During early training, users notice that the +O2 air (high oxygen) smells very fresh and nice while the hypoxic air is warm and less pleasant. Over time they notice that the sensation of breathing the hypoxic air changes to be more desirable.
There are 3 reasons for this:
- User conditioning enables more comfortable exertion using low-oxygen air;
- Oxygen-rich air always smells fresh because it is processed by a molecular sieve which prevents all molecules larger than O2 from passing. The filter is literally small enough to reject N2, or nitrogen gas from passing. This means all environmental agents that can cause odor will be filtered out of O2 source;
- Any environmental odor agents larger than a O2 molecule will concentrate in the ‑O2 gas. This often enables the user to “smell” more from the environbment because the air separation process concentrates these substances.
Our normal training has beginner users breathe mostly oxygen until they improve their general conditioning. This usually means most users do not use the hypoxic ‑O2 air source until the air separator unit has run for over 20 hours.
Users who would like to use higher levels of ‑O2 may prefer to run the air separator for 24 – 48 hours before doing protocols that rely on primarily hypoxic ‑O2 air. has early users.
This run time enables the air separation unit to completely flush out manufacturing residue. Our manufacturing burn-in is 5 – 8 hours.
