Buying Guide

How to Pick The Best Ozone Generator For Mold?

Ozone generators can help reduce a wide range of health hazards, like mold and bacteria. But how do you choose between all the available options? We’ve put together a list of factors to consider when buying your ozone generator.


Capacity is a key factor to keep in mind when shopping for an ozone generator. Each generator’s capacity is typically measured in milligrams per hour. That indicates how quickly the unit can produce ozone. A high capacity means it can make more ozone in less time.

However, you shouldn’t make purchases based purely on performance. Some industrial-grade generators have a very high capacity and are unsuitable for residential units.

Coverage area

The generator’s coverage must be at least equal to the size of your living area. If it isn’t, then bacteria and mold will grow in places that it can’t reach. The same goes for small spaces. If you are using it in a garage, don’t get an industrial-sized machine for bigger areas (or warehouses).

Timer availability

Ozone generators that come with a timer are extra convenient. With a timer, you can set the generator to release ozone when you want, giving you time to leave the area before it goes off.

Is an Ozone Generator Alone Enough to Kill Mold?

Sadly, an ozone generator doesn’t solve everything. While it’s true that they’ll help you deal with mold, this machine alone isn’t enough.

Mold thrives in humid conditions and spreads quickly. So, there’s no way of knowing how long it will take to get rid of mold spores in your home. Unfortunately, once the mold is in homes, the spores may continue to spread even when you can no longer see them. The only real solution for mold is to identify the source and eliminate it.

Will an Ozone Generator Kill Mold in Ductwork?

To kill mold in ductwork, we recommend the Zackman Scientific Stainless Steel Odor Removal Ozone Generator.

But, in more serious cases, you may need an Ozone Shock Treatment. This technique uses high-grade ozone to kill bacteria and mold in the ductwork. A professional service provider must carry out the service. And, the high ozone levels will require you to evacuate the premises. Exposure to ozone for too long can cause health issues. But it’s effective: the EPA calls it one of the best ways to eliminate harmful bacteria in the air!

How Long Does it Take For Ozone Generators to Kill Mold?

Ozone generators kill off mold and bacteria within 30 minutes of being released into the air. The treatment will be effective for up to ten hours, depending on the level of humidity in your home, so you should make sure tenants are not present during this time.
