Case Study: American PAPR LLC achieves NIOSH-approved 99.97% filtration PAPR with Xometry

American PAPR Creates NIOSH-approved Respiratory Device

American PAPR LLC, a Brooklyn-based startup formed to tackle PPE shortages during the COVID‑19 surge, designed the FELIX100 and FELIX200 powered air purifying respirators that deliver 99.97% particulate filtration and sought rapid NIOSH approval. The team faced a tight timeline and a lean-budget requirement to source custom, high‑precision aluminum housing panels and other components domestically, and turned to Xometry for on‑demand CNC machining and onshore supply chain support.

Xometry CNC‑milled the critical housing panels, leveraging its American supplier network to provide competitive pricing, faster lead times, manufacturing guidance, and quality controls needed for certification. As a result, Xometry-produced parts fit without gaps, improved visual and dimensional quality, supported the FELIX200’s NIOSH approval, and enabled hundreds of just‑in‑time shipments that lowered cost, consolidated suppliers, and reduced American PAPR LLC’s capital‑investment risk.
