Class 10000 Cleanroom: Understanding Its Significance

Cleanrooms are specially designed spaces where the level of airborne particles, temperature, humidity, and pressure are strictly controlled. These rooms are used in various industries such as pharmaceuticals, biotechnology, aerospace, microelectronics, and food and beverage industries where the presence of even a tiny particle or microorganism can cause catastrophic effects.

One such type of cleanroom is Class 10000. In this blog, we will discuss its significance and the industries that commonly use it.

What is a Class 10000 Cleanroom?

A Class 10000 cleanroom is a controlled environment with a maximum of 10,000 particles per cubic foot of air that are equal to or greater than 0.5 microns in size. These have strict regulations for temperature, humidity, and air pressure control. The temperature is typically maintained between 64-75°F, and humidity is maintained between 30-60%. The air pressure is also kept under control to ensure that there is no contamination from the outside environment.


This type of cleanroom plays a critical role in various industries where maintaining a high level of cleanliness is crucial. In the pharmaceutical industry, these cleanrooms are used for the manufacturing and packaging of drugs, where even the slightest contamination can have serious consequences. The same applies to the biotechnology industry, where the use of cleanrooms is essential for the production of sterile products and research on live cells.

In the microelectronics industry, Class 10000 cleanrooms are used for the assembly and testing of delicate electronic components, such as microchips, circuit boards, and hard drives. The presence of even a small particle can disrupt the functionality of these components, leading to the failure of the final product.

In the aerospace industry, these are used for the manufacturing and testing of spacecraft, satellites, and other related equipment. These cleanrooms ensure that the parts used in space missions are free from any contaminants that could cause malfunctions during operation.

Similarly, cleanrooms are employed by the semiconductor industry to produce microchips and other electrical components that are used in a range of electronic devices, such as cell phones, computers, and gaming consoles. The high level of cleanliness in these cleanrooms ensures the quality and reliability of these components.

Cleanrooms play a critical role in the food and beverage industry. They ensure that products meet the highest standards of safety, purity, and quality. The controlled environment in the cleanroom minimizes the rate of bacterial growth, which helps to extend the shelf life of products. This reduces the amount of food waste, which is a significant problem in the industry.

The best approach to keep these environments clean and hygienic is using air filters.

Air filters are used in cleanrooms to remove contaminants from the air that could otherwise compromise the integrity of the cleanroom environment. They work by trapping particles and microorganisms in the filter media, preventing them from circulating in the air and potentially contaminating the products or processes in the cleanroom.

The most commonly used filters in cleanrooms are High Efficiency Particulate Air (HEPA) filters, which are capable of removing particles as small as 0.3 µm with an efficiency of 99.995%.
