Busting Myths: How Do High-Efficiency Particulate Air Filters Work?

The modern world is more aware than ever of the importance of clean air. Our health, comfort, and overall well-being depend on the quality of the air we breathe. Air purifiers have become a popular solution for many who wish to improve their indoor air quality. One type of air purifier that stands out is the HEPA Air Filters. But what makes them unique? And how do they work? In this blog post, we will dive deep into understanding HEPA purifiers and debunk some common myths surrounding them.

The Magic of HEPA: A Closer Look

High-efficiency particulate Air (HEPA) filters are known for their ability to capture tiny particles from the air. Unlike regular filters that might miss out on smaller contaminants, true HEPA filters can capture up to 99.97% of airborne particles as small as 0.3 microns. These particles include dust pollen, airborne particles, and even some bacteria and viruses.

The magic lies in the dense mesh of the filter. Larger particles are captured via interception as they travel through the filter and come in contact with fibres. Meanwhile, the smaller particles, such as dust particles, are trapped by diffusion, where they collide with gas molecules and slow down, eventually getting caught in the HEPA fibres.

A HEPA (High-Efficiency Particulate Air) filter is a class apart from the standard air filters you might typically use in your home. Unlike conventional filters, HEPA filters boast a unique construction, characterized by a pleated design that gives them a noticeable thickness. These pleats form a thick mat of fibres that are organized in a seemingly random manner. This dense and random layout of fibres is instrumental in ensuring that the filter captures a wide array of particle sizes.

How HEPA Filter Works?

As the air flows through a HEPA filter, three primary mechanisms work in tandem to trap particles: diffusion, interception, and impaction. Diffusion involves the smallest particles, which are bombarded and hindered by gas molecules, causing them to stray from their path and eventually adhere to the fibres. Interception takes place when particles, following their airstream, come within one particle’s radius of a fibre and get ensnared. Lastly, impaction is when larger particles are unable to avoid fibres any longer due to their size and inertia, leading them to embed directly into the fibres.

Given that HEPA filters are designed to trap even the minutest of particles, their longevity can be a concern, especially in environments with high particulate concentrations. One effective strategy to extend their lifespan is the integration of a pre-filter. A pre-filter acts as the first line of defence, capturing larger particles and ensuring only the finer particles reach the HEPA filter. At ISO-Aire, we recognize the importance of this dual filtration approach. That’s why all our commercial air purifier units come equipped with MERV-8 pre-filters. This not only assures more effective air purification but also substantially elongates the operational life of the HEPA filters.

The Extra Layer: Active Carbon Filters

To step up the purification process, many of the best air purifiers on the market integrate active carbon filters. These filters are experts at trapping odours, smoke, and volatile organic compounds (VOCs). The activated carbon inside these filters has a vast surface area that effectively captures these unwanted elements, ensuring that you are not just breathing air free of dust and pollen but also odours and harmful chemicals.

Myths Busted: The Truth about Replacing the Filter

A common misconception is that once you have invested in an air purifier, there’s no need for maintenance. However, for the device to remain highly efficient, replacing the filter periodically is crucial. Over time, filters can become clogged, reducing their effectiveness. Regularly changing them ensures that your indoor air quality remains optimal, whether you place them in the bedroom, living room, or any other space.

Finding the Right Fit: Features to Consider

When considering an air purifier, think about its capacity. Some devices are better suited for larger rooms, while others are perfect for smaller spaces. Features like remote control can offer convenience, allowing you to adjust settings from the comfort of your couch. Another crucial aspect to consider is the noise level. Many people prefer devices that operate silently, especially if they are for the bedroom. Opting for units with the lowest fan setting can ensure a peaceful night’s sleep while enjoying purified air.
