No gasping. No dry throat, no pounding head, no groggy fog. Just deep, full breaths, all night. You've tried strips, tape, sprays — none of them touch the real spot inside your nose that's actually caving shut.
FLO holds it open. Starting tonight.
She's not going to ask if it worked. She's going to fall asleep before you do and stay asleep, next to you. This isn't about fixing a symptom. It's about giving her back an ordinary, quiet night. Some nights, the best thing you can give her is quiet.
One small habit. A completely different night.
"I've snored for probably ten years and my wife just accepted it. First night with FLO, she woke ME up asking if I was okay because it was so quiet. That alone was worth every penny."
"I tried every strip on the market for years. Nothing worked because apparently they're not even hitting the right spot. FLO actually targets where the real problem is. Should've known this years ago."
"Deviated septum for as long as I can remember, but never 'bad enough' to get help. This isn't a replacement for surgery, but it's the first thing that's actually given me real relief without going under the knife."
"Bought a different brand's dilator before this and it hurt by morning every time. The starter kit having all three sizes actually mattered — found mine on the first night and haven't taken it out since."
"Didn't realize how much the dry mouth and morning fog was just from mouth breathing until it stopped happening. I actually feel like a person before my coffee now."
"Was using decongestant spray every night for probably two years, knew it wasn't good for me but couldn't stop. FLO gave me an actual reason to quit. Haven't touched a bottle in three weeks."
"I run and always felt like I was fighting for air through my nose the whole time. Wear this during training now and it's a noticeably different breathing experience. Wasn't expecting that."
"That's genuinely how my family introduced me at gatherings for years. First time in a long time I don't feel like that's my whole identity. Small thing that changed more than I expected."

Yes — and this is the whole point. Strips pull on the outside of your nose. Tape controls your mouth, not your nose. Neither one reaches the internal nasal valve, which is where the actual collapse happens. FLO is built specifically for that internal point.
FLO is sized and adjusted to sit securely at the valve, not loosely inside the nostril. The Starter Kit lets you find your real fit instead of guessing with a single size.
FLO isn't a replacement for surgery if you need one — but many people with deviated septums get real, immediate relief because the internal valve (not just the septum) is often part of what's restricting airflow. It's a non-invasive option worth trying before — or alongside — anything more invasive.
Yes. FLO uses no chemicals, no adhesives, and no drugs — just gentle mechanical support. Unlike decongestant sprays, there's no dependency or rebound effect from nightly use.
That's exactly why the Starter Kit includes all three sizes. If you're still not comfortable after trying each one, you're covered by our 60-Night Comfort Guarantee.
FLO is low-profile and sits just inside the nostril — most partners notice the silence, not the device.
Rinse with warm water and mild soap after each use, let it air dry completely before storing. No special cleaning products needed.
With proper care, each piece is designed for months of regular use. If you notice any wear, cracking, or reduced flexibility, it's time to swap it out.
Yes — plenty of people wear FLO during workouts, while working, or anytime they want clearer breathing, not just at bedtime.

Overall rating: 4.9 / 5 from 50 reviews.
Honestly the most comfortable nasal product I've used, and I've tried more of these than I'd like to admit.
Feels like the missing piece after years of trying tape, sprays, and everything in between.
Sleep tracker finally shows deep sleep stages I haven't seen in years. Wasn't expecting data to back up how I felt.
I've already recommended this to three different coworkers, one of whom actually went and bought it the same day after hearing me talk about it at lunch. It's honestly hard not to bring it up once you notice how much better you're sleeping and breathing during the day too, not just at night. Once you feel the difference yourself, you kind of want everyone around you to have it too.
The internal fit makes total sense once you actually feel it working. Completely different than anything external.
Skeptical of the whole category after a bad experience with strips, but this actually delivers on what it claims.
Quiet nights, better mornings, and my girlfriend has officially stopped elbowing me awake in the middle of the night to roll over, which used to happen at least a couple times a week without fail. She actually mentioned last weekend that she can't remember the last time it happened, which I think says more than any review I could write. Everyone wins at this point, honestly.
My son has struggled with mouth breathing since he was a kid. This has genuinely helped him more than anything a specialist recommended.
Didn't think a nasal device could fix something a $3,000 dental appliance couldn't, but here we are.
Best money I've spent on a health product this year, and that's genuinely saying something considering how many wellness gadgets I've bought and abandoned over the last twelve months alone. Most of that stuff ends up in a drawer within a week once the novelty wears off. This is the one thing I've actually used every single night without fail since it arrived, which is basically unheard of for me at this point.
Comfortable, discreet, and it actually addresses the real problem instead of just masking it like the sprays did.
