Photocatalysis destroysorganic and chemical pollution and bad odours in the air at room temperature and without addition of compounds, to transform them into water vapour and carbon dioxide when the reaction is complete.
Generates negative ions that amalgamate suspended particles. The amalgamated particles, too heavy to stay in the air, fall to the ground.
Destroys germs and bacteria in the air.
The plasma air purifiers (excited gas) act by exciting the oxygen and generate an oxidising molecule that is forced into the room to clean the air. Air is therefore purified not in the device but on the outside. This process is effective on microorganisms such as bacteria and viruses, and volatile organic compounds. A major disadvantage is that this kind of air purification device loads the air with ozone and other free radicals (singlet oxygen, hydroxyl, peroxide, etc.), which are toxic for organisms, causing respiratory tract lesions even at low concentrations; the reaction also emits an odour. This kind of air purification device should therefore not be used in permanently inhabited environments. It has a rather industrial application.
It is very easy to make the right choice: just compare the products. But when product performance is not certified, this becomes impossible.
Certification makes it possible to compare objectively.
The product performance is evaluated according to the same criteria, and the results are expressed in the same unit of measurement, regardless of the country where the products are manufactured or marketed.
A certified product has its performance verified by an impartial, independent and competent accredited body.
Certified products comply with standards.
A product whose performance is certified will work according to the specifications stated by the manufacturer.
