Phew Pourri is 50% stronger than our fragrance mists and just 1-2 sprays will clear the average size room of the smelliest odors. The 4 ounce size is great for at home use and the 2 ounce size fits neatly into purse or pocket for outings. Whether its a stinky dog or a smelly rest room, Phew Pourri will do the job.
