Airthereal ADH50B Air Purifier with 3 Filtration Stage True HEPA Filter for Small Room, Bedroom, and Office Whisper Quiet - Day Dawning

The picture is self explanatory.Its not 100% silent but not undesirable loud either.Small and compact.I will do an updated pic of a 3mth filter replacement to see if its as dramatic as the 6mths.

We like this small air cleaner for travel in smoky areas in our car.

I had written a negative review of this unit since it was defective and stopped working shortly after use.Jane from customer service had reached out to me promptly and very graciously help me get a replacement.She was very courteous and I was very pleased with customer service.The unit currently is functioning well in the car. It is quiet .One problem I have is how to secure the unit so it can stay up in the car, a problem during car movement, stop and go. The connector can be easily disconnected and the unit does not turn on automatically when the engine was started. It is difficult to see where the start button is since the screen is all dark without power.Thanks again Jane for your excellent customer service.

This works well for my small art studio space…but there is a hum to it, so I put on music to compensate. But it does clear the air nicely.

I bought my first Airthereal purifier 3.5 years ago because my roommate is allergic to cats and I have one. I use it often in my small bathroom because that is where I feed the cat; this little gem takes away the wet food smell within about 15 minutes of running (and that is with the wet food still sitting out). Today I purchased a 2nd one just because it works so well (1st one is still going strong!). It is super QUIET, very affordable and in writing this I am now thinking I should order a 3rd one........hmmmm :)

The product description shows that this unit is rated for a room of 160 square feet. However the product is only rated for a room of 110 feet.I would have rated lower However, it is a good purifier and it does very well in a smaller room.

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!

Easy to set up, and very aesthetically pleasing. Perfect size for a small/medium bedroom or office. Does it actually improve the air quality? I don’t know, but it gives a piece of mind. Compact and would be great to travel with.

Excelente producto para espacios pequeños. El filtro es muy bueno, durante el día en oficina no es ruidoso.
