What is the EWOT TESTING program?

The fact that oxygen therapy works has already been extensively researched and described in numerous scientific studies, so testing is no longer necessary in that sense. However, with the EWOT Testing program you will have the opportunity to experience EWOT oxygen therapy for yourself for 8 weeks before you finally buy the EWOT set.  We hope you take advantage of this period and discover that there are there is no reason to withhold EWOT from your health.


For the test, only the EWOT multistep set with the 5 liter oxygen concentrator is available as a new device in the original scope of delivery without additional accessories. If the  Oxygen Therapy Kit is accepted after the test, you only pay the processing costs for the test option, and we deduct the test costs from the total purchase price.


If you decide not to take over the EWOT oxygen system, you will only pay the testing and processing costs. Of course, the test can be stopped at any time during the eight-week testing period. In that case, the testing and processing costs will not be refunded.
