The Nuvohla / Wellisair device is placed either on the floor or on the wall. Its packaging has all the necessary accessories for both the floor and wall installation.

Our devices do not filter the air! We offer an active air and surface purification technology. Our devices are effective both in the air and on the surfaces throughout the space as their technology does not require air to flow through our unit, instead it permanently releases on a 24-hour basis hydroxyl radicals which seek out and kill pathogenic microorganisms, whereever thet meet them. Most of our tests are performed on surfaces in order to show the active nature of the solution we offer. We are able to compare our validated results with any other technology worldwide. With OANIS’s devices, we kill the airborne virus or pathogen as soon as it enters the room regardless of its size, because our data “fills” the operating spaces (even where it does not catch the human eye) and do not wait – like the competition – neither the ingress of air into the machine nor the periodic cleaning of the cleaning service (mopping etc).

Most of the pathogenic microorganisms belong to the family of bacteria. The physical characteristics of bacteria are divided into two groups:

Bacterium Gram “+”: Characterized by the presence of two layers on the bacterial wall: The outer cell wall crossed by protein chains, lipoic acids (among others) and the cytoplasmic membrane (inner wall).

Bacterium Gram “-“: These bacteria have three layers in the cell wall: The outer membrane is made up of phospholipids and liposaccharides, the middle layer is similar to the outer Gram “+” but much thinner, and the inner membrane is the same cytoplasmic membrane with the inner membrane of Gram “+” bacteria.

The advanced oxidation process (AOP) based on hydroxyl radicals can attack both types of bacteria. This is because they both have acid and protein chains that are vulnerable to oxidation.

The oxidative reactions that occur cross the bacterial membranes, modifying their morphological structure (eliminating the membranes), until they reach their genetic information, so that these irreversible lesions kill and kill the bacteria.

To determine the effectiveness of OH technology against bacteria, various tests were performed on air and surfaces, such as:

Bacillus Subtilis:

Reduction of the concentration of Bacillus Subtilis plaque forming units per milliliter (PFU / ml) in the air.

Reduction of Bacillus Subtilis plaque formation units per milliliter (PFU / ml) on the surface 60 minutes after the start of the test.

Staphylococcal disease:

Reduction of the concentration of Staphylococcus Aureus plaque forming units per milliliter (PFU / ml) in the air.

Reduction of the concentration of Staphylococcus Aureus plaque forming units per milliliter (PFU / ml) on the surface 60 minutes after the start of the test.

Salmonella:

Reduction of the concentration of salmonella plaque forming units per milliliter (PFU / ml) on the surface 4 hours after the start of the test.

The results of these tests were very satisfactory, because, within a few hours of exposure, 99.9% of the bacteria were removed, both in the air and on the surface.

Around the 1990s, NASA researchers created hydroxyl radicals and other peroxides to prevent the accumulation of organic compounds in the spacecraft during space missions. Since then, interest in the safety and efficacy of these molecules against volatile organic compounds, bacteria and viruses has increased dramatically.

Air purifiers fully comply with the restrictions on “use of hazardous substances in electrical and electronic equipment”.

We should not confuse hydroxyl radicals in the environment with biology.

Airborne hydroxyl radicals cannot penetrate our body, nor animals, insects or plants, due to their coexistence with them during evolution.

While the production of hydroxyl (OH ·) radicals is safe, ozone (O3) and hydrogen peroxide (H2O2) emissions must meet all the requirements of international health regulators.

The maximum recommended ozone emission is 0.05 ppm according to the WHO (World Health Organization), OSHA (Occupational Safety and Health Administration) and the FDA. The maximum hydrogen peroxide emission recommended by OSHA for a 10-hour business day is 1 ppm.

The OH technology-based cleaner fully complies with these restrictions, as 0.016 ppm is the maximum ozone emissions (reported by Intertek Laboratory in 2018) and 0.64 ppm is the maximum hydrogen peroxide emission.

