The short version
Three category-defining nasal-breathing aids, three different theses. Hostage Tape = beard-friendly biohacker mouth seal. Somnifix = FDA-registered porous mouth tape. Intake = premium external nasal dilator.
When Hostage Tape is the right pick
If you have a beard and want subscription-convenient biohacker-brand mouth tape — Hostage Tape is the right shape at lowest annual cost.
When Somnifix is the right pick
If you want FDA-registered medical credibility with porous safety design that allows emergency mouth exhale — Somnifix is the right shape. Multi-year track record.
When Intake Breathing is the right pick
If you can't adapt to mouth tape or you want lower-risk entry with no sleep-apnea contraindication — Intake is the right shape. Premium external magnetic dilation, James Nestor-recommended.
