How does an ozone generator work?

An ozone generator purifies the air by first creating and then releasing ozone into the air.

Ozone itself is a form of oxygen, but where regular oxygen consists of two atoms, ozone has three. This third atom detaches itself from the ozone particle and latches itself onto pollutants. Once attached, it will change the pollutant’s atomic structure before detaching itself once again and finding the next one.

It works great on smoke, cooking and pet odors, as well as actual mold and their spores.

How long should an ozone generator run?

It depends on several factors. On average, it should run anywhere between three to six hours per room – depending on the strength of the actual ozone generator you are using and the size of the room.

If you are doing your whole house and will be moving it around from room to room, then it will have to run for the entire day.

Many of these machines come with built-in timers, which is a safety feature. It works by automatically switching the ozone generator off after a few hours.

Also, it’s not uncommon for smells to return after a few days. Not to worry, because the odors won’t be nearly as strong as it was before. However, in such an event, it would be best to rerun the machine to eliminate whatever odors remain.

Ozone generator safety precautions

Ozone generators are great, but there are health risks to humans and pets with the use of these machines.

Ozone generators work by creating massive amounts of ozone. Ozone, in small quantities, is good but can create health issues when in large numbers. Breathing in excessive amounts can impair the body’s natural ability to fight respiratory infections; it can worsen asthma, cause chest pains, coughing, and throat irritations. Therefore, it’s best to keep people and pets out of the room while the ozone generator is running. Also, keep them out for two or three hours after afterward, while the remaining ozone dissipates.
