Two tools, one job: both nasal strips and nasal dilators exist to open the nasal valve, the narrowest point of your airway, so nose breathing takes less effort. One works from the outside, one from the inside, and which suits you comes down to comfort, context and how your nose is built. We make strips, so read this knowing that, and know that dilators genuinely win some of the rows below.
How each one works
External nasal strips are adhesive bands with springy inserts, worn across the soft part of the nose. The spring wants to straighten, gently lifting the nostril walls outward from the outside. Nothing enters the nose; the strip peels off in the morning.
Internal nasal dilators are small frames, cones or magnetic clips, usually silicone or plastic, that sit just inside the nostrils and push the walls outward from within. They are reusable, typically washed after each use, and replaced every few months.
Both approaches are drug-free and mechanical, and published work on external dilation reports reduced nasal airway resistance; we cover the evidence for nasal strips in detail separately. Our strips give up to 35% more airflow versus no strip, individual results vary. Internal dilators produce comparable airway effects in studies; the meaningful differences are practical, not physiological.
The honest comparison
Sensation. The biggest fork in the road. A strip is felt as a gentle outside pull that most people forget within minutes. A dilator is felt as an object inside the nostrils, and while some users stop noticing it, a solid minority never do. If you know you dislike things in your nose, this row alone decides it.

Hold through the night and through sweat. A well-applied strip with a sweat-resistant adhesive is designed for up to 12 hours of wear; its failure mode is adhesive-related and mostly preventable with clean, dry skin. A dilator cannot fall off, but it can migrate or be pushed out, and side sleepers sometimes dislodge them against the pillow. Call this row close, with the edge depending on your sleep style.
Hygiene and upkeep. Strips are single use: fresh every night, nothing to clean, more packaging. Dilators are reusable: washing required, and skipping it invites exactly the bacteria situation you would expect from an object worn inside the nose nightly. Discipline decides this row.
Cost. Dilators win over time: a $20 to $40 dilator used for months beats any consumable on dollars. Strips run about $0.56 to $0.83 a night with us. If price per night is your deciding factor, dilators are the honest answer; strips buy you the fresh-every-time, nothing-inside-the-nose version of the same mechanics.
Skin vs nostril sensitivity. Strips ask something of your skin: a gentle, skin-friendly adhesive reduces the risk, but sensitive skin may want nights off. Dilators ask nothing of skin and everything of nostril tolerance, and sizing matters, because a poorly fitted dilator is somewhere between useless and genuinely uncomfortable.
Visibility. A strip is visible; athletes have made it a badge, but at a dinner party you may feel otherwise. A dilator is nearly invisible from the outside. If discretion matters, dilators win; if you train in one, nobody blinks anymore.
Who suits which
Choose a dilator if cost per night rules, you sleep on your back, you are disciplined about cleaning, and things inside your nose do not bother you. Choose a strip if the thought of an in-nose device is a dealbreaker, you sweat through sessions or warm nights, you want zero upkeep, or you simply want the version you will actually keep using, because the best airway tool is the one that gets worn. Some people keep both: strips for training and travel, a dilator for home.
If your real problem is breathing through your mouth at night rather than a narrow nose, that is a different comparison; see nasal strips vs mouth tape for that one.
Neither treats snoring's many causes and neither treats medical conditions, including sleep apnoea. If your snoring is loud and chronic or comes with gasping or pauses in breathing, see your doctor before buying anything from this category.
Frequently asked questions
Are internal nasal dilators better than nasal strips?
Neither is better outright; studies show both reduce nasal airway resistance. Dilators win on cost over time and invisibility; strips win on comfort for people who dislike in-nose devices, on zero upkeep, and on sweat-heavy use.
Can you sleep with an internal nasal dilator?
They are designed for it, though side sleepers sometimes dislodge them and they must be cleaned after use.
Do nasal strips and dilators do the same thing?
Yes; both mechanically widen the nasal valve. One pulls from outside, one pushes from inside.
Which is more comfortable?
The one whose sensation you tolerate better: an outside pull you forget, or an inside object you may or may not stop noticing. There is no universal answer.
Can I use a nasal strip and a dilator together?
Physically yes, and a few people do, but most get what they need from one. Start with one, judge after a week.
