Filtration for my new tan salon?

[hannahjacka]

Hi Im from Australia.
What type of filter (or anything else) do you guys use for your spray tanning rooms?
the one im currently going into has 3 booth type rooms. I need to work out whether to get exhaust in the roof (may be impossible) or a type of air purifier? I know theres some tanning companies that sell these set ups but they are so so expensive and at the moment i dont have the budget for something worth thousands of dollars.

Thanks!
