I’ve struggled with allergies for as long as I can remember.
Spring meant constant sneezing, a blocked nose, and itchy eyes.
The cold season was even worse. What started as a simple cold often turned into a sinus infection that lasted for weeks.
Allergy pills made me sleepy. Nasal sprays helped only for a short time.
That’s when I discovered intranasal red light therapy.
In this post, I’m sharing my personal journey with intranasal red light therapy, reviewing the devices I’ve tried, and explaining the science behind why it works.
Okay, before we get into the devices, here’s the honest version.
Nasal red light therapy has the most promising evidence for allergic rhinitis symptoms such as a blocked or runny nose, sneezing, itching, and nasal irritation.
It may also help reduce swelling and make it easier to breathe through your nose.
However, it has not been proven to cure an active bacterial sinus infection, replace antibiotics, shrink nasal polyps, or prevent every cold from becoming a sinus infection.

How Does Nasal Red Light Therapy Work?
You basically clip a small red light therapy diode – usually between 630nm and 810nm – to your nose, which shines the light into your nasal cavity.
These little LED probes stimulate the blood vessels in there, which, in turn, do some pretty cool stuff:
- Improves circulation in nasal tissues
- May reduce swelling inside the nose
- Can help improve airflow through the nasal passages
- May support immune activity in the nasal lining
Which Wavelength is Scientifically Proven for Intranasal Devices?
Studies show that the most commonly used and effective wavelengths for intranasal photobiomodulation therapy (i-PBMT) are in the red (600–680 nm) and near-infrared (NIR, 800–850 nm) ranges.
These wavelengths are chosen because of their ability to penetrate biological tissues and interact with cellular components, particularly mitochondrial enzymes involved in energy metabolism.
- Red Light (600–680 nm) – Devices that use 660 nm red light have been shown to boost the activity of immune cells and help widen blood vessels by increasing nitric oxide (NO) in the body. All the devices in this list have this wavelength range.
Shining red light inside the nose is also believed to have positive effects throughout the body by affecting the blood cells in the nasal lining.
- Near-Infrared Light (800–850 nm, especially 810 nm) – Near-infrared wavelengths such as 810 nm are sometimes used because they can penetrate tissue slightly deeper than visible red light. 👉 Note: the Aswaysun device is the only one on this list with a near-infrared wavelength (850 nm)
- Blue light (450 nm) – 450 nm – blue light is mainly used to help kill or reduce harmful bacteria in the nasal passages, which can lower the risk of infections or help with sinus health. It can prevent bacterial overgrowth in the nose, making it useful for people who get frequent sinus infections. 👉 Note: The Mito Intranasal device is the only one with this wavelength.
How Long Does Nasal Red Light Therapy Take to Work?
Don’t expect one session to magically clear years of allergies.
Some people may notice easier breathing fairly quickly, while others need consistent use before they can tell whether it is helping.
In clinical studies, improvements were measured after about 2–4 weeks of regular treatment.
However, results can vary depending on the cause of your symptoms, the device, the wavelength, and how consistently you use it.
It’s also important to remember that more is not always better.
Photobiomodulation has what researchers call a “biphasic dose response.”
This means too little light may do nothing, but too much may also reduce the effect you want.
My advice? Use the device consistently for the recommended period, keep track of symptoms such as congestion, sneezing, itching, and sinus pressure, and then decide whether it is making a meaningful difference.
The 5 Best Nasal Red Light Therapy Devices
Here’s how I chose these nasal light therapy devices.
I compared each device based on:
- Wavelengths
- Treatment time
- Available output information
- Probe comfort and adjustability
- Power source and portability
- How closely it matches a clinical-study protocol
- Price, warranty, returns, and replacement parts
1. RubyLux BioNase LED Nasal Therapy Device – Best Budget
My Personal Take: If you’re curious about nasal red light therapy but don’t want to spend much, the RubyLux BioNase is the easiest starting point.
- Best for – A low-cost first trial
- Treatment time – 5 minutes twice a day
- Wavelength – 660 nm
- Evidence match: Moderate wavelength match, but no exact-device trial shown
✅ Pros – affordable, effective for clearing sinus congestion with regular use, short treatment time – 5 minutes is all you need, comes with a free replacement set of LEDs
❌ Cons – The probe spacing might be a bit wide for some noses, and some users have mentioned the auto shut-off not working. (I just disconnected the probes, and it turns off.)
Okay, let’s be real. I love a good bargain, and the Bionase is it.
For under $30, you get a super-simple device with two nasal probes that emit red light.
Plus, it even comes with extra LED lights, which is a nice bonus (though I haven’t needed to use them yet!).
