HOW AIRLOCK WORKS

The science behind fresh boats

AIRLOCK One uses your boat's AC system to purify the air and continuously eliminate odors, bow to stern, powered by bipolar ionization, the same technology trusted in hospital HVAC systems.

Ion Generation
1

Ion Generation

AIRLOCK One uses Bipolar Ionization to treat your boat's air. Two carbon-fiber brushes—one positively charged, one negatively charged—react with water vapor (H₂O) to create hydrogen (H⁺) and oxygen (O₂⁻) ions, which flow into your AC system.

Ion Flow
2

Ion Flow

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.

Ion Discharge
3

Ion Discharge

These 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.

Particle Neutralization
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.

Long-Lasting Effect
5

Long-Lasting Effect

Once their job is done, the ions naturally revert back into water vapor, and the cycle begins again. This self-sustaining process keeps your cabin air fresh continuously, with no filters to replace.

"BOAT SMELL" 101

Why every boat smells, and why cleaning doesn't fix it

Odors don't sit on the surface, they soak deep into materials you can't reach. So you clean, the smell fades, and within days it's back. The only real fix is to treat the air continuously. Here's what you're up against:
Boat Design Traps Air and Moisture

Boat Design Traps Air and Moisture

Boats cram plumbing, wiring, ducts, and storage behind sealed panels and under floors. In these tight, low-airflow spaces, moisture and odor-causing compounds build up fast and go unnoticed until the smell reaches the cabin.

AC system
Blower, ducts, and vents stay damp and spread odor cabin-wide
Behind-panel runs
Hidden pockets where leaks and condensation hide
Storage compartments
Enclosed spaces where moisture settles unnoticed

Mold and Mildew Growth

A boat is nearly the perfect home for mold: damp, dark, and sealed up between trips. Spores settle into soft, hidden surfaces and spread quietly, long before anything looks dirty.

Aspergillus niger
One of the most recognizable black molds in humid environments
Penicillium species
The fuzzy blue/green growth
Cladosporium species
A dark mold that shows up as dark spots

Bacteria in Standing Water

Water pooling in the bilge, drains, and holding tanks becomes a breeding ground fast. As bacteria break down the gunk, they release the smells that hang in the cabin, and the warm, salty, humid marine air only speeds it up.

Pseudomonas species
Creates that musty, fishy odor
Vibrio species
Saltwater bacteria that add to the marine funk
Sulfate-reducing bacteria
Produces that rotten egg smell from hydrogen sulfide

Off-Gassing from Boat Materials

Boats are packed with synthetic materials that release chemical fumes, or VOCs, into the cabin air. Heat and sealed-up storage make it worse, which is where that sharp "new boat" smell comes from, even on older boats.

Fiberglass resins
Release styrene compounds for months after curing
Vinyl and cushion materials
Give off plasticizers and flame retardants into the air
Adhesives and sealants
Off-gas formaldehyde and solvents, especially in heat

Great product. Hoping to get ride of the boat smell when installed.

When we bought our boat it smelled heavily of stale cigarettes. Within a month there was no more cigarette odor. Airlock has been one our best purchases for our boat. Most strongly recommended!!

