Ozone, UV or plasma? What to choose?


Ozone is a broad-spectrum sterilizer, effective, safe and without persistence. It kills bacterial spores, viruses, fungi and can damage botulinum toxin. One of the characteristics of ozone is the very short contact time whether log1, log2 or log3.

As ozone is a gas, it can treat not only air but also surfaces by diffusing ozone into the water. The result is disinfectant water. Because of its power, for air treatment, ozone generators are to be preferred for shock treatment applications, in human absence. This is the general principle. However, there are some generators that integrate "human presence and human absence" according to the chosen programs. Corona system ozone generators can produce very high ozone concentrations in very large volumes to destroy very resistant bacteria such as listeria. For surface treatment, aqueous ozone (1 to 1.5 ppm) is a very powerful disinfectant. Knowing that some generators can go up to concentrations of 10 ppm. Our ozone generators are mainly produced by corona systems, UV can also produce ozone, but for our applications at lower concentrations.


UV refers to ultraviolet rays with a wavelength of 100 to 280 nm. Our UV products generate ozone but at lower concentrations than our ozone generators and are reserved for certain applications.

Concerning the UV air purifier, it has the same function as the PLASMA, equipped with a UV lamp, an active carbon filter and sometimes a HEPA filter. Its role is to reduce the bacterial or viral load of a space by absorbing the air in a room and destroying the bacteria, viruses and fungi present at a rate of about 3 times the volume of a room per hour.


The plasma is an air purifier equipped with a UV lamp, a titanium dioxide filter, an activated carbon filter, a HEPA filter, a high-pressure plasma electron electrostatic field, a photo electrocatalytic, a photocatalyst, a negative ion generator and an air purification controller. Not only does it destroy viruses, bacteria, fungi, it also filters VOCs (Volatile Organic Compounds).

The air circulation is about 3 times the volume of the room per hour. Its role is to reduce the bacterial and viral load of a room while eliminating VOCs. The goal is to obtain a healthy and soothing air.

Retirement homes and EHPAD

Nursing homes and HPAE are social spaces where large numbers of people interact, exposing them to contamination, the spread of viruses, diseases and harmful particles.


These environments generally lack oxygen and contain odours.

We offer total decontamination and deodorization: premises, rooms, medical equipment, textiles (blankets, sheets, clothes, curtains, towels ...) by different treatments (ozone, plasma, UV ...).

Our solutions respond to the problems of microbiological contamination of air and surfaces by bacteria, viruses and fungi. We bring you solutions to the problem of allergic and infectious outbreaks.

Ozone destroys bacteria, viruses, fungi and moulds in a very short time.

Our ozone cannons completely eradicate contaminating agents, which will allow you to welcome the elderly in the best possible conditions.

Hospitals and clinics

For many years, the development and proliferation of nosocomial diseases in clinics and hospitals has been a scourge that exposes susceptible patients to medical complications.


It is then essential to promote the use of facilities designed to maintain a clean atmosphere of micro-organisms and allergens.

All our generators prevent the multiplication of contamination by using environmentally friendly biocide manufacturing systems.

We offer the destruction of micro-organisms (bacteria, viruses, fungi), VOCs (Volatile Organic Compounds), odours from walls, ceilings and floors.

Frequently Asked Questions

Let's not confuse the ozone layer, which is necessary for life on Earth because it protects us from the sun's UV rays and oil pollution.

Pollutants in the air, nitrogen oxide and organic particles from road traffic and factories, cause abnormal concentrations of ozone when the weather conditions are about to change.

In this case, the source of the problem is not ozone, a natural phenomenon, but hydrocarbons.

Ozone has been used in France for more than 100 years to disinfect waste water.

Ozone has been recognized worldwide for the preservation of food products for decades and has been invested with a double-digit growth in multiple fields of activity: tertiary, agricultural, wine, food processing...

Its overpower is world renowned for destroying bacteria and viruses with very short contact times, leaving no residue. It destroys bacteria and viruses by the principle of lysis unlike chlorine which kills bacteria without destroying them. Consequence: Ozone destroys the biofilm.

The presence of ozone in many areas is the result of technological developments, technical understanding and the willingness of many stakeholders to adopt less polluting production protocols.

Ozone occurs naturally outdoors at a concentration of about 0.03 ppm.

The French National Institute for Research and Safety (INRS) stipulates that an employee must not be exposed to an ozone concentration higher than 0.1 ppm for 8 hours or 0.2 ppm for 15 minutes.

Ozone Expert implements the security of its installations.

Defined common units of measurement

Before discussing the production of ozone generators, the measurement of dissolved ozone in water and many other important information about ozone, we must clearly define the units of measurement used in the world of ozone. There is some jargon and assumptions of established knowledge in the "ozone world", so take some time, read below and make sure we are speaking the same language.


Ozone generator output units

g / h = gram per hour

The most common measure of the overall output of the ozone generator. This measures the weight of ozone in grams that is produced in one hour by the ozone generator. To make this determination, the flow of gas through the ozone generator will be required, as well as the quantity of that gas which is ozone. This will give sufficient data to provide an estimate in g/h.


mg /h = milligrams per hour

Commonly used to measure the production of smaller ozone generators. 1 g / h of ozone = 1,000 mg / h of ozone.


kg / h = kilograms per hour

Used to measure the production of very large ozone generators. 1 kg / h of ozone = 1,000 g / h of ozone.


lb / day = pounds per day

Used to measure the production of large ozone generators in English units. 1 lb / day of ozone = 18.89 g / hr of ozone.


Ozone concentration units

w t% = percentage by weight

This is the percentage of ozone gas in a given volume (as opposed to volume). This provides a concentration of ozone gas in the gas flow through the ozone generator.

g /m3 = grams per cubic metre

Best method for quantifying the ozone concentration of an ozone generator. This will provide the grams of ozone present in a given cubic metre of feed gas through an ozone generator.


ug / ml = micrograms per millilitre

Used to measure ozone concentration in certain applications. It is the same as g / m3. 1 ug/ml ozone = 1 g / m3 ozone.


ppm = parts per million

Used to measure the concentration of ozone in ambient air. Quantifies parts of ozone gas in every million parts of other gases (normally air). 1 part of ozone in 1 million parts of air will be 1 ppm. Note: ppm can be measured by weight or volume. In ozone, global ppm is almost always measured by volume.

Also used to measure the concentration of ozone in water. 1 ppm = 1 mg / I of ozone in water.

ppb = parts per billion

Measures low levels of ozone in ambient air. 1 ppb = 0/001 ppm.

mg / I = milligrams per litre

Normally used to measure ozone in water. 1 mg / I = 1 ppm ozone in water.

Can also be used to measure the concentration of ozone in the air. 1 mg/ I ozone in air = 1 g/ m3 = 1 ug / ml = 1 gamma. These are all used interchangeably.

Flow measurements for feed gas (air or oxygen)

LPM = litres per minute

Metric measurement of feed gas flow through the ozone generator. Sometimes indicated in L/ min. This can be oxygen or air flow. 1 LPM = 2.1 1 SCFH

SCFH = standard cubic feet per hour

English measurement of feed gas flow through the ozone generator. This can be oxygen or air flow. 1 SCFH = 0.47 LPM

m3 / h = cubic metres per hour

Metric measurement of feed gas flow through the ozone generator, mainly used for large scale flows and ozone generators. This can be oxygen or air flow. 1 m3 / h = 16.66 LPM

Disinfection measure

Disinfection rate

LOG1 = 90% LOG2 = 99% LOG3 = 99.90% LOG4 = 99.99% LOG5 = 99.99% LOG6 = 99.90% LOG7 = 99.99
