Here at VISOR, we don’t normally feature gadgets that claim to improve the air quality within a vehicle’s cabin. There’s just too much of those out on the market, and all of them supposedly rid your car’s cabin of airborne contaminants. However, there is one device that we simply couldn’t pass up trying out for ourselves for a very good reason.

It’s called Dr. Clo, a “Class 1 Hospital Grade disinfectant product,” according to its creator. It contains a mixture of chemicals that form chlorine dioxide that apparently kills bacteria and viruses by smashing through their outer membranes. The maker claims that the Dr. Clo sanitizing stick is 99.9% effective, much like the advertised potency of most store-bought bath soaps.

The nice thing about Dr. Clo is that it is extremely easy to use. It’s basically a stick that’s not much longer than a disposable ballpoint pen. Just like activating a glow stick, simply bend Dr. Clo until the canister inside breaks in order to start the release of chlorine dioxide. One stick is said to be good for up to 60 days, with a handy indicator on the side to let you know if it needs replacing.

As you can see in the pictures, we’ve fitted Dr. Clo to our test vehicle without any equipment or knowledge to determine if it actually works. But the one thing that caught our attention is this device’s US Food and Drug Administration certificate, which was confirmed by a quick search of the device’s registration. If it’s good enough for the FDA, it’s probably good enough for our ride.

Aside from it not requiring any power source to function, Dr. Clo can be utilized for purposes other than cars. A quick look at the website shows that the product has different variations, such as for refrigerator and bathroom use. And the P599 purchase price for the automobile version is quite reasonable for something that’s certified by a legitimate authority.
