Your RV should smell like nothing at all.
Not last night's dinner, not the dog, not the bathroom. One 15-minute install inside the rooftop AC you already run.
90-Day Risk-Free Trial
"What it does is make it not smell at all."
An RV is a clever piece of design: a whole house built to fit on wheels. That smart design has one side effect, and it's the reason the coach smells fine for a day after you clean, then smells like the RV again.
"JUST bought a new travel trailer and wanted to install these before it was ever slept in, cooked in, bathroom used, etc."
It isn't the surfaces. It's the air, and something in your rig already moves that air every day. More on that below.
Treat the air, not the surfaces.
"We used to have odors from several sources in the camper. They don't mask the smells, they remove them."
The truth about RV smell
It isn't "just how RVs smell." It's how RVs are built.
An RV fits a kitchen, a bathroom, a bed and usually a dog into a few hundred square feet. It's built around layout and weight, so every smell shares the same air and has nowhere to go but into the cushions. Dinner, the dog and the bathroom stack up in that air, hang around, and soak into the mattress and curtains.
"Before AIRLOCK, the RV would hold on to cooking smells for hours and campfire smoke lingered overnight."
A lot of RV owners end up here:
- The coach smells fine for a day after you clean, then it's back
- A cabinet full of sprays, plug-ins and candles you keep rebuying
- The bathroom smell drifts into the bedroom on hot days
- The first trip after storage, you open the door to musty air (that one gets its own section further down)
So why does every fix wear off by the next morning?
Why nothing you’ve tried has stuck
You didn't fail. The strategy failed you.
Wiping down, washing cushions and tank treatment were all worth doing, and each one went after a surface or a source. The smell was in the shared air the whole time.
About the black tank: a bad toilet seal, a dry P-trap or a stuck roof vent is a plumbing fix, and no air treatment replaces it. Fix the seal or vent first, then AIRLOCK One clears what's already in the air.
- Sprays, plug-ins and candles lay a scent over the smell. In a rig this size it fades by morning, and the smell is still in the cushions.
- A roof fan helps while it's open and running. The smell that soaked into the cushions is still there when you close up.
- Tank treatments and enzymes treat the tank, not the air that already got out.
- Ozone machines mean everyone, the dog included, clears out while one runs. AIRLOCK One is not an ozone generator.
- Stand-alone purifiers take counter space and an outlet a rig can't spare.
You shouldn't have to choose between a rig that smells like chemicals and a rig nobody can sit in. The fix has to treat the shared air itself, every time it moves, and what already moves it around your rig every day is the rooftop AC. AIRLOCK One installs inside it.
How does something tucked inside the AC reach the couch, the kitchen and the dog bed? Hold that thought. First, what RV owners say they smell now.
What RV owners notice now
"You might be disappointed if you think this is gonna make your RV smell like a rose garden. It doesn't. What it does is make it not smell at all."
"We've had our airlock in our 24 ft RV for a few weeks. It has definitely helped with the stale air smell due to being stored in the summer heat."
"The musty smell is gone and cooking smells have been eliminated. Easy install!"
"Really takes away the odors from cooking, and the humidity smell that campers can often get."
"That's great to remove dog odor smell in small spaces like a RV"
Dogs, wet towels and dinner. AIRLOCK One adds no scent on top of them. Owners describe an absence when they walk in and in the hours after.
"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."
Next question: will it fit the AC on your roof?
Fits the rooftop AC you already have
- Ducted or non-ducted. It works with both.
- One per AC. A ducted system with several ceiling vents counts as one. Count units, not vents.
- 15-minute install from inside. Drop the ceiling grille, mount it, connect two wires.
- Runs on the AC's own power. It uses the rooftop AC's 100 to 240V supply (not 12V or 48V DC) and treats the air whenever the fan runs, cooling or not. When the rig's power is off, it's off.
"Took only 15 minutes from start to finish to install."
So why put it in the AC instead of one more thing on the counter?
Fresh air at the source, not another cover-up.
Nothing to rebuy, and no outlet or cord, because it runs off the AC's own power.

How AIRLOCK One compares
| AIRLOCK One | Sprays & plug-ins | Stand-alone purifier | Ozone machine | |
|---|---|---|---|---|
| Treats the air the AC moves | ✓ | ✕ | ✕ | ✕ |
| Safe while you're inside, with pets | ✓ | ✓ | ✓ | ✕ |
| No counter space or outlet | ✓ | ✕ | ✕ | ✕ |
| Nothing to refill or replace | ✓ | ✕ | ✕ | ✕ |
Bottom line: ozone machines make you and the dog leave the rig, and sprays only cover the air for a while.
That's a rig you're using. What about one that sat in storage all season?
The first trip out after storage
A shut rig holds the humidity that was inside the day it was parked, and the soft goods soak it up.
AIRLOCK One runs on the rooftop AC's power, so while the rig sat unplugged, it was off and did nothing. It picks up when you plug in and the fan runs again, and clears the stored smell over your first trips out.
"We had a musty odor in our Airstream after it was stored for a few weeks. … The air quality is fantastic and no trace of any musty odor or food smells remains."
So on a normal trip, how fast should you expect to notice it?
What to expect
In the first week, the musty, closed-up smell starts fading.
Run the AC fan as usual. Most owners notice it during the first week.
Tank or bathroom smell takes a few days once the source is fixed.
"Works great in about 3 days the tank odors were gone."
After storage, plan on weeks of fan time.
The air clears first, and the soft goods catch up after.

How it works, in 3 steps
Back to the question from earlier: how does something tucked inside the AC reach the couch, the kitchen and the dog bed?
AIRLOCK One makes ions inside the rooftop AC.
The AC fan carries them through the rig.
They break down odor molecules in the air instead of covering them, and the particles clump together and drop out of the air.

RV creators who tested it on their own rigs
"We used to rely on diffusers, plugins, and chemicals. Then we stopped all of them to test AIRLOCK."
"It's not what you smell when you walk in, it's what you don't smell."
"…there's no smell at all. It's just air."
"We cook with a lot of garlic and even make dog food in the RV. … Since installing AIRLOCK, there's zero odor when we walk in."

Questions RV owners ask
Does it need power?
Yes. It runs on the rooftop AC's own power whenever the AC fan runs, with no outlet, battery or cord. When the rig's power is off, it's off.
Ducted or non-ducted?
Both, one per rooftop AC.
Will it work on a 12V rooftop AC?
Not yet. It needs a 100 to 240V AC unit.
Will it fix my black tank smell?
Fix a bad seal, dry P-trap or stuck vent first. Then it clears what's already in the air.
