Hi everyones...thanks to read! I have the Alpine Living Air Classic (xl-15) air purifier and since a few months, i've noticed that the ozone output is greatly reduced, and for what remains, the smell is...well... not the same it used to be (compared to another machine with new plates a friend bought). On my machine, i do clean them once a month (did it yesterday) as usual, using water/ammonia as recommended in the user's manual and on many web sites. Please look at this picture i took yesterday:
Despite a good cleaning, the foggy substance remains under the screens. I think it's the reason for their reduced effiency. I'll buy two new ones shortly. I don't know if the ceramic plates are better regarding this issue (i know nonetheless that they're less fragile than the glass ones). To go to the point, i would like to know what causes this foggy film to build on the glass over the months (years?). This relates more the chemistry than electronics, so i'm kind of lost here! ;-) TIA for any replies.
