Citra Solv Air Scense is a natural air freshener made from essential oils and plant extractives. It comes in a non-aerosol pump spray in a recyclable aluminum can, with up to 3,000 sprays per 7 ounce can. If the pump stops spraying, pull off the nozzle, pump the inner tube up and down about 10 to 12 times, then replace the nozzle and prime it with a few pumps.
