Review on Replacement Filters Without Continental Luxury by Vincent Poolaw

These filters are great. They are very easy to swap out when the time comes. They lie comfortably on your face. They often lose facial hair. The filter is torn by facial hair, and then tiny bits of filter relentlessly tickle your nose. I'm not sure if we humans have solved this problem. Great filter for a great mask system. I've been wearing them 8+ hours a day, 40 hours a week since January.