Really good product overall, and I can tell there was actual thought put into the design compared to a couple other brands I've tried in the past. My only real complaint is that even the small size in the starter kit felt slightly too big for my nostrils, which are on the narrower side. Ended up making it work with some minor adjusting, but a slightly smaller option would make this close to perfect for people built like me.
My fiancée booked us separate rooms on our last trip because of my snoring. Won't be necessary on the next one.
I was tired of feeling exhausted no matter how many hours I slept. Turns out it was never about the hours.
My wife hasn't slept with earplugs in months, and before this she wore them literally every single night for as long as I can remember. She actually forgot to pack them on a recent trip and didn't even realize until we got there, which tells you everything about how much things have changed. That's basically the whole review right there, everything else is just details.
Used to dread flights because of nasal congestion. Wear this now and it's made a real difference at altitude too.
Good product, effective for sure. Just took some getting used to the sensation the first couple nights.
Feels like a completely different level of sleep quality compared to what I was used to for years. I used to wake up at least once or twice a night gasping for air through my mouth without even realizing how disruptive that actually was until it stopped happening. Didn't think something this small could make that much of a difference, but here I am waking up without an alarm most mornings now because I'm actually rested.
Bought this after my husband tried three other brands that all fell out overnight. This one actually stays in place.
The sizing kit is what convinced me to buy. Didn't want to guess and be stuck with something uncomfortable.
My roommate used to complain about the noise coming through the wall on a pretty regular basis, even joked about buying me earplugs for himself instead. It got to the point where I felt genuinely embarrassed about it every time it came up. He hasn't said a single word since I started using this, and honestly I think he forgot it was ever an issue at all.
Wear it during workouts now too, not just sleep. Noticeably easier to breathe through hard sets.
Tried the cheap ones from a big box store first. Night and day difference in comfort and how well it actually stays put.
My snoring tracking app went from solid red bars every single night to green almost immediately after I started using this, which honestly caught me off guard. I'd been logging data for months trying different things with barely any improvement showing up. Wasn't expecting results this fast, figured it would take weeks of adjusting like everything else I'd tried before.
Genuinely didn't expect a nasal dilator to be this comfortable. Barely notice it by the second night.
I was the guy waking up gasping through my mouth every single night. That doesn't happen anymore.
Simple, effective, and it doesn't feel like some clunky medical device shoved up your nose the way I expected going in. My girlfriend genuinely didn't notice it for the first few nights until I finally pointed it out to her. Discreet enough that I've even worn it during an afternoon nap on the couch without anyone in the house noticing a thing.
Doctors kept telling me my septum wasn't bad enough for surgery. This is the first real relief I've had without waiting years for approval.
First night I wore it my girlfriend actually asked if something was different. Didn't even have to bring it up myself.
The comfort is honestly what sold me on trying this in the first place. I bought a rigid plastic dilator a couple years back that left actual sore spots inside my nose after just one night, so I was hesitant to try another one at all. This is nothing like that experience, the material is soft enough that I genuinely forget it's there most nights, and there's zero soreness the next morning.
Works well overall, just wish it came with a case for travel. Would've given 5 stars for that alone.
Skeptical going in since I'd wasted money on a strip that did nothing. This is a completely different category of product.
Got this for my dad who has snored my entire childhood, to the point my mom has slept in a separate room for years now. He was pretty resistant to trying yet another gadget after a few failed attempts with strips and a mouth guard he hated. He called me the next morning just to say thank you, and my mom actually texted me too which says a lot.
Woke up without a dry mouth for what feels like the first time in years. Small thing but it changes your whole morning.
Cheaper than the custom mouthguard I paid almost four thousand dollars for through my dentist, and honestly this works better without any of the jaw pain that thing gave me every single morning. I wore the mouthguard for about three months before giving up entirely because my jaw ached so much I dreaded putting it in. This has zero downside in comparison and actually helps more with the actual breathing part, not just the snoring noise.
My wife tracks my sleep on her app now just to compare notes. Numbers don't lie, this actually works.
Comfortable enough that I forget I'm wearing it by the time I fall asleep. That's the real test for me.
The mechanism actually makes a lot more sense once you understand what's going on inside your nose. I always assumed strips just didn't work well enough, but it turns out they're pulling on the outside of your nose while the actual collapse happens somewhere deeper inside near the septum. This targets that exact spot instead, which explains why it works so much better and so much faster than anything external ever did for me.
Never thought something this small could make this much of a difference. First full night of quiet sleep in longer than I want to admit.
Solid product overall. Took me a night or two of trying each size in the starter kit to get the fit exactly right, and I'll admit the first night with the wrong size wasn't great. Once I landed on medium though, it's been comfortable every night since. Only real complaint is I wish the packaging explained how to tell which size you actually need a little better instead of just trial and error.