Using it is ridiculously easy.
You just pop in a 9V battery (not included), turn it on, and gently insert the probes into your nostrils.
Then, you just chill for 5 minutes. There’s an auto shut-off after 15 minutes, but I find that 5 minutes, twice a day, is perfect for me.
t uses 660 nm red light, which is the same wavelength used in a small allergic rhinitis study. However, that does not prove that this exact device will produce the same results.
I would consider it mainly for allergy-related congestion and nasal irritation, not for treating an active sinus infection.
Available on Amazon ($29)
2. MitoBOOST Intranasal Device – Trusted Brand
My Personal Take: The MitoBOOST is the most expensive option here, but it is also the only one with separate red and blue light modes.
- Best for – People who specifically want separate red and blue modes
- Treatment time – 10-30 minutes (adjustable) x 4 times a week
- Wavelengths – blue (450 nm) + Red (650 nm)
✅ Pros – Dual-wavelength technology for targeted treatment, cordless and portable, easy to use (once you get the hang of it), excellent customer service
❌ Cons – It’s pricey, and the user manual could be better (but it’s not rocket science).
Yes, it’s an investment. But after using it, I can honestly say that the Mito Boost is worth it if you’re serious about getting your sinuses under control.
What I love about this device is its dual-wavelength technology.
It uses both blue light (450 nm) to zap bacteria and red light (650 nm) to reduce inflammation and boost immunity.
You can even use different wavelengths in each nostril! I usually use the blue light when I feel a cold coming on and the red light for general allergy relief.
Plus, the Mitoboost is cordless, portable, and lightweight, so I can use it while I’m working, reading, or even binge-watching my favorite shows.
The 650 nm red light is close to wavelengths studied for allergic rhinitis.
The 450 nm blue mode is interesting, but I did not find clinical evidence showing that this exact device can prevent or treat bacterial sinus infections.
I would only pay the higher price if you specifically want the dual-mode design, cordless use, longer adjustable sessions, and the brand’s warranty and customer support.
My sinuses feel clearer, I’m sleeping better, and I haven’t had a full-blown sinus infection since I started using it.
Of course, that is my personal experience. It does not prove that the device prevents sinus infections, especially since infections can vary from one season to another.
Available at MitoRedLight ($299)
3. Bionette Nasal Light Therapy – Longest Battery Life
My Personal Take: If you’re sensitive or prefer a gentler approach, the Bionette is worth considering. It’s also a good option if you’re already taking other medications, as it’s safe to use alongside them.
VIEW ON AMAZON $99
- Treatment time: 5 minutes (with auto shut-off), 2-3 times a day
- Wavelength: 630 nm, output: 4-8 mW
✅ Pros – Short treatment sessions, Adjustable nasal probes, doesn’t heat up your nostrils, long battery life (up to 80 treatments!), clinically tested
❌ Cons – Batteries are not included
The Bionette is small and simple, but don’t let its size fool you.
This little device uses a type of narrow-band red-light therapy that has been studied for allergic rhinitis.
However, I would not treat the words “clinically studied” as a guarantee that every person will get relief.
What’s cool about the Bionette is that it’s gentle yet effective.
Some users have even found relief from sinus-related headaches after years of struggling, and I know from experience how horrible those are!
Using it is a breeze: just squeeze the buttons on the sides, insert the probes, and relax. It’s so gentle, I barely even feel it.
Available on Amazon
4. Aswaysun Red Light Therapy Device – Multipurpose
My Personal Take: If you’re looking for a versatile device that can be used for multiple purposes, the Aswaysun is a great option.
VIEW ON AMAZON $50
- Best for – Red plus near-infrared light and multiple uses
- Wavelengths – 660 nm / 810 nm / 850 nm / 940 nm
- Treatment modes – 2 modes
- Treatment time – 3 minutes up to 4 times a day
✅ Pros – small and portable, designed for mouth and nose use, can also be used on small body areas, combines red and near-infrared wavelengths, useful for cold sores, canker sores, lips, face, joints, and muscles
❌ Cons – You can only treat one nostril at a time
The Aswaysun uses red light and near-infrared light, with 2 different modes to choose from.
So, you can use it for nasal treatment and certain small external areas.
It is small, portable, and easier to use on tiny areas than a larger red light therapy panel.
The only downside is that you can only use it in one nostril at a time, so it can take a little longer if you want to treat both.
