Answer
The air filtration units, purchased by the Education Authority, utilise a H14 HEPA filter, a H14 filter typically has a described efficiency of 99.995%. The efficiency of HEPA filters is measured in MPPS (most penetrating particle size), which is the particle size that is most likely to navigate its way through a filter that represents the lowest efficiency of the filter. MPPS is generally between 100 and 250 nanometers.
