What are Clean Room HEPA Filters?

Different Sizes of Cleanroom HEPA Filters

The cleanroom HEPA filters are specialized filters important for removing particulates, dust, and other suspended solids in the cleanroom air. So long as these particulates are over 0.3 microns in size, the cleanroom HEPA filters will remove them.

When the cleanroom HEPA filter is in place, it should be able to remove up to 99.97% of the particulates. It is easy to see how this will leave you with the best air quality.

What are the Materials Used to Make Clean Room HEPA Filters?

Sunnyda understands the importance of HEPA filter performance. It is why the company uses high-quality ultra-fine glass fiber paper as the main building component of the cleanroom HEPA filter. This type of material is all about improving the HEPA filter performance and durability. You will not need to change the HEPA filter any time soon.

You will also find that the cleanroom HEPA filters can have folded papers, aluminum foil boards, or other materials as the dividing plates. In most cases, it will largely depend on the use of the cleanroom HEPA filter.

Are the Clean Room HEPA Filters Customizable?

Yes. It is possible to customize the cleanroom HEPA filters to suit your needs. The customization is largely based on the air volume you need and the cleanliness level of your cleanroom. Once you provide this information, Sunnyda can come up with the best cleanroom HEPA filter for your needs.

HEPA Filters Vs. ULPA Filters. What is the Difference?

An Installed HEPA Filter

The chances are you will come across HEPA and ULPA filters when looking for cleanroom filters. It is worth learning about the differences between these two filters to understand where each one would apply.

Filtering Performance

The biggest difference between the HEPA and ULPA filters is the filtering efficiency or performance. The HEPA filter can remove up to 99.97% of the contaminants. These contaminants would be as small as 0.3 microns in diameter. As for the ULPA filters, they would remove 99.99% of the contaminants of diameter 0.12 microns or more.

As you can see, the ULPA filter would remove a lot more contaminants from the cleanroom. This is an assurance you will always have the best clean room generally.

You are likely to come across some other materials that claim cleanroom HEPA filters would remove up to 99.99% of the contaminants. As much as it is possible, keep in mind that its filtering capacity still remains for contaminants larger than 0.3 microns.

Airflow Capacity

This is the amount of air that can move through the cleanroom HEPA filter at any given time. The ULPA filter is denser so that it can filter smaller particulates. For this reason, the airflow will be 20 to 50% lower compared to when using the HEPA filters having the same size.

Having a lower air capacity means that more power is needed to move more air across the ULPA filter. That is not something most people would want when the cleanroom HEPA filters can still provide the best cleanroom conditions. It is why the ULPA filters are used only when necessary.

The Lifespan

The average lifespan of these filters also varies a lot. The cleanroom HEPA filters can last for up to 10 years, depending on the conditions of where it is used. As for the ULPA filters, they will have an average lifespan of 5 to 8 years.

The cleanroom HEPA filters often have a better lifespan because there is better airflow. So, it will take a longer time for it to clog or meet its maximum filtering performance. If you do not have to replace the HEPA filters more often, it means you do not incur a lot of unnecessary expenses too. It is why more people are inclined to consider the HEPA filters.

The Price

From the filtering efficiency, you can tell that the ULPA filters would be more expensive. This is because they are more efficient at filtering the different contaminants than the HEPA filters. The ULPA filters will cost an average of 35% more than the cleanroom HEPA filters.

What Are the Common Types of HEPA Filters from Sunnyda?

Sunnyda makes a wide range of HEPA filters. They include the following;

• High-efficiency filters with partitions

• High-efficiency filters without partitions

• Large air volume high-efficiency filters

• Ultra-high efficiency filters

There can be more types of cleanroom HEPA filters mostly based on your needs. Go ahead and pick the right cleanroom HEPA filter based on your needs for one.

How Does a Clean Room HEPA Filter Work?

Up-close Look of a Cleanroom HEPA Filter

The cleanroom HEPA filters use a four-step process when filtering the particulates from the airflow going into the cleanroom. The first process is sieving the large particles once they hit the filter at a high speed. As the air keeps on going through the filter, the finer particles are further trapped by the mesh fiber in the subsequent layers of the cleanroom HEPA filter.

Each time the air is moving through the filter, the particles further collide with the fiber material thus keeping them from getting past the filter. On average, the cleanroom HEPA filter will remove up to 99.97% of the particles from the air leaving you with better air quality.

How is the cleanroom HEPA Filter Different from Standard Air Filters?

There are some systems that would have standard air filters too. Well, the standard air filter will mostly remove medium to large particulates from the air. This filter will also not have the best capability to remove small micron-sized particles from the airflow.

If you have to remove anything smaller than a micron, this means you switch to a HEPA filter. A particle smaller than a micron is something the eye cannot perceive. The smallest particulate an eye can perceive is 10 microns. So, it is easy to see why a HEPA filter with a filtering capability of 0.3 microns is quite impressive.

The cleanroom HEPA filters can be used in different health industries, especially if there is a need to contain bacteria and viruses.

How Can You Make an ISO Environment with Clean Room HEPA Filters?