So far it works great I’ll know more when I go back to boat

Was skeptical…… but my boat stank. I needed to do something. The sprays, the candles, washing the curtains, scrubbing the carpet… nothing would get rid of the mustyness, the “not so fresh” odor, and just the flat out smell of “boat.” I had a few air purifiers, I have fans blowing in every room, but these things take up space and have to be plugged into electric outlets, so I was tired of having cords running everywhere and having so many devices running that kind of sort of worked just a little bit. I bought a 1985 Chris Craft Catalina 426 about 1.5 years ago. Old boats have a stink to them. Like, this boat has been sitting in the water for over 30 years, even if the previous owners were clean freaks (they were not,) spent a lot of time cleaning and maintaining the boat (they did not), a boat this old with all sorts of carpet, fabric curtains, cloth furniture will have a unique smell that isn’t known to be pleasant. I’m a liveaboard, so the more my boat stank, the more my clothes stank, the more I just….. stank. Not like b.o. stank, I’m a clean dude and shower daily. I was clean, but my clothes had a smell of “truck stop bathroom musk” permanently imprinted on them. So, something had to be done. After researching several options, my algorithm finally caught on to what I was searching, and every other ad on instagram was for this “airlock” device. I finally clicked the link, read what they were about and mulled it over for a week or so. I was a little intimidated by the price point since I have 3 ac units on my boat (it’s a motoryacht, so from here on out we will call my boat a yacht,) so I thought it would be a pricey solution, but they advertised that there is a 90 day guarantee. I’m no sucker, and with the guarantee in place, I thought it was a good way to figure out if these things actually worked, So I bought 2 airlock units and crossed my fingers in hopes it would help. If it didn’t help, then I would gladly be sending these things back and getting my money back, because remember I’m not a sucker. I basically thought of it as a “free trial” to see if this technology worked. The big thing for me was that these units appeared to not take up valuable space on an electric outlet, wouldn’t require any cords or cables running on the floor, and the units themselves were to be placed inside the cabinet where the ac units were, and on my yacht, anything I can do to NOT take up any space is ideal. Well, the units came like 3 days after I ordered them, and I was impressed. Installed them with ease the very same day, and I was once again impressed with how straightforward and easy the install was. I literally had both units installed and running within 30 minutes of opening the box. In all honesty, I had to make a run to Lowe’s afterwards because I dropped 2 terminal screws and they fell into a space I couldn’t reach and my fat fingers couldn’t contort enough to pick em up and this is also the time that I realized that the screwdriver I was using did not have a magnetized tip….. anyway, that was user error, not the fault of airlock. Anywhoo, I was impressed with myself for how quick I got everything all connected and set up, and if you know me, I usually complicate situations, so I had a feeling of skepticism creep back in because there is no way it could have been this easy. I sat in the salon for an hour or so watching tv nervously waiting for my boat to catch on fire since I just messed with electrical stuff, but no, nothing went wrong. I went to bed, woke up the next morning to go to work and the air in the boat felt a bit crisper, and I could genuinely feel that the air just felt….. better. I’m almost done, bear with me through this final stretch…. When I got home from work the next day, the unit had been installed for less than 24 hours, and I kid you not, when I opened the door to the yacht, I actually giggled out loud, smiled super big, and maybe I did a quiet little fist pump when I immediately noticed how much those 2 airlock devices had worked. Ladies and gentleman, these devices worked. Like my boat smells practically brand new in less than 24 hours. If you know boats, the hotter it gets outside, the more that the holding tanks waft a certain smell around the cabin, the more the galley smells kind of linger in the air, and how the smell of gas/oil from the engine room just kind of always exist…… well, no more. These 2 airlock devices did more in less than 24 hours than I ever could have expected. I went from skeptical, to “what in gods name is this crazy ion technology?” to “I’m no sucker, I’ll return these things and get my money back because of that money back guarantee,” to impressed with how quick they arrived, to proud of myself for not blowing up my yacht, to smiling and overly impressed with this product. I obviously went through a range of emotions in a very short period of time. Why am I writing so much about this product you ask? Well, since my yacht smells so much better, the air feels so much cleaner, and because these airlock devices just make life all around better, I’m writing this review when I should be leaving for work, but this yacht just flat out smells so good I’m looking for any excuse to stay here on my good smelling yacht instead of leaving to go to work where the air there is NOT filtered by airlock devices. Here is the end. If you stuck with me this long, this is probably where you will find the info you are looking for… 1. Super quick delivery 2. Super easy install 3. Results were seen way sooner than expected 4. I have had these units running for about a week now, and every day seems to be better than the last, air quality wise. 5. Best thing I have done for this yacht in the 1.5 years I’ve been living on it full time was getting these devices. 6. I am absolutely going to purchase a 3rd device, and with how impressed I am, I’m going to get some of the Voyage devices for the head. I’m rarely impressed with things, I usually expect things like this to be gimmicky and not work. These work. They absolutely without a doubt have exceeded any expectations I had about these devices. 7. I kid you not, because of the improved air quality on my yacht, I’m a better person now than I was a week ago. A week ago, I was walking around just smelling like old musty boat. For the past week, I have had a smile on my face a little more often, my mood has improved, these airlock devices have not only improved my quality of life on this yacht, they have improved me as a person. 8. I will gladly tell everyone at my marina about these devices. The few people I’ve talked to in the past few days never even knew there was a hassle free option like this to improve the smells inherent on boats. I hope everyone here gets on board and starts installing these. If everyone’s mood around here improves just a little bit like mine did, maybe we wouldn’t have to yell at Danny every night because he’s blasting Lynard skinard at 11:30pm, maybe he’d feel better and learn that not everyone wants to hear “freebird” every night. Thanks for your time, and please know that these devices work, and I am one happy boater.

