Effects of hydroxyl radicals contained in water

The many effects of hydroxyl radicals contained in water include the inhibition of the activity of viruses, bacteria, and allergens, the reduction of odour intensity, and moisturisation. With effects verified through experiments by universities and research institutes, the technology of hydroxyl radicals contained in water is drawing attention for its contribution to more comfortable living environments.
