http://blueyetipopfilter.com/go A pop filter helps you remove pops from your recording. Pops are formed when the microphone accumulates quick bursts of air formed when speaking plosives. Consonants such as P, B, T or D are regarded as plosives (ex-plosives). Pop filters generally function as a screen to break up those bursts of air simply before they reach the microphone. They are clamped into the microphone stand NEVER on the microphone itself to be able to lessen the possibility of the pop filter taking in noises when the microphone is tapped or shifted.
