O-Zone generator hire/treatment

Hi guys, 

Interested in having our cars ozone treated to get rid of the smokers smell in the Superb and the slight mould in the Fabia (it needs a spruce up!)

Does anyone know of a detailer or company that rents/provides treatments? 

I have found a ton of companies in the US doing it or flood/fire restorers in the UK (but are expensive). 

Thanks
