Within half an hour it relieves my headache and nasal congestion from rhinitis. I stopped using Aerius indoors from the day I acquired it. I have it instead of a fan when I get hot. It gives off good coolness and I want to try it when the summer heat starts in case I can reduce the use of the air conditioner. In sleep mode, it is completely silent. I didn't expect to like it so much.

Very nice. I got it mainly for the dust and smoke.
However, its filter has a scent that bothers me

Beautiful, small-sized device, the sensor works very well, as does the application!
It's worth the money for small spaces

Dynamic particle control from the mobile. Fast cleaning of the room's atmosphere.
It really worths it.
Ideal for children's room and for those who have allergies.

In a room where I smoke, the air purifier does a good job and after an hour there is no lingering smell of smoke. I also leave it on all night and when I enter the living room in the morning, there is no smell at all. The living room is 55 square meters

The 4 stars only because it says 48 square meters and it is for 27, please correct it because you do not mention the actual coverage

It is completely silent, but it doesn't do anything about the odors. Indeed, the app says it covers up to 27 square meters, so in a 50 square meter house, I'm trying to close the doors. It does the job, but I'm not thrilled with the result. Initially, as soon as I connected it to the app, it said that the air quality was excellent! I live in the center of Athens!

I use it in the living room next to the cat litter box and I can say that it does a very good job. The reason I chose this one is purely because I read that it can be integrated into Home Assistant. In the end, I managed to do it, but the process was not easy at all as Xiaomi has made it very difficult to extract the API token. I won't go into details, but I eventually found the solution here, https://github.com/PiotrMachowski/Xiaomi-cloud-tokens-extractor/issues/43#issuecomment-1186615161. In my personal opinion, if you want it like me to integrate it with Home Assistant, get something else. Otherwise, make sure to use Xiaomi Miot from HACS because the official integration does not currently support this specific model.

Excellent air purifier. The result was evident from the first hour of operation. It only makes noise when it is at maximum power.
Attention, according to the instructions for use, it is for spaces up to 27 square meters

In a work space, a non-ventilated warehouse with strong odors from products, it has done an excellent job in the first week of use. Huge difference in eliminating odors and closing off
