What are ozone generators and how do they work?
Ozonators, also known as ozone machines, are ozone-producing equipment that produce ozone gas on purpose. When sold as air purifiers for use in populated indoor environments, they are advertised as being both safe and effective (though these claims are generally false). This page addresses machines that intentionally produce ozone rather than as a byproduct. As a result of their internal mechanics, ionisers and electrostatic precipitators produce ozone as a byproduct.
You’ve probably heard about ionisers. They were once very popular and were frequently used in homes to purify the air and eradicate odours. However, Consumer Reports Magazine revealed the units as potentially causing more harm than good in the spring of 2005, when it was discovered that several of these devices might emit dangerous quantities of ozone. Despite the fact that ozone is produced as a result of these ionisers and at a lower level than ozone generators, the federal government has begun a tighter regulating procedure for any air purifier that produces ozone, whether purposefully or as a byproduct.
The use of ozone generators in occupied places has not been permitted by the federal government, and the California Air Resources Board (CARB) has tight regulations for air purifiers supplied in the state to ensure that toxic ozone levels are not produced.
What are the workings of ozone generators?
As air goes through the equipment, a diagram of how ozone producers work is shown.
ELECTRICAL CHARGE IS APPLIED TO THE AIR THAT PASSES THROUGH OZONE GENERATORS. SOME NORMAL OXYGEN ATOMS ARE SPLIT APART INTO UNSTABLE SINGLE ATOMS, WHICH BOND WITH OTHER O2 MOLECULES TO FORCE O3.
Ozone is created by dissolving oxygen (O2) molecules into single atoms, which then bond to additional oxygen molecules in the air to generate ozone (O3). According to the International Association of Certified Indoor Air Consultants, they do it in one of two ways (InterNACHI).
Ozone generators produce ozone by:
Silent corona discharge: These machines make ozone by dividing regular oxygen molecules in the air into single atoms using an electric discharge. Ozone is formed when these atoms combine with other O2 molecules in the air (O3).
Ultraviolet radiation: The sun’s ultraviolet light separates O2 into individual oxygen atoms, which is similar to how ozone is formed. This procedure, according to InterNACHI, is less efficient than corona discharge.
What are the benefits of using ozone generators to purify the air?
Why would someone use ozone to filter the air inside their home if it is so dangerous? As previously stated, ozone is a highly reactive gas that can alter the chemical composition of several airborne compounds. Manufacturers’ claims are based on this idea.
Companies that offer ozone generators may use phrases like “activated oxygen” or “clean air” to suggest that ozone is a healthy form of oxygen, but ozone is actually a harmful gas that is not the “same as air,” as some manufacturers say. Devices that generate ozone are frequently promoted as odour removers. They are ultimately employed to remove organic chemicals from the atmosphere. However, because of the risk to one’s health, an ozone generator should only be used if there are demonstrable benefits.
