The SDI Diagnostics PulmoGuard Filter Kits with The Klip Nose Clip are high-efficiency, single-use respiratory safety packages designed to optimize clinical workflow during pulmonary function testing (PFT). Developed by SDI Diagnostics, this specific setup pairs a pleated electrostatic PFT barrier filter with a disposable, lightweight "Klip" style nose clip inside a single hygienic wrapper. This eliminates the need to open separate accessory packs, ensuring rapid patient setup during forced expiratory maneuvers.
