The thing is light (if needs to moved), quiet (on 'sleep' mode) and most importantly - works.
It consists of fan, plastics, filterpack, useless debile LEDs and useless debile electronics.
It needs of power button (have, work), and turn on button (have, work) - just the turnon is called Sleep mode. My house is 3 rooms in row, 16 sq.m. each, this thing works in the middle one. About 2-3 hours every day or so. It have ionizator function (don't use it, it will electrically charge all the atmosphere, if you happen to live at higher attitude with lots of oxygen, it will turn it to ozone, which later will poison or at least ultra-corrode everything. It is by no means chance that all the anti-aging chemicals are antioxidants, but the ozone is super oxidant. The other name of oxides is corrosion (especially metal oxides). And our blood have metals in it, even more as we are chemtrailed constantly with plenty of metal particles.
The filter-only function is perfect enough. It kills most of the usual light odours (foot, leather, ground from the vases, watery-moldy and so on. Also the ultra-fine debris (aka dust) is better filtered than by the air conditioners (which hold only the bigger particles).
Happy with the thing, considering buying for other places (the job, the courses afterwork, probably gift to some friends, etc).
It is not cheap (as price), so it is overpriced due to the full of useless electronics. But it is normal, we are all slaves to the panheads nowadays.Read full review
