The oxygen reservoir is a core infrastructure component of an EWOT setup. It requires a compatible oxygen concentrator and is intended for customers assembling or expanding a complete configuration.
While the reservoir can be paired with an existing concentrator, many customers ultimately choose a complete EWOT system because it integrates automatic reservoir fill capability. Without this integration, the concentrator must be turned on and off manually.
If you do not already have a compatible concentrator or prefer automated operation, a complete EWOT system may be the more straightforward option.
