Objective

To evaluate the efficacy of the Defend 1050 / Pro XL on reducing airborne Staphylococcus epidermidis bacteria, a surrogate for methicillin-resistant Staphylococcus aureus (MRSA).

Methodology

The test environment was a 30 m³ test chamber, located in the Novaerus microbiology laboratory. During the testing, the Defend 1050 / Pro XL device was placed inside the chamber at the centre, with the air inlet facing towards the door of the chamber. The Defend 1050 / Pro XL device was tested at maximum airflow, speed setting 5. The test chamber was controlled for temperature and humidity at 77ºF and 50% relative humidity.

Results

The Defend 1050 / Pro XL achieved a microbial cell reduction of 99.94% of Staphylococcus epidermidis, a surrogate for methicillin-resistant Staphylococcus aureus (MRSA), within 15 minutes of operation.
