Automotive Ozone Generators Buying Considerations


Ozone generators provide a certain number of milligrams of pure ozone air per hour, and that number can range from 3,500 mg/h to 20,000 mg/h, and sometimes even more. Most experts recommend that you use 1,000 mg/h for every 100 square feet of space you’re trying to clean. Therefore, you have to have some idea of how large your vehicle is inside before finding the right ozone generator.

In addition, it’s good to keep in mind that if your vehicle smells worse than you thought, it may take up to three sessions to make sure all of the odours and bacteria are eliminated. Indeed, the longer you’ve put up with a stinky vehicle, the longer it is likely to take to complete the job

Timer and Instructions

Every model has a different timer on the front of it with different settings, some being more tricky than others to work out. You want something that's simple to set a time for and leave without having to check on the settings constantly while it works away. Although most ozone units you'll find are straight forward in terms of setting a timer, some require a more detailed look at the instructions before use, with some even being a potential safety hazard if the instructions are not followed correctly.

It is also common that most of the instructions provided with these models are poor, so a quick check of the manufacturers page, and even a watch of a YouTube video goes a long way if it's the case.

Final Word

Ozone generators come in all sizes and strengths, and for the most part, you won’t need an exceptionally large one to clean the air inside of your vehicle. Still, it’s good to do a little due diligence on these generators so that you don't spend a lot of money just to be disappointed with the end results. To help avoid any big money spending mistakes, be sure to at least consider our 5 best ozone generators for cars picks above. Read the instructions and recommendations from the manufacturer, and most importantly, make sure all of those instructions are followed to the letter. Ozone generators are usually toxic to people and animals, so you’ll want to make sure you do everything right so that no harm comes to you or anyone else.
