Review on Respirator Replaceable Washable Suitable Activities by George Kapoor

1. Difficult to assemble. There are two black plastic parts for each of the two holes. The first piece is best trimmed using a ballpoint pen to push the fabric along the edges. The second plastic part is then twisted to lock it in place. It's easier to do once you figure out how to do it.2. The grey-white filter blocks most of the air except for the seam where most of the air enters. In other words, most of the mask is too heavy to breathe, and the seams are imperfections that allow air to pass through without being filtered. If you are skeptical, put different parts of the filter to your mouth and try to inhale. Almost impossible, except with defective stitching. I returned it for a refund.
