Can a homemade pop filter work as well as a bought one?

It is eleven at night, the voice-over for tomorrow's video is half done, and every "P" in "probably the best part" lands in the headphones as a dull thump. The shops are shut. In the drawer there is a pair of old tights, and somewhere in a cupboard an embroidery hoop from a hobby that did not last. The question is whether those two things can do the job of a $28 accessory, or whether the result will be a muffled voice and a wasted evening.

Short answer: yes, a homemade pop filter built the right way stops plosives about as well as a bought nylon one, because it uses the same material on the same kind of frame. Sound On Sound's Paul White wrote in 2005 that you can make one from old nylon tights and a wire coat hanger, and Wikipedia's entry on pop filters calls an improvised one made from tights over an embroidery hoop, a kitchen sieve or a bent hanger "functionally identical" to the professional units. Where the DIY version loses is everything around the screen: the clamp, the gooseneck, how it holds position, how it looks on camera. And there is one way to build it that does real damage to your sound, so read the fabric section before you cut anything.

If you are not yet sure you need a pop filter at all, or whether the foam cover that came with your mic is enough, read do you need a pop filter, or is a foam windscreen enough first. That page explains the mechanism and the bought options in depth. This one is for the reader who has already decided to stop the thumps and wants to know whether a makeshift pop filter will hold up.

What your homemade filter has to get right

A plosive is a jet of air. Say "puh" with your palm a few centimetres from your lips and you feel it; say "ah" and you feel almost nothing. That jet hits the mic's diaphragm and shoves it far harder than your voice does, and the result is a low thud or, at worst, a crackle of distortion.

A pop filter does two things to that jet, and your DIY build has to do both:

1. Break it up. A fine mesh turns the fast, coherent puff into turbulence. Paul White's description in Sound On Sound is that the air "breaks up, becomes turbulent, and loses its coherence".
2. Leave a gap of still air behind the mesh. White is explicit that the shield must sit a couple of inches in front of the capsule. Whatever gets through the mesh spreads out across that gap and arrives as a breeze instead of a punch. Wikipedia gives the usual distance as 5 to 15 cm (2 to 6 in).

Sound passes through a thin mesh almost untouched. A jet of air does not. That difference is the whole trick, and it is why the material and the gap matter far more than who made the frame.

How to make a pop filter from tights and a hoop

This is the build that works best, because an embroidery hoop gives you a rigid, flat, round frame of the same size as most bought filters, and the two rings clamp the fabric tight without glue.

DIY POP FILTER, HOOP VERSION

Frame        embroidery hoop, about 15 cm (6 in) across
Mesh         sheer nylon tights or stockings (the thinnest pair you have)
Fixing       the hoop's own outer ring + its screw
Mount        wire coat hanger, or a spare clamp / large binder clip
Tools        scissors, pliers for the hanger

Place it     5 to 10 cm in front of the mic grille
Check        palm test: "puh-puh-puh", you should not feel a jet behind the screen

Step by step:

1. Cut a section of leg about 30 cm long from the tights, below the knee where the knit is most even. You get a tube.
2. Pull the tube over the inner ring so that one layer covers the front face and one layer covers the back face. Now you have two layers with the thickness of the ring between them. That is the same idea as the Neumann PS 20 a, which, per Neumann's product page, uses gauze on both sides of a 20 cm frame. Sound On Sound describes the same two-layer idea: whatever gets past the first layer is mopped up by the second.
3. Press the outer ring over it and tighten the screw until the fabric is flat like a drum skin. Wrinkles are fine acoustically; slack is not, because loose fabric flaps when the air hits it.
4. Trim the excess fabric behind the screw, or tie it off with a rubber band so it does not hang in front of the mic.
5. Make a mount. Unbend a wire coat hanger, twist one end tightly around the hoop's screw, and wrap the other end two or three turns around the mic stand or boom arm below the mic. Bend the wire until the hoop hangs vertically 5 to 10 cm in front of the grille.

The one rule for the mount: the hoop must not touch the microphone. Attach it to the stand, not to the mic body. A screen touching the mic passes every bump and tap of the wire straight into the capsule, a point Wikipedia's pop filter entry makes too.

