P-Wave Easy Fresh Fan Air Freshener Dispenser is an innovative non-aerosol air freshener device. This fan unit features interchangeable fragranced covers, which effectively disperse highly scented air evenly across the room. With a single fan unit, it can cover an impressive area of up to 16 square meters. The batteries have a lifespan of up to 6 months, while the covers last for 30 days. Attaching and removing covers is a breeze with the simple clip-on/clip-off mechanism. Operating silently, this dispenser offers superior coverage compared to aerosol air fresheners, delivering a continuous and delightful fragrance without abrupt bursts.
