[Asia Economy Reporter Kim Heeyoon] #At lunchtime, as people crowded into the building elevator, a machine installed to the left of the door displayed the real-time air quality status inside the space. Due to the influence of outdoor air, the ultrafine dust level was marked as poor, and with the sudden increase in passengers, the carbon dioxide and formaldehyde levels rose, triggering poor status messages for both. This information was immediately sent to the management office via alert text message.

Signal analysis specialist company Envinode has responded to the ongoing resurgence of COVID-19 by simultaneously introducing virus detection and sterilization devices to control viruses in indoor spaces and help prevent the spread of COVID-19.

On the 15th, at an office in Pangyo, Seongnam-si, Gyeonggi-do, Envinode CEO Kim Bangryong explained, "With the recent spread of COVID-19 mainly in multi-use facilities, we launched the virus detection device 'BioCloud' and the sterilization device 'EnviAir Plasma' to ensure safety in indoor spaces."

Envinode had previously succeeded in developing an intelligent air threat awareness system in 2019 that detects and analyzes 29 types of toxic industrial gases including chemical, biological, radiological, nuclear (CBRN) agents, fine dust, and air quality gases in real time. Based on air quality detection technology, the company emphasized that EnviAir Plasma, which combines bipolar ions and UV-C LED, maximizes coronavirus sterilization effects.

Detecting Dust and Pollutants Indoors, ‘Automatic Sterilization’ with Ions and Ultraviolet Light

EnviAir is equipped with the function to neutralize and decompose dust and pollutants in the air through a large amount of bipolar ions and ultraviolet LED. It is an air circulation sterilization device that effectively reduces bacteria and viruses while simultaneously decreasing total volatile organic compounds (TVOC). CEO Kim said, "Besides sterilization, this device measures air quality by detecting temperature, humidity, ultrafine dust, harmful chemicals, carbon dioxide, and formaldehyde through a smart air quality sensor, providing information on an LCD screen for real-time monitoring."

According to the Korea Disease Control and Prevention Agency, coronavirus infection occurs through direct contact, droplets, and fine airborne particles. Therefore, measuring the increase or decrease of ultrafine dust (PM2.5) and harmful substances can serve as an indicator to verify the safety of a space. Additionally, EnviAir is designed to operate fully automatically by recognizing the air quality status and motion sensor data. CEO Kim emphasized, "Air quality information from the installation site can be stored in the cloud via IoT. Furthermore, remote monitoring of each device’s operational status and real-time alert text messages to managers enable prompt management and response."

Initially focusing on the possibility of COVID-19 spreading in public facilities such as buses and elevators, CEO Kim stated that the product was developed to simultaneously measure indoor air quality and perform air purification and sterilization for rapid virus sterilization. EnviAir purifies indoor spaces ranging from 9 to 33 cubic meters within minutes to tens of minutes, providing a safe indoor environment from the COVID shock, he added.

Real-Time Detection and Analysis Device for Airborne Pathogens, Preemptive Blocking of Risk Factors

The virus detection device BioCloud, developed alongside the sterilization device, is a real-time analysis device designed to detect airborne pathogens. It promotes air circulation and continuously samples pathogens such as viruses, bacteria, and mold by monitoring air quality in real time. CEO Kim said about BioCloud, "By combining a proprietary detection chamber and air sampling process, it detects and analyzes viruses on-site, eliminating the need to transport samples to separate laboratories. This quickly prevents indiscriminate spread of risk factors."

BioCloud detects viruses within 6 minutes in a 100㎡ indoor space and within 15 minutes in a 230㎡ space through an air sampling pump and air circulation fan. Additionally, it sends immediate email or text message alerts to managers or responsible personnel via Bluetooth and WiFi communication upon detecting coronavirus, facilitating rapid site closure and disinfection. CEO Kim added that event information from BioCloud is stored on a cloud server for utilization. According to Envinode officials, inquiries for installation are currently increasing mainly from schools, childcare facilities, nursing homes, military barracks, medical facilities, large restaurants, religious facilities, childcare centers, financial institutions, insurance companies, call centers, and large corporate offices where many people are gathered in enclosed spaces.

CEO Kim emphasized, "EnviAir functions as a solution to prevent cross-infection by deploying multiple units in small indoor spaces, while BioCloud will provide answers to questions about whether the space you are currently in is truly safe, especially at a time when tracking confirmed cases is difficult."
