I buy it at: https://www.amazon.com/Koios-Desktop-Purifier-Eliminator-Allergens/dp/B075H71QW9/?tag=xhai-20
This air purifier is better than I could have hoped for the purpose I bought it for! I have it in a bathroom that has a very stinky cat box no matter how clean I keep it, and the bathroom was right next to the entry where ANY bathroom odors could be smelled. Not exactly the reception I was looking for of coming to my house. I set this up, closed the door, and left the room so I could have a real test. I came back in in 2 minutes, and the room was fresh! I wouldn't expect at this price point to do your living room or anything, but for this size room, probably even a bedroom, I am so impressed.I showed in the video, the 2 different speeds so you can hear it, but it is definitely quieter than my bigger Dyson, and I feel it works better.
