A HEPA/ULPA air filter box, also known as a HEPA/ULPA terminal housing box, is a specialized air filtration device that is designed for use in cleanrooms and other controlled environments. HEPA (High-Efficiency Particulate Air) filters and ULPA (Ultra-Low Particulate Air) filters are air filters that are able to remove 99.97% and 99.999% of particles that are 0.3 microns or larger in size, respectively. They are commonly used in cleanrooms and other controlled environments, where they are used to remove particles and contaminants from the air in order to maintain a high level of cleanliness.
HEPA/ULPA air filter boxes are typically made of metal or plastic, and are designed to house a HEPA or ULPA air filter. The box is typically sealed with a plastic or rubber gasket, in order to prevent air leakage around the filter. The box is then mounted on the wall or ceiling of the cleanroom, and is connected to the air handling system. This allows the filter to remove particles and contaminants from the air as it flows through the cleanroom.
HEPA/ULPA air filter boxes are commonly used in cleanrooms and other controlled environments where it is important to maintain a high level of cleanliness. They are typically used in industries that require strict cleanliness standards, such as pharmaceuticals, medical devices, and semiconductors. When choosing a HEPA/ULPA air filter box, it is important to consider the specific requirements of your cleanroom, such as the size and shape of the cleanroom, the level of cleanliness required, and the types of hazardous materials that will be used. By carefully evaluating these factors, you can determine the right HEPA/ULPA air filter box for your needs.

How to choose a cleanroom HEPA air filter box?
When choosing a cleanroom HEPA air filter box, there are a few factors to consider:
- Size: Consider the size of the air filter box based on the size of the cleanroom and the amount of airflow required.
- Efficiency: Choose an air filter box with a high-efficiency rating, such as a HEPA filter with a minimum efficiency of 99.97% at 0.3 microns.
- Certification: Make sure the air filter box is certified for use in a cleanroom environment.
- Installation: Consider the ease of installation and maintenance of the air filter box.
- Price: Determine your budget and choose an air filter box that fits your needs and budget.
It is important to consult with a cleanroom specialist or the manufacturer to determine the best air filter box for your specific needs and environment.
