I like the easy use
The activated charcoal face mask filter insert was the perfect addition to my COVID-19 mask. Form, fit, and function was exactly as advertised. The ordering and delivery process went flawlessly. Great price. Outstanding service from start to finish.
They are perfectly fine.
Thank you for sending them so quick
I bought these filters for my mask. I don't have any complaints. I'm just glad that they were available online without me having to go to the store.
What a great product—adding a good filter—and sense of security—without bulk, discomfort or worry! Easy fit.
