Oxygen Purity
Oxygen purity is the percentage of oxygen in a gas stream compared to other gases such as nitrogen.
Oxygen purity indicates how concentrated the oxygen output of a concentrator is, usually expressed as a percentage. Concentrator output varies by equipment rating, flow, operating conditions, and maintenance. Filters and flow settings should be maintained according to the manufacturer's instructions.
This entry is part of the OxyEdge Hyperbaric Glossary, a plain-language reference covering pressure, oxygen delivery, and chamber construction. Understanding this vocabulary makes it easier to compare specifications, evaluate safety features, and ask informed questions before purchasing equipment for a commercial wellness business or home wellness space.
