Abstract:

A protective helmet for wearing while riding an open-air vehicle, such as a motorcycle or all-terrain vehicle. In addition to protecting the head from being injured in a collision, the helmet prevents particles of dirt, dust and similar debris from reaching the face of the helmet wearer. The helmet includes one or more removable filters which cover one or more air intakes ports formed in the helmet, and which are sufficiently porous to allow adequate air passage therethrough. Each filter is coated with a benign adsorption substance, such as vegetable oil, which captures the particles and prevents them from passing through to the rider, and which does not clog the filter pores. A filter with these characteristics also may be used in other applications, such as with air conditioners, carpentry dusk masks, and the like.
