90-DAY
PERFORMANCE GUARANTEE
Your boat should smell like nothing at all.
One 15-minute install inside the marine AC unit you already run.
Boat smell is not a surface problem. It is in the air below deck, and it comes back every time you close the hatch on a damp cabin.
That is why the locker fills up with sprays, gels and moisture bags you keep rebuying, and why the cabin smells fine for a day after you clean and then smells like a boat again.
AIRLOCK One treats the air itself, continuously, through the marine AC unit that is already moving it.
Treat the air, not the surfaces.
Do that and the smell has nowhere left to sit.
Here is the truth about boat smell
It is not “just how boats smell.”
Many boat owners end up here:
✗
The cabin smells fine for a day after you clean, then it is back
✗
A locker full of sprays, gels and moisture bags you keep rebuying
✗
Guests notice it the moment they step below, and you stop noticing
It is worst after the boat has sat closed up for weeks or months
The products were never built for this.
Every spray, gel and absorber you bought was built to cover an odor or pull a little moisture out of a locker. None of them was built to treat the air, and none of them keeps working once you lock up and drive home.
Your air is what carries it.
Fix the air, and the smell stops coming back.
Why everything you have tried made sense, and still did not work
You did not fail. The strategy failed you.
New hoses, clean coils, a scrubbed bilge. Every one of those jobs was worth doing, and every one of them went after a surface.
The cause is the air.
And the reason is simple:
Your boat was built to hold air in, not to keep it fresh.
Boats cram plumbing, wiring, ducts and storage behind sealed panels and under floors. Superyachts optimize for looks and space efficiency; the tradeoff is the air inside, where odor-causing compounds can build up out of sight.
In those tight, low-airflow spaces, moisture and odor-causing compounds build up fast and go unnoticed until the smell reaches the cabin.
Then the boat sits closed up between weekends, and the same air circulates through the same soft surfaces for days.
Nothing you wipe down reaches it, because it has soaked deep into materials a sponge never gets to.
And the harder you work on the surfaces without treating the air first, the more the same pattern repeats:
Sprays and air fresheners
And the harder you work on the surfaces without treating the air first, the more the same pattern repeats:
Gels and odor absorbers
They pull a little moisture out of the locker they sit in. They do nothing for the air moving through the rest of the boat, and they quit the moment they dry out.
Scrubbing and new hoses
Worth doing, and they fix what they touch. But odor molecules live in the air and in the soft surfaces a sponge never reaches, so the smell comes back as soon as the boat closes up.
Ozone machines
Nobody can be aboard while it runs. Ozone can degrade cushions and soft surfaces, and it is unsafe to breathe. The smell returns as soon as the air does.
The owners who finally stop fighting boat smell, the ones who quit rebuying consumables every season, are the ones who treat the air the boat actually holds.
Treat the air. Keep it treated.
That is exactly what AIRLOCK One is built to do.
And what about the other options?
Say no to cover-ups and clear-the-boat fixes.
Sprays, gels and absorbers:
✗
They put a second smell on the first, so the cabin carries both
✗
They only work while you keep rebuying them, then it is back
✗
They quit the moment you lock up, which is when the smell settles in
Ozone machines:
✗
Everyone has to clear off the boat while one runs
✗
They work in short bursts, not continuously, so the air is untreated in between
✗
The ozone can degrade cushions and soft surfaces over time
You should not have to choose between a cabin that smells like chemicals and a cabin nobody can sit in. AIRLOCK One is not an ozone generator, and it is safe to run while you are aboard, around pets and kids.

