What the AirLock One is trying to solve
The clearest answer to what this video is about is simple: Changing Lanes wanted to find out whether the AirLock One could help reduce bad RV smells once it was installed in the path of the air conditioner. That includes the obvious test case—the infamous fart spray prank—but it also includes a more practical problem they had already been living with: a lingering musty smell in the bedroom.
That second detail matters because it keeps the video from being only a stunt. The prank spray is the attention-getter, but the underlying question is much more familiar to RV owners: can a small device in the AC system make the whole space smell cleaner, not just mask a problem for a minute or two?
The creators frame the AirLock One as a bipolar ionization device meant to work in the airflow. In the video, they describe the basic idea in plain language: mount it where air passes through, power it with AC current, and let it run so the ions can move through the rig. They are careful not to oversell that idea. Instead, they treat it as a hypothesis that has to survive actual use.
Why placement mattered more than the prank spray
Before any testing, the installation question takes center stage. The video makes a strong practical point: where the unit sits in the airflow matters. The creators say it can go in the return or supply side, but they prefer the supply side because that gives the ions a cleaner path into the living space rather than sending them through the coils first.
That detail becomes the whole reason the video is useful beyond the product itself. Many RV accessory videos stop at “here’s the thing, here’s where it went.” This one lingers on why the exact spot matters and what changes when the rig already has another system in place.
That setup is the RV Airflow system on one of their Coleman-Mach 15K AC units. Because that system alters the sealed path of the air from the supply side into the ducts, the AirLock One install is not just a normal bolt-on moment. The creators specifically said they had trouble finding a video that showed how to fit the device when RV Airflow was already installed, so they walked through their own workaround.
Installing it around RV Airflow versus a stock AC
The install itself is split into two situations.
On the AC with RV Airflow, the main challenge was physical fit. The device was magnet-mounted, but the foam around the RV Airflow assembly had to be trimmed so the AirLock One would sit flush and avoid interference. The creators describe that process as a lot of trial and error: mark the spot, cut some foam, test the fit, cut a little more, and repeat until the unit could sit cleanly in place.
Power was the other half of the job. The video notes that the AirLock One needs 120-volt AC power, and the creators had to get up on the roof, remove the AC cover, and tap into the existing wiring at the control box. They found WAGO connectors already in place and used the spare port on each one, which made the electrical side straightforward once they had access.
The stock AC in the bedroom was easier. No RV Airflow meant less trimming and less juggling of parts. The same basic wiring approach worked there too, and the device could be mounted with the supplied magnets and adhesive-backed magnet bar. The creators then added switches later, not because the AirLock One required them, but because they wanted a simple way to turn the units off and back on for testing.
That’s a helpful distinction. The switches were a test convenience, not part of the normal install. In the video, they even note that once the testing was done, the devices would just stay on as designed.
How the odor test was actually judged
The prank spray segment works because the creators did not rely on one measuring tool alone. They used Tara’s nose as the main judge and an air quality meter as a secondary reference, even though the meter did not register the spray in the way they hoped.
That outcome says something useful. The video is not pretending that an air quality meter is the same thing as a human sense of smell. Instead, it turns that mismatch into part of the story. Tara’s reaction becomes the practical standard: how bad does the air actually smell, and how quickly does that smell fade once the ACs are running?
They ran a baseline test with the AirLock One turned off, then repeated the test after the units had been running for about 90 minutes. The first round was predictably rough. Tara rated the smell high, and the bedroom still carried a musty odor afterward. The second round did not erase the prank spray instantly, but it seemed to shorten the smell’s life span. By the 45-minute check, they were calling it essentially gone.
The method was informal, but the conclusion was still meaningful: the AirLock One appeared to help the odor clear faster once it had time to run.
What the short test suggested about the musty smell
The more interesting part of the video may actually be the musty bedroom odor, not the prank spray. That smell had been lingering for a while, especially when they were in hot areas, and they had already tried spraying Microban into the vents.
After the AirLock One had been on for about 90 minutes, Tara noticed the musty smell had decreased enough that she did not really pick it up the same way she had before. That is not a full long-term verdict, and the creators do not present it as one. They are clear that many reviews they had seen suggested improvements after several days, not just a short run.
Still, the video gives a useful early signal: even a relatively short period of operation seemed to make the RV air feel less stale. For people dealing with an odd smell that keeps returning through the ductwork, that is the kind of real-world result that matters more than a polished product demo.
Why the video leaves room for longer-term follow-up
The best thing about this feature is also its biggest restraint. Changing Lanes does not try to crown the AirLock One a permanent solution from a single afternoon of testing. They call the test fun, useful, and encouraging, but they also leave the door open for future observation.
That fits the way the video is built. The creators are not just chasing a punchline with the fart spray. They are trying to understand whether an RV odor-reduction device can improve everyday living conditions inside a compact space where smells travel fast and linger longer than you want them to.
They also hint at other odor problems they want to try later, including smoke smells from neighboring campsites. That suggests the real value of the AirLock One, if it holds up, may be less about a single dramatic smell and more about how it behaves across the messy, ordinary odor situations that RV life throws at you.
For viewers trying to decide whether the product is worth attention, that is the honest takeaway: the installation was manageable, the RV Airflow fit required creativity, and the early testing pointed toward faster odor reduction rather than instant magic.
