People with allergies, asthma & chemical sensitivities struggle with balancing the need of clean oxygen (via concentrator or tank) with the competing pocketbook and logistics of being able to attain/afford hypoallergenic tubing that is not only latex-free (most is) but also polyvinyl chloride-free (very difficult to find, even on the web). If/when you Do locate a source, chances are it is $10 a ft. Tubing must all be replaced appx. every 2 wks. The pthalates necessary for flexible tubing are one object of the PVC controversy, and special labeling of DEHP PVC is already being required by regulations in Europe. To be affordable by those who need it. PVC-free tubing would require Medicare-compatible rates. Many people are already going without... without the oxygen needed.
