What is an air purifier?
An air purifier is a device that cleans the ambient air by eliminating impurities and allergens
such as fine particles, pollens, dust, dust mites, bacteria and viruses. It sucks in indoor air and passes it through various filters to capture particles and purify them.
There are different types of filters used in air purifiers, such as HEPA (High Efficiency Particulate Air) filters
which are able to capture the finest particles, as well as activated carbon filters to remove odors and gases. harmful. Thus more and more electric hand dryers
, Hepa vacuum cleaners
or cleaning equipment rejecting air into the atmosphere are equipped with these HEPA filters. Some air purifiers also use advanced technologies such as UV-C sterilization
or ionization to eliminate bacteria and viruses.
Air purifiers are often used to improve air quality in homes, offices, schools, hospitals, and other indoor spaces. They can be particularly useful for people with allergies, asthma or other respiratory problems, as well as reducing the spread of contagious respiratory diseases such as Covid.
How does ultraviolet disinfection work?
Ultraviolet (UV) disinfection is an air or water purification method that uses high-energy UV light to kill microorganisms such as bacteria, viruses, and mold. This disinfection method is commonly used in drinking water treatment facilities, hospitals, laboratories, food processing plants, pharmaceutical plants, and other environments where hygiene is essential.
The principle of UV disinfection is simple. The UV light is emitted by a special lamp which is placed in a disinfection chamber. When contaminated water or air passes through this enclosure, UV rays interfere with the DNA or RNA of microorganisms present in the water or air, preventing their multiplication and reproduction. It can also kill them if exposed to UV light long enough.
It is important to note that UV disinfection does not filter particles, chemicals or physical impurities from water or air. It focuses only on the elimination of microorganisms.
The effectiveness of UV disinfection depends on many factors, including the quality of the UV lamp, the duration of exposure to UV light, the quality of the water or air being treated, and the design and maintenance of disinfection equipment. It is important to follow the manufacturer's recommendations for effective and safe use of UV disinfection.
