove particles that are 500 times smaller than a human hair.
  • SILENT OPERATION: Tired of lying in bed at night listening to the hum of your air purifier? No more! The max operating noise in sleep mode is a mere 22 decibels, making it even quieter than a whisper or a small public library.
  • AROUND THE HOUSE: The ADH50B is so lightweight that you can simply unplug and move to wherever you spend the most time. There’s no need to pay extra for a bigger machine to purify your entire home when you can have super-clean air wherever you set up the purifier. Clean the air you breathe most by moving the air purifier to wherever you are located at the moment.
  • FILTER CHANGE REMINDER: All air purifier filters will decrease after a few months of usage. Airthereal air purifiers come with a built-in filter change reminder so that you can continue to keep the air in your home in the cleanest condition. For best results, use an authentic Airthereal ADH50B replacement filter available on.
  • CARB & ETL CERTIFIED: ADH50B meets the strict safety requirements of CARB and ETL certification.
  • Note: This unit is powered by a DC adapter (120V 60Hz to 12V). Power supply over 120V can cause damage to the unit. Ensure to connect with the appropriate power supply socket. Make sure to remove the plastic wrap from the filter before turning on the air purifier.

1.0 out of 5 stars Fatally flawed
Reviewed in the United States on December 11, 2019
UPDATE: I want to love this, as the size is great and DC compatibility is rare. But it has a fatal flaw: the power port (where the power cord plugs in) is very small, flimsy, and cheaply made. You can see other reviews here that say the same thing. Mine has felt loose and wiggly for a month or two now (meaning the power would jolt off if I so much as gently bumped the thing), and today the port just completely fell apart ~ two pieces broke off, and there is no longer any way to get power! We are in the middle of wildfire season, so I have been relying on this for my health. Quite a terrible time to break!

. . .
Original Review:
This product has been working fairly well for me, so I can’t really complain – but if I had to be nit-picky I could point out a few things:

1) one of the lights on the control panel went out – the one where I press to choose the speed (see picture). So I have to know where to press from memory.

2) The #1 (low) setting is quite significantly lower than settings 2 & 3. I like how quiet it gets, but I’m not sure the setting is very effective. Still, I set it there at night for quiet.

3) I’m not a fan of lights on gadgets, so I don’t like the LED screen. Fortunately, a wide-mouth jar lid insert fits perfectly over it (see 2nd pic).

In all, it strikes me as a sufficient little machine. I use it for my long+tall Sprinter van, which is about the size of a small room. I did have to replace the filter after only 5 months, but given that it’s a vehicle, a bit more dust and pollution is to be expected.
