Be careful
I purchased 2 small masks for my daughter to use for school.  I read some reviews that mentioned the filters were difficult to put in.  So, prior to putting the filters in, I read instructions,  looked at a diagram, and tried to be very careful handling them.<br /><br />On both masks, when putting the filter in, the filter split in two at the seam.  Unfortunately, this happened right before school and I didn't have time to get another mask.  I had to sew the filter together so my child could use her mask.<br /><br />I am very unhappy.  I followed directions,  handled the mask and filter with care, and BOTH masks had the same issue.
