Do Air Purifiers kill Bacteria and Germs?

Updated: Apr 9


We have always heard about purifying the air to keep out the airborne particles such as dust, dirt and smells. But is the air considered clean after purifying? The air contains not only the pollutants but also bacteria and germs that you can’t see with your naked eyes. Using an air purifier does not necessarily eliminate bacteria, viruses, fungus and spores. In fact, after using an air purifier, the air can still contain bacteria, viruses, fungus and spores that can infect us. Disinfecting the air will help us stay safe from these bacteria and irritants that are harmful to our health. Let’s understand the difference between purifying and disinfecting the air and how they work.



How do air purifiers work?

Air purifiers reduce airborne particles including dust, smoke, pollen, and dander from the air by forcing air through a filtration system; while filtration systems are the most common, carbon, UV, and ionizers are used. Air purifiers lower irritation by reducing particles, but not necessarily germs; germs will remain in the air and on surfaces, even as the airborne particles are removed.


The effectiveness of air purifiers in removing particles largely dependent on the quality of air filter of the machine, the location of where you place the air purifier as well as airflow and duration of the operation.



What is disinfection? It is a process to eliminate bacteria, viruses, fungus and spores. When it comes to disinfection, we often think about the surface and neglect the fact that there are also bacteria and germs in the air. Aerial Disinfection

Aerial disinfection introduces a spray, mist, or fog into a room to kill the airborne germs. High-quality aerial disinfection products can kill bacteria, viruses, fungus, and spores, contain no harmful chemicals, non-irritant, and have been 3rd party tested to prove efficacy.


An aerial disinfection machine is designed to produce a mist that can fill a room; the mist should be dry enough to allow it to stay airborne and kill the bacteria and germs found in the air. The machines that generate the disinfecting dry-mist convert the liquid disinfectant into the mist and propel the mist throughout an area to disinfect it.


Sprays for surface disinfection or any wet products are not effective against airborne germs - the wet nature of these products will not stay airborne to kill the microscope germs we might breathe.



How to choose an effective aerial disinfection product? The critical factors for the effectiveness of aerial disinfection products and machines include:

#1 Safety - is the product safe for inhalation, to touch the skin, and won't cause any irritation to the eyes

#2 Proven effectiveness - does the product able to kill bacteria, viruses, fungus, and spores found in the air?

#3 The machine - handheld spraying is random and not proven effective; always use a machine that produces a dry-mist with features that ensure the mist will fill the room or area.


When using BioCair disinfecting machines with BC-65 Air purifying solution, dry mist that generated from the machines are able to eliminate bacteria, viruses, fungus and spores that are found in the air and on surfaces, keeping your air disinfected and pathogen-free. All BioCair products are tested and proven to be non-toxic, non-irritant to eyes and skin and safe for use around children.
