How does DELIM mouth tape work?
DELIM mouth tape is a soft, hypoallergenic strip designed to gently encourage nasal breathing while you sleep. Nasal breathing filters and humidifies every breath, supports deeper sleep stages, and protects your oral microbiome — without devices, apps or pills.

Are you a mouth breather?
Most people who breathe through their mouth at night don't know they do. The signs are easy to miss — and easy to fix. If any of these sound familiar, mouth tape is built for you.
You wake up with a dry, sticky mouth.
Your saliva dries out, your oral microbiome takes the hit, and you start the day already dehydrated. Mouth tape protects both, every night.
You snore — or your partner has been telling you so.
Mouth breathing causes the soft-palate vibrations behind most snoring. Encourage nasal breathing and the bedroom gets noticeably quieter — usually inside the first week.
You sleep eight hours and still wake up tired.
Without nasal breathing, you skip the deep stages your body needs to recover. Mouth tape supports the kind of sleep that actually leaves you feeling rested.
One simple fix, six nightly wins.
DELIM mouth tape supports nasal breathing — the way your body was designed to breathe at rest. The downstream effects compound: deeper sleep, calmer mornings, fewer dry-mouth wakeups, a quieter bedroom for whoever you share it with.
Mouth breathing is a leading cause of snoring. By gently encouraging nasal breathing, DELIM mouth tape reduces the soft-palate vibrations behind most snoring — so you and your partner finally get an unbroken night.
Your nose filters, warms and humidifies every breath, while raising nitric oxide — a natural antimicrobial. Mouth breathing skips that protection. Nasal breathing tape gently restores it.
Chronic mouth breathing reshapes the face over years — narrower jaw, longer profile, slacker lips. Nasal breathing supports the natural posture your face was built for.
Better breathing means deeper sleep stages — and that means real recovery. Customers tell us the brain fog they'd lived with for years is the first thing to go.
Mouth breathing dries out your saliva and your oral microbiome overnight. Close your mouth, protect them both, wake up actually refreshed — not parched and sour-tasting.
Slow nasal breathing nudges your nervous system into rest mode. The result is the kind of sleep that doesn't just last eight hours — it actually feels like eight hours.
The mechanism behind the 80%.
Three steps, one night.
No bulky devices, no subscriptions you can't escape, no kit cluttering your bedside. One small strip, placed horizontally. That's the entire routine.
Clean, dry lips.
Before bed, a quick wipe with a flannel. No lip balm, no moisturiser — the tape holds best on clean, dry skin.
Place horizontally across the lips.
Just enough to gently encourage your lips closed — never forced. The skin-safe adhesive peels away the instant you need to open your mouth, so you stay in control all night.
Breathe through your nose.
Fall asleep, breathe naturally, wake up quieter and more rested. Peel off gently in the morning — even on facial hair, no pulling.
First week? Start easy.
New to mouth tape? Wear it for an hour or two on the sofa first, then a full night. Most sleepers adjust by night three. There's no wrong way.

A British mouth tape, properly done.
Every American mouth tape brand we tried felt generic, cost a fortune in customs, and treated UK shoppers like an afterthought. DELIM is built around how the UK actually shops, ships and sleeps.

UK reviews
"We built DELIM because every piece of mouth tape we could buy in the UK was shipped in from America, cost a fortune in customs, and felt generic. A small strip deserves better design — and British sleepers deserve a brand of their own."
Bedrooms across the UK.
Thousands of nights, one tiny strip. Photos sent in by DELIM customers — unedited, unposed, and proof that better sleep starts with one small habit.
DELIM works for most people — not all.
Mouth tape only works if you can comfortably breathe through your nose. Read this before you order — we'd rather you skip the purchase than have a bad first night.
