Happy Day's sterilizing effect Happy Day has more powerful ultraviolet sterilizing effects than sunlight so it sterilizes bacteria in every corner of a house by 99.9% within a few seconds. Happy Day is a highly advanced home sterilizer which can almost perfectly sterilize E. coli which is a cause for food poisoning, staphylococcus aureus, infectious trichophyton, and house dustimte which is a cause for asthma and atopy.
Sterilize and remove dusts at a time Steam cleaning and simple medicinal sterilization can't perfectly kill the bacteria living in a house because the dead bodies and excrements of house dustmite, which remain after it is sterilized, are the major allergen of atopy and asthma. Happy Day has made up for the weakness of general sterilization so it sterilizes and at the same time, removes dusts and the dead bodies and excrement of house dustmite at a time. It is the world's first home sterilizing cleaner.
Distinguished portability Happy Day includes a rechargeable battery of high capacity so it can be easily used not only at home, but also in a vehicle and a warehouse where no power supply is available. It is also easily applied during a trip in a tent or a lodging facility where sterilization is necessary.
Highly advanced safe design The excellent safe design of Happy Day is the craftsmanship of BIZTECH that thinks customers. ON/OFF double click function which is to prevent any malfunction by babies, ultraviolet-type floor sensing, a safety sensor, a buzzer which makes it possible to easily check the operating status, and a translucent bumper are the differentiated safety design of Happy Day's own. It is not a medicinal type so it can be safely used for sterilizing kids' beds or dolls.
Promoting of photocatalyst VOC, which is an allergen of sick house syndrome, is emitted a lot in a dark corner so photocatalytic construction is not effective in a dark place without sunlight. In this case, Happy Day, which is shed on the dark place where photocatalyst is applied, can promote to dissolve harmful gases (pormaldehyde).
