Aerial Disinfection: Why Disinfected Air Is Safer Than Purified Air


As seen in most air purifiers' advertisements, 'clean air' is often interpreted as purified air with no air pollutants; hence it is safe to breathe. However, such clean air does not equate to safe air. Similar to invisible air pollutants, there are microscopic bacteria and germs present in the air too.

An air purifier can lower the number of airborne particles, but that does not disinfect the air. Purified air may still contain bacteria, viruses, fungus and spores. These germs are microscopic and can pass through most filters in the air purifier.


Aerial disinfection

Aerial disinfection eliminates bacteria and germs in the air and can be executed via a spray, mist, or fog. Efficacy of the methods varied differently. Disinfectant products that can kill highly resistant bacteria and germs are generally harmful to human health. At the same time, there are products claimed to be effective against certain bacteria and germs but are not proven or tested by any independent *GLP accredited testing laboratories. Hence, to look out for high-quality aerial disinfection products, they must fulfil the following requirements:

1. Able to kill bacteria, viruses, fungus, and spores

2. Non-toxic, non-harmful

3. Tested by independent GLP testing laboratories to prove efficacy

An aerial disinfection machine can produce a mist to fill a room. It converts liquid disinfectant into mist and propels it throughout an area to eliminate bacteria and germs. The mist should be dry enough to allow it to stay airborne to kill the bacteria and viruses in the air. Once the mist lands, it will also eliminate the surface bacteria and germs.


Selecting a Quality Aerial Disinfection Product

Many products in the market claim to kill airborne bacteria and viruses, but to choose a quality aerial disinfection product, we must consider the technology behind the product. Always review the manufacturer's proven effectiveness, safety and reliability. A good quality aerial disinfection product should validate through independent testing.

1. Effectiveness - Reduction of particles (size and rate) and or kill rate for germs, kill time, and ability to kill bacteria, virus, fungus, and spores

2. Safety - Safety is the crucial component of a disinfectant. Using disinfection solutions and products that contain toxic and irritants chemicals poses a safety hazard. Avoid toxic chemicals that are dangerous to inhale and leave toxic residue.

3. Validated - Testings performed by independent, accredited laboratories

4. Trusted - Ensure the brand has a proven record

*Good Laboratory Practice (GLP) is a quality system of management controls for research laboratories and organizations to ensure the uniformity, consistency, reliability, reproducibility, quality, and integrity of products in development for human or animal health (including pharmaceuticals) through non-clinical safety tests; from physio-chemical properties through acute to chronic toxicity tests.