If you have no hoop, a ring of coat hanger wire works as the frame. It is harder to get round and flat, and the fabric tends to slide, so tape it at a few points. A kitchen sieve also works as a frame, as Wikipedia notes, but only with tights stretched over it: the sieve is the hoop, the nylon is still the filter.

The palm test: check it before you record

You cannot judge a pop filter by looking at it, but you can judge it with your hand.

• Hold your palm 5 to 10 cm behind the screen, where the mic will be.
• Say "puh, buh, tuh" at normal speaking force into the front.
• Without the screen you feel a sharp puff each time. With a working screen you feel a faint, spread-out breath, or nothing.

Then do the second half of the test with a recording. Record the same sentence twice, once without the filter and once with it, at the same distance: "Peter picked a perfect pepper, so stop speaking so softly." Look at the waveform in any recorder (QuickTime's audio recording is enough). The P's without a filter show as tall, fat spikes that stand above the rest of the line. With the filter they should sit at the height of the other syllables. Then listen to the "s" and "f" sounds in both takes. If they are clearly duller with the screen, your fabric is too dense, which brings us to the real risk.

What ruins the highs: dense fabric

A DIY pop filter can also fail in the opposite direction: it stops the pops and takes the top end of the voice with them. The consonants that make speech easy to follow, the "s", "f", "t" and "k" sounds, live in the high frequencies, and dense fabric absorbs high frequencies.

Even commercial nylon screens do a little of this. Sound On Sound notes that nylon-mesh shields cause "a slight dulling of the sound at high frequencies", while metal ones with larger holes have less effect. So the rule for DIY is simple: use the thinnest material that still stops the jet, never the thickest one you can find.

For tights, the number on the packet tells you how thick the yarn is. Denier is the weight in grams of 9,000 metres of thread (see the Wikipedia entry on textile units), so a lower number means finer yarn. The sheer pair is the one you want. Opaque winter tights, the ones you cannot see through, are the wrong pair. A quick check: hold the stretched screen up to a lamp. If you can clearly see the light and shapes through it, sound gets through too. If it looks like a solid black disc, expect duller consonants.

The sock deserves its own line, because it is the quickest makeshift pop filter to improvise and the worst one. It sits directly on the grille, so there is no gap of still air for the broken-up jet to spread across. Sound On Sound says even proper foam windscreens are no match for a full-on plosive and absorb enough high frequencies to make the sound noticeably duller. A sock is thicker than foam and has the same problem.

Emergency fixes when you have nothing at all

The pencil trick. Fix an ordinary pencil vertically across the centre of the mic grille with a rubber band. Production Expert describes it as a way of disrupting the airflow before it reaches the diaphragm. It splits the jet in two at the capsule. It does not create an air gap, so it is weaker than a real screen, but it costs nothing and takes ten seconds.

The finger trick. Same source: hold your index finger vertically in front of your lips, as if saying "shhh", while you speak. It redirects the puffs sideways. The tip is pitched at a session where someone forgot the pop filter: it rescues a line or two, but holding it through a whole podcast is tiring.

Speak past the mic, not into it. This free fix can beat everything above. The jet from a "P" travels straight forward from your mouth. Turn the mic 15 to 30 degrees so you speak across it, or set it slightly above or below mouth height, and the jet misses the diaphragm while your voice still reaches it. Headset mics usually sit beside the mouth rather than in front of it, which keeps them mostly out of the jet's path.

Back off a little. The jet loses force quickly over distance. If you are 3 cm from the mic, moving to 10 cm can solve the problem on its own. Go much further than 15 to 20 cm in an untreated room, though, and you trade pops for echo.

Homemade vs bought: what the money actually buys

Here is what bought pop filters cost as of October 2026, from the makers' own stores or a large US retailer:

Look at what changes between the rows. The screen itself does not get much better between $14 and $85. What you pay for is:

• A gooseneck and clamp that hold the screen at exactly the same spot every session. A coat hanger drifts every time you brush it.
• A metal screen, at the top end, which wipes clean and, per Sound On Sound, dulls the highs less than nylon does.
• Looks. On a stream or a video call where the mic is in shot, a hoop with a knotted stocking reads as improvised. That matters for some people and not at all for others.