Seems to be working well I totally smell the difference

it has been a week and no change yet

Love our AirLocks! Amazing technology and hands down the best customer service in the industry! I have 2 installed on my 2021 27FBT Airstream Globetrotter. If you like having clean fresh smelling air in your home on wheels… AirLock is your answer!

We have a 73 foot houseboat that had been closed up for over a year before we purchased it. The interior smell was very bad. We tried everything for months, with very little improvement. Then we saw an ad for Airlock. We thought, why not? Well that was a month ago and the smell is gone, completely gone. We never dreamed it would work this well. We installed the unit on the return air side of our central air unit and it took about 3 weeks, but it cleaned the air in 750 square feet of boat. Can't praise this Airlock enough, we thought we were destined to smell this musty odor forever. Thank you Airlock!

Ordered this hoping for the best but not expecting much. I’m very happy that it working great. After being installed for a few days the odor in my boat is almost nonexistent. Easy to install and is working great. So happy with the decision to buy this for the cabin of my boat.

Extremely easy install! I installed one in our salon and one in our v-berth. I would say the boat does smell somewhat better and it does seem to help remove odors after cooking a meal quicker.

seems to make smell better, I have it on 24/76 hard wired regardless of AC on or off. Now if it ever caught fire, there is no way to know, see it or anything.. I have a 1999 290 Sundancer, and installation was extremely difficult, so be forewarned on that one.

We purchased it a little over a year ago at first it seemed to work great now it's not making a noticeable difference I'm not even sure it's working the LED is no longer lit I checked and there's power to it so I don't know maybe it just went bad I'll probably try one of the alternative products available

At first it didn't work at all, but I found out that the mount slipped and it was laying on the floor. My friend made a mount with his 3D printer which moved it closer to the fins. It worked better, but it's still not great. Honestly, I'm considering sending it back.

This is a very difficult product to review. After all the product is supposed to keep your RV or boat, in my case RV, from smelling. I think it's working, but how would I know if I don't have any smells? I can't tell you. I've had an ongoing problem with a toilet. That is the reason why I decided to put this in. I can also tell you I no longer have those smells. I think it's worth trying it because I'm familiar with a technology which is valid and you've got a 90 day warranty. Go for it!

Definitely works! No more musty odors

Already posted on IG @mv_classea tagged @airlock

Airlock has really changed the air quality in our RV. Since the install we have eliminated using the air purifier that we originally had been using. The musty smell is gone and cooking smells have been eliminated. Easy install!

I'm still not sure if it's making a big difference or not, unfortunately.

Tried just one in the v-berth of our boat. In 24 hours I can tell a difference in the room and the adjourning bathroom. Rooms smelled fresher and towels do not smell musty. We hang the towels to dry but with the moist boat environment they always seemed to have a musty smell after two or so days. No more. We installed on all additional units and there is no "odor" just the smell of clean air. Our boat is 20 plus years old, well maintained but still had some "smells". Seemed to take care of any issues. Very happy with the product.

