The Oxy-Gyser is an astronaut’s best friend, it can be placed on a helmet, a wall, or mars outpost bathrooms stall because of its sticky backside. It is designed to be a small, compact fan device for filtering air, and adding oxygen to an environment. It stores oxygen from the earth and once its sucks in any harmful gas it replaces it with the oxygen it has stored. It can be turned on by the simple press of a button and can be turned off the same way; all that is needed to assemble is AA batteries so cost is minimal. It is recommended to equip an astronaut with 3 Oxy-Gyser filters so only a few need to be made at a time. I would appreciate if you took my idea in consideration for the Future engineers challenge. Thank you for your time.
