UV-C is a frequency that ranges from 254 to 265 nanometer ultraviolet light, which is usually isolated outside the Earth by the atmosphere. Experiments have proven that this ultraviolet light can effectively destroy microbial DNA, bacteria, viruses, dust mites and other microorganisms; as a result, this helps achieves maximum air purification. UV-C does not leave any residue after sterilization, which is beneficial to the environment.
An ultrasonic cleaning is a process that usesv ultrasound (usually from 20–400 kHz) and an appropriate cleaning solvent (sometimes ordinary tap water) to clean items. The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned and the type of soiling present enhances the effect.
