Daikin's Streamer Technology revolutionizes air purification.
This website provides information on the results of demonstration experiments conducted with various research institutions.
Patented Streamer Discharge Technology
What is the Streamer technology?
The Streamer technology developed by Daikin Industries is an epoch-making air purification technology that has succeeded in stably generating "high-speed electrons,“ which had been considered difficult up to that time.
- About Streamer Technology
The Streamer discharge is a type of plasma discharge that generates "high-speed electrons", which have high oxidative decomposition power in a three-dimensional and wide range, so the oxidative decomposition power is 1,000 times or more compared to general plasma discharge (glow discharge).
With this technology, high-speed electrons that combine with air components have a strong oxidative decomposition power, so they continuously act on odors, bacteria, and indoor pollutants such as formaldehyde.
So far, we have demonstrated in collaboration with universities and public research institutes that it acts on harmful substances such as influenza virus, norovirus, toxins and bacteria that cause food poisoning.
