EXERCISE FILTER

摘要

An exercise filter assembly (10) comprises a housing (12) with removable filters (36 and 46) and two one-way valves (50 and 62). The filters (36 and 46) remove any particulate matter three microns or greater from the air stream. The one-way valves (50 and 62), positioned in a unique manner, prevent undesired air flows from entering an individual's respiratory tract. The filter assembly (10) is comprised of a lightweight sturdy plastic which is easy and comfortable to wear.
