I have used the filter and I have COPD so I am high risk. I felt protected while using the filter but I did have some anxiety about breathing only due to my COPD. Highly recommend!
I expect is an additional layer of protection and that's what counts.
Love these masks, have bought for my parents, nieces, nephews, in laws, everyone loves how soft they are and the filters. We keep buying them. My fussy 8 year old, also has no problem wearing them because they are so comfortable. She gets compliments on the designs all the time which helps reinforce her wearing them.
Great experience all around! I have tried many different types of masks and this is the most comfortable for teaching.
These offer a great added layer of protection at just the right size.
