One question I would have when the sleep mode is running, then run the ionizer ???
Initially I was a bit on the extreme over strong positive comments from L.Garnier skeptical, especially why a customer then At length a particle analyzer and tens of devices tested. Just as such a device costs about 3000 euros but no matter for whatever reason :) To each his hobby ^^
It seemed but a bit like a professionally packaged advertising, so I can not say how other devices are compared and should probably think so. Personally, I can only say that the device very well suits me, of something strange plastic smell like another customer describes I feel well, so I mean, but the smell of the ionizer's because they always smell a bit peculiar, which can of course point to chlorine !
The ozone I let out personally, it stinks terribly easy and fast does not volatilize that! So for me it has after 10 hours still smelled after 15 minutes of ozone use.
But now the most important:
I'm allergic to pollen with me the device runs from 08:00 - 21:00 clock in the living room every 40 minutes / 20 minutes rhythm and when I am at home on stage 1. At 21:00 clock I add the device to the bedroom then let it run 2 hours to level 3, then in the sleep mode. (Which is whisper quiet!)
The pollen allergy is itself in dire months now bearable once I'm at home in the air clean rooms I feel better minute by minute, of course, I then builds during the day in the open air again on something but so get on well through the day.
What a little annoying is actually just the display.
There are 5 star out of 5 because what I expect from the device "air cleaning" works perfectly! You can make ozone, ions also can display any normal mortal seal of it in the bedroom.
