HIGH EFFICIENCY PARTICULATE ABSORBING/ARRESTATIC E TYPE FILTER works by mechanical filtration and diffusion to trap airborne germs and allergens within it's densely-packed fibre. It clears out up to 99% of airborne allergens and germs up to 0.3 micrometer particle size and also doubles up to improve the durability and performance of subsequent filtration mechanism. ADVANCED UV NANO PHOTOCATALYTIC OXIDIDATION results from the interaction between UV light rays and titanium dioxide Ti02 filter. Reactive oxidants (OH) and Superoxide anion (02) produced in the process attached instantly onto airborne germs and eliminates them by oxidising and weakening the cell membrane and protein coat. ADVANCED ELECTRON SPRAY IONIZATION produces more than 25 million Negative Ions consisting of Superoxide Anions, Hydroperoxyl Radicals and Hydroproxide Radicals. They purify the air by attaching onto airborne allergens thus making them too heavy to stay in our breathing zone. ADVANCED MICA CORONA DISCHARGE produces controlled ozone O3 concentration level for air sterilisation with its incredible oxidation capacity. Ozone proactively oxidises and weakens cell membrane and the protein coat of airborne germs to eliminate them. Additionally Ozone also freshens the air quality readily with its effective odour control to prevent unpleasant smells. POWER AMPLIFIER produces the highest controlled ozone concentration up to 360mg/hr to perform a series of effective surface sanitisation activities. With the high-power oxidation, surface-bound germs are eliminated quickly for a more thorough clean. ADVANCED AIR & SURFACE PURIFICATION TECHNOLOGY Unlike other air purifiers, Viro Tech Mini does more than simply filter the air in your space. Incorporating technology like photo catalytic oxidation, high level negative ionisation, scalable purification and electrostatic filtration allows the air purification system to provide tangible benefits to your environment. Destroying pollution from the air, embedded in walls, ceilings, floors, carpets, furniture, etc. Reducing or eliminating odours such as cigarette smoke, mildew, food, etc Contributing to the sanitization of all surfaces. The whisper quiet five-speed fan disguises the power encapsulated in the advanced air purification system. Having the air purifier in your space will not only improve the quality of air but most importantly it will improve the quality of life.
