The filtration efficiency of the most penetrating particle size (MPPS).
Is an abbreviation of Efficiency Particulate Air.
Is an abbreviation of High Efficiency Particulate Air.
Is an abbreviation of Ultra Low Penetration Air.
Refers to particle separation of a specified size of particle.
Is a way of categorizing the particle content in the indoor air depending on the activity being conducted.
