What is a pop filter?

What is a pop filter: The pop filter is a microphone accessory used in the audiovisual field to prevent unwanted noise. Even if there are several models, the fact remains that they all fulfill the same function. Let’s discover the essentials to know about this very useful tool in the field of sound.

The pop filter to eliminate plosives

The anti – pop filter limits unpleasant plosives and prevents contact between saliva and the microphone . Indeed, the popping noises that are usually referred to as plosives come from words containing hard consonants . These are among others “p”, “b”, “t” or “f” to name a few.

Harsh consonants can be a problem especially if you are using a very sensitive microphone such as ribbon microphones. The sudden burst of air that their pronunciation causes can damage the microphone. This large amount of air suddenly hits the microphone capsule, creating what are called “pops”, noises that are unpleasant to hear.

It is to overcome this problem that pop filters were created. Simply place them at the end of your microphone so that these noises are hidden during the recording of music for example.

The pop filter to limit saliva

The pop filter prevents a singer’s saliva from coming into contact with the microphone when recording. When you have a recording studio, and you have enough productions to do, cleaning and disinfecting a microphone can be tedious. The task is even more difficult if several singers use the microphone in very short time. The pop filter solves this problem and allows you to extend the life of your microphone.

The different types of pop filter

There are mainly two types of pop filter namely: nylon mesh pop filter and fine metal pop filter.

The nylon mesh pop filter is used most often in professional recording studios. The particularity of this type of filter lies in its efficiency and its affordable price. You can buy a nylon mesh pop filter from around 25 euros . However, for many sound professionals, the nylon mesh pop filter reduces high notes and diminishes the clarity of the recording.

This is why in recent decades there has been a proliferation of fine metal pop filters on the market. They give a more precise sound and limit unwanted noise as much as possible. In addition, they are easy to clean after several uses. To have this very practical accessory, you will have to pay the tidy sum of 80 euros on average. This price is quite reasonable, considering the benefits you can get from it.

Criteria for choosing a pop filter

Before paying for the purchase of a pop filter for your studio, you must check that the model offered to you meets certain criteria.

The size

You can choose a filter whose size is proportional to your microphone for optimal rendering. You can also opt for a model a little larger than your microphone. This will avoid discrepancies, especially if your singers, in this case rappers, move a lot during recordings.

The material of manufacture

You have to choose between nylon mesh pop filters or thin metal ones. Note that thin metal pop filters have a longer lifespan than the former. However, you should consider your budget and usage before opting for either of these categories. If you are on a budget, it is better to opt for a durable pop filter.

The type of attachment

Most pop filters have a clip-style attachment. It allows you to attach them to the stand of your microphone very easily. Take into account the size of the clip and the thickness of your microphone stand before making your choice.
