Built around one nose: the one under a CPAP mask.

A CPAP machine treats sleep apnoea by pushing air through the nose all night. It does that job. What it also does, night after night, is dry and irritate the nasal lining, and a swollen lining is the reason so many people end up mouth-breathing against the pressure, chasing leaks, and pulling the strap off at 3am.

The fixes on sale for that are aimed at the mask or the air: cushions, full-face masks, chin straps, humidifier upgrades, decongestant sprays that hand the problem back three nights later. Nobody was selling anything aimed at the lining itself.

Plain language. We tell you what the device is, what the evidence for the category is and isn't, and who it won't help. We don't invent statistics, we don't publish reviews we haven't received, and we don't use the word cure.

Used with the machine, never instead of it. Nothing we sell replaces prescribed therapy, and we will say so on every page.

One device, 650nm red light, two soft removable sleeves, a ten-minute cycle. We specify it, test the units we sell, and ship them direct from the manufacturer, which is what keeps the price where it is and why delivery takes about a week and a half rather than two days.

60 days. Thirty days is long enough to know, and we would rather refund a device that didn't help than keep the money of someone who is still waking up tired.
