BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Individuals who are outside or exposed to various work environments can encounter a variety of air borne irritants. For example, walkers and joggers can be exposed to pollution, pollen, exhaust, insects, dust, smoke, bacteria, viruses, etc. There are also numerous other examples of individuals who are exposed to air irritants such as people who work in the sanitization industry, insect infested environments, dusty or sandy environments, painters, a chemical industry, construction workers, bike riders, skiers, fertilizing, crop dusting, exterminating and the list goes on. Animals and birds suffer as well from air borne irritants such as sand and dust including the other irritants and problems mentioned above which can lead to ailments such as lung disease. Moreover, negative effects are enhanced on individuals, animals and birds with respiratory conditions such as allergies and lung problems.
A variety of breathing filter devices have been available in the past, however, these devices have a variety of shortcomings, including devices which are too expensive to dispose of after one use or are not readily washable once they are covered with an irritant such as pollen, dust, mucus, devices which inhibit breathing, devices which are cost prohibitive, those which may not be sturdy specially in a moist environment, devices which are cumbersome to wear, the device may be unsightly to wear, etc.
The need therefore exists for a disposable breathing filter which is easy to apply, comfortable to wear, easy to remove, manufactured with inexpensive materials by an inexpensive process, disposable, washable, durable (especially for moist environments), lightweight, breathable, and yet warm.
SUMMARY
The invention provides a disposal nasal band filter designed to meet the needs mentioned above. The filter can be worn by individuals and animals.
The invention is to be applied to a user's nose and includes a filter element which seals around and surrounds the nostrils and two sheer adhesive strips which overlap the filter element and adhere to the user's nose. The filter element includes an elastic strand which is stitched around the outer edge of the filter element so that the filter element will grasp, seal around and snuggle the user's nose when the band is applied. Prescriptive or non-prescriptive medication can be added to the filter element allowing the filter to function as a Delivery System to the respiratory system.

DETAILED DESCRIPTION
Referring to FIG. 1, an individual 10 is shown wearing a DISPOSABLE NASAL BAND FILTER 20 over the nose 12. The DISPOSABLE NASALBAND FILTER 20 fits over the nostrils (not shown), adheres to the sides 14 and 16 of the nose 12, and snuggles above the apex 18 of the nose 12. When the disposable nasal band is in use, the individual is preferably close-mouthed 19 and is breathing only through the nose 12. The elasticity of the nasal band 20 enables it to snuggle the nose and to bulge or become bulbous to allow breathing space surrounding the nostrils (see also FIG. 3A).
Referring to FIGS. 2 through 5, the disposable nasal band 20 includes a central filter element or portion 22 which is preferably made of a thermal fleece or a thermal undergarment material. The thermal undergarment material is made from a well known waffle-woven knit having upraised
