Tag: Oxygen purity

While the oxygen gas inside an oxygen tank does not technically expire, its purity can degrade over time if the tank's integrity is compromised. Understanding the crucial difference between the gas's stability and the physical tank's service life is key to answering how long do oxygen tanks last before they expire.

While the air we breathe contains only about 21% oxygen, supplemental options like Boost and medical oxygen offer higher concentrations. Understanding **what's the difference between Boost Oxygen and medical grade oxygen** is crucial for safe and appropriate use, as they are not interchangeable products.

By mass, water is comprised of nearly 89% oxygen, a surprising fact considering our atmosphere contains only about 21% of the life-sustaining gas. Understanding **what is the highest percentage of oxygen** requires exploring different contexts, from chemical composition to pure, medical-grade gas.