OH technology purifiers are an extremely versatile product that can be used to clean and disinfect premises in a wide range of areas. OH technology cleaner eliminates viruses and bacteria, reduces volatile organic compounds (VOCs) and also PM particles, which means that it can be used for different purposes:

Health sector:

Multiple tests on different pathogens have been performed to certify the effectiveness of the disinfection effect

The results show a miscarriage rate of 90-99%, which was tested especially in health care areas such as waiting rooms, surgeries, emergencies, beauty centers, homes, dentists, etc.

Food industry:

from the beginning of the food production cycle, cleaners are required to eliminate volatile organic compounds and odors from farms, fertilizers, processing or packaging centers, etc.

OH technology cleaner reduces about 95% of formaldehyde, ammonia and atmospheric particles from these activities in a relatively short period of time.

Food preservation:

the oxidation effect of OH eliminates components such as ethylene present in the air and accelerates the ripening process of fruits and vegetables. This process allows the food to be stored longer and thus avoiding any financial losses caused by food spoilage.

Veterinary:

there is a large concentration of microorganisms found in veterinary centers due to all the animals they visit. This is why the integration of a unit in such centers will help to avoid any contamination between the animals, while keeping the visiting rooms clean and disinfected.

Buildings (private sector):

People spend much of their day at work, which means that setting up a unit in offices and administrative centers will provide a clean work environment free of allergens, viruses and bacteria, offering excellent and improved air quality for everyone.

Public Spaces:

places with high concentrations of people, such as shopping malls, cinemas, government buildings, lounges or gyms. The cleaner can be used to eliminate the smells of the locker rooms and to keep the surfaces free from any allergenic and pathogenic elements for a cleaner and more pleasant space.

Schools and kindergartens:

One of the main places where higher rates of infection tend to occur is the training centers, which makes it particularly necessary to maintain classrooms, bathrooms and dining rooms free of pathogenic microorganisms or any allergens. OH technology has been tested with a 99% elimination rate in just a few hours.

Except completely harmless? For humans, the cleaner is also an ideal disinfection product that can be used in schools and kindergartens, where children share indoor spaces for long periods of time throughout the day.

Transport:

Public transportation is usually the equivalent of small enclosed spaces where a large volume of microorganisms will pass through in a day, resulting in the accumulation of numerous unpleasant odors and VOCs. This means that keeping these areas clean and often disinfected is especially important in order to maintain a pleasant space for everyone and to avoid any contamination.

It is important to note that maintaining an environment free of pathogens, maintaining high air quality and removing unpleasant odors is a necessity in all walks of life.

Therefore, while some applications of technology are more relevant to certain industries, technology has many different uses and is effective in improving air quality and surface cleanliness for any location.

Hydroxyl radical (OH) technology is extremely flexible and allows air and surfaces to be effectively cleaned and disinfected. Given the larger operating range of this technology, it has four main uses:

Virus removal:

OH technology has been tested against different viruses with different characteristics (morphology, entanglement, etc.) and in different environments (wet and dry).

Some of the best known examples are: Respiratory Circulatory Virus (RSV), Rotavirus or Coxsackievirus (hand-foot-mouth)

The results obtained from the OH technology test on non-wrapped viruses show that it is much less effective in wet conditions than in dry environments, whereas when dealing with wrapped viruses, moisture favors the advanced oxidation process and therefore, they viruses are eliminated more effectively in wet conditions as opposed to dry environments. The results obtained from these tests show a removal rate of 90-99%, making OH technology ideal for viral disinfection of both air and surfaces.

This feature makes the OH technology cleaner ideal for hospitals, laboratories, analysis clinics, veterinarians or beauty salons. In other words, mainly for the health sector, research centers and animal health.

Bacteria removal:

Another important group of pathogenic microorganisms are bacteria, which have caused many serious diseases throughout history.

