Air Purifiers

We have a wide range of Air Purifer and Disinfection Units for many applications.

Wellissair uses a new, innovative, and disruptive patented technology that efficiently generates and expands Hydroxyl Radicals (OH·) in order to trigger Advanced Oxidation Processes (AOP) for the elimination of up to 99.9% of pathogenic microorganisms (viruses and bacteria), at the same time as reducing Volatile Organic Compounds (VOCs) and PM particles.

The Wellisair application field is very wide and diverse: Hospitals, laboratories, food conservation, public spaces, education buildings, transports, offices, veterinarian or malls among many others.

Hydroxyl Radicals are not only highly efficient when it comes to disinfecting both the air and surfaces, but they are also a method which is completely harmless to humans, according to a study published in the scientific journal IJOER “International Journal of Engineering Research and Science”.

In the 1970s, Military Defence used OH· in the atmosphere to develop this technology for CBR (Chemical/Biological/Radiological) warfare. It was first commercialized in the 1990s for use in European hospitals and has proved to be very effective at removing harmful substances such as bacteria, germs and viruses, harmful gases, mould, and respiratory allergens, which can all lead to a contaminated and harmful environment to humans.

Within the Reactive Oxygen Species (ROS), Hydroxyl Radicals (OH·), when used in small concentrations, can be employed to carry out biocidal functions on viruses, bacteria, allergens and mould, in order to erode any organic compounds found in the air and turn them into minerals or harmless water-soluble organic compounds.

The OH· Hydroxyl Radical is the most important natural oxidant in tropospheric chemistry. This molecule is often referred to as the atmosphere's "detergent", as it reacts with a large number of pollutants to kick-start the purification process. It also plays an important role in eliminating Greenhouse Gases, such as Carbon Dioxide and Methane.

Advanced Oxidation Processes (AOP) are particularly powerful as they are able to destroy pollutants without concentrating or transferring harmful substances into the surrounding environment. This allows for a total or almost total mineralisation of all organic pollutants, meaning that the vast majority of organic compounds are destroyed, especially when dealing with non-biodegradable compounds such as Organochlorines, PCBs, PAHs, etc. It's also a very clean and safe technology.

Wellis Air Disinfection Purifier WADU-02

Wellisair is a patented device with a disruptive and innovative technology to disinfect, purify and clean the air and surfaces with nature’s own mechanisms. Wellis air uses advanced technology that effectively generates and expands Hydroxyl Radicals (HO) that by oxidation substantially eliminates virus, bacteria, allergens, moulds, odours, and VOC’s (volatile organic compounds) up to 99%.

K7 Air & Surfaces Purifier Disinfection Unit

K7 cleans, purifies and disinfects the air and surfaces from all hazardous elements using the air cleaning methods found in nature applying both Kleenfan and Wellisair technologies. The state-of-the-art, innovative and patented K7 technology generates and spreads hydroxyl radicals (OH) which by using oxidation eliminates 99.9% of the existing viruses, bacteria, allergens, mold, odours and volatile organic compounds (VOCs).


Kleenbox High Efficiency Air Purifier Unit Low noise ventilation box with three stages of filtration with disinfecting action. A flat pre-filter with a broken surface, a compact F7 filter and finally an absolute H14 filter. Efficient to return to the room the free air of volatile organic compounds, bacteria, viruses, bad smells, pollen and dust.

Zerobox B

The Zerobox is a Low Noise Ventilation Box with Photocatalytic Technology for Air Disinfection and Purification. Ventilation box that does not emit noise thanks to the 5 cm acoustic insulation it has. Equipped with fans with a disinfectant action thanks to the application of Kleenfan technology, which acts in the same way as nature, carrying out an oxidation process equal to photosynthesis. The UV-A rays emitted by an LED lamp hidden in the system act on the titanium dioxide in the turbine and eliminate the pathogens from the air that come into contact with it. Effective in returning the air free of volatile organic compounds, bacteria, viruses and bad odours to the room.

Mia Air - Air Purifier HEPA H13

Specifically designed to clean air pollutants, Mia Air offers superior indoor air quality that will improve the quality of life. MIA Air continuously measures the air quality without affecting the ambient temperature. This improves the quality of life by continuously cleaning the indoor air at a frequency varying according to the size of the room and the amount of pollutants. It is one of the highest capacity devices with the ability to clean a room of 100 m2 (1075 sqft) on average 2* times per hour. *The average ceiling height is considered as 3 meters (9.843 ft).

Mia Air Compact

Mia Air Compact’s practical and sleek panel design, allows you to control the environment of both you and your loved ones manually; by selecting the fan speed, setting the timer and keeping track of the filter life with the filter change signal.
