INDOOR POLLUTION

INDOOR POLLUTION

At home and in the office we are surrounded by elements that are invisible, let them enter our body simply breathing, without realizing it. Outdoor and indoor air pollution is considered by the World Health Organization as the main environmental risk factor of population’s health.

%

Time of day that we spend indoors

Air amount that we breath in a minute

%

Indoor pollution is 5 times higher than the external one

Millions of particles ingested every minute

%

The amount of PM1 compared to all the particles in the air

Millions of particles ingested with each breath

The most known air pollution factors derive mainly from the transport sector, industrial sector, activity of power plants and incinerators, domestic heating, agriculture use of pesticides and mining dust. Much less known is the pollution of domestic environments which, in addition to being sensitive to external agents, is also sensitive to the internal ones caused by products present in every home:

Furnishings
Glues
Carpets and moquette
Paints
Detergents
Spray cosmetics
Solvents
Liquid waxes
Insecticides
Sealants
Spray and hygiene products
Soaps

These products cause other pollutants: fine dust, mold, mites, bacteria, carbon monoxide, nitrogen dioxide and a large family of molecules known as “volatile organic compounds”. The category of volatile organic compounds (VOCs) includes a series of substances all containing carbon in complex mixtures, which easily evaporate already at room temperature. More than 300 are known, most of all aliphatic hydrocarbons, terpenes, aromatic hydrocarbons, chlorinated hydrocarbons, alcohols, esters, ketones and aldehydes.

Photocatalysis with visible light, the WIVactive innovation

WIVActive integrates in one product effective lighting with an air sanitization system based on nanomaterials and the photocatalysis process, capable of eliminating pollutants, bacteria and viruses, such as Betacoronavirus. The WIVActive system uses visible LED light with a calibrated spectrum to activate the photocatalytic process on particular ceramic filters, which thanks to the strong oxidizing power released, eliminate harmful substances and destroy bacteria and viruses. This patented process lays its foundation on the protection of people and the environment.

Coating

The nanomaterials are applied to the surfaces through a specifically developed coating treatment (fixing the nanocomposite). The particular chemical composition of this substance, based on a special form of titanium dioxide loaded with silver and other elements, means that it is activated simply thanks to the action of white artificial light, even in the absence of UV rays.

The silver ions

The finely dispersed metallic silver molecules react with the water molecules present in the air and release silver ions which allow the air to be purified by exerting an antibacterial action.

Heart of the system: the GEAR BOX

 

Gear Box is where photocatalytic activation takes place through visible light and no longer UV. Different LED sources were analyzed, different optical schemes to illuminate the filters and light’s energy levels necessary for photocatalytic activation, to achieve the creation of the Gear Box, a patented system that allows you to illuminate in an homogeneous, effective and calibrated way, in terms of light spectrum, the individual filter elements. This allowed the achievement of maximum effectiveness of filter.

The patented lighting scheme has allowed the optimization of the system pressure drops in order to have the maximum efficiency of air flow for the filter. The use of a special magnetic levitation technology for the fan, in combination with the light scheme, has allowed the reduction of power consumption, increase in flow rate and above all the reduction of noise in a very significant way. Only 13dBA of noise for a filtration system that is enormously quieter than the current ones on the market.

Certifications

The WIVActive technology places its credibility on the certifications issued by the most important Italian and European laboratories. For our concept of “research” and “experimentation”, scrutinizing our results was conditio sine qua non to be able to place on the market products that expressed the maximum in terms of technology and effectiveness. Last but not least: “do not harm the health of people but bring well-being into daily indoor life”.
