Our candles emit a noticeable aroma in your space, but it will not be as strong as a spray-type air freshener, or a candle made with petroleum-based wax (paraffin) or synthetic fragrances. As with most plant-based wax candles, the scent becomes most noticeable after burning for approx. 1 hour.  The longer the burn, the stronger the scent will become.  Never burn a candle for longer than 4 hours at a time.
