The rising level of air pollution and biological contamination are significant factors that can ruin indoor air quality. The air quality indoors has a substantial impact on you and your family. By maintaining indoor air quality at a safe level, you can reduce the potential transmission of pathogens, alleviate allergy symptoms, and improve respiratory conditions.
Do you know that indoor air is typically 5-10 times more polluted than outdoor air? Hard to believe, isn't it? A primary reason for this is that the circulation of air indoors is very low, which, in turn, leads to the accumulation of pollutants.
Fortunately, you can avoid such issues by using a combination of filtered ventilation and an air purifier. However, before procuring a solution, it is also essential to consider the technology used in these machines, with HEPA and MESP being the two most widely used air filtration technologies.
This blog will help you learn more about these technologies and guide you in choosing the right one to keep your indoor air clean and safe.
Though MESP, or Micro Electrostatic Precipitator, and HEPA, or High Efficiency Particulate Air, both help in air filtration, they differ in terms of their efficiency and mechanism. Let’s get to know these two air purification technologies in detail.
HEPA is a common type of filter that you can find in an air purifier for the home. It is designed to capture around 99.97 per cent of 0.3-micron particles and is generally made of materials that combine polypropylene and fibreglass. This air filter works on impaction, interception, and diffusion mechanisms.
Although HEPA filters can trap different particles, they cannot kill microorganisms. Thus, when using an air purifier with a HEPA filter, it is essential to replace the filter regularly to maintain its effectiveness.
You should keep in mind that the viruses trapped in the HEPA filter are active, which can lead to risks like:
The viruses can re-contaminate if the filter is not cleaned regularly using appropriate methods.
Users of the air purifier may become infected with viruses while replacing the filter.
This cutting-edge air filtration technology is highly efficient in capturing and eliminating various airborne pollutants, including smoke, mould, dust, bacteria, pollen, and more. In this air filtration system, airborne particles are electrically charged using an electrostatic field and then trapped in a honeycomb-shaped filter.
These filters are also quite effective in sterilisation, as the presence of a high-voltage electrostatic field (more than 10 kv) kills bacteria and viruses by destroying their protein shells. In fact, MESP has a 99.99 per cent sterilisation rate and can kill the SARS-Cov-2 pathogen. Hence, while looking for the best air purifier for home, prefer choosing the one that uses an MESP filtration mechanism.

According to the table above, it can be observed that HEPA filters are effective in capturing particles. However, using an air purifier for home with MESP technology can be a better option, allowing you to enjoy the benefits of both air purification and sterilisation.
As discussed, the MESP air purifier eliminates viruses using a high-voltage electrostatic field. Continue reading to understand the entire process.
Charging Airborne Harmful Particles
When indoor air moves through the MESP air purifier, harmful particles present in the air get electrically charged. Negatively charged particles move towards the positive plate of MESP due to the strong electric field.
Electrostatic Field
While moving through the system, charged airborne particles are exposed to an electric field, which damages the virus’s genetic material and protein to neutralise them. Next, the pollutants gradually become carbonised and get eliminated. The field can trap nearly 100 percent of biological aerosols, allergens, PM2.5, pollen, and other harmful pollutants.
Trapping Viruses
Once the particles are neutralised, they are trapped in the filter inside the system, ensuring all pollutants are removed from your indoor air.
This sophisticated process not only captures harmful microorganisms but also sterilises them. And, for that reason, MESP air purifiers are more effective than HEPA systems.