Available on Amazon ($50)
5. No More Colds Red Light Therapy – Best for Comfort
VIEW ON AMAZON $40
- Best for – Soft nasal tips and USB charging
- Treatment time – 5–7 minutes, 1–2 times a day
- Wavelength – 660 nm (Red light only)
✅ Pros – Super lightweight and USB rechargeable (no batteries needed), soft, flexible nasal tips that don’t feel intrusive, has an automatic timer
❌ Cons – Doesn’t include near-infrared or blue light like some other devices
Here, the nasal probes are soft and flexible, which makes them comfortable to use.
I also love that the No More Colds Red Light Therapy is USB rechargeable – no scrambling for a 9V battery or keeping track of AAAs.
Through my research, I’ve found that some users have had significant relief from ongoing nasal irritation, while others were not so pleased, stating that the device did not meet their expectations in preventing cold symptoms.
To conclude, this is one of the more comfortable and convenient choices because the tips are soft and the battery is rechargeable.
It may be worth considering for allergy-related nasal irritation or congestion.
However, customer results appear mixed, and it should not be presented as a proven way to prevent colds or sinus infections.
Available on Amazon ($40)
What Can Intranasal Light Therapy Actually Help With?
Based on the available research, intranasal light therapy is most promising for allergic rhinitis.
Possible improvements include:
- Less nasal congestion
- Less sneezing
- Less itching
- Less runny nose
- Easier breathing through the nose
- Better allergy-related quality of life
Some people may also notice less sinus pressure if that pressure is being caused by swelling and blocked nasal airflow.
However, feeling less congested is not the same thing as curing a sinus infection.
Does Nasal Light Therapy Work for Allergies?
Several clinical studies have reported improvements in allergic rhinitis symptoms after intranasal red or red-plus-near-infrared treatment.
In one double-blind study, people used 660 nm red light for 4.4 minutes, three times a day, for 14 days. Subjective symptom improvement was reported by 72% of the allergic rhinitis group, compared with 24% of the placebo group.
Another study used a combination of 670 nm and 830 nm light for 20 minutes, twice a day, for four weeks. Participants experienced greater improvements in nasal symptoms and quality of life than the sham-treatment group.
A newer randomized trial also found improvements in nasal obstruction and rhinitis control after one month of red and infrared photobiomodulation.
These results are encouraging.
However, study protocols vary widely, and no single treatment schedule has been established as the best option for every device or every person.
Does It Work for Sinus Infections?
This is where we need to be careful.
The current research does not prove that consumer nasal red-light devices can treat an active bacterial sinus infection or prevent recurring infections.
Most of the positive studies focused on allergic rhinitis. Some even excluded people who had signs of sinusitis, polyps, or purulent discharge.
Reducing swelling in the nasal lining may help you breathe more comfortably, but that is different from eliminating a virus or bacterium inside the sinuses.
Do not delay medical care or stop prescribed antibiotics because a light device makes your nose feel temporarily clearer.
Can the Light Reach the Sinuses?
Most home devices position the probes just inside the nostrils, where the light is aimed mainly at the nasal lining.
Near-infrared light generally penetrates tissue more deeply than visible red light. However, that does not prove that enough energy reaches the deeper sinus cavities to treat an infection.
The result depends on the wavelength, output, dose, probe position, tissue thickness, and individual anatomy.
This is why I would describe these products as nasal light therapy devices, not as proven deep-sinus treatments.
How to Clean a Nasal Light Therapy Device
Anything that goes inside your nose needs to be kept clean.
After every treatment:
- Turn off and disconnect the device.
- Clean the probes exactly as directed by the manufacturer.
- Allow them to dry completely before storage.
- Store the device in a clean, dry case.
- Do not share nasal probes with another person.
- Do not soak the probes or clean them with alcohol unless the instructions specifically say that it is safe. Some materials and electrical components can be damaged by the wrong cleaning method.
If several family members use the same device, each person should have separate replaceable tips or protective covers.
Intranasal Light Therapy Side Effects
Intranasal phototherapy is generally well tolerated in clinical studies, but that does not mean side effects are impossible.
Possible problems include:
- Nasal dryness
- Temporary irritation
- Burning or discomfort
- Headache
- Nosebleeds
- Uncomfortable pressure from probes that are too wide
Stop using the device if it causes pain, bleeding, worsening irritation, or symptoms that continue after treatment.
FAQ
Can Nasal Red Light Therapy Shrink Nasal Polyps?
This has not been shown for the consumer red and near-infrared devices reviewed here. A small 660 nm study found no improvement among participants with polyps.
Is Blue Light Better for Recurring Sinus Infections?
Blue light can have antimicrobial effects under certain laboratory conditions.
However, there is not enough human evidence to say that a 450 nm home nasal device prevents or treats recurring sinus infections.
