Flo Mask medical grade filters are proudly made in the USA, filtering down to 0.1 micron. Each filter is individually bagged and sealed at the factory with a 5 year shelf life.

Replacing Filter

For peak filtration efficiency and breathability, we recommend changing the filter after 8 hours of continuous use and storing the mask in the microfiber pouch when not in use.
