Solutions / Problem areas



Bioburden, or microbial growth, refers to microorganisms contaminating a surface, product, or fluid. Bioburden, or microbial growth, is caused by airborne microbes, dust, dirt, mold spores, bacteria, viruses, and particles shed from people, products and equipment. People shed 3.5 kg of particles from their hair and skin every year, and every breath may contain viruses, bacteria and microorganisms. Bioburden is mobile and continuously growing. It touches and contaminates everything.


To reduce bioburden, it is necessary to minimize the number of particles in the air by using protective gear, clean all surfaces in the facility meticulously on a daily basis. Our cleanroom solutions, QleanSpace ISO, QleanSpace USP, QleanSpace GMP, and QleanSpace FDA cGMP, all create a controlled environment using multiple individual HEPA 14 fan filter units and air locks to maintain a negative or positive air pressure. The monitoring system helps control the number of particles in the air, as well as air pressure, relative humidity, and temperature inside the cleanroom.

Our freestanding air cleaners with HEPA 14 filters can create near-cleanroom conditions when it is not possible to have a cleanroom. They are also useful to clean the air outside of the cleanroom to further improve its performance.
