The filter needs to be put inside of the mask, between two layers of fabric.

Love the mask fit, quality and feel. I'd like the strings to be a bit longer so I can tie them together behind my head instead of ears, to avoid cutting into ears when wearing for longer periods of time. Other than that the mask fits well, doesn't slip too much and looks good if that matters to you.
Fine. Very comfortable. The HEPA filter offers another layer of protection.
