Aspire AF Mesh Coil: What This Replacement Coil Is

The Aspire AF Mesh Coil is a replacement heating head for refillable vape tanks. It is sold as a consumable accessory, which means there is no battery, no tank and no e-liquid in the pack. What you receive is a compact atomiser coil built from a stainless steel mesh sheet wrapped around an organic cotton wick, housed in a metal and plastic shell that seats into a compatible Aspire tank. When the coil wears out, you swap it for a fresh one and carry on using the same tank and the same battery device.

This listing covers a family of three variants. They differ in resistance and in the wattage window each one is designed to run in, so the variant you choose should follow the way you like to vape rather than a guess. Always check the compatibility line on the product page before you order. Coil heads are specific to the tank they were designed for, and a head that looks similar is not guaranteed to seat or seal correctly in a different model.

Aspire is an established hardware maker whose tanks and pod systems have been sold in the UK for years, and the company has used mesh coils across several of its sub-ohm and mouth-to-lung designs. If you already own an Aspire tank and are partway through your last coil, this is a straightforward re-order. If you are new to refillable vaping, the coil is the part of the setup you will buy most often, so it is worth understanding what you are paying for and why it wears out.

Because single-use disposable vapes have been prohibited for sale in Great Britain since June 2025, a refillable tank with replaceable coils is now the main route for people who want a reusable setup, and the coil is the running cost to budget for. It is a small item, but it has a large influence on flavour, vapour volume and how smooth or harsh each puff feels.

Key points at a glance:

• Type: replacement mesh atomiser coil, sold as a consumable accessory
• Variants: three, differing in resistance and recommended power range
• Wick: cotton, which must be primed with e-liquid before first use
• Typical life: roughly one to three weeks of regular use, depending on e-liquid and power
• Not included: battery device, tank, e-liquid or charger

The rest of this guide explains how mesh coils work, what to expect from each power band, which e-liquids suit them, how to fit and prime the coil properly, and how to fix the usual problems when something tastes or feels wrong.

How Mesh Coil Technology Works

A traditional coil is a length of round resistance wire wound into a spiral and threaded through a cotton wick. The wire touches the cotton at a limited number of contact points, so heat is concentrated in a small area. That works, but it can create hot spots where liquid vaporises unevenly, and it can leave other parts of the wick under-used.

A mesh coil replaces the spiral with a flat sheet of woven or perforated metal, usually a grade of stainless steel such as 316L. The sheet is folded or rolled into a shape that lines the inside of the coil head, with the cotton pressed against its back. Because the sheet has many tiny openings and a much larger surface area than a single wire, it touches far more of the cotton at once.

That design brings several practical effects:

• Faster ramp-up: a thin sheet with a big surface area heats quickly, so vapour appears almost as soon as you press the button or start your draw.
• More even heating: heat is spread across the whole wick instead of a few contact points, which reduces the chance of one patch scorching while another stays cool.
• Lower resistance in a small package: a wide conductive sheet has very little resistance compared with a long thin wire, so mesh coils can reach low ohm values without needing a bulky coil head.
• Consistent flavour: a more uniform temperature tends to give a steadier flavour from the first puff to the last on a tank fill.

There are trade-offs worth knowing about. Mesh draws liquid quickly, so the cotton behind it has to keep up. Very thick, high-VG liquids can wick slowly, and if the wick runs short mid-puff you will get a dry, burnt taste. The solution is to match the liquid thickness to the coil and not to run the power higher than the coil is rated for. Mesh is also thin, so a burnt coil is harder to recover than a thicker round wire coil; once the cotton has scorched, a fresh head is the only reliable fix.

Stainless steel mesh is commonly compatible with temperature control modes on devices that offer them, but not every coil is rated for that, so check the markings on the pack before switching modes. For most people, running the coil in plain wattage mode inside the printed range is simpler and safer.

The AF mesh design follows these principles. Its job is to deliver steady vapour and clear flavour from a small replaceable head, while keeping the tank itself unchanged from one coil to the next.

Performance and Vapour Delivery

A coil does not have a puff count in the way a disposable does. Its output is governed by the power you feed it, the airflow of the tank and the liquid you use, and its life is measured in days or millilitres rather than puffs. That said, you can set realistic expectations by looking at how the three variants are likely to behave, because resistance sets the power band and the power band sets the experience.

As a general guide, mesh coils fall into these bands. Treat the figures as indicative and always follow the range printed on the coil or its packaging:

• Low resistance, around 0.15 to 0.25 ohm: designed for direct-to-lung inhaling at higher power, commonly in the region of 40 to 70 watts. Big vapour, warm and airy draw, high liquid use.
• Mid resistance, around 0.3 to 0.5 ohm: a flexible band, typically 20 to 40 watts, suitable for a looser mouth-to-lung draw or a lighter direct-to-lung inhale. Balanced vapour and moderate liquid use.
• Higher resistance, around 0.6 ohm and above: intended for tighter, restricted draws at lower power, often 12 to 25 watts. Smaller clouds, a cooler vape and noticeably lower liquid use.

