Amid the COVID-19 pandemic, if you exit wearing a valve mask you purchased to tackle pollution, you ought to consider changing it. Health experts have advocated for face masks to stop COVID-19 spread, but masks with valves only filter inhaled air. So, if you’re a COVID carrier, you'll infect others if your mask features a valve.

None folks love wearing masks, and we’re all trying to find the foremost comfortable options. So, maybe you’ve wondered about those masks with the plastic valve near the nose – is that this the solution I’ve been looking for? Will a valve solve my mask woes?

The Basics: Face Masks

Confused by all the various face masks out there? Here’s a breakdown of what they are doing .

Sadly, no. While a valve may make breathing a touch easier, that valve could be spraying your germs everywhere at high velocity whenever you exhale – defeating the aim of even wearing a mask.

Valve filters filter the air you inhale . But they don’t filter your exhaled breath in the least . once you exhale through a mask with a valve, not only does your unfiltered breath escape, but the force of the exhalation against the tiny opening of the valve can create a high-pressure stream of germs being blown out into the encompassing air.

To understand this better, believe your sink setup. If you switch on the tap , the water flows through the large-diameter spout under low . But if you engage the sprayer, an equivalent water flow gets directed through small holes that make a high-pressure stream which will spray across your kitchen (as anyone who’s ever playfully sprayed their kid or spouse knows).

Keep in mind that the most purpose of wearing a mask isn't to filter the air you’re inhaling , but to scale back the quantity of your exhaled breath that gets into the environment.

‘Valve masks work for pollution, not COVID-19’

Arvind Kumar, Chairman, Centre for Chest Surgery and Director in Institute of Robotic Surgery at Sir Ganga Ram Hospital, explains, “In COVID-19, the first purpose of the mask is to guard others from you. The secondary purpose is to guard yourself. In pollution , the sole purpose is to guard yourself. that's the elemental difference. In pollution, you would like to wash 100% of the air you're inhaling and what you're exhalation are often allowed to travel out back to the environment without resistance in order that you do not rebreathe your own air. except for COVID-19, you would like 100% filtration during exhalation and effective filtration during inhalation.With a valve mask, everything that you simply breathe through the mask is filtered, but once you exhale , the valve opens and allows unfiltered air to return out. So, if one is infected with COVID-19 and is wearing a valve mask, they're infecting others.”
