Purified Air Is Not Always Bacteria-Free: The Dirty Truth Behind The Air You Breathe


The air we breathe is loaded with thousands of bacteria—in fact, our indoor air is actually much more contaminated than outdoor air, no matter how clean it may appear to be. These tiny living things cannot be seen by the naked eye, and while most of them are generally harmless, they can sometimes sneak past our defenses and cause us to fall seriously ill. So how do germs get into our air? In this article, we take a look at how bacteria and viruses can live in indoor environments, and how we can keep the air safe and healthy at home.


Purified air is not bacteria-free air.


Let’s clear things up once and for all: purified air is not always free from bacteria and germs. Just like a surface, the air can appear clean and dirt-free but still harbour high levels of invisible bacteria. So what can we do to reduce the spread indoors?


An air purifier is one of the best ways to improve indoor air quality – air purifiers are known to ‘clean’ the air by filtering out all kinds of airborne particles commonly found in the home, including dust, smoke, pollen and pet dander. However, it’s not enough to trap harmful bacteria as most of these microscopic pathogens are so small that they simply pass through the filters. Hence, germs will remain in the air and on surfaces, even as airborne particles are removed.


Where do airborne germs come from?


This begs the question of how bacteria and germs enter our homes. This is known as airborne transmission, and it’s commonly transmitted when an infected individual talks, coughs or sneezes in an indoor space. These micro-sized aerosols can travel throughout the room and stay suspended in the air for hours, even after a person has left the room. 


Some of these droplets may also carry illness-causing pathogens, which can lead to severe respiratory infections when inhaled by another person. This is especially true if you were to spend more time indoors than outdoors, particularly in enclosed environments with inadequate ventilation. In such cases, the risk of transmission is likely to be higher as there’s limited air movement to disperse the particles.


Although less likely, the spread of germs and viruses can also sometimes occur through direct contact with contaminated surfaces. For instance, when other members in the household bring back germs from the outside, be it from school or work, it can then be spread by touching common surface areas in the home. This heightened exposure can cause the rest of your family to get infected as a result, which is why it’s important to protect you and your loved ones from both surface and airborne threats.


How can we avoid airborne infections at home with BioCair?


While we cannot avoid germs altogether, disinfecting the air regularly can help to lessen the chances of airborne transmission. And no—you don’t need an air purifier for this. 


A better bet is to use the BioCair air disinfectant machine, which is specially designed to kill 99.999% of airborne germs such as bacteria, viruses, fungus and spores. Unlike air purifiers, an air disinfectant machine works by converting the liquid into a lightweight disinfectant mist that propels throughout a room, killing off any traces of pathogens found in the air. This helps to prevent the spread of potential infections, all while improving indoor air quality for a safer and healthier living space. That’s not all; it can also help to eliminate surface germs once it has settled onto nearby surroundings, providing you with an additional layer of protection to safeguard against unwanted nasties.


Your home is meant to be a safe place; bacteria and germs don’t belong there. With BioCair, you can now breathe non-toxic and bacteria-free air without any worry.
