For anyone dealing with a deviated septum, the nightly struggle to breathe through a blocked nostril is frustrating. Nasal cones, also known as internal dilators, offer a drug-free alternative to adhesive strips by physically propping open the nasal passage from the inside, allowing for deeper, quieter sleep without the skin irritation that strips can cause.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent countless hours analyzing the raw material specs, customer feedback, and design variations among internal nasal dilators to separate the truly effective designs from the ones that fall out halfway through the night.
This guide breaks down the top options for internal nasal support so you can find the best nose cones for deviated septum that match your anatomy and sleeping habits.
How To Choose The Best Nose Cones For Deviated Septum
Not all internal dilators are created equal. Choosing the right one depends on your nostril shape, whether you sleep on your side, and how much structural support your septum requires. Here are the critical factors to consider.
Material and Flexibility
The most comfortable dilators are made from soft, medical-grade silicone or a flexible thermoplastic polymer. These materials conform to the nasal anatomy without causing pressure points. Harder plastics can dig into the septum over time, while overly soft materials may not provide enough lift to keep a collapsed nostril open.
Design and Retention
The best designs use a spring-like mechanism (either a flexible bridge or circular flares) that gently expand the nostrils outward. For side sleepers, a low-profile or contoured shape is critical to prevent the dilator from being dislodged against a pillow. Look for models that feature a ribbed or textured surface for grip inside the nasal passage.
Size and Fit Customization
“One-size-fits-all” dilators rarely work for deviated septums. A good product offers multiple sizes or a flexible design that can be trimmed. If you have a narrow nostril on one side, a smaller cone or a dilator with an asymmetrical design can balance airflow without causing discomfort.

In‑Depth Reviews
1. SleepRight Intra-Nasal Breathe Aids (2 Pack)
The SleepRight 2-pack offers the highest performance for serious septum issues. Its flexible nasal flares use a spring-like action to expand nostrils up to 58%, creating immediate, noticeable airflow. Users report that this model stays securely in place even for side sleepers and those using a CPAP mask, which is a significant advantage over less robust designs.
The pack contains four pieces (two single-use sizes), ensuring you always have a clean dilator while one set dries. The initial two-week adjustment period may cause minor nostril soreness, easily managed with a lubricant like petroleum jelly. Once accustomed, users note an extra hour of deep sleep and elimination of morning dry mouth.
Each piece is rated for 15 days of reuse, making this a premium option for long-term nightly use. The material can be cleaned easily, and the included case keeps them hygienic for travel. While the upfront cost is higher than strips, the per-day value is excellent for a diligent user.
Why it’s great
- Highest airflow improvement among internal dilators
- Comfortable for side sleepers and CPAP users
- Reusable design offers strong monthly value
Good to know
- Requires a break-in period for comfort
- May fall out after several nights wear
2. Intra-Nasal Breathe Aid by Splintek (45 Day)
Designed by Splintek, this single-piece dilator features a unique semi-circle spring design that targets nostrils prone to collapsing during sleep. Unlike cone-shaped dilators that sit inside, this model uses a flexible band that sits across the septum and two gentle flares that open the nostrils from the outside—giving it a hybrid feel between an internal cone and an external strip without the adhesive.
Users praise its ability to eliminate morning headaches and cottonmouth by promoting mouth-closed breathing. Many have used it for months beyond the stated 15-day lifespan, though the material can lose tension over time. It is particularly effective for those with very narrow nostrils or a deviated septum that causes one side to collapse flat against the midline.
One caveat is that the fit can be too large for smaller nostrils, which led to some users finding it uncomfortable. However, for those with standard to larger nasal passages, it remains a top-tier choice for reducing snoring and maximizing airflow with a very low profile design.
Why it’s great
- Exceptional at preventing nostril collapse during deep sleep
- Very low external profile, barely noticeable
- Lasts significantly longer than the 15-day claim
Good to know
- May be too large for small nostrils
- Requires a precise insertion angle for comfort
3. Snore Bastion Nasal Dilators (12-Piece Set)
The Snore Bastion set is the ultimate variety pack for anyone who doesn’t know their ideal fit. It includes 12 pieces across four sizes (S, M, L, XL) and three distinct shapes, making it the most comprehensive kit for trial and error. The clear medical-grade silicone is soft, flexible, and nearly invisible once inserted, so side sleepers can move freely without the dilator being noticed.
The “smooth” style is the most universally comfortable, while the “ridged” version offers better retention for those with narrower passages. A minor drawback is that dry insertion can be uncomfortable; using a saline spray helps. Some users with very sensitive skin experienced irritation after a few nights, though this was not widespread.
Because you get multiple shapes, you can swap between them depending on your congestion level or sleeping position. The set includes a discreet carry case, making it easy to travel. For the price, this represents the best value for someone who wants to test multiple fits before committing to a single design.
Why it’s great
- Unmatched variety for finding the perfect fit
- Soft, medical-grade silicone is comfortable for long wear
- Includes small sizes ideal for narrow nostrils
Good to know
- Dry insertion can be uncomfortable
- May require lubrication every night
4. Breathe Right Clear Nasal Strips (Large)
Even in a guide focused on internal cones, the market leader in external strips deserves a spot. The Breathe Right Clear strips offer a different mechanism: they lift the sides of the nose outward, reducing nasal resistance by mechanically widening the nostrils. For many, this is the most intuitive first step before graduating to internal dilators. The clear version is nearly invisible and less sticky than the extra-strength tan version, making removal gentler for sensitive skin.
Users with oily skin report that the clear strips lose adhesion overnight, causing them to curl off. However, for those with normal to dry skin, these strips stick reliably for 8+ hours. They are excellent for daytime use during exercise or allergy season, as they require no insertion and can be applied instantly.
While they cannot match the internal lift of cones for a deviated septum, they are a fantastic non-invasive tool for mild to moderate congestion. The 30-count box offers a generous supply for daily use. If you dislike the sensation of something inside your nostril, this is your best bet.
Why it’s great
- Instant, adhesive-free application
- Excellent for daytime and exercise use
- Gentle removal formula
Good to know
- Adhesion fails on oily skin
- Less structural support than internal dilators for severe collapse
5. Sleepwell Internal Nasal Dilator (12 Count)
The Sleepwell disposable dilator is the most affordable entry point into internal cones. Its soft, flexible material is designed to simulate the nasal anatomy and is infused with lavender and chamomile essential oils, intended to promote relaxation at bedtime. The oval shape is praised for being comfortable for users with average-sized nostrils.
However, the critical drawback reported is sizing: several users found the connecting strip too short and the loops too soft to hold their shape, causing the dilator to fall out or provide marginal lift for a deviated septum. The scent, while pleasant to some, can be overwhelming, and there is no unscented option available. For a few dollars more, the Snore Bastion variety pack offers a more robust and customizable solution.
Despite these cons, some users with minor congestion or smaller nostrils have found it life-saving for reducing snoring. It is best viewed as a low-cost trial to see if the concept of an internal dilator works for you before upgrading to a reusable model. The single-use hygiene factor is also a plus for travel.
Why it’s great
- Softest material of all the disposable options
- Low entry price for first-time users
- Individual disposable capsules for hygiene
Good to know
- Strong lavender scent from essential oils
- May be too small or soft for severe septal deviation
