Objective

To assess the performance of the Defend 1050 / Pro XL in removing aerosolised Mycobacterium smegmatis, a surrogate for Mycobacterium tuberculosis.

Methodology

The impact of the Defend 1050 / Pro XL air purifier on aerosolised M. smegmatis was conducted in a 30 m3 environmental testing chamber. The test chamber was preconditioned to 68 ± 5 °F and 55 ± 5% relative humidity. These conditions were maintained throughout the test and control runs. Prior to each run, the test chamber was decontaminated by scrubbing the walls and surfaces.

Results

The results achieved during the testing show that the Defend 1050 / Pro XL was able to reduce the concentration of M. smegmatis artificially aerosolised by 95% within the first 15 minutes and this rose to 97% after 30 minutes of A/C operation.
