1. AIRMAX Nasal Dilators Sport
Best for: Athletes needing a reusable, long-term nasal breathing aid.
These nasal dilators work by physically widening the nasal cavities to allow for more effective airflow than standard adhesive strips. Because they’re reusable for up to two months, they offer a durable solution that you can clean easily with warm water and store in the included hygienic container.
The set includes both small and medium sizes, which helps you find the most comfortable fit for your specific nose shape. This product isn’t for those who prefer single-use adhesive strips, as the physical presence of the dilator inside the nostril may require a brief adjustment period for some users.
Pros:

This device is a drug-free option that fits internally to support the nasal passages without medication. You should choose this if you need a natural solution for performance gains. However, avoid this if you feel uncomfortable with internal devices, as the stent must remain inside the nose for the duration of your activity.
If you’re unsure of your fit, start with the medium size to test the tension. Proper sizing is the only way to ensure the stent remains stable during movement.
Pros:
- Increases airflow by 38%.
- Made of medical-grade polymers.
- Available in three sizes.
- Drug-free relief solution.
Cons:
- Internal fit may distract.
- Requires specific size choice.
3. Breathe Right Sport Nasal Strips
Best for: Athletes who prefer an external, sweat-resistant strip.
Breathe Right Sport strips feature a flexible spring-like band that lifts the sides of the nose to open passages from the outside. The ActiveVent design includes specific vents in the wings that allow sweat to escape, ensuring the adhesive maintains a strong hold during running, cycling, and other movement-heavy sports.
In a study of people with nasal congestion, 97% reported breathing more easily during their workout while wearing these strips. This is a drug-free way to manage congestion without chemicals or sprays entering your body. It works instantly and continues to function as long as you wear it.
You should choose these if you need external support that stays on through perspiration. However, if you require internal mechanical dilators for severe structural issues, these strips may not provide enough lift.
Pros:
- Designed for sweat resistance.
- Simple external application.
- No internal components.
Cons:
- Single-use only.
- Adhesive may irritate skin.
4. FODJO Athletic Nasal Strips
Best for: High-performance athletes needing reliable, long-lasting adhesion.
These strips are engineered with a heavy-duty, sweat-resistant adhesive that’s meant to stay in place during the most strenuous training sessions. By mechanically lifting the sides of the nose, they aim to maximize oxygen intake, which can be useful for those managing deviated septums or congestion while weightlifting or cycling.
The lightweight, flexible material conforms to the shape of the nose to provide consistent expansion. This product isn’t for those looking for a permanent device, as these are designed for one-time use and must be removed after your training session is complete.
Pros:
- Heavy-duty adhesive strength.
- Expands passages up to 30%.
- Comfortable, lightweight material.
Cons:
- Must be discarded after use.
- No reusable parts included.
5. Intake Breathing Nasal Strip Starter Kit
Best for: Users who want a secure, magnetic-based mechanical dilator.
The Intake system uses a unique two-part design with independent nasal tabs and a magnetic relief band to pull the nasal passages outward. This approach avoids relying on the bridge of the nose for support, which can provide a more comfortable experience for those who find standard strips too restrictive.
It’s a patented, drug-free solution that’s built to keep nasal passages at their widest capacity for better airflow. This device isn’t for people who prefer a simple, “stick-and-go” strip, as the magnetic setup requires applying the tabs to your nose before attaching the relief band.
Pros:
- Patented magnetic technology.
- Comfortable external band design.
- Effective for deviated septums.
Cons:
- The application process is split into two separate steps.
- Requires magnetic band adjustment.

Best for: Athletes looking to build core respiratory muscle strength.
This device uses an adjustable resistance knob to help you train your lungs and diaphragm. It is a compact, 4-inch tool that you can easily carry in your gym bag for daily training sessions of 10 to 15 reps.
The food-grade silicone mouthpiece is built to last and is simple to clean with water. This exerciser isn’t for individuals expecting instant nasal relief, as its primary purpose is long-term respiratory muscle conditioning rather than immediate mechanical nasal dilation.
To see results, you must commit to 2 to 4 sets daily. Beginners should start with light resistance, while advanced users can scale up the knob to reach challenging levels.
Pros:
- Fully adjustable resistance levels.
- Compact and portable design.
- Durable, rust-free silicone mouthpiece.
Cons:
- No immediate nasal opening.
- Requires consistent daily training to achieve results.
7. Lixada Advanced Breathing Trainer
Best for: Swimmers and runners needing independent inhalation and exhalation training.
The Lixada trainer stands out by offering eight distinct resistance levels that you can adjust separately for breathing in and out. This level of customization is designed to help athletes strengthen their respiratory muscles more precisely than with single-knob devices.
The kit comes complete with a storage box and a nose clip, making it a comprehensive package for focused training sessions. This device isn’t for beginners who might find the dual-adjustment system overly complex, as it requires some experimentation to find the right balance for your specific endurance goals.
If you’re a novice, start at the lowest resistance setting for both inhalation and exhalation. Only increase the difficulty once you can complete your full training session without feeling lightheaded or straining your neck muscles. Failing to calibrate these levels properly often leads to poor form, which negates the intended benefits for your vital capacity.
Pros:
- Eight levels of resistance.
- Independent inhalation/exhalation adjustment.
- Includes nose clip.
Cons:
- May be complex for beginners.
- Requires manual level adjustments.
8. HumanN Neo40 Daily Heart & Blood Circulation Supplements to Boost
Best for: Users over 40 seeking systemic nitric oxide support.

