It sounds as though what you need is a PAPR, Powered Air Purifying Respirator. Has a device that rides just above your hips with the air filtration unit pulling air in with the help of a battery operated pump and then the air flows to the full face respirator mask. If you were to try to buy a SAR, Supplied Air Respirator, you would need some very expensive hose, face mask, and a rented tank of breathing air. See if you can find a safety supply house in your area that carries PAPR's. If there isn't one you might try on the web to find one with a Google search. Be aware that such a device is not cheap though. A normal APR, air purifying respirator is only 9 or 10 bux but the others can run from $600 to over $2,000.00. None of them use oxygen, just normal ambient air, either drawn in through a cartridge that filters the air or by the power of the small motor air is pushed through the filter. The others, SAR and SCBA (Self-Contained Breathing Apparatus) use compressed breathing air, known as Grade D breathing air, and are only good for the length of time the bottled air is used. Basically, if you're unable to use an APR you're looking at an expensive proposition.
