Reprocessing Personal Protective Equipment with hydrogen peroxide vapor

In September and November of 2020 a study, led by researchers from Memorial Hermann Texas Medical Center, Houston, conducted research on the use of hydrogen peroxide vapor (HPV) technology on a large scale to reprocess Personal Protective Equipment in a healthcare system.

The researchers were able to recapture and reprocess 29,706 units using HPV, with approximately 25% loss mostly on surgical or N95 face masks, because of damage.

In a small pilot, 24 masks, representing 7 different N95 models, underwent HPV cycles, post-cycle visual inspection, and fit testing. A fit factor of more than 100 was considered acceptable for control and reprocessed masks. Of the reprocessed masks, two failed fit testing. The other 22 did not differ from the control masks, while for the other PPE wearables there were no alterations detected.

The rate of sanitization was validated using Geobacillus stearothermophilus biological indicator discs. No growth was seen on the plates containing the discs that underwent an HPV cycle.

Reprocessing cost per one peice of PPE is approximately $1.47. Commercial companies offer a similar services that averages $2.67-$6.25 per unit.

Having the ability to reprocess PPE in house allows them to be returned into circulation more rapidly, and cost effectively, the researchers say.

One such solution for Sanitizing Personal Protective Equipment within the Healthcare system is the ViTralizer. Simply assign a “sanitization room” place the PPE inside, fill the reservoir (about 1 qt), set the room size, push start and leave the room. In less than an hour the PEE will be properly sanitized. It’s that easy.

Another benefit of using the ViTralizer is the mobility of the unit. The “ViTralizer”  is capable of sanitizing over 17,000 cubic feet  (2,125 Square Feet @ 8 ft ceilings) in one run.  If you need more space covered, just move the machine to a different location and run it again.
