The Role of Garment Filtration Efficiency in Protecting Critical Environments

As we draw closer to the containment of the coronavirus, we should all remain humbled by the fact that the spread of a microorganism shut down much of our technology-driven world for beyond a year with its rippling effects still being felt today.

As a manufacturer of superior cleanroom apparel, Lakeland Industries has always treated the filtration efficiency of our CleanMax™ cleanroom garments as a critical measure of performance. Every person who has worn a mask in response to the coronavirus has had a basic lesson in filtration efficiency over the past year. Medical masks versus N95 masks, one mask or two, true PPE or general face coverings?  

Why Does Particle Filtration Efficiency Matter?

Even with the most thorough risk assessment, the true cost of an unimaginable risk is impossible to determine yet, as last year proved, those risks exist. However, the risk of contamination to your cleanroom employees, processes, products, and profits can be lessened by choosing the best cleanroom garment on the market today. CleanMax™ offers 99.999% bacterial filtration and 99.999% particle filtration efficiency when tested in accordance with ASTM 2101. Our competitors’ garments offer anywhere from 96% to 98.4% Bacterial Filtration Efficiency. Does 1.5% to 4% additional filtration performance mean a lot? In the microscopic world of viable organisms in aseptic cleanroom applications, it carries a lot of weight and added risks.  

Reusable cleanroom garments pose an even greater risk of contamination as they deteriorate through multiple launderings and irradiation sequences while aging out of an unknown lifecycle. While laundries can generalize performance of a reusable cleanroom garment, they cannot account for the cumulative variables and challenges that each individual application and wear places on the individual garment. Multiply the risk by the number of employees gowning and the number of times that garment is worn and then subsequently processed. With each cycle the garment becomes less of a barrier to contaminants offering less and less protection. What is the cost of the risk associated with each time an aging reusable garment is donned by a cleanroom employee?...
