these are a great mask they fit nice and close and provide excellent filtration the 1 star review is missing the whole point of why mask is used for
These are among the very best masks I have tried because they have head loops and not ear loops they fit very well and provide very good protection. it is true that it is less easy to put on a mask with head straps as apposed to ear loops but masks with head loops are always the most effective. If you want your mask to actually work then these are a good product. I have used these when gardening(as i have hay fever) when sanding floors, cutting tiles with an angle grinder, installing loft insulation, pulling down ceilings as well as during the pandemic they are just great. i know they work because i can never smell the item i am working with because of the excellent filtration.
