Sleep Karma Review (2026): Our Top-Rated Mouth Tape
We tested Sleep Karma over 7 consecutive nights, analyzed hundreds of customer reviews, and compared it against 45 other brands in our 46-brand database. Here’s our in-depth review.
Sleep Karma Mouth Tape. Top-rated mouth tape in our 46-brand database.
Sleep Karma Mouth Tape
The highest-scoring tape in our test at 8.9/10. Sleep Karma reports its adhesive is lab-tested to ISO 10993 (brand-published; not an Evident lab test). It held through our nights and came off without residue.
Mouth tape isn't a treatment for sleep apnea. If you snore heavily or gasp or choke in your sleep, get assessed first; don't tape with a blocked nose, and don't use on children without clinician guidance.
We built Sleep Karma after researching 46 mouth tape brands. Sleep Karma is scored on the same criteria as every brand. 46 brands researched and scored, 7 recommended. If you’d rather choose a brand we don’t own, see the full rankings — VIO2 (7.8), MyoTape (7.5), and Dryft Sleep (7.3) all scored well. Sales of Sleep Karma help fund Evident Reviews’ testing and research. We own Sleep Karma — disclosed on this page.

What Is Sleep Karma?
Sleep Karma is a premium mouth tape brand based in Brooklyn, NY, designed to help users restore natural nasal breathing during sleep. Founded by a team obsessed with materials safety and sleep physiology, the brand was born out of frustration with the lack of transparency in the mouth tape market — particularly around adhesive ingredients and published safety testing.
One of few brands that publishes adhesive lab testing. Sleep Karma reports its adhesive is lab-tested to ISO 10993 (brand-published; not an Evident lab test).
The product uses an ultra-thin bamboo silk fabric paired with a medical-grade adhesive. Sleep Karma reports its adhesive is lab-tested to ISO 10993 (brand-published; not an Evident lab test). It comes in two formats: a full-coverage strip (3.5" x 2") that seals the entire lip area, and slim profile strips for users who prefer a more minimal fit. Both are designed for all-night hold with gentle morning removal.
Sleep Karma ships from US distribution centers on both coasts, offers a 90-day money-back guarantee, 24/7 customer support, and a subscription model that includes periodic gifts. The adhesive is sourced from Henkel in Germany, and no PFAS was detected in third-party testing.

What We Found
What we liked
Adhesive lab-tested to ISO 10993 claim. Sleep Karma reports its adhesive is lab-tested to ISO 10993 (brand-published; not an Evident lab test).
Bamboo silk material. Thinner, softer, and more breathable than non-woven synthetics. Zero irritation after 7 nights. Drapes naturally rather than pulling or bunching.
All-night hold, painless removal. Stayed in place every night as a side sleeper. Peeled off cleanly every morning — no residue, no skin-pulling. No trade-off between hold and comfort.
Full coverage, no vents. The 3.5” × 2” strip seals the entire lip area. No air escape path. Works with facial hair.
Total ingredient transparency. Adhesive supplier (Henkel, Germany) and exact composition are in the brand file. Rare in this space.
90-day guarantee + extras. 24/7 support, no-questions-asked returns (less than 1% claim rate), plus a bamboo holder, ear plugs, and travel case for subscribers.
Our concerns
Price. One-time price is $49.95 for 30 strips ($1.67/night). Subscription is $34.97/month, and the 6-month plan is $0.83/night.
Adhesive variability. A handful of reviews note slight differences between bags. Airing strips briefly before use helps.
Online only. Sold exclusively through sleepkarma.co. No retail option. The 90-day guarantee offsets the risk.

Our Verdict

What Reviewers Are Saying
Sleep Karma carries a 4.9-star average across 343 reviews. Among verified purchasers in brand and Trustpilot reviews, most say they would recommend it and that the tape stays on overnight. Those are customer opinions — not clinical proof of better sleep.
“I’ve tried four different mouth tapes and this is the only one that stays on all night without irritating my skin. The bamboo material feels completely different from anything else I’ve used.”
“Was skeptical about mouth taping but the 90-day guarantee made me try it. By night three I was still using it. Comfort is a customer opinion, not a clinical result.”
The most common praise: comfort and adhesive safety. The most common critique: price.
