Due to it’s unique chemical composition and highly reactive nature, ozone is able to quickly and efficiently disinfect and oxidize a wide variety of microorganisms, faster than any other commercially available oxidant. Ozone begins oxidizing everything immediately upon contact, powerfully breaking down bacteria and viruses.
As ozone decontaminates, it naturally decomposes back into oxygen, without leaving toxic residues, making it safe for the environment.

Ozone, or trioxygen, is a fast-acting oxidizing disinfectant made up of three oxygen atoms (O3). Ozone occurs naturally in the upper atmosphere, or stratosphere, when the sun’s light splits oxygen molecules (O2) into separate atoms. When these single atoms bond with other oxygen molecules, they form ozone, protecting us from the sun’s harmful ultraviolet rays.
The word “ozone” comes from the Greek “ozein” meaning “to smell”, and was discovered by a Swiss-German chemist and professor at the University of Basel (Switzerland) Christian Shönbein. Shönbein identified it as a different form of oxygen and gave it the name Ozone in 1840, because of the peculiar smell that it produces, such as what occurs during storms.
- The most potent oxidizing disinfectant to decontaminate water and sanitize surfaces
- Ozone is the toughest microbiological control agent
- Kills pathogens faster than any other commercially available oxidizing agent
- Naturally decomposes back into oxygen
- Safe for the environment leaving no toxic residue
- Ozone does not affect Ph levels on it’s own
- Improves filtration by enhancing the coagulation and flocculation (bringing smaller particles together to form flocs) of organic material
- Assists biological filters by partially oxidizing organics into biodegradable compounds that are easier to remove from water
- Oxidizes metals such as iron, manganese, and more
- Ozone is a highly reactive compound produced from the oxygen in the air. It is not possible to store it, and there is no need, making bulky hazardous containers unnecessary.