Love the product, and the company is first-rate. I was able to easily install the Airlock One on our Hanse 385 sailboat, although I did need to splice in an extra 18 inches of wire so that the wires would reach our AC control box. So be aware that you may need to do this if your control box is a little far from the AC air intake. We also bought the Airlock Voyage for our head. Thanks for making a quality product!

As advertised-easy to install and works well. I wouldn’t say we had a major smell issue prior to installation. Our cabin has no odors since installing the Airlock. I am happy with the product.

Once I found the electrical box and figured out which terminals to connect to, it took all of 10 minutes to install and see it get right to work. I went out to dinner with some friends. It was a cool evening and needed a sweatshirt, but the one I brought smelled like musty boat so left it behind. When I came back to the boat, the cabin just smelled clean. The smell was (mostly) gone from the sweatshirt too. By the next day, all of the nasty smells were a thing of the past! Even after cooking in galley, the residual aromas don’t stick around for long. Loving this thing and so happy to have my nice clean boat smelling like a nice clean boat again!

Within 24 hours the musty, stale smell was completely gone and it smelled fresh and clean inside.

Was curious if this thing actually worked. Boy I was magically surprised. Smells going away

Not unhappy with it, believe it is helping.

I ordered it and it arrived promptly. It was easy to install and I think it works. Its only been a week so I will know better this weekend when i return to the boat

Simply Awesome! We cant believe the difference in our boat. The boat has a fresh smell.

I have noticed in my cabin I do not smell any bad moisture completely clean air so I decided to put it in my cockpit which I never smelled anything there but I’d rather use it there. Also I really believe in it is a great product. Thank you so much.

Install was pretty straightforward.

Quick easy delivery. Great boxing and packaging. Easy installation into boat. I’ve only used it a few hours so still too early to say how good it will work on the boat odors.

One word…Awesome! Easy to install and NO more mysterious smells.

Works great so far! started working immediately!

I just installed the two AirLock units yesterday, I honestly can’t tell if they are making a difference yet. I am hopeful that after a few days of continuous running they will help rid the master & VIP staterooms of that “boat” smell.

After being introduced to Airlock by Brad from Thirteen Adventures and watched his install video on his YouTube channel, I was convinced. Been using for a week now and the change in inside air quality has drastically improved. (Previously ran an air cleaner 24/7) But, Airlock has been a game changer! Thanks Brad and thanks Airlock! ⭐️⭐️⭐️⭐️⭐️

I just installed 3 Airlock One's on our 2018 Galeon 510 Sky. The installation was simple and the results are well worth the price. After the install, I ran the fans only for about an hour and could immediately tell the difference in the air quality. I can only imagine what the results will be once we splash this spring and the fans are operating 24/7 and the chiller as needed. Great product, highly recommended!

Does the job, as simple as that!

I bought 2 for my 43 year old Uniflite. I was not having an odar issue on my boat mostly because I live on my boat and I’m a firm believer in having a fan moving air all the time in every room which makes a big difference. After running the air lock for a couple hours you can smell a light faint ozone odar after a few hours that smell seem to have internalized and the air in my boat did improve slightly. I imagine it’s gonna take a few days to draw the odors out of all the soft materials on board. Next time I have a guest onboard I am planning to ask them if they smell any odors unpleasant odar a on board to see what they say. I am not sure I would notice an odar as fast because you tend to get use to certain odar and block them out. It was super easy to install took about 5 minutes it’s that easy. I honestly believe it’s a nice addition to better air quality on my boat so for health reasons it’s also good piece of mind.

Very quick shipment. Installation was a breeze. Several videos are available by the company as well as others. Took only 15 minutes from start to finish to install. Made a big difference to the smells in our Class A. We have several dogs and their smell has been eliminated, amazing. Prior to using this device we had to mask the dog smell, but now it’s gone! The air has a fresh, neutral smell now. I highly recommend this product for any AC in RV’s.

What a difference airlock makes. Pretty easy to install. Would highly recommend

I have two Airlock One units working on our boat and they work very well, boat smells fresh and new.
