If you purchase a TOTOBOBO mask between September 1st~17th from this site, please check if you have received a defective mask. The problem is the whole filter tend to fall off very easily. It is easy to check: refer to the photo here: try to open up the mask by graping both filters, the mask should be opened without the filter dropping off. If the filter detached from the mask without much force, then the mask is defective. Please contact totobobomask (at) gmail . com to arrange for replacement mask.
We’ve taken immediate steps to correct this problem. Masks purchased after September 17 are free from such defect.
We apologize for the inconvenience caused.

Yes when I first received the mask I had a few times when the filters came off when I just touched my mask
