Is there a device that ozone-ises or ionises the air to reduce the odour that builds up in an unventilated bathroom?
I'm not talking about reducing smells created by - eh - "toilet deposits", more the smell that builds up because there is exposed water in an unventilated room.
Update This is indeed an infrequently used bathroom, in my inlaws basement. I need to do some wiring work down there and thought if there was a device I could wire in to help I'd do so. I thought I'd seen things in bathrooms in Pubs & Restraunts that does this, possibly not.
