A biological cleanroom refers to a controlled environment where the concentration of suspended microorganisms in the clean room air is strictly maintained within specified threshold limits. It primarily controls airborne contamination from viable particles, including bacteria and other microorganisms, and is categorized into biological clean room and biological safety clean room.

Definition of biological clean room:

A biological clean room is a specialized cleanroom where airborne microorganisms serve as the primary focus of contamination control. Airborne microbes, such as bacteria, rickettsia, and viruses, rarely float in isolation; instead, they typically congregate or attach to airborne dust particles to form suspended bio-contaminants. Individual bacteria generally range in size from about 1~100μm, while individual viruses measure approximately 0.008~0.3μm.

The individual size of rickettsia falls between that of bacteria and viruses. When these populations attach to airborne dust particles, their combined size is typically around 5~10μm. Consequently, air filtered through a sub-high efficiency filter (counting efficiency of ≥0.5 μm particles ≥95%, <99.9%) can be regarded as sterile air. Following the introduction of the cleanroom, this concept was rapidly adopted across biological cleanroom technology. Biological cleanrooms are widely utilized in pharmaceutical manufacturing, sterile animal breeding, hospital operating rooms, burn treatment units, leukemia isolation wards, food production, and high-grade cosmetics production. The application of biological clean rooms throughout pharmaceutical production in China has become increasingly widespread.

Where is the biological clean room generally used?

1、Perating room: specialized orthopedic surgery, hip joint replacement, prosthetic heart valve implantation, internal organ transplantation, and major neurosurgical procedures that require aseptic operating environments.

2、Special wards: intensive chemotherapy for leukemia, malignant tumors with reduced white blood cell counts, aplastic anemia, immunosuppression before and after organ transplantation, and deep burn care requiring aseptic ward environments.

3、Sterile preparation: Sterile preparations are medications administered directly into the human body. Because patient health and life safety are at stake, the entire preparation process must remain completely sterile.

4、Laboratory animal breeding room: for safety testing and pathological studies of medical food, test animals must be maintained in a biological clean environment.

5、Pharmaceutical industry: Pharmaceuticals are vital to human health and life safety, requiring pharmaceutical manufacturing processes to be strictly protected against microbial contamination.

6、Cosmetics industry: Cosmetics provide an ideal nutrient source for microorganisms, making them highly susceptible to microbial contamination. Contamination around the eyelids and eyelashes can lead to serious eye ulceration, conjunctivitis, and related conditions.

7、Food industry: Traditional high-temperature sterilization often destroyed essential food nutrients, compromising natural color, aroma, and texture. Utilizing sterile sealing tape and aseptic filling effectively preserves food quality, extends storage life, saves energy, and improves efficiency.

8、Biosafety: Genetic engineering, drug pathology testing, and national defense research require sterile, dust-free environments to prevent the accidental release of high-risk viruses and radioactive materials that threaten human health and cause environmental pollution.

The biological safety clean room should be kept under negative pressure and is suitable for bioengineering in infectious disease laboratories, genetics, and vaccine research.
