In theory, cloth masks allow the air to move through them, but the fabric acts as a fine enough filter to reduce the distance the exhalation moves. The vented N95 masks that are known to be a problem allow unfiltered air to move out. If the mask shown has filter elements and all the exhaled air moves through them, it might be OK, as long as the pore size of the filter is small enough. (As eye glass wearers know, with cloth and surgical masks the exhaled air tends to go up along the nose, rather than through the fabric/paper as desired. This still protects others, as the exhalation is rerouted and not broadcast long distances away from the wearer)
There was an Australian company selling pliable plastic face masks with built in filters about 8 years ago, when the western wildfires were so bad we weren't supposed to go outside. I think Vince Welch sold them for a while as shop 'respirators', too. They had fairly persuasive marketing materials, but I never found them very comfortable or easy to breath through, and stuck with the 3M half face respirators.
