FLTR's general use face masks, FLTR95 sealing face masks, and NIOSH-approved N95 masks are currently made exclusively in China.

To ensure quality of the products we sell, FLTR has a world-class factory selection and auditing process, and an ongoing Quality Assurance program that includes in-house product testing, inline quality inspections, final inspections of all orders performed by FLTR's own QC, and independent third-party testing of products to the ASTM international standard. 

• FLTR General Use Masks are tested to ASTM F2100-2019 Standard Specification for Performance of Materials Used in Medical Face Masks, Level 1.
• FLTR95 Sealing Face Masks and N95 Respirators are all tested to the National Institute for Occupational Safety and Health (NIOSH) standard 42 CFR Part 84.

This ensures that FLTR products are manufactured to meet the strict standards that our customers demand.
