The Semi-Automated Dry Heat Bioburden Reduction Model, also known as The Hot Box is capable of decontaminating 24,000 masks daily. When the model was created, PPE materials were extremely limited -  providing a safe option for decontamination will allow the reuse of existing materials. At Bioburden Reduction Systems, we are expanding the capabilities and uses of The Hot Box to a wider reach of consumers.
