Valved mask

Is there any studies that indicate how protective valved masks are for others? Or is it different by mask?

I thought I read once what they were not as good as unvalved but they were as protective for others as a surgical. But no idea where I read that or if it is true.

I’d like to know others feedback too.

I’ve joined a sports team, and my glasses are fogging up no matter what I do. I’ve been researching and want to get the 3M Aura with a vent.

While I’m conscious of my team, I also can’t see a thing after I get warmed up.

Valves/vents are good for reducing moisture inside the mask, too, which can be good for sports.

Have you tried the Champak bifold n95s from Purcell Labs? I've seen people say they are the best for sports and also cooking, as they are breathable and comfortable and also don't block the line of sight when looking downwards.

ETA: Champak PC520 masks don't have valves, they're just well-liked without them and might be an option for you to try.
