In the past 20 years, UV technology has been a leader in disinfection, since people can get a full sterilization effect without harmful chemicals added from it. In 2019, there have been many new developments in UV disinfection technology, concerning component upgrades and disinfection applications.

In 2019, a germicidal LED supplier from CA, USA announced they had got important progress on UVC emitters. Their latest UVC emitter has a 99.999% killing rate of methicillin-resistant staphylococcus aureus (MRSA) from a distance of 1m to the targeted surface, covering about 1㎡in area, and the process only took less than 1 minute. MRSA is a dangerous super germ that is resistant to penicillin and amoxicillin (among other common antibiotics). This experiment was done by a third-party laboratory. This technological innovation means that it has greatly improved the UVC killing efficiency and practicality of super bacteria, which will make UVC more widely used in medical health and food safety.

According to news from the world's major UVC LED suppliers, in the second half of 2019, the production and supply of UVC LEDs have significantly improved, and this development has reduced the application costs of UVC LEDs. Low-cost, safe, compact and efficient features also attract more small appliances suppliers to invest in the innovation and development of UVC LED disinfection products. For example, some innovators have applied UVC LEDs to robots and drones, combined UVC tech with popular technologies to develop future disinfection products with special effects.

In addition to disinfection robots and drones, many innovative UV home sterilizers are developed for general consumers, like the UV bottle sterilizer and dryer, which is lighter and with more compact size than traditional models. Using the latest UVC LEDs as sterilization elements, this electric baby steriliser has reduced the size of the device by more than 50%. There are also many new UV disinfection equipment such as UV cell phone sanitizer and charger, more compact portable UV disinfection lamp, etc. It is believed that in 2020, consumers can see more useful and safe new household disinfection equipment on the market.