Bottom line: sprays and gels cover the air for a while and ozone machines make you leave the boat. AIRLOCK One treats the air through the marine AC unit you already run, with nothing to rebuy.
Put boat smell to rest for good.
Do I need to run my AC all the time?
No — AIRLOCK One works whenever your AC fan is moving air (it doesn't need to be cooling).
The longer it runs, the better the air purification — but hundreds of customers get great results running the AC a few hours at a time, whenever they're aboard.
Boat unplugged for the season? Expect a few days of runtime at launch to clear storage smells.
Not sure it'll work for your setup? Try it for 90 days, risk-free.
Is AIRLOCK One ozone-safe?
Yes — AIRLOCK One is not an ozone generator.
It's certified to UL 867 and operates well below the 0.05 ppm ozone limit used by UL and recognized in FDA regulations — a level comparable to what a laser printer produces.
Clean air, no ozone, and safe for people, pets, and the materials in your boat.
Don't have AC onboard?
AIRLOCK One works through your boat's AC system. No AC? AIRLOCK Voyage was built for you — plug-and-play, no installation, made for tight spaces like bathrooms, galleys, and bunks.
It won't cover the whole cabin, but it backs you up exactly where air doesn't move.
How easy is the installation?
Most boaters finish in under 15 minutes. Basic tools, clear steps — and if you want a hand, there are dozens of install videos ready for you.

I just installed this last weekend and by the end of our stay we noticed a huge difference in the air quality. Literally took all of 10 minutes to install. I will be getting another one for the forward cabin. Great technology which is used on large scale systems in Biopharma and hospitals. Perfect for boats!!
When I first got it, I was kind of skeptical because I really couldn't tell a difference and I was like this is one of those Facebook scam items but then about after a week I definitely could start telling a difference. Then after two weeks everything changed, all boat smells were gone.
I had a muskrat make it’s home my boat. The smell was nasty. It took about a week. But the smell is gone. This works.
I like everyone was skeptical but decided to give this Airlock a try… Almost immediately after installing it was gone. Now just nice clean fresh air. Who knew this existed.
I put two, 1 for each AC, on my 36 1988 Tiara and I have to say there is no odor of any sort which is great!!
So have had them going for almost 3 weeks now. Have an 04 39 Silverton. AC’s running on the weekend and then in humidity mode when I’m gone. It’s 90% better already. Even had someone mention it smelled like a new boat and we don’t have any air fresheners.
Installed mine and I am loving it. It definitely made a difference in about 48 hrs. Now it’s been running for over a week. My wife and I came to the boat this weekend and were thrilled with the results so far.
I just installed one a couple weeks ago it is amazing how well it works. I have it mounted directly in front of my AC unit and all I smell is fresh air.
This worked within 24 hours...only bought one and put on salon air unit. We don’t use the AFT much. 89 3207 Carver Yachting. Great purchase so far.
Boat always had a lingering mildew smell no matter how much we cleaned and used every option: nosguard, deep cleaning, air purifiers. Put this in and did not think it would work. After two days onboard… there was no smell at all. No smell, no cover up fragrance, no weird ozone smell, nothing.

What boat owners are actually saying
★★★★★
4.8 stars across verified reviews
The science behind fresh boats
What actually happens in the air.
AIRLOCK One uses hospital-grade ionization to neutralize mold spores and the VOCs behind the smell at the molecular level, using your boat’s AC to move treated air through the cabin.
1
Ion generation
Two carbon-fiber brushes, one positively charged and one negatively charged, react with water vapor to create hydrogen and oxygen ions, which flow into your AC system.
2
Ion generation
Once released, the ions travel through your boat’s ductwork via the AC system. As air circulates they reach every surface, from cushions to wall panels to the hard-to-reach spots where odors tend to linger.
3
Ion discharge
Those charged ions actively seek out airborne pollutants like odor-causing molecules, mold spores, allergens, bacteria and dust. They attach to the particles and break them down at the molecular level, right where they float in your cabin air.
4
Particle neutralization
As the ions do their work the neutralized particles clump together and grow heavier. No longer able to stay airborne, they fall out of the air and are captured by your AC filter, cleared from the cabin for good.
5
Long-lasting effect
Once their job is done the ions revert back into water vapor and the cycle begins again. That self-sustaining process keeps your cabin air fresh continuously, with no filters to replace.
It is UL 867 Certified, CARB Registered, and not an ozone generator, so it is safe to run while you are aboard, around pets and kids.
What to expect.
In the first 24 hours
The musty, closed‑up smell starts fading.
Run your AC as usual. Most owners notice the difference in under 24 hours, without adding a single scent to the air.

Within 24 hours the musty, stale smell was completely gone and it smelled fresh and clean inside.
Over the season
The boat stops smelling like a boat, and stays that way.
Because the air is treated continuously, the smell does not creep back between trips, even after closed-up weeks at the dock.
