UV Air Purifiers
Commercial and residential UV air purifiers are gaining their popularity and they are used by millions of people all over the world. This type of appliances are efficient in eliminating germs such as germs, viruses, bacteria, fungi and mold at offices, homes, basements, commercial buildings, heating, ventilating and air conditioning systems.
Ultraviolet is a form of radiation with very short wave length and it can't be perceived by the human eye. It is studied since the 1930s and due to the fact, that it is not visible, it is technically can't be called a “light”. The work of UV air purifier differs from air cleaner with filters, because pollutants don't come through the unit. UV appliance releases the right amount of energy and break organic molecular bonds.
Ultraviolet air purifiers are often installed in metal air duct systems and the faster the air circulation, the more efficient the performance of UV unit. Besides, in some government buildings, like hospitals and schools, the installation of UV appliance in the HVAC system is a requirement. These cleaners are perfect for extremely polluted areas like kitchens or bathrooms.
Ultraviolet cleaner still has one drawback, as it is good for eliminating germs and living microorganisms, but it is not effective against dead particles, like pet dander, pollen, chemicals, smoke or odor. That's why UV air purifiers are often combined with other types of air filtration systems, like HEPA, activated carbon or ionizers, what increases their efficiency considerably. These appliances require low maintenance, as the UV light bulb should be replaces every 1-3 years, depending on the design and usage frequency.
