How Does a HEPA Filter Work?

How a helpa filter works

Figure 10: How a Hepa filter works

Since the hepa box comes with the high efficiency filter, it is best if we talk about it too. You would want to know how it works and what makes it great for your cleanroom.

The HEPA filter is a unique type of filter that meets the most rigorous air filtration requirements for different applications.

The filter can remove up to 99.99% of the particles in the air even as small as 0.3 microns. Each time you get a filter labelled HEPA, then you should know that it comes with such a performance in terms of filtering the air.

So, how does the HEPA filter work? Well, the filter works by using three different mechanisms which include interception, impaction, and diffusion.

HEPA filter of HEPA box

Figure 11:  HEPA filter of HEPA box

Interception is when the particles in the airflow get captured. So long as the particles come into contact with the filter, then they get stuck on the filter fibers and do not go past the filter.

Impaction is when the large particles are captured by the air filter. They are large in the sense that they cannot handle the changes in their airflow. Once the air goes through the filter, they crash into fibers and get embedded into them.

Diffusion on the other hand is when the particles in the air flow move in a zigzag motion while trying to get through the HEPA filter. When this happens, it increases the chances of them getting trapped in the filter fibers.

From three various methods mentioned above, it is easy to see why a hepa box would be necessary to filter the air better.

The air that gets past the hepa box will have 99.99% of the particles removed. You can now be sure to maintain the clean room integrity better with the hepa box now.


Why Should You Use HEPA Filtration In a HEPA Box?

HEPA filtration is considered the gold standard in the filtration world. This is because it is able to handle different filtration standards for various applications that you might have to handle.

Since HEPA filtration is good, you will find it being highly recommended by asthma and allergy specialists. It explains why such filtration type will come in handy to reduce the airborne allergens and can also help in maintaining clean room integrity.

At this point you might be wondering, what more can the HEPA filter remove from the air? Here is a list of the things that the HEPA filter can remove.

–      Bacteria

–      Fine dust

–      Dust mites

–       Mold spores

–       Pet dander

–       Lint dust

–       Pollen and more.

Unlike the other types of filters, the filter in the hepa box will perform great even with months of use. They have the ability to still work great even if they get older. So, how often should you change the hepa box filter?

Zonsteel recommends cleaning or replacing the filter every six months.

Upon opening the hepa box, you will notice a change in the color of the filter over the six months. It will mostly likely have turned from white to brown.

It comes down to the extend of the dirt. Some filters are best just changed rather than trying to clean and reuse them.


Can a User Clean a HEPA Filter?

Figure 13: A personnel cleaning a hepa filter

If you are asking yourself this question, you probably see that the hepa box filter is dirty and it needs cleaning or replacing.

Before you can start cleaning the filter, check to see if it is labelled permanent or washable. If it does not have such a label, do not attempt to clean it as it will affect its performance making it not to meet the set out standards.

To clean the filter in most cases it will involve using running water or a vacuum to remove the particles.

If the filter is not designed to be washed, then there can be damage to the fibers. It might look good, but the fibers might be broken or stretched out. You will not notice this at first, but if you do a particle counter test, you will notice that the filter is not working as expected.

For those that get the washable filter, follow the manufacturer instructions on how to clean the hepa box filter. Once it is cleaned, let it dry before putting it back into the hepa box.
