From the moment your kit arrives to the first deep breath of the night. A complete walkthrough — including how to find your size, how to apply, how to care for your band, and what to do if something feels off.
Take your time the first night. Once you've found your size and learned the press, application becomes a 30-second habit you do without thinking — somewhere between brushing your teeth and turning off the light.
Your kit ships with four bands — Small, Medium, Large, Extra-Large — designed to fit 99% of adult noses. The right size feels like nothing once worn. The wrong size feels too tight (pinching) or too loose (slips with movement).
To find yours, fit each unworn band gently over your nostrils as a "bull-ring test" — like jewellery, not adhesion. The smallest band that touches both nostril openings without pressing them closed is yours.
Most users land on M or L. If you're between sizes, choose the larger one — the magnetic anchoring compensates for slight looseness, while too-tight is uncomfortable for nightly wear.
Skin oils and moisturisers are the number-one reason adhesives fail. One alcohol-free micellar prep wipe (included in your kit) clears the placement area in 10 seconds. Pat dry. That's it.
If you wear moisturiser, sunscreen, or makeup during the day, prep is essential. If you've just washed your face, you may still want to prep for maximum hold — the residue of even gentle cleansers can reduce adhesion by 30%.
Prep both placement spots — one on each side of the nose, just below where the nostril meets the cheek. The tabs anchor to skin, not cartilage.
Press a fresh adhesive tab firmly to each side of your nose — hold each for a full 10 seconds. The band then clicks into the tabs magnetically. You'll feel the first deep breath open within seconds of the magnetic seat.
Wear through the night. Side sleepers, hot climates, and humid summer rooms are all fine — the magnetic anchoring was specifically engineered for that range. In the morning, lift the band off (tabs stay on skin), then gently peel each tab. Discard tabs; the band returns to your case.
The first wearing may feel slightly odd — like noticing your tongue in your mouth. By night three, you'll forget the band is there. Eight in ten new users describe the first morning as "the most rested I've woken up in years."
Every Starter Kit includes all four sizes so you can find your fit on the first night. Replacement single-size bands are available once you know yours.
Narrow nasal valve. Common in younger adults and some women.
Most adult women, smaller-framed adult men. The most common size we ship.
Most commonMost adult men, broader-nosed adult women. Equally common.
Most commonBroader nasal structure. About 8% of our users land here.
Choose the larger one. Magnetic anchoring compensates for looseness; tight is uncomfortable for nightly wear. If neither size feels right after a week, write to support — we'll send a custom intermediate size at no charge.
Aira is a daily object, like a wristwatch or a wedding ring. It asks for very little — but the little it asks keeps it performing at full strength for the full six-month life of each band.
A 10-second rinse keeps the band ready for tonight.
Once a week, or when the band feels slightly tacky.
The tabs are single-use — replace after every wear. Your Starter Kit includes 30 tabs (one month at nightly wear). The band itself lasts approximately six months of nightly wear before the magnetic anchoring weakens. Subscribers receive automatic band replacement reminders at the six-month mark.
Most issues resolve within the first three nights as your skin adjusts to the adhesive. Here are the five most common questions from new users.
The first night is the hardest. By the third, you'll have forgotten any of this was complicated at all.
