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 is Hostage Tape 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 is Somnifix the right pick?
If you want FDA-registered (a listing, not clearance or approval) mouth tape with a porous design — Somnifix is the right shape. Multi-year track record.
When is Intake Breathing the right pick?
If you can't adapt to mouth tape — Intake is the right shape. Premium external magnetic dilation, James Nestor-recommended. Dilators can also quieten snoring and hide possible sleep apnea — if apnea is possible, see a doctor first.
