Not to mention that 1 in 5 people report adverse health effects from air fresheners. What can you do? Give up and sell the car? No way! You need to get an in-car ozone generator.

What’s Ozone and Why Is It Good at Removing Odors?

OK, before moving forward, let’s explain the basics. Ozone is a gas made up of three oxygen atoms (O3). It’s often referred to as “activated oxygen” because it has an extra oxygen atom.

While it might not sound like much, that third oxygen atom makes ozone very reactive. When ozone comes in contact with other molecules, it oxidizes them. In other words, it breaks them down into simpler molecules.

That’s why ozone is so effective at removing odors. When ozone molecules come in contact with the molecules that cause smells, it breaks them down, removing the odor in the process.

Why Use an Ozone Generator?

You might want to use an ozone generator in your car for a few reasons.

How Does an Ozone Generator Reduce Odors?

Safety Precautions of Ozone Generators