Before buying anything, check the box your mic came in. Some mics include a filter: Rode lists "1 x Pop Filter" in the box for the NT-USB+, for example.

Paul White reached a blunt conclusion back in 2005: bought shields had become cheap enough that making your own "really isn't worth the effort". That holds if you record often. It does not hold at eleven at night with the shops shut.

So the honest verdict: for a one-off session tonight, build the hoop version and do not think twice. If you record every week, spend the $14 to $28, because by then you are paying for a clamp that stays where you put it, not for a better mesh.

When a pop filter will not fix what you hear

A pop filter fixes one problem: air hitting the capsule. It does nothing for sibilance (Wikipedia notes pop filters do not appreciably affect hissing "s" sounds; that is a de-esser's job), and nothing for the three things that make home recordings sound amateur.

• The room. Hard walls send your voice back into the mic a few milliseconds late, which reads as a hollow, distant sound. A pop filter cannot help, because the reflections arrive from behind and around it. If that is your problem, whether you need a vocal booth or a reflection filter is the right next read.
• The mic itself. A very cheap mic with a narrow, boxy tone stays narrow and boxy behind any screen. If you are deciding whether to upgrade, which budget microphone is worth buying covers what to buy and how to get more from it.
• Distance. A laptop or webcam mic half a metre away does not pop at all, so a pop filter for it is wasted. The problem there is too much room and too little voice, which why your mic sounds muffled or far away goes through.

This is where software earns its place, and where TunedMic fits for some readers. TunedMic is a Mac app that adds a virtual microphone tuned to your voice: you read a short passage aloud for about a minute (the Sound Check), it takes more than 30 measurements of your voice, mic and room, and builds voice profiles from those measurements, with optional manual controls for noise, room echo, clarity and loudness. Zoom, Discord, OBS, Telegram or any other app that lets you pick a mic then hears the processed voice.

Be clear about what it does not do. TunedMic works on the sound after your mic has captured it, so it is not a replacement for a pop filter. A pop that drove the mic into distortion is already baked into the signal before any software sees it. The order that makes sense is the physical fixes first (screen, angle, distance), then software for the room, noise and tone that no screen can touch. And it is Mac-only: it needs a Mac with Apple silicon (M1 or newer) and macOS 14 or later. There is no Windows version, and Intel Macs are not supported.

If you want to see what that processing involves before deciding, the 38-second video on the home page walks through the minute of reading aloud that sets it up, and the free 7-day trial lets you hear the result on your own mic.

Quick answers

How far should a DIY pop filter be from the mic? 5 to 10 cm in front of the grille, with your mouth another 5 to 10 cm in front of the screen. Closer than 3 cm to the mic and there is not enough air gap.

Does a homemade pop filter work for singing? Yes, the physics is the same. Singers tend to work closer and push more air, so use two layers and make sure the mount is solid; a hoop that sags halfway through a take is the usual failure.

Can I use one layer of tights? Yes. Two layers with a gap are better at stopping a hard "P". If one layer still lets a jet through in the palm test, add the second layer rather than switching to thicker fabric.

Is a metal mesh kitchen strainer a pop filter on its own? Wikipedia lists a sieve only as a frame for tights, so treat it that way and stretch nylon over it. Then run the palm test: if a jet still reaches your hand, the nylon layer is doing too little.

Will a pop filter reduce background noise? No. It stops air, not sound. For a noisy room, how to stop your mic picking up background noise is the guide.

Your next step

Tonight: cut the leg off the thinnest pair of tights you have, stretch it over both faces of the hoop, hang it 5 to 10 cm in front of the mic on a bent hanger that does not touch the mic body, and run the palm test. Then record "Peter picked a perfect pepper" with and without it and compare the spikes. If the P's are flat and the S's are still crisp, you are done for the price of nothing.

If the pops are gone but the voice still sounds thin, hollow or noisy, the screen has done its part and the rest is room and tone. On a Mac, the TunedMic free 7-day trial lets you work on that part with your own mic, with every feature and no card or account. After that it is $19 once; the details are on the pricing page.