Within a family of three, you should expect the variants to sit across these bands. The variant selector on the page shows which is which, and it is worth reading before you buy rather than after.

In use, the mesh design means vapour starts quickly and holds a consistent temperature through a long draw. You should not need to hold the fire button for a second before anything happens, and the last few seconds of an inhale should taste much like the first. Throat hit is a function of nicotine strength, PG content and power, not the coil alone, but because mesh produces so much vapour per watt it can feel stronger than a round-wire coil at the same setting.

Liquid consumption is the figure many new users underestimate. As a rough rule of thumb, higher-wattage mesh setups use several times more liquid per puff than a restricted mouth-to-lung setup, and a coil in the lowest resistance band can empty a small tank quickly. If you are filling a 2ml tank, expect to refill more often at the low end of the resistance range, and plan your day accordingly. As a loose guide, many people get through somewhere between 30 and 60ml of e-liquid on a single coil before flavour fades, though heavy use, sweet liquids and high power all shorten that.

Performance also depends on a correct prime, a clean tank and a battery that can deliver the current the coil asks for. Those points are covered in the power and troubleshooting sections below.

Flavour Delivery and Which E-Liquids Suit It

This is an accessory, so the three variants in the family are not flavours. They are resistance options. The flavour you taste comes entirely from the e-liquid you put in the tank, and the coil's job is to vaporise that liquid cleanly. A good mesh coil is a neutral, accurate delivery system: it should present the liquid's flavour without adding a metallic or burnt note of its own.

Mesh coils have a reputation for crisp, defined flavour because the even surface heating avoids overcooking the liquid in one spot. That tends to show most clearly with the following kinds of e-liquid:

• Menthol and mint: cool profiles such as peppermint, spearmint and menthol ice come through sharp and clean.
• Berry and ice blends: blue raspberry, blueberry ice and mixed berry liquids keep their brightness.
• Tropical fruit: mango, pineapple and passion fruit blends carry well with a warm, steady draw.
• Soda and cola: fizzy, citrus-led profiles benefit from the quick ramp-up.
• Lemonade and citrus: sharp top notes survive better when the temperature is stable.
• Tobacco and nutty blends: subtler profiles show more depth at moderate power than at the top of the range.
• Dessert and custard: these work, but see the note below about sweeteners.

Sweet liquids deserve a specific warning. Sugars and sweetener compounds in dessert, candy and bubblegum e-liquids caramelise on the mesh and cotton, forming a dark residue that dulls flavour and shortens coil life. If you vape these regularly, expect to replace the coil sooner than you would with fruit, menthol or tobacco liquids, and keep the power towards the middle of the printed range.

Changing flavour is straightforward but not perfectly clean. Cotton holds on to the last liquid it soaked up, so a switch from heavy menthol to a delicate fruit can leave a ghost of the old flavour for a few tank fills. If you want a completely fresh taste when you change profile, rinse the tank, dry it properly and fit a new coil. Many people dedicate one coil to one flavour family for this reason.

Liquid thickness matters too. High-VG liquids produce more vapour but wick slowly, and a mesh coil in the lowest resistance band will happily out-run a thick liquid. A 70/30 VG/PG blend is a common choice for the lower resistance variants, while 50/50 suits the higher-resistance, tighter-draw options.

Design and Build Quality

The coil head is a small, self-contained part, and build quality is easy to judge from the moment you open the pack. It is made up of a metal outer shell, a base with sealing rings, the stainless steel mesh element, a cotton wick and one or more wicking inlets on the side or base that let liquid from the tank reach the cotton.

When your order arrives, a quick inspection catches most defects:

• Mesh shape: the mesh should sit evenly against the cotton with no obvious creases, gaps or exposed edges.
• Cotton: there should be no loose fibres hanging out of the shell and no signs of dry brown staining before use.
• Sealing rings: the silicone O-rings should be intact, seated in their grooves and free of cuts.
• Markings: the resistance and the recommended wattage should be printed on the coil shell or its packaging, and they should match the variant you ordered.
• Packaging: the pack should be sealed and undamaged, with batch information and a clear compatibility note.

Fit is where small tolerances matter. A coil that is not fully seated, or a damaged O-ring, causes leaks and gurgling, so push or screw the head into place exactly as the tank instructions describe, without forcing it. Over-tightening can crush the seal or strip the thread, and under-tightening leaves an air gap that lets e-liquid seep into the base.

Materials are an important point. Stainless steel mesh, organic cotton and silicone seals are common and well understood in vaping hardware. The shell is built to survive being screwed in and out of a tank, but it is not designed to be cleaned and reused indefinitely. Treat it as a wear item.

As with any popular accessory, counterfeits exist across the vape market. Buying from an established UK retailer, checking that the packaging matches what you have had before, and being wary of prices far below the usual range all help. If a coil arrives with mismatched markings, damaged seals or a suspicious smell, do not use it. Contact the retailer and keep the packaging, because that is what you will need for a return or exchange.

