Jodi-Consumer is a compact, portable, affordable hearing aid cleaning solution that helps keep your hearing aids clean. Take a few minutes each night or as often as you wish to ensure that you are removing wax in small amounts before they build up and require professional service. You do not need to see in these tiny openings; it is more of a gentle "feel your way" when vacuuming. Includes #19 needle for ITC, ITE and CIC hearing aids. Needles and filters not included under warranty.
