uHoo Virus Index: here's how to keep your space virus-free
With data from the uHoo Virus Index technology, the new wireless PPP air purifier and the uHoo IAQ sensor integrated into the Control Free platform, it is now possible to limit the presence of COVID-19 and other airborne viruses indoors. Here comes a ready solution to keep your home and office virus-free!
The pandemic and imposed quarantine forced people to spend more time indoors, where the air quality often leaves much to be desired. In addition to the high risk of exposure to common pollution emissions from daily activities, such as cooking and cleaning, dust and humidity, we are also under threat of inhaling biological contaminants, including bacteria and viruses, which have been proven to spread through centralized AC and ventilation systems when airborne.
The link between indoor Air Quality and viral activity
According to some news articles we shared in our social media channels (Facebook, LinkedIn), there is a strong evidence that positively correlates certain air quality readings–such as humidity and carbon dioxide levels–with viral presence in the air. Additionally, uHoo, the IAQ sensor brand provided by Elevant-Garde, has published a white paper that consolidated research from various governments, universities and international medical and environmental journals that explain the relationship between air quality and COVID-19 death rates.
As the uHoo's report states, research published by the American Society of Microbiology showed that SARS-COV surrogate viruses–a coronavirus genetically very close to SARS-CoV2/COVID-19–survive longer and can become airborne when specific combinations of temperature and humidity are reached. The air we breathe indoors can also be a factor for viruses. Particulate Matter, also known as “Particle Pollution”, is a complex mix of small particles and liquid droplets. Particulate Matter at 2.5 microns is small enough to stay suspended in the air for viruses to latch onto, thus making the viruses airborne. A study published in the journal of Genome Biology showed that PM2.5 accommodates rich microbial communities that can heighten health risks. Scientists from Harvard University also reported that long-term exposure to PM2.5 increased chance of death amongst COVID-19 patients.
Busy streets and combustion sources that create nitrogen dioxide also contribute to the deterioration of air quality in your homes and workplaces. Inside buildings, ambient infiltration of nitrogen dioxide occurs due to the building's structural imperfections which can be exacerbated by poorly designed or poorly maintained ventilation systems. Exposure to raised levels of nitrogen dioxide inflames the lining of the lungs, which may subsequently reduce our immunity to fight COVID-19. Aside from nitrogen dioxide, continuous exposure to high levels of carbon dioxide can also cause lung-inflammation and put vulnerable people at higher risks. Having sufficient ventilation not only dissipates high levels of CO2 inside your home/workplace but also flushes out particles that may have viruses latched onto them.
What is the "uHoo Virus Index"?
The recently launched "uHoo Virus Index" is a patent-pending technology that focuses on analyzing air quality data (monitored by uHoo, IAQ sensors) as a whole. It assesses the risk of viral activity within homes or workplaces, as well as the effects of the air quality on the general health and immune system of people inside the monitored spaces.
The "uHoo Virus Index", a 10-points scale, is divided into four air quality levels: Good (1-3), Mild (4-6), Bad (7-8) and Severe (9-10):
The white paper titled "Using Indoor Air Quality Data to Create the uHoo Virus Index" explains how the Virus Index was created and can be found here.
uHoo monitors nine different indoor air parameters–temperature, relative humidity, carbon dioxide, PM2.5, carbon monoxide, nitrogen dioxide, ozone, volatile organic compounds (VOCs) and air pressure–and provides real-time data, alerts, insights, and recommendations.
Integration with air purifiers
To make use of the uHoo Virus Index technology and real-time data measured by uHoo, Elevant-Garde has integrated the uHoo IAQ sensor as well as PPP air purifiers into the Control Free platform. IAQ data recorded and analyzed by uHoo can be viewed with the Control Free web dashboard and processed for further automations.
The new air purifier from the awarded Green Breeze PPP brand features Wi-Fi function, which makes it easy to be integrated into Control Free platform for automation solutions. Both purifiers and A/C units can be automated based on air quality readings from the uHoo sensors as well as the uHoo Virus Index air. Now available at Elevant-Garde, the PPP-402-01 is equipped with a filter of the highest-level (400 KV Blue Filter) developed specifically to remove and kill airborne viruses and bacteria in the air (including H1N1, EV71, measles Virus, MERS).
