Does an Oxygen Generator Require Water?

First, for most ordinary oxygen generators, water is not needed. This is tied to their structure and working principle. Generally, the most critical component of an oxygen generator is the separation device, which employs a physical adsorbent (such as zeolite molecular sieve). During the operation of the oxygen generator, the separation device separates nitrogen from ordinary air via physical adsorption and enriches the remaining oxygen for output. The entire process does not require water; on the contrary, thorough water filtration is necessary throughout the process to ensure the equipment operates efficiently and continuously.

There are probably two reasons why many people associate oxygen generators with water:

One is that in the early days, when the oxygen generator market was not yet mature, oxygen generators mainly relied on chemical agent oxygen generation or electrolysis of water for oxygen production.

Chemical agent oxygen generation involves adding chemical agents to the machine to produce oxygen through chemical reactions, but the oxygen produced contains many impurities and its concentration fails to meet medical standards. While electrolysis of water does use water, it not only suffers from the problem of impure oxygen but also has drawbacks such as long processing time and high power consumption. Thus, it has not been further developed technically. Currently, the oxygen generators available in the market are basically physical oxygen generators, namely pressure swing adsorption (PSA) oxygen generators.

The other reason is undoubtedly the confusion between oxygen inhalation and oxygen generation. When inhaling oxygen, a humidifier bottle is often used. After all, the oxygen from the oxygen generator is very dry (because water is filtered out), so it is necessary to put pure water or distilled water in the bottle to humidify the oxygen. This ensures a better user experience during oxygen inhalation, without the discomfort of dryness.
