Face masks have become mandatory for many countries battling COVID-19, and like any piece of clothing you wear, there’s a myriad of styles and types out there right now.
One type of mask that’s gaining popularity that you shouldn’t use is the one that has a built-in valve in it. In fact, it’s use do more harm than good – so much so that the Medical City is banning anyone that uses said masks from entering any of their hospitals or clinics.
See, the main reason why you wear a mask in the first place isn’t just because you’re protecting yourself from inhaling particles that may contain COVID-19, it’s also to stop yourself from releasing particles from your mouth and nose into the air in case you’re an asymptomatic carrier.
Having a mask that has a valve that allows air to freely flow from your face is dangerous, and defeats one of the main reasons you’re wearing a mask in the first place – to protect others from getting infected.
In fact, a study published in the journal Infection Control and Hospital Epidemiology concluded that the use of masks “may be an additional and under-recognized transmission source.”
That means you should stop using them, pronto.
You should use medical masks, N95 masks, and cloth masks instead which block harmful particles from coming into your body and blocks them from coming out as well.
