Can We Reuse KN95 Masks? Rethinking Our Mask Practices

With COVID-19 cases skyrocketing in my area (we’ve reached a staggering 22.3% positivity rate), it’s time for my family to reassess our lax approach to mask-wearing. I confess, I often reuse my stylish cloth mask, while my kids don brand-new disposable masks each day, which unfortunately don’t fit very well. Given the rise of the Omicron variant, it’s clear we must step up our protection and consider investing in KN95 masks.

However, investing is the key word here. While KN95 masks are just as effective as medical-grade N95 masks (both types filter out 95% of tiny particles), they are generally more affordable. Still, equipping my family of four with fresh KN95 masks daily would cost around $240 for just one month—not a trivial expense.

This brings me to a crucial question: Is it safe to reuse KN95 masks? Unfortunately, there isn’t a consensus on this matter. Mark Thompson, founder of Safety Solutions Co., expressed his disbelief that some individuals wear the same mask for days or even weeks without changing it, which he described as not only foolish but also very risky, especially without proper decontamination.

Most of us likely don’t own a decontamination machine, but Dr. Sarah Lee, an infectious disease expert, suggests a simple method: place your used mask in a plain paper bag for 24 to 48 hours. Dr. Emily Roberts, a medical officer at HealthWise, adds that it’s not the bag that works magic, but rather the process of isolating the mask to prevent contamination and allowing it to dry out, which helps reduce viral survival.

According to Dr. Mark Palmer, an infectious disease physician, while healthcare workers should definitely change their masks daily, the average person might reuse a respirator for up to a week, provided they inspect it regularly for any damage or dirt that could compromise its effectiveness.

Ultimately, there are no strict guidelines, and it’s an individual decision based on personal circumstances. For my family, with Omicron’s high transmission rate looming, we’ve decided on a “better safe than sorry” approach, opting to discard our masks at the end of each day. Sure, we might need to adjust our budget and cut back on some luxuries, but until we get COVID under control, I believe it’s worth the investment.

Summary:

In light of the current COVID-19 surge, families are reevaluating their mask practices, particularly in relation to the reuse of KN95 masks. While some experts suggest reusing them for up to a week with proper care, others recommend daily changes, especially for healthcare professionals. It’s essential to assess individual circumstances and prioritize safety.
