POLLUTANTS voc
NITROGEN DIOXIDE
Nitrogen dioxide, despite being a typical outdoor air pollutant, originating mainly from traffic, also falls among the most common indoor air pollutants.
Especially in Italy, where we use gas extensively, both for heating and for cooking. Exposure to this compound may result, in the absence of adequate ventilation, even greater than that of the outside air.
The main sources of oxide and nitrogen dioxide are: kerosene radiators, gas-free stoves and radiators, and tobacco smoke. In homes, concentrations of less than 0.1 mg per cubic meter are generally found, however higher levels (greater than 0.2 mg per cubic meter) may occur, especially when cooking food with gas stoves or during use of kerosene stoves.
Health effects
Nitrogen dioxide has a pungent odor and can cause irritation to:
- Eyes
- Nose
- Throat load and cough.
It can also cause alterations in respiratory function, which can occur in sensitive individuals, such as children, asthmatics or chronic bronchitis.
An early symptomatology of the upper airways in subjects with pulmonary disease can occur starting from concentrations equal to 0.2 mg / metrocubo.
WARNING!
Ventilating the premises without eliminating the emission sources is of no use. Because once the frequency of ventilation is reduced, the problem recurs.
A big source of pollution is also the garage: if connected directly to the house it can convey the exhaust gases from the vehicles.

Measures to reduce exposure
Gas
Devices must be regularly checked
Kitchen
The kitchen must be well ventilated and when cooking use the air extractor with exhaust outside.
Smoke
Carcinogens produced by cigarette smoke stagnate indoors.
Heating
Have expert staff check: boilers, chimneys and chimneys.
THE SOLUTION
Integrated vacuum cleaning system
A simple and durable integrated system. The only one in the world that expels micro-dust, mites, allergens, pollutants, bacteria and viruses with ordinary cleaning.