Can I Use a Nasal Light Device with a Steroid Spray?
Do not stop a prescribed steroid spray. Because devices and medications differ, check the manufacturer’s instructions and ask your doctor or pharmacist how to combine them safely.
Conclusion
If you struggle with constant nasal congestion, allergies, or sinus irritation, intranasal red light therapy may be worth trying.
These small devices take only a few minutes per day and can provide relief without relying entirely on medication.
If you’re curious, start with one of the devices above and see how your body responds.
Don’t forget, you can also use an infrared heat lamp for allergy relief!
To your health and happiness,

I have severe swelling on the bridge of my nose..from my sinuses. I tried everything to get the swelling down, and nothing seems to work. Do you think red light theropy would help get the swelling down?
Yes, I think you could benefit from an intranasal red light therapy device – see the post to find out more.
What are the effects on the heart? I have HyperPOTS where I have increased blood pressure and BPM, the vasodilation scares me as that’s already an issue for me, looking for better blood flow with some vasoconstriction, but any vasodilation will make it worse. The ideal scenario is lower blood pressure with vasoconstriction. Also have Arrythmia on occasion, any research on these products with reducing arrhythmia?
According to what I’ve found, red light therapy (through LEDs) does not have any negative effects on the heart. And, normally, illumination does not have an effect on the heart’s electrical activity. In fact, some scientists are now convinced that light pulses can be used to replace electric shocks for normalizing heartbeat.
To be on the safe side, consult with your doctor before you start any treatment with light therapy.
Can it increase polyps? Reason I am asking… since one of the reasons light therapy works is stimulations of mitochondria and feeding cells. I read an article about the continued debate regarding cancer about whether it improves or makes it worse due to simulation of that cell feeding process.
I was wondering if then polyps could be made worse due to similar.
That’s a great question. From my knowledge about red and infrared light therapy, these wavelengths, which you are naturally exposed to when you go out to the sun, do feed the cell as you said, and thus make it healthier. Any batch of cells that are not healthy and not supposed to be there (such as tumors or polyps) – become healthier and thus stops growing abnormally or growing at all. That’s why when you expose a tumor to heat (infrared light) – the tumor is damaged but the surrounding, healthy cells are not affected. I hope this helps.
Do you think these devices work for non allergic rhinitis?
Yes, they can work. They do not target the allergy triggers but manage the symptoms of rhinitis – naturally and with no medication. It’s worth a try…
Is it safe to use this device if you get nosebleeds?
I can’t find a science-backed answer for you, unfortunately,but I don’t see why not.
I was looking for the best lamp to buy and what wattage worked best, so was disappointed with your info😞
You simply came to the wrong page Gilian…:) here’s my post about lamps: https://www.infrared-light-therapy.com/infrared-heat-lamp-therapy/
I hope it helps.
Hi – I suffer from an iatrogenic condition called Empty Nose Syndrome. In short, I had a turbinate reduction surgery with approximately 20% excised leaving me with one of many side effects, including rhinitis sicca, otherwise known as a dry mucosa. I’ve been investigating these devices for a few months now and ran across this article. If LLLT (redlight therapy) does what it says for mucosal tissues, such as increasing blood flow, enhancing blood oxygen saturation, repairing blood capillaries, improved nasal anti-virus/germs ability, and strengthening detoxification ability of the nasal mucosa, I would think that these improvements should offer a stable environment for improving moisture to the epithelial layer of the nasal mucosa as found on the turbinates. I welcome your thoughts – thank you.
I think you are absolutely right David, I would definitely try it!
Omg Same thing happened to me the stupid doctor did that to me and my nose is always dry now
I bought the hailcare and its really helped me. Combined with saline nasal spray every evening, I have stopped my telfast pills and avymist spray :-) Thank you to this page for sharing this info.
I’m thrilled to hear about your results. Thanks for sharing with us! 😍
I am interested in photobiomudulation for whole body healing. Does the products you sell or tell us about do this? Could one use different color led light diodes for different therapy, like perhaps target different places in the body that may need to be activated if they are not working the way they should? Are these different colored led light diodes available? Could you tell me of where I could read more research? Thanks, Angel33
Yes, different colors treat different conditions and you can use them on various body parts. Different colored LEDs do exist, but mostly not in one device – except for facial masks and one more type of device. If you’ll tell me exactly what you want to treat I can help you find the right device for you.
I have nasal congestion that I cant get rid of for about 7 years.
I am going to buy one of these.
Hope it works.
I think that’s a good idea. I’d love it if you come back to share your results with us 😍
Hi, what’s your feedback about Bionette ? Thanks for sharing.
