Super fast delivery! High-quality filter installed! Good service! Design not white / black as in the picture, but black / beige. Now the most important - I'm very strong and have allergic nature (unfortunately, birch) in front of the house. When the unit arrived it was just very bad. Quasi carried high with his last strength, connected and then I was completely finished on the ground. (Allergy among you will know that I am not exaggerating) After about 10 minutes it was better, after about 30 minutes. I was able to speak normally again and get up (without using asthma spray!) The marvel made it really the airborne pollen, in the room where it is operated, from the air filters. (Dusting .. better advance so that everything is in the air) Operated in the bedroom via silent "night mode" -Did slept wonderfully! I am very zufriedem with the device and its function! It improves my current quality of life in the apartment HUGE! Oh .. odors with Ozone function prima eliminated (fry to fish tried)
