As such an ionizer is a good idea and would actually make sense especially in toilets, closets and shoe shelves. But also for example in the small office where every day running around the clock of the PC and printer. However, this ionizer missed the full meaning and purpose. This is especially the fact that it turns off after just 10 minutes! What the manufacturer has been thinking in God's name? What should one expect a miracle in just 10 minutes from such a small ionizer ??? Sorry but what Dumkopf has come up with that? I mean if it was shut down at least 30 minutes, it would be useful but if I eg in the bathroom using it after a bowel movement, and turns off after already 10 minutes, then it smells clearly still after bowel movements! OK my bathroom is not the smallest (10-15 square meters) but I can not ever remember every 10 minutes 3-4 times to go to the bathroom, to press the button on the ionizer !! In the study (about 20 m²) I can press at least at the end of the 10 minutes, because I'm in the room and can strike me, to turn again. I can then make several times until the coast is clear. Now I have it in the store room used (3-5 m²), is located shoes, vacuum cleaner and a trash bag for plastic & plastic. At least because it makes a little sense, because I already after 10 minutes had clean air in it.
Conclusion: possibly for extremely small spaces / limited suitability. Otherwise not timed completely useless!
My suggestion for the producer: increasing Instead of 10 minutes 20 or 30 minutes. Better: Timer setting so that you can enter at which times how long it should activate itself. Such "extras" do not really cost a lot of money!
SUPPLEMENTARY 07/06/2015: Now it is completely broken! Only the LED lights lit but heard no Betriebsgeräuch. At my request to the seller (so far) no answer!
