Salts Fresh Aire Odour Eliminating Spray 50ml Unlike many other air fresheners & deodorisers, Fresh Aire doesn't just mask unpleasant smells with perfume; instead, it attacks & destroys the odour molecules completely, so that the odour can't come back. Fresh Aire is effective & easy to use. During pouch changes, Fresh Aire is simply sprayed once or twice into the air around the pouch.
