What is a pop filter?

A pop filter is a circular mesh or nylon screen placed between your microphone and your mouth. Its job is to reduce unwanted “popping” sounds caused by plosive consonants like P and B. When you say these sounds, bursts of air hit the microphone’s diaphragm, creating harsh noises.

By diffusing this airflow, the pop screen acts as a barrier that keeps your recordings clean and professional. For voice actors, understanding what is a pop filter is key to producing crisp audio that clients will actually want to use.

What does a pop filter do?

So, what does a pop filter do beyond reducing plosives?

  • It disperses airflow without affecting sound waves.

  • It balances audio by minimizing low-frequency spikes.

  • It improves vocal clarity, helping you sound smooth and consistent.

For voice actors, this means fewer retakes, cleaner auditions, and recordings that sound studio-ready.

A pop filter contributes to overall audio balance by minimizing low-frequency spikes to maintain consistent airflow, helping you improve your audio. So, understanding what does a pop filter do enables you to prepare the best possible acoustic environment for your recordings. 

What are the different types of pop filters?

There are several types of pop filters, and the best choice depends on your setup. Different types of pop filters are available in multiple shapes, sizes, and materials. A microphone filter can be circular or semicircular, angled over the grille, while others have a wraparound rectangular style for complete coverage. A microphone filter is also available in three different pop screen material options.

types of pop filters

1. Foam Windscreens: These fit directly over the microphone. They’re lightweight, affordable, and great for outdoor or portable recording. However, they don’t filter plosives as effectively as other options.

2. Nylon Mesh Pop Screens: The most common option in home studios, these microphone filters attach in front of your mic. They’re inexpensive, easy to use, and perfect for everyday voice-over work.

3. Metal Mesh Filters: Professional-grade pop filters made of metal allow a wider frequency range to pass through. They’re durable and ideal for high-fidelity recordings like audiobooks, commercials, or narration.

How to choose the right pop filter 

When selecting the best types of pop filters for your needs, consider the following:

  • Filter Type: Decide between foam, nylon, or metal mesh based on your recording environment and audio needs.
  • Mic Compatibility: Ensure the pop filter fits your microphone type—condenser, dynamic, or lavalier.
  • Adjustability: Look for a microphone filter with flexible goosenecks or adjustable arms for easy positioning.
  • Material Quality: Higher-quality materials often offer better sound diffusion and last longer.
  • Filter Density: Multiple layers of mesh or foam can improve plosive reduction without muffling your voice.
  • User Reviews: Insights from other voice actors on the best types of pop filters can guide your decision.
  • Extra Features: Consider options like microphone filters with detachable screens, anti-vibration mounts, or compatibility with shock mounts.

FAQ's

A pop filter reduces plosive sounds—like the strong bursts of air from P and B consonants—that can distort recordings. It disperses airflow before it hits the microphone, ensuring cleaner, smoother audio.

Yes, pop filters are highly effective at reducing plosives and improving audio clarity. While they don’t eliminate all unwanted noises (like room echo or breathing), they’re essential for professional-sounding voice recordings

While a pop filter won’t fully eliminate inhales and exhales, it can soften the impact of breath bursts that hit the mic. To reduce breathing noise further, adjust mic technique, practice breath control, or edit out breaths in post-production.

Yes. A common DIY pop filter uses a piece of foam or mesh that’s attached to a stand. While DIY options can work in a pinch, investing in a proper pop screen is better long-term for durability and consistent quality.

"Nothing beats a good pop-filter and no voice actor should record without one! The mesh can prevent plosives from reaching the mic capsule by effectively dispersing your breath. Pros recommend double-layered pop filters since they work better than single-mesh or a punched-metal one."
