http://blueyetipopfilter.com/go A pop filter helps you get rid of pops from your audio. Pops are created when the mic picks up rapid blasts of air created when speaking plosives. Consonants such as P, B, T or D are regarded as plosives (ex-plosives). Pop filters fundamentally perform as a screen to dissolve those blasts of air only before they hit the mic. They are clamped into the mic stand NEVER on the mic itself as a way to lessen the possibility of the pop filter absorbing noises when the mic is tapped or shifted.
