Oxygen Concentrators VS Oxygen Cylinders

* Oxygen cylinder can start leaking, creating an environment where the air is saturated with pure oxygen. Air that is enriched with oxygen increases the risk of fire. Because oxygen-induced fires burn hotter and faster than other fires, it is more difficult to put them out. Oxygen concentrators use the surrounding air and create purified air as needed; there is no risk of leakage, thus reducing the risk of catching fire immensely.
* Oxygen concentrators are preferred in part because of their convenient size. Tanks are frustratingly bulky and heavy. Oxygen concentrators are with small size and easier to operate.
* Buying an oxygen concentrator will, over time, be more financially responsible. Yes, buying a concentrator means a large upfront cost (and, with continued use, replacement filters, and nasal cannulas), but that price is typically less than all the costs incurred with replacement cylinders.
