The Technostat filter is for use with the Laerdal Pediatric Pocket Mask, allowing it for ventilation and user protection. Technostat T-150(+) filter has low air resistance and high dust-holding capacity. The Technostat filter has been tested to a penetration of 1,8% @ 0.6 µm NACL unloaded. The viral filtration efficiency test proved that 99.99% of aerosol particles >2.7 µm were filtered and the bacterial filtration efficiency test proved that 99.99% aerosol particles >2.7 µm were filtered. The filter is two-sided.
