Recommendation: Do not reuse after two flights since pollen, dust, and moisture will reduce effectiveness.

As cabin pressure changes the filter acts as impedance to the flow of air into and out of the ear canal. Clean earplugs with mildly damp cloth; do not get water or debris in the cylindrical cavity of the plug as this may cause the liner to fail. EarPlanes Ear Plugs offer ear pressure comfort on take-off and landing of aircraft as well as noise reduction. Navy aviators at the Miramar Naval Air Station in San Diego have also tested these ear plugs for effectiveness.These ear plugs were developed and tested by a specialist ear institute in the USA (House Ear Institute) and by US Navy sailors. EarPlanes may be removed when the airplane reaches maximum altitude and reinserted one hour before landing. These drug-free ear plugs are designed with smaller ears in mind, making them ideal for children ages 1 to 11. Earplanes help relieve ear discomfort, clogging, and popping by naturally filtering and regulating air pressure with its exclusive ceramx filter.

These amazing ear protection plugs have been specially designed to offer ear protection against air pressure discomfort and clogging/popping during altitude changes.EarPlanes for Kids can be removed when the airplane reaches maximum altitude and reinserted one hour before landing. Weather changes used to be something that I knew would trigger a migraine but had no way of protecting myself against, especially living in the midwest where we can experience all four seasons in a weeks time. During take-off and landing of a flight the CeramX™ filter slows the shift of air pressure that enters your ear. While the primary purpose of EarPlanes Children's Ear Plugs is to minimize discomfort caused by cabin pressure changes, the ear plugs also act as noise-reduction devices. Chronic sufferers can insert them just before takeoff and remove them when the airplane reaches maximum altitude, reinserting one hour before landing.
