The SDI Diagnostics AstraGuard Bacterial/Viral Filter Kits with Kushion Klip are high-efficiency, single-patient disposable testing mouthpieces designed to maximize infection control during pulmonary diagnostics. Engineered by SDI Diagnostics specifically for their Astra series spirometers, this convenience configuration pre-bundles a protective barrier mouthpiece together with a soft, foam-padded Kushion Klip nose clip inside a single wrapper. This setup eliminates the need to source or open separate accessory packs, accelerating point-of-care patient setups.
