Review: Bought it because it runs on 12 volt - Bought this because the specifications noted it runs on a 120 to 12v adapter. While it doesn't come with a 12v direct plug, I was able to cut/splice in a cigarette lighter plug, and it works great running on the 12 volt in my trailer for those rare but inevitable california smokey days. I was hoping to use a standard 5.5*2.1mm DC plug, but this uses some other size I couldn't readily figure out. Still works great and as other users have noticed, is relatively quiet. Perfect for my small travel trailer.
Review: Great find! - This little beauty is perfect for our needs! I am allergic to cats, but have four (they were all adopted BEFORE this cat allergy emerged). We've set this up in our bedroom to reduce the amount of cat hair and dandruff around that make my eyes itch and water, and I've DEFINITELY noticed a significant improvement and the filter (which we empty and clean weekly) shows that it's gathering quite a bit of what we want out of the air! We run this 24/7 and the noise is barely noticeable to us. We hardly have ever used the sleep mode, but find that it is just as promised when we do. Over all, I'm planning on purchasing even more of these for other rooms in the house because it is a wonderful value for money!

## Features

- 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.

## Questions & Answers

**Q: I have a blinking power light which I assume the filter needs to be replaced. How does the machine know that the filter is replaced. Is there a reset?**
A: Hi there! When the Speed indicator keeps flashing in blue, it is a reminder to check and change the air filter. After replacing the filter, press and hold the sleep button for 5 seconds to reset the replacement reminder. If you have any problem, please feel free to contact us via support@airthereal.com.

**Q: How much are the filters?**
A: If and BIG IF you can find them as they are always out of stock….one filter is 20 bucks. Just one. Where as the purifier itself is only 40 bucks. Ridiculous

**Q: Can it be shipped to California? (prop 65)**
A: Hi there, yes, this model meets the CARB Certificate. It can be shipped to California.

**Q: How much power does it use in cigarette lighter mode?**
A: Hi there, we really appreciate your question. The power is 20W.

### ⭐⭐⭐⭐ No more irritated eyes at work
*by D***S on April 18, 2020*

Seems good as a desktop air purifier - my eyes are not as irritated and itchy after a day at my office desk. This is supposed to be a true HEPA filter unit, which may filter coronavirus, but I have no way of testing or verifying that. Nice compact size, easy to use. One drawback - it sucks in air on all 4 sides of lower half, but blows the air on the top, so I can’t direct the purified air towards my face. ( that is the recommendation for planes - to have the “fresh air” flow directed in front of your face to make a barrier against dirty air) Prompt shipment
