How Does a Hardwall Cleanroom Work?

A hardwall cleanroom works by removing particles, contaminants, and pollutants from the ambient air getting into the enclosed space. First, the outside air is passed through the filtration system. This includes passing the air through the primary filters and then through the HEPA or ULPA filter.

These filters will decontaminate the outside air based on the cleanroom cleanliness levels. This filtered air is now forced to get into the cleanroom. Simultaneously, the contaminated air already in the cleanroom gets forced out or recirculated into the filters for filtering again.

– Other people also find these types of cleanrooms easy to clean and maintain their finish. You simply have to follow the manufacturer’s maintenance guide, and you should be fine operating the cleanroom for many years.

– Most are designed to let in light for better ambient working environments. It is why some would not feel constricted into a special building but rather treat it like any other type of building with a higher cleanliness level.

The HEPA filter can remove up to 99.99% of the particles of size up to 0.3 microns in diameter. Such a filter performance is what makes it a favorite among the users looking for a great hardwall cleanroom.

However, the filter needs to be changed when it is damaged or clogged due to years of use. On average, you are advised to change it after 2 to 3 years, depending on the condition. Advise to detect every half a year for class 100 and class 1000. And to detect every year for class 10000, and class 100000. Once find the leaking, replace the filter then.  If it has to filter dusty air all the time, you may have to replace it sooner.

Can You make a Hardwall Cleanroom From an Existing Building?

Yes. This is possible. A cleanroom does not always have to be built from scratch when there is an existing building. You can set it up to be part of the existing building or movable when you set it up on casters.

Is a Hardwall Cleanroom Cleaner than a Softwall Cleanroom, or Vice Versa?

If you look at a hardwall cleanroom’s operation, you can understand why it is commonly preferred as a cleaner option. The hardwall construction provides a better barrier to particle intrusion and more control on how you can adjust the humidity, temperature, and other important aspects of a hardwall cleanroom.

Another significant difference between a hardwall and a softwall cleanroom is that the hardwall models can hold significant positive pressure to prevent particles intrusion. That is not what you get with a softwall cleanroom, as it might have perimeter air gaps.


The hardwall cleanroom has multiple applications so that it can be used in different environments. It is why more people would always consider it when picking new cleanrooms.
