Problem is probably that the masks are supposed to be single-use when used as protection and you're meant to replace them even when moving between different places. You're also not meant to wear them for extended periods of time because they supposedly get less effective when they get wet from the moisture of the air you exhale. They also aren't washable so you would need to dispose of them after use.

The electrostatic filter doesn't work effectively when damp, eg after prolonged exposure to humid breath. There's an incredible amount of engineering that goes into PPE.
