Review on Air purifier/humidifier with aroma function BORK Q710, black by Celina Jasiska ᠌

I agree with Alena. Premises - bedroom, 22 sq. M. Q710 according to the pport is designed for 40 sq. M. t=26 C. Winter. Batteries are fire. Pvc windows, tightly closed. The device was placed in different places in the room. Bought this air washer. The weather station showed 15%, after turning on the Bork Q710, the weather station recorded 21%. This Q710 was running at full capacity. Moreover, the Q710 panel displays 40-43% humidity. It seems to me that this is either a divorce, or the humidity sensor is inside the device. Didn't feel a difference in the bedroom at all. I want to return this miracle unit. For me it is better to open the window and ventilate the room. Outdoors 70%, indoors should be 35-40%, no more than 60% (according to GOST "Indoor microclimate parameters"). By the way! For air washing. If you bring your palm to the place where the device in air, you will understand that the thrust is not so great. It seemed to me that the device can clean the air located half a meter from the suction hole. Accordingly, in order to draw air into the device from the corner of the room, the device simply does not have enough relics. I understand that for this there must be a powerful unit that is not suitable for residential premises. But! If all the windows are closed, everyone is seated in their places, then how can the air completely mix and reach the cleaning device? And even more so at night. At night, the air flow velocity is generally close to zero. The device operates at minimum power so as not to make noise. And what does he clean then? air a meter away? With the help of the device, the air became 5% more humid. I think that the device can not cope even with a room of 22 sq. M.
