As COVID-19 infections surge once again, driven by the highly transmissible BA.5 Omicron subvariant, many are seeking ways to protect themselves and their loved ones. With the Centers for Disease Control and Prevention (CDC) yet to update its mask guidelines since February, confusion about the best masking practices is understandable. If you’ve transitioned from cloth and surgical masks to N95 respirators or similar options, you may be considering whether double masking is an effective strategy to minimize transmission.
To shed light on this topic, we consulted two infectious disease specialists who offered valuable insights into effective masking for BA.5 and beyond.
The Essentials of Double Masking
According to Dr. Emily Carter, MD, Ph.D., an expert in infection prevention at Riverside Medical Center, wearing two masks can enhance particle filtration, thereby potentially reducing viral exposure. However, the effectiveness of double masking depends on the type of masks and their arrangement (for example, wearing a cloth mask over a medical mask). “The actual impact of double masking is difficult to quantify,” she notes.
Dr. Nathan Wells, a pediatric infectious disease specialist at Oakwood Health, emphasizes that the key to reducing viral exposure lies in achieving a snug fit, regardless of how many masks you wear. “The CDC advises that a well-fitted mask is crucial, so if you can ensure a proper fit, double masking may not be necessary,” he says. “However, if a single mask doesn’t fit well, layering a cloth mask on top of a disposable one can help improve the fit.”
A secure fit around the nose and chin is vital, as Dr. Carter explains: “Using safety equipment incorrectly diminishes its effectiveness. For instance, a seatbelt is only beneficial when fastened properly. Masks with exhalation valves or those that don’t cover both the nose and chin are less effective.”
Current Guidelines on Double Masking
As of now, neither the CDC nor the World Health Organization advocates for double masking. Dr. Carter highlights that the CDC prioritizes comfort and fit in its guidance. “It’s not just about the number or type of masks; comfort is essential. If wearing two masks causes discomfort or shortness of breath, it’s better to choose a different option,” she advises.
That said, given the emergence of BA.5, both experts agree that if double masking provides a better fit without sacrificing comfort, it could be a practical choice. Dr. Wells mentions that while higher filtration masks like N95s offer superior protection, options like medical masks combined with vaccination and hand hygiene can provide effective protection and may be more comfortable for extended wear.
“Wearing a mask that doesn’t fit properly is almost as ineffective as not wearing one at all,” adds Dr. Carter. “It’s like wearing a single shoe in the rain—you may stay partially dry, but you won’t be comfortable.”
The Effectiveness of Proper Mask Usage
Ultimately, a well-fitted mask offers reliable protection against not only COVID-19 but also other respiratory viruses. Dr. Wells states, “Our experiences with COVID have demonstrated that masks are effective. This realization should extend to protective measures against other respiratory illnesses, especially during high transmission periods like flu season.”
In summary, a single, well-fitting mask is significantly more effective than no mask at all. Ensuring that masks are comfortable, well-constructed, and combined with good hand hygiene and vaccinations will enhance overall safety.

Summary: With the rise of the BA.5 Omicron subvariant, many are questioning the necessity of double masking. Experts recommend focusing on the fit and comfort of masks rather than just the number worn. While double masking can enhance protection if a single mask isn’t fitting well, wearing a properly fitting mask is crucial.
