F3 filters are the premium option for use with our various reusable Mesh Face Masks (e.g. #59635, sold separately). F3 filters provide up to 50% better breathability than the standard F1 filter. Composed of five unique layers of protection, the F3 features an electrostatic filter to capture small particulates down to 0.1 micron and an active carbon layer to greatly reduce odors and fumes. Providing up to 99% filtration and the best breathability, the F3 filter is a favorite filter for woodworking, construction, lawn care, power sports and more.
