Our Hygiene Active system is a combination of technologies which protect your food from coming into contact with harmful bacteria. The combination of a silver filter, which produces silver ions, as well water mist and blue LED light forms an anti-bacterial cleanser called ‘Hydroxy Radical’, which naturally occurs in the troposphere. This natural effect is produced inside a Panasonic refrigerator, eliminating 99.9999% of harmful bacteria. The effect has been tested and certified by SLG, a renowned independent test laboratory.