These quick-dissolve tablets are designed to be taken on the go, providing a convenient way to support blood circulation and heart health without needing to mix powders.
The tablets have a fruity flavor to avoid the aftertaste often associated with other supplements. This product isn’t for those who prefer natural food sources or drink mixes, as these tablets are a specific, concentrated supplement meant for a daily routine.
Pros:
- Convenient quick-dissolve tablets.
- Supports nitric oxide production.
- No L-Arginine required.
Cons:
- Specific to age 40+.
- Limited to tablet format.

It’s formulated to boost nitric oxide levels and support healthy blood pressure, making it a comprehensive choice for those who want to combine heart health with their exercise routine.
The formula is free from caffeine and stimulants, relying instead on high-quality plant extracts. This product isn’t for anyone who dislikes the taste of lime or prefers a pill-based supplement, as it requires mixing the powder into 6 to 8 ounces of liquid before consumption.
Pros:
- The formula contains a comprehensive blend of active ingredients.
- Zero caffeine or stimulants.
- Easy to dissolve formula.
Cons:
- Requires mixing with liquid.
- Not a pill supplement.
10. Sparthos High Altitude Training Mask
Best for: Athletes simulating altitude to toughen the diaphragm.
The Sparthos mask features 16 different breathing levels that you can switch between without removing the mask during your workout. By simulating high altitude, it forces your respiratory system to work harder. This process helps increase your endurance and fatigue resistance.
The mask is anatomically designed to fit securely during running, cycling, or aerobic exercises. However, you must choose your intensity carefully. If you’re new to high-intensity training, start at the lowest setting.
Pros:
- 16 adjustable breathing levels.
- Simulates high altitude training.
- Secure anatomical fit.
Cons:
- Very high resistance levels.
- Not for beginners.
Always prioritize consistent, deep breaths over maximum resistance settings.
How to Choose Nasal Breathing for Exercise to Boost Nitric Oxide
Which type of breathing aid is right for me?
If you suffer from nasal congestion that prevents you from breathing through your nose during exercise, a mechanical dilator or strip is your best choice. Internal dilators like AIRMAX Nasal Dilators Sport or external strips like Breathe Right Sport work instantly to open passages. If you’re already breathing well but want to improve your stamina or lung capacity, a resistance trainer like the Expand-A-Lung Breathing Exerciser is better. If your goal is to support your blood pressure or general cardiovascular health, a supplement like DOBEL Nitric Oxide Powder is the more effective route.
Do I need to worry about the materials in these products?
Most modern nasal dilators are made from medical-grade polymers or silicone, which are chosen for their safety and durability. If you have sensitive skin, always check if the adhesive in a nasal strip is labeled as skin-safe or sweat-resistant. For supplements, verify the ingredient list to ensure they’re free from additives or stimulants if you’re sensitive to them. According to the U.S. Food and Drug Administration, it’s essential to review the labels of any dietary supplement to understand the ingredients and intended use before starting a new regimen.
Can these products actually lower my blood pressure?
While some supplements like DOBEL Nitric Oxide Powder contain ingredients that support healthy blood pressure, they aren’t a substitute for medical treatment. Nitric oxide helps with blood vessel dilation, which can support circulation, but these products are generally classified as dietary supplements. Always talk to a healthcare professional before using supplements to manage health conditions. If you’re using dilators, remember that their primary function is to improve nasal airflow, which encourages nasal breathing rather than mouth breathing, a change that can have its own benefits for your overall respiratory comfort.
Frequently Asked Questions
What should I do if my nasal strip keeps falling off?
If your nasal strip isn’t staying in place, ensure your face is completely clean and dry before application. Oils, sweat, or lotions prevent the adhesive from bonding correctly. For more intense activity, consider a product like FODJO Athletic Nasal Strips, which features heavy-duty, sweat-resistant adhesive.
Is the Expand-A-Lung trainer enough for my lung capacity?
The Expand-A-Lung Breathing Exerciser builds respiratory muscle strength through adjustable resistance. By using it for daily sets of repetitions, you can condition your diaphragm and core performance muscles. If you need more specialized training, the Lixada Advanced Breathing Trainer allows for independent inhalation and exhalation adjustment.
What goes wrong first with these breathing devices?
Mechanical nasal dilators eventually experience material wear or loss of shape. While products like AIRMAX Nasal Dilators Sport are reusable, they should be cleaned and inspected regularly for damage. For nasal strips, the adhesive is the component that typically fails first when exposed to excessive moisture or skin oils.
Are these products safe to use with other medical aids?
Many products, including the Intake Breathing Starter Kit, are drug-free and can be used alongside aids like nasal sprays. Always check manufacturer instructions for warnings regarding your health routine. If you have a deviated septum or structural nasal issues, consult a doctor to ensure a mechanical dilator is appropriate.
Closing
Selecting the right tool depends on whether you need immediate mechanical assistance or long-term cardiovascular support. For physical airflow, the AIRMAX Nasal Dilators Sport is a specialist-backed, reusable choice, while the Rhinomed Turbine Sport offers a clinically tested, drug-free stent. If you prefer external strips, Breathe Right Sport and FODJO provide sweat-resistant options, whereas the Intake system uses a unique magnetic band for those seeking a more durable, long-term fit.
If your goal is systemic improvement, the DOBEL Nitric Oxide Powder provides a concentrated, multi-faceted beetroot formula to support circulation. For those looking to condition respiratory muscles, devices like the Expand-A-Lung or Lixada trainer offer adjustable resistance to build core airflow strength over 2-4 weeks. Before starting any new supplement or training routine, evaluate your specific goals. Test one product at a time to isolate how your body responds to the change in airflow or circulation before adding further complexity.
