Objective
To assess the performance of the Defend 1050 in removing aerosolised Human parainfluenza type 3 (HPIV3) (renamed human respirovirus 3), a surrogate for Measles virus.
Methodology
The impact of Novaerus Defend air purifier on aerosolised HPIV3 (strain MK-3) was conducted in a 28.5 m3 environmental testing chamber. The test chamber was preconditioned to 20 ± 3 °C and 55 ± 5% relative humidity. During testing, the chamber air handling unit was shut down, which reduces the number of air changes to as close to zero as possible.
Results
The results achieved during the testing show that the Defend 1050 was able to reduce the concentration of HPIV3 by 99.87% in 20 - 30 minutes.
