How Long To Wait To Run An Ozone Generator?

An ozone generator can be a dangerous device, as EPA has warned us multiple times. While given a choice, we would not even start the machine, but this is not what this post is about. What we do have here is the official guideline from most ozone manufacturers. All the information you need will be touched on, like how long it takes for ozone to dissipate or how the ozone handles microorganisms. This post should give you a rough idea of how to use an ozone generator at home without causing too much harm.


How Long Does It Take For Ozone To Dissipate?

Ozone will last between 30 minutes to 4 hours for the third oxygen atom to break apart and revert into oxygen on a higher concentration level. On a lower concentration level, ozone will typically take 30 minutes to 1-2 hours to break down into breathable oxygen. To be on the safe side, wait at least 4 hours only to return to the room after shutting off an ozone generator. Room size, temperature, dust, and contaminants will play a part in ozone dispersion in the air.

How Long To Run Ozone Generator In A Room?

Generally, the ozone generator should be running for at least 3 to 10 hours, depending on the room size. For an entire home, at least 25-30 hours of continuous operation to kill off most pollutants. Avoid staying in the room or finding a place to stay while an ozone generator is still active.

How Do You Detect An Ozone Leak?

2 common methods are used to detect an ozone level in a home. First is Draeger Gas Detection Tubes (Draeger-Tubes), which detect hundreds of different gases. Residual ozone becomes sensitive to humans in the 0.01-0.03 ppm range. Draeger tubes are glass vials filled with a chemical reagent that reacts to a family of chemicals, including ozone. A calibrated 100ml sample of air is drawn through the tube using the manual internal bellows pump for the sample. The Second is via a portable or wall-mountable ozone detector or air quality monitor. The device’s built-in sensor will measure the ozone level inside a room or home. Simply leave the device in the desired location for a couple of minutes, and the outcome will be displayed on the digital screen.

How to Use an Ozone Generator in The Home

Ozone is hazardous for living organisms to breathe, including humans, pets, and plants. It does play a role in killing bacteria, mold, odor and even insects crawling underneath the bed. So if you have exhausted all other options and have to resort to an ozone generator, please read the product instruction manual first. All ozone generators are set up differently with their unique capabilities and features. If this is your first time using an Ozonator, please go through the safety precautions steps below.

  • No living things are allowed – Never stay in the same room whenever an ozone generator is working. If you want to cover an entire house, find a place to stay while the device is running.
  • Set a shutdown timer – Most Ozonator comes with a pre-set timer that you can select to power off the machine when time is up. If the particular model does not come with a timer, cover your mouth/ nose and manually turn off the device.
  • Cover or remove valuable items when an ozone generator is active – Ozone atoms do not mix well with metallic things or paper. For bigger objects, try covering them with a blanket.
  • Wait at least 4 hours before re-entering the room that has gone through ozonation – It will typically take 30 minutes for ozone to start settling down and become oxygen again. The longer you wait, the less likely ozone gases will still be lingering in your home.
  • Do not run an ozone generator in a high humidity environment – The moisture will cause damage to the arcing inside the machine. You can, however, run the machine at warm or cold temperatures.
  • Regular maintenance – Some ozone generator comes with a collector plate that requires cleaning every 2-6 months. If you are a heavy user, check for fine dust or oily residue on the output area, as it will decrease the machine’s performance and durability.

Before we begin, let's get this out of our chest. An ozone generator is not an air purifier or ionizer and you should not use it at home. It generates ozone that is smelly and harmful to our lungs. Worst still, ozone is highly reactive to other chemical substances that can even generate more toxic gases. Instead of getting an Ozonator, consider getting an Ozone-free HEPA air purifier that is effective yet will not post any side effects to your health.

What Is Ozone?

Ozone (O3), AKA activated oxygen, is a natural gas produced by UV light from the sun. Ozone contains three oxygen atoms rather than the two atoms in oxygen (O2). In the atmosphere, the ozone layer acts as a shield to reduce the sun's ultraviolet rays intensity. The pungent and colorless gas occurs naturally, often as a result of lightning strikes during a thunderstorm. At ground level, ozone is an air pollutant that triggers chemical reactions with other particulates. It is the second most powerful sterilant globally, used to destroy mold, bacteria, viruses, and odors.
