Respiratory Filter Testing

Respiratory filters provide an effective barrier to prevent cross-contamination between patients, respiratory systems, respiratory and anesthesia equipment, and the clinical environment. Their use is widely recognized as beneficial and recommended by many anesthesia societies. They are used extensively throughout hospitals, particularly in operating theaters, intensive care units, pulmonary function units and respiratory care units.

Respiratory filter testing involves evaluating the effectiveness of filters used in devices such as air purifiers and ventilation systems, or those used in personal protective equipment such as masks. The main goal is to confirm they are capable of removing harmful particles from the air. These particles could be solid particles like dust, pollen, mold spores or liquid droplets from aerosols.

STEMart provides comprehensive and reliable respiratory filter testing services to evaluate the effectiveness of filters used in respiratory devices to ensure they are removing harmful particles, gases, and other contaminants from the air.
