Anyone heard of this? It's supposed to be the best/only proper way to get rid of the bacteria and therefore cheesy smell from aircon systems but it only seems to be available in Europe from what I can see. Tried a few things now, and nothing works completely. It'd be nice if I could find a company who would guarantee that the smell wouldn't reappear for, say, 6 months after treatment, just to prove it works, cos most of the time it seems the smell returns after a few months and nobody seems bothered by that point. Car bombs are pretty rubbish and you have to ask if a company is using them or not even when they spout about a full cleansing!

 

Opinions?

Ozone is very effective. Aircon service engineers use something like this http://www.naasltd.com/online-shop/specia-tools/product/lovair-auto
