Here’s how air purifiers can help cut down on the risk of indoor COVID-19 transmission.
After almost two years of lockdowns, social distancing, mask wearing and quarantining, it felt like we were finally starting to see the light at the end of the COVID-19 tunnel. But infection rates in many cities around the world are on the rise. People are adjusting their holiday plans due to the Omicron variant, and transmission is back to being a major fear.
While research into the virus is always evolving, it’s become clear that indoor spaces are hotspots for COVID infections. “Airborne transmission is dominant,” says Harvard environmental epidemiologist Joseph Allen, and in closed spaces with poor ventilation, the likelihood of contracting the virus spikes. The fact that the virus can spread via droplets in the air means that we must be highly vigilant about what exactly we’re breathing in on a daily basis.
The good news is that by improving indoor air quality, you can significantly reduce the risk of COVID-19 transmission, as well as ease allergy symptoms, sleep better, and boost overall respiratory health. The key is finding the right method to eliminate airborne contaminants in your home or office.
What are airborne contaminants?
Although they aren’t visible to the naked eye, there are indeed pollutants present in the air we breathe. Viruses, bacteria, mold spores, allergens like pet dander and pollen, and other contaminants remain suspended in the air, in the form of tiny particles.
The impact of these particles can vary from mild allergy symptoms to much more significant medical conditions. Mold spores can trigger respiratory issues, and bacterias and viruses spread via the air can cause illnesses (including COVID-19.)
The situation is critical when you consider that we spend around 90% of our time indoors. There are a number of immediate steps you can take to make the air you breathe safer. Whenever you can, leave a door or window open. You should also consider exploring indoor air quality solutions, like indoor air purifiers, which remove harmful airborne contaminants.
Indoor spaces and COVID-19
In line with scientific consensus, researchers from the University of Cambridge confirmed that the overwhelming majority of COVID-19 cases are spread through indoor transmission. You are far more likely to contract the virus while in a poorly ventilated indoor space than outside.
According to the COVID Airborne Transmission Estimator, spending time indoors with someone who is infected is extremely risky. A report from El Pais found that if six people spend four hours together in a poorly ventilated room, without wearing masks, five will become infected. Shockingly, even if everyone does wear masks, the odds are that four people will become infected.
When you’re indoors, especially in a space with poor ventilation, the air everyone is breathing re-circulates throughout the room. If someone with COVID-19 coughs, they will unwittingly expel pathogen-laced droplets which spread throughout the space and remain suspended in the air. Without proper ventilation, the infected particles have nowhere to go.
Indoor air quality testing
How good are the ventilation levels in your home? If you have no idea, you’re not alone. Many people simply have no clue if their home is poorly or well ventilated. To gauge the levels of ventilation in your home, you can use an indoor air quality testing device.
Particle counting meters, which monitor particulate matter (PM) concentrations in the air, can give you a snapshot of your current indoor air quality situation.
The safest option is to meet with others outside, where an infected person’s airborne droplets will be naturally swept away by air currents. But that isn’t always possible, especially in the frosty winter months.
Fortunately, there are a variety of indoor air quality products you can consider purchasing to help manage the risk of COVID-19 indoors.
How an indoor air purifier can help with COVID-19
The EPA says that increasing ventilation with outdoor air and air filtration systems, like purifiers, can help mitigate COVID-19 transmission risk, in addition to following guidelines around mask-wearing and social distancing.
Indoor air purifiers remove airborne pollutants using a variety of methods. Some utilize HEPA and carbon-activated filters that catch pollutants as they pass through. Electrostatic fields and ionization that draw in airborne contaminants are featured in other systems.
Tadiran’s Air Care O2 leverages proprietary technology to transform existing H2O (water) molecules in the air to pathogen-zapping hydrogen peroxide, which actively cleanses and purifies the air.
Air Care O2’s unique air purifying technology has been scientifically proven to reduce COVID-19 in a test held by Innovative Bioanalysis, in a one cubic meter test chamber. After only 90 minutes 0.002% of the COVID-19 virus was detected.
