Step 1

Find the right location

AIRLOCK One should be installed proximal to the AC intake airflow, to ensure that the airflow passes directly through the ion emitters.
AIRLOCK One can be installed in any direction—upright, upside down, or sideways.
The ideal mounting location is directly in front of the AC filter and coils (cooling fins). However, depending on the boat’s design and construction, this may not always be feasible. If the device cannot be centered at the base of the AC unit, use a side-mount or inverted-mount configuration, positioning it as close as possible to the AC intake airflow path.
AIRLOCK One relies on the AC unit's airflow to carry its purifying ions — if the intake is blocked or no air is being drawn in, the ions can't reach the cabin and the air won't be purified.
Make sure the ion emitters don’t touch any surface to avoid interference or damage.

Mount directly and securely in the intake airflow path

Do not mount outside the intake airflow path or leave it unsecured

Step 2

Mount the device

AIRLOCK One can be mounted in 2 different ways. Every boat is different, so we encourage you to use the one that suits your needs best.

Option A

MAGNETIC MOUNTING PLATE

Clean the surface where you want to attach the magnetic mounting plate. Ensure the surface is free from humidity, dust, grease, and oil.
Separate the magnetic mounting plate from the magnets.
Peel off the red liner to expose the adhesive and firmly press the plate onto the cleaned surface for at least 10 seconds.
Wait for 10 minutes to allow the adhesive to bond properly.
Bring the AIRLOCK One close to the mounting plate and let the magnets attract to it.

Option B

SCREWS

Firmly secure the device using the included self-drilling screws. The device can be installed either vertically or horizontally, based on your preference and needs.
When attaching the device to a grille or screen, nylon ties may be used.
The ion emitters should not touch any metal surface or wires. Move and secure any wires that may come in contact with the ion emitters.

Step 3

Locate the AC unit's wiring compartment

Identify your marine A/C unit's wiring compartment (sometimes called "electrical box", "control box," "junction box," or "terminal box"). It's typically a covered enclosure on the side or back of the unit. If you can't find it, refer to your A/C unit manual.
Remove the cover to expose the terminal block where the power wires are connected.

Step 4

Connect to power

Ensure power to the A/C unit is off at the breaker.
Locate the labels (e.g. L, N, L1, L2…) on your unit's terminal block. Check:
- The block itself
- A wiring diagram inside the electrical box
- Or your AC unit’s manual

Now connect based on what you found:

Your terminal labels	Red wire →	Black wire →
L (or L1) and N	L (or L1)	N
L1 and L2	L1	L2

To connect each wire: using a screwdriver, gently loosen the screw on that terminal, insert the wire, and tighten it back down.
Optional: if you'd rather AIRLOCK One only run while the A/C is actively running, you can connect it to the fan's power source instead.

Step 5

Turn on the power supply

Check the device is secured and correctly wired.
Turn on the power supply. A purple LED indicator will illuminate constantly when the device is working properly.
To verify output, take a non-contact voltage reader and place it near the ion emitters it should indicate voltage.
AIRLOCK One can remain powered at all times.

Reviews How it Works

FAQs

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.

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!!

JosephMarques

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.

JohnCrawford

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.

KathyHarrington

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.

CarlWestbrook

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!!

ChrisPemberton

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.

DominicCallahan

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.

MikeSteinberg

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.

MicheleBeaumont

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.

GregFontaine

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.

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

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

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

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

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

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.

Stick the Magnetic Mounting Plate near your AC unit.

Attach the device to the Magnetic Mounting Plate.

Connect to power and enjoy fresh, clean air!
