Calumeo: An award winning, point-of-care solution for N95 mask reuse

The N95 shortage issue

N95 respirators are specialized, single-use face masks that form a complete seal to the users face and filter out airborne viruses. The COVID-19 pandemic has resulted in a critical shortage of N95 masks and the US dept of health and human services estimates that 3.5 billion N95s will be needed in this year alone.

However, 3M, the largest domestic manufacturer of masks, aims to produce only 400 million this year and, in aggregate, only 1% of the needed N95 supply is currently available for use in the US. This has led to a new industry in disinfecting N95s masks for reuse.

Problem with current solutions

Most existing solutions use vaporous hydrogen peroxide for disinfection.

Drawbacks of this technology include:

long process times (>8 hrs)
off-site processing (requiring significant infrastructure to collect and re-distribute masks)
mask not returned to original user
persistent noxious odor
skin irritation

Calumeo’s custom N95 disinfection device offers a chemical free solution for healthcare workers to disinfect their personal N95 mask at their worksite, in approx 75mins, while preserving mask fit and function.

Non-chemical cleaning [unlike vaporous hydrogen peroxide method, we use heat]

Short cycle time (75mins) [unlike the bulk disinfection process that takes 8 hours]

Simple to operate
