An ear irrigation kit is used to safely flush out excess earwax, foreign debris, or other blockages from the ear canal using water or saline. These kits typically include a syringe or a bulb for controlled flushing, tips to direct the flow, and sometimes wax-softening drops or an air blower for drying. They are used for home care to relieve symptoms like muffled hearing or ringing in the ears caused by buildup.
