The best way to care for my RiteFlo™ is to keep it away from young children. Before using the RiteFlo™, wash with soapy water and allow to drip dry. RiteFlo™ and other spacer/holding chambers are prescribed medical devices and not toys. It is best to wash the RiteFlo™ once a week in warm soapy water and let it drip dry. Do not wipe dry with a cloth or paper towel.
