Issues
The main concern is the higher cost, challenges in training HCWs to safely remove PAPRs without contamination, the need for re-training if infrequently use, inability to re-use disposable filters between patients, the need for explicit decontamination and recycling of blower units, potential compromise of disposable components through inappropriate attempts to sterilise and reuse to conserve supply leading to infection risk, communication challenges due to the fan noise, and increased risk of infection from doffing the additional layers of PPE.(1, 23, 100, 104)