The ISO environment is what determines the cleanroom class. On average, you will need multiple cleanroom HEPA filters set up in an area to ensure there is the best coverage to achieve an ISO environment. It is recommended that you get yourself a 60 to 80% coverage range for a room to make it an ISO environment. This could be 3 to 4 HEPA filters for most rooms, but it can vary too if it is a larger cleanroom.

Let us say you are in the liquid filling industry. This means you have to set up the cleanroom HEPA filters over the filling and capping areas. Such helps in keeping the particulates from falling into the open containers.

So, before you can decide on the number of cleanroom HEPA filters, there might be a need for getting yourself a proper survey by a technical team. This will help you pick enough cleanroom HEPA filters to handle the job.

Why is Cleaning a HEPA Filter a Bad Idea?

A Comparison Between A Clean and Dirty HEPA Filter

As much as some people would want to clean their HEPA filters, it is not recommended. You may want to consider replacing the HEPA filter rather than cleaning it. Also, only clean the HEPA filter if the manufacturer recommends it.

Cleaning your cleanroom HEPA filter can be a dirty job. You should consider taking it outdoors for the best cleaning. Or else, the cleaning process is likely to introduce pollutants into the modular cleanroom area.

You need to also consider that you might inhale the contaminants and pollutants when cleaning the HEPA filter. So, even if you are cleaning the HEPA filter outdoor, you need to have a respirator too. Sometimes inhaling such pollutants could easily trigger an allergic reaction.

You may use a vacuum to clean the HEPA filter. However, there is no guarantee that the filter will still be in great working condition as a new one would do.

Also, you have to wait for the filter to dry before using it. A wet HEPA filter can always lead to mold forming on the filter surface. So, if you used water to clean the HEPA filter, give it around 24 hours for the filter to dry completely.

What are the Common Tests for Clean Room HEPA Filters?

It is crucial to know if the cleanroom HEPA filters are working as expected. To make this possible, you need to perform several tests to ascertain their performance.

There are many tests available to consider, however, sometimes simple tests can also help understand more about the cleanroom HEPA filter performance. The most basic HEPA filter test is the smoke test. You can use a smoke machine to learn more about how the airflow moves through the HEPA filters.

When using a smoke tester, ensure there are no blockages, turbulences or the smoke sitting stagnant. This can easily lead to poor airflow. The airflow always needs to be smooth.

It is advisable to conduct several performances and filtration efficiency tests severally over the months. This helps you to note if the filter is not working great and requires replacement.

If you are not sure where to begin to test the cleanroom HEPA filters, talk to Sunnyda. The company can help you identify the best testing methods you can consider for your HEPA filters.

What is the Pressure Difference of Air Across the Clean Room HEPA Filter?

The pressure difference is the correlation between the pressure drop over the filter, airflow, and filter size. There will always be a pressure drop in the airflow after using the HEPA filter for a while. The pressure drop starts from 250 Pa to 450 Pa. Always check the HEPA filter manufacturer manual to determine the overall pressure drop.

It is important to always monitor the pressure drop over the cleanroom HEPA filters. If the pressure drop is more than 450 Pa, then it should raise more concerns. Keep in mind that HEPA filters will mostly handle pressure drops of up to 1000 Pa, before it is too dirty that its efficiency is significantly lower.

Whenever the pressure drop is too high, there might be the need to replace the filter altogether. Check the ventilator performance, energy bills, and more. These are performance analysis aspects to keep in mind to see if the HEPA filter is no longer effective.

If you want to improve the overall lifespan of the filters, you should always work with the rated airflow. This will help improve the overall running costs too of the cleanroom.

What Should You Consider When Picking a Clean Room HEPA Filter?

Vacuuming of a HEPA Filter

Here are some quick tips to keep in mind if you are going to select the best cleanroom HEPA filters.

• The size of the cleanroom. Get enough HEPA filters to handle the air quality needs in your cleanroom.

• The filtered energy use rating. The last thing you need is to spend so much on energy use when you have a cleanroom HEPA filter. So, look at the possible energy use of filtering the air to get the right one.

• The price will also be a big factor for some users. So, do some research to find some of the best deals on cleanroom HEPA filters.

• The reviews about the brand are also crucial. They will help you pick the best filter to ensure the best value for money.

• The maintenance needs of the cleanroom HEPA filter are also important. No one wants to keep working on their HEPA filters in the name of maintenance when it should be servicing the cleanroom.

What is the Common Reason for a Clean Room HEPA Filter Failure?

If you do not take good care of the cleanroom HEPA filter, then it is likely to fail. The best part is that you do not need to perform regular maintenance on it. Check it every three to six months and vacuum it where necessary.

Also, ensure its HEPA box is correctly sealed. This will generally help to prevent any cases of leakages that could also lead to premature failure of the HEPA filter.

Consult your product manual to learn more about why caring for your HEPA filter correctly will lead to better performance and lifespan.

When Should You Replace the Clean Room HEPA Filter?

The lifespan in most cases is situational. Sometimes the HEPA filter might need replacing more often when other times it can last longer.

If the location is dirtier, it means you have to replace the HEPA filter more often. It is advisable to replace the HEPA filter every three to five years. In case you are using it in the most critical and intense operations, replace the HEPA filter every one to two years.
