Ear Planes - Child Size - EarPlanes are a patented pressure-regulating earplug inserted in the ear to help reduce discomfort often associated with air travel. They were developed by Cirrus Healthcare Products LLC in conjunction with the House Ear Institute in Los Angeles, and have been tested by US Navy aviators at the Miramar Navel Air Station in San Diego. The US Food and Drug Administration has designated EarPlanes as a "class 1" medical devise, and as such, they may be purchased over the counter without a prescription.

EarPlanes consist of two elements: a hypoallergenic silicone ear plug and a ceramic pressure regulator. The silicone earplug has four circumferential rings which provide an airtight seal between the product and ear canal. The ceramic element is a controlled porosity filter, one end of which is exposed to the external cabin pressure, with the opposite end exposed to the sealed chamber formed when the ear plug is inserted in the ear. Thus, as the cabin air pressure changes, a pressure differential is created across the ceramic filter, thereby causing air to flow through the filter. The filter acts as an impedance to the flow of air into and out of the ear canal.

EarPlanes are intended for people with sensitive ears or people who must fly even though suffering with a cold, allergy or sinus condition - not recommended in the event of severe sinus congestion (completely blocked Eustachian tubes). List Price: $6.45
