You may have seen the name in passing, but what exactly is a HEPA filter, and how does it affect the air around you? Given how the world is still dealing with the Covid-19 pandemic, the time to learn more about these filters is now. This is mostly down to the fact that HEPA filters come in different grades and are suitable for different scenarios. It’s important to be familiar with them so you can pick the right one for your air purifier in Singapore to maximise its efficiency.

What is a HEPA Filter?

A high-efficiency particulate air (HEPA) filter is a device that is designed to remove particles from the surrounding air. These filters are normally used by air filtration appliances like air purifiers,  air cleaners, and air ionisers in Singapore — after all, these appliances are built to remove various particles and pollutants from the air in your home, workplace, or even your car.

In short, HEPA filters help remove tiny particles, mould, pollen, bacteria, viruses, and other pollutants from the air. While larger particles stick to the filter, they also keep smaller particles from passing through. HEPA filters can generally trap particles as small as 0.3 microns. HEPA filters are particularly effective when used with an air cleaner in Singapore, as these filters can remove up to 99.97% of particles from the air.

Today, most HEPA filters are made from a mixture of interlaced glass fibres. Additionally, particles captured are done so in one of four ways — direct impacting, interception, diffusion, or sieving. There are also different grades of HEPA filters that cater to different scenarios.

HEPA Filter Grades

HEPA filter grades range from H10 to H14; the higher the grade, the higher the performance. H10 to H12 HEPA filters are commonly known as “true HEPA” filters. These filters trap fewer particles than their higher-grade counterparts. H13 and H14 HEPA filters are known as “medical grade” filters and these filter 99.95% and 99.995% of all particles down to 0.3 microns respectively.

H13 and H14 HEPA filters are widely used in industries that require very clean environments, such as medical or electronics manufacturing facilities as these filters have the highest particulate retention rate and are therefore more suited for the air purifier in Singapore used in those settings.

Higher-grade HEPA filters are better in filtering the air around you. Why then, do folks still opt for lower grade filters instead? This mostly boils down to cost, as higher-grade HEPA filters are often significantly more expensive than their lower-grade counterparts. This is why only professional settings like hospitals, operating theatres, and the aforementioned manufacturing facilities use higher-grade HEPA filters, while homes often use the more affordable H10 to H12 HEPA filter-fitted air ionizer in Singapore instead. However, with the advancement of filtration technology in recent years, higher grade HEPA filters are more accessible to regular households, to the point where H14 HEPA filters are starting to be advertised to families as well.
