From the Research
N95 masks should not be worn by individuals with severe respiratory conditions, such as COPD with a modified Medical Research Council dyspnea scale score ≥ 3 or FEV1 < 30% predicted, as it may exacerbate their condition and cause distress. Contraindications for wearing N95 masks include:
- Severe respiratory conditions like COPD or asthma where the increased work of breathing could cause distress 1
- Claustrophobia or anxiety disorders that may be triggered by the sensation of restricted breathing 2
- Facial trauma or recent facial surgery that prevents proper mask fit
- Children under 2 years of age due to suffocation risks
- People with cognitive impairments who cannot remove the mask independently
- Individuals with facial hair that interferes with the seal, as it may compromise the mask's effectiveness These contraindications exist because N95 masks create resistance to airflow, requiring more effort to breathe, which can exacerbate underlying respiratory conditions and cause physiological stress in vulnerable individuals 3, 4. For those with contraindications who still need respiratory protection, alternatives like loose-fitting surgical masks or powered air-purifying respirators may be more appropriate. It is essential to prioritize the individual's health and safety when deciding whether to wear an N95 mask, considering the potential risks and benefits in each specific situation.
