What is a Pop Filter?

A pop filter is a screen placed in front of a microphone to reduce plosive sounds that occur during speech or singing. It is typically made from a thin layer of mesh or fabric stretched across a circular frame and mounted on a flexible arm attached to a microphone stand.

When a performer pronounces plosive consonants such as “P” and “B,” a burst of air can strike the microphone diaphragm and cause a popping sound in the recording. A pop filter helps disperse this burst of air before it reaches the microphone.

Pop filters are commonly used in studio vocal recording, podcasting, voiceover work, and streaming. In addition to reducing plosives, they also help maintain consistent microphone distance and protect the microphone from moisture produced during speech or singing.
