Seoul Viosys will hold a campaign of pilot installation for new Violeds technology solution by August 31st, 2020 focusing on public facilities such as offices, shopping centers, and airport in the world as a part of anti-coronavirus. Inquiries and applications are available on its website (www.seoulviosys.com/en/) and Seoul Viosys’ partners will support additional requests after finishing the first campaign period.
Seoul Viosys provides major manufacturer of air conditioners with optimized UV LED solutions based on successful testing results of 99.9% sterilization of the new coronavirus in 30 seconds by the research group of Korea University. In June, a global air conditioner manufacturer that produces 40 million per year has adopted Violeds technology for its thirty models.
Through the results of testing by Guangzhou Institute of Microbiology in China (CGMT), Gree demonstrates that its new “Fresh Air” air conditioner with Violeds UV LED technology has the performance to sterilize 99.15% of viruses and bacteria, 98% of enteroviruses such as EV71 and H1N1, and 99% of staphylococcus albus bacteria. In addition, it has been proven to sterilize 90% of various harmful viruses in air in 2 hours when using their air conditioners.
Violeds technology has been adopted not only by the Chinese AC manufacturer Gree, but also by a leading in-duct air treatment supplier in the U.S. Seoul Viosys will provide its technology for air conditioners of a leading electronics brand.
Conventional air conditioners typically draw outside air into the AC unit, and discharge that air back into the interior after cooling and filtering, where it is continuously recirculated. This recirculation of indoor air may cause a higher risk of infection through aerosol transmission when viruses are present. The amount of dust and moisture on the cooling filter can also transmit harmful viruses. Conventional filter in air purification system can filter out general droplets or fine dust more than 0.3μm but the viruses such as new coronavirus and SARS virus itself as small as 0.1μm can pass through the HEPA filters as it is.
“As a result of successful production approval to supply Violeds products and expanding customer demand, Violeds UV LEDs have clearly been recognized as essential technology for HVAC (Heating, Ventilation, and Air Conditioning) systems. We believe that our new Violeds technology solution for disinfection of air conditioning and heating systems helps to eliminate viruses in air and protect people from COVID-19 pandemic,” said a representative of Seoul Viosys.

Bleeding gums? Don't ignore the warning signs – the first stage of gum disease can be reversed26.10.2026 12:28:00 EET | Press release
Gums bleeding when brushing can happen to any of us, and it is easy to ignore. But blood in the sink is a sign that something is not right with your mouth. Bleeding gums often indicate gingivitis, the earliest and most common form of gum disease. The good news: gingivitis can be reversed with proper oral hygiene. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20261022835650/en/ Oral-B iO Left untreated, gingivitis can progress into periodontitis, a more severe stage of gum disease that can only be managed, not reversed, and can lead to losing teeth over time. Healthy gums matter beyond the mouth, too. Oral health and systemic health are deeply interconnected, with inflammation and bacteria from oral diseases contributing to conditions such as heart disease, diabetes and dementia. "Gums bleeding when brushing can happen to any of us. When they do, it shouldn't be ignored," said Eva Castro Perea, who holds a degree in dentistry
Merz Therapeutics Presents New Phase 2 PaiNT Data in Peripheral Neuropathic Pain at IASP 202626.10.2026 09:00:00 EET | Press release
Merz Therapeutics, a leading player in neurology-focused specialty pharma, today announced the presentation of new clinical and translational research in peripheral neuropathic pain (PNP) at the International Association for the Study of Pain (IASP) 2026 World Congress in Bangkok, Thailand, taking place from 26 to 30 October. The research spans new Phase 2 findings on incobotulinumtoxinA in postherpetic neuralgia (PHN) and post-surgical/post-traumatic neuropathic pain (PS/PTNP), as well as preclinical studies exploring potential biological mechanisms involved in effects of incobotulinumtoxinA on PNP models, highlighting Merz Therapeutics’ growing presence in neuropathic pain. In the PHN population of the Phase 2 PaiNT trial, results over 20 weeks favored incobotulinumtoxinA versus placebo treatment. In an exploratory analysis of average daily pain (ADP) intensity, the greatest difference between treatment groups was observed at Week 6 (adjusted mean difference, −1.14 points; p=0.0488).