OH technology has been tested on many of the major types of bacteria, both Gram “+” and Gram “-“, such as Bacillus Subtilis (resistant to extreme temperatures and radiation), Staphylococcus Aureus (resistant to disinfectants such as chlorine) or Salmonella (resistant to various antibiotics).

The results of these tests showed an average elimination rate of 99.7% in bacteria within just a few hours of exposure.

OH technology is ideal for eliminating bacteria and viruses in order to prevent transmission between humans or animals. This makes it particularly useful for use in any health rooms, animal centers, schools, public transportation or crowded locations.

Air quality: Reduction of volatile organic compounds (VOCs) and atmospheric particles (PM):

In addition to microorganisms, there are several other types of compounds that can be found in the air, which cause serious pathologies and / or act as allergens for a large percentage of the population. The scavenger performs a series of reactions to oxidize VOCs and PMs, converting them to harmless compounds.

Several tests performed on formaldehyde (VOC) and PM1, PM2.5 and PM10 particles show their almost complete disappearance after only half an hour of exposure.

This feature makes OH technology ideal for installation in food industries, food storage, laboratories, public transport or any other place where such compounds or atmospheric particles are commonly formed.

Air quality: Odor reduction (VOCs):

VOCs are formed in part using formaldehydes, ammonia and toluene, which are responsible for an unpleasant odor released when converted from a liquid (or solid) state to gases.

Since maintaining a toxin-free, pleasant and odorless environment is very important when referring to public places (administration, gyms, etc.), veterinarians, farms, public transport or offices, OH technology has been tested in all these associations by presenting 80-99% reduction within just a few hours of exposure to these advanced oxidative reactions.

OH technology devices use hydroxyl radicals to inactivate 99.9% of microorganisms, eliminate odors and reduce volatile organic compounds (VOCs) and particles. Although this technology has been shown to be safe and effective against certain viruses and bacteria, a review of the most common pathogens in training centers is necessary to determine if OH technology is effective in these areas.

The most common infectious diseases among school-age children mainly affect the upper respiratory tract or gastrointestinal tract.

Among the pathogens that affect the respiratory tract, we find:

1. viruses that lead to the common cold (the most common causative agent is the rhinovirus, although respiratory contagious viruses, Parainfluenza viruses and viruses of the Adenoviridae and Coronaviridae families are also common)

2. the flu virus, the one that causes a sore throat (although it is usually a symptom of a cold or flu, in 1 in 3 cases in children it is due to Streptococcus pyogenes – also called Streptococcus group A, which can also cause conjunctivitis),
3. the bacterium Bordetella pertussis leading to whooping cough and

4. the bacteria that cause meningitis (the most common causative agent is Neisseria meningitidis although Streptococcus pneumoniae and Hemophilus influenzae are also related).

All of the above are transmitted through the respiratory tract by droplets and / or microdroplets that are released when they speak, breathe, cough, etc., and are therefore sensitive to hydroxyl radicals.

Regarding the transport of pathogenic microorganisms from the hands or surfaces, the following has been noted in a large number of studies:

Depending on the characteristics of each microorganism (such as its external structure) and the environment (such as moisture or exposure to hydroxyl radicals), the time it can take to maintain a surface will either be extended or reduced.

“Unwrapped” viruses are generally more resistant than “wrapped” viruses, but this is not always true: the “wrapped” flu virus can remain on a dry surface for 48 hours, while the “unwrapped” virus SARS- CoV can survive up to 96 hours, for example.

In one class, water sources, stationery, keyboards, faucet handles, desktops, and others function as carriers, containing a high general presence of viruses and bacteria.

The effectiveness of the OH hydroxyl radical technology of our device in the aforementioned pathogens has already been tested in different laboratories and has been certified. According to the sampling (air or surface), humidity conditions, time of exposure to hydroxyl radicals and the characteristics of each microorganism, the reports show reduction rates of up to 99.9%. Results that allow us to conclude that OH technology is effective in disinfecting and cleaning educational areas, protecting our children and teaching staff.
