It's the reality of our new world; masking up is mandatory, and the latest health advice is to switch to a disposable N95 mask in the battle against Omicron. Still not sure what an N95 is? Here's the deal: When appropriately worn, N95 respirators provide the most protection against COVID-19, Jyotsna Shah, PhD, President of COVID-19 lab IGeneX, Inc, should know. With over 40 years of research experience in immunology, molecular biology and microbiology, she says choosing a face mask, make it an N95 respirator mask. "As the name suggests, N95 respirators have been approved by the National Institute for Occupational Safety and Health (NIOSH) and filter up to 95 per cent of particles in the air that could contain COVID-19." While traditionally considered a single-use mask, this isn't quite the case anymore. "With limited access to N95 masks globally and the climbing prices, Dr Shah says you can safely wear your N95 up to five times before it's time to toss it. With every use of your N95 mask, the straps will loosen slightly, breaking the tight seal around your face." She recommends purchasing a pack of N95 masks and rotating day by day, ensuring that you get the best use out of each mask. The Centers for Disease Control and Prevention (CDC) recommends this five-time rule, too, but the guideline is specifically for healthcare providers, so there might be wiggle room for the rest of us.
To understand the signs that your mask has gone through too much wear and tear Dr Shan suggests checking your face mask before you wear it. "Look for obvious damage such as tearing in the mask is a sign to replace immediately. Keep a careful eye out for fraying straps too. This is another sign to replace your mask as it indicates that it won't create a strong enough seal around your face to protect you," says Dr Shah. For example, if you wear your N95 to play tennis, you might want to swap it out. Another thing of note? Dr Shah says you cannot extend the life of your N95 by throwing it in the washing machine. "I do not recommend using your N95 mask if you've run it through the washing machine. Unfortunately, washing cycles can degrade the integrity of such a mask and render it useless," she says. Finally, you'll also want to make sure you're sanitising your hands before taking your mask on and off and storing your N95's somewhere clean and dry.
The take-home: Make sure you're purchasing your N95 from a reputable retailer. Experts estimate that up to 60 per cent of N95's are counterfeits. Here are some of the approved masks below.
