Incredible product, does exactly what it describes, makes a little noise, cleans the cigarette and odors in general, you really feel a clean atmosphere!
Very good machine and very high quality construction. In normal operation (auto), you can't hear anything at all. The fan will increase its speed when it detects a large amount of particles. In a few hours, the PM2.5 levels reached zero, confirmed by the awair monitor that is in the same room, which provides very accurate measurements.
It works correctly with home assistant and provides sensors for air flow, filter life remaining, particles, etc.
Finally, something that many forget, the price of the filters! In this machine, the 3-stage filter costs about 30€ and lasts 6 to 12 months depending on the pollution of the space. In other machines (e.g. winix), the price is more than double.
I have placed it in a smoking area and I can say that it makes a big difference. Of course, it needs to work at its maximum and it makes a little noise, but not to the extent that it is annoying. The filter will need to be changed around 1 year, so it's worth it.
I bought the air purifier as I live in a central area with a lot of dust and pollutants, and I have a pet at home. From the appearance of the filter, it seems to do a very good job with air particles, even though I don't activate the ionizer. I haven't noticed any difference regarding pet hair. I also read that it absorbs odors - I use it when I cook, but in this aspect, I haven't noticed any significant change. The connectivity with the app is very easy and convenient. In an environment with smokers, I believe it will do an excellent job!
