Hi, look, it is a nice air purifier....however, having a previous Ionmax. still have needs repaired, after cleaning does not wish to come back on, maybe just a switch... You could smell the negative Ions coming out of it, if in large closed room for few hours, smell was in the air a bit...:) A true lightening maker...air zapper...this one has the tube...sorry..but I do you a bit about all this ...they do not perform the same..and it is more difficult to have a tube or bulb put out Only negative ions...Ozone , mixed is not so good for human consumption,, in Australia, we have over abundance of positive ions...like over the top..5500 Positive per cubic meter to 320 negative is considered extreme imbalance, but quite often the case here....balance is 320 N to 280 P max....so, i have my concerns with this new unit..if I knew it was ozone tube,,,I would not have purchased it...the extra air filtering is nice to a degree, but you got to zapp the crap, mate...and I have to cover the blue light to sleep...so there ya go..and return comments are most welcome...