The coil is light, small and easy to store. Keep spare heads in their original packaging, away from heat and direct sunlight, and out of reach of children and pets, since the cotton and the residue left on used coils are not safe to handle casually.

Power, Batteries and Charging

The coil has no battery of its own and does not charge. It draws power from whichever device it is attached to, which means the quality and capacity of that battery has a direct effect on how the coil performs. If your vape feels weak, flavourless or inconsistent, the battery side deserves as much suspicion as the coil.

Resistance and power set the electrical demand, and the numbers are simple enough to check. Voltage equals the square root of power multiplied by resistance, and current equals power divided by voltage. A few worked examples show why the low resistance variants need a capable battery:

• 0.2 ohm at 60 watts: about 3.5 volts and roughly 17 amps drawn from the battery.
• 0.3 ohm at 30 watts: about 3.0 volts and roughly 10 amps.
• 0.6 ohm at 20 watts: about 3.5 volts and roughly 5.8 amps.

Devices with removable cells must use a battery rated for the current the coil will draw, with a margin to spare. If you run a low-resistance coil at higher power on a cell with a low continuous discharge rating, it will sag, overheat or trip protection. Use only cells specified by your device maker, keep the wraps undamaged, never mix old and new cells, and carry spares in a plastic case rather than loose in a pocket with keys or coins.

Devices with a built-in battery are simpler: charge them with the supplied cable and a sensible power source, not a cheap unbranded adapter. Most modern devices charge over USB-C. Typical charging currents are in the one to two amp range, and a full charge for a mid-capacity device usually takes in the region of an hour or two, but the device's own manual is the authority here. Do not leave a battery charging unattended overnight, do not charge it on a soft surface where heat can build up, and stop using any cell that is swollen, hot, dented or leaking.

A fresh coil needs a little time to settle in. Start at the low end of the printed wattage, take a few gentle puffs, then raise the power in small steps until flavour and warmth feel right. Running a new coil at full power straight away is one of the most common ways to burn the cotton in the first day.

When batteries reach the end of their life, do not put them in household bins. Take them to a battery recycling point, such as the collection boxes at many supermarkets and household waste recycling centres. Vape shops and retailers that sell electrical goods are also expected to offer take-back arrangements for small electrical items, so ask when you buy.

Nicotine Strength Guidance

The coil does not contain nicotine, but the strength of the liquid you pair with it changes the experience more than almost any other choice. In the UK, nicotine e-liquid is capped at 20mg/ml, which is 2 percent, and bottles are limited to 10ml for nicotine-containing products. Refillable tanks sold with nicotine liquid are limited to 2ml capacity. Those rules apply however you vape, and they are the reason single-use devices and refill setups in the UK all sit within the same 20mg ceiling.

The best way to choose strength is to match it to your coil variant and your power level:

• Lower resistance, higher power, bigger inhale: use a low strength, typically 3mg to 6mg of freebase nicotine, or a low-strength nicotine salt. Each puff delivers a lot of vapour, so a little nicotine goes a long way.
• Mid resistance, moderate power: 6mg to 12mg is a common starting range, depending on whether you inhale into your mouth first or straight to the lung.
• Higher resistance, low power, tight draw: nicotine salts at 10mg to 20mg are the usual match, because each puff is small and a higher concentration is needed to feel satisfied.

Freebase nicotine is harsher on the throat at higher strengths and suits lower-strength, higher-power setups. Nicotine salts are smoother at higher strength and are designed for low-power, tighter-draw devices. Using a high-strength salt in a low-resistance coil at high wattage is one of the quickest ways to a harsh, uncomfortable vape, so avoid it.

If you are moving from cigarettes, a stronger liquid in a restricted-draw setup is generally easier to start with, and you can reduce strength over time. If you are moving from a disposable, check the strength you were using, because most were sold at the 20mg ceiling, and a sub-ohm style direct-to-lung inhale at that strength will be far too intense. Drop the strength a long way when you move to low resistance coils.

If you start getting headaches, dizziness, nausea, a racing heart or a very harsh throat, you are taking in too much nicotine for your setup. Lower the strength, lower the power or switch to a higher resistance coil. These products are intended for adults who smoke or already use nicotine. Anyone who does not use nicotine should not start, and smokers who want help stopping can find free local support through NHS stop smoking services.

Who This Coil Is For, and Who Should Skip It

A replacement coil is a narrow purchase. It suits some people very well and is the wrong choice for others, so it is worth being direct about both.

This coil is a sensible fit if you:

• Already own a compatible Aspire tank and need a fresh head.
• Want a cleaner, steadier flavour than you are getting from an older round-wire coil.
• Prefer a refillable setup so you can pick your own e-liquid and strength, and want to move away from single-use devices.
• Are comfortable filling a small tank, priming a coil and checking resistance and wattage before you fire.
• Vape regularly enough that a reusable device and a consumable head make more sense than disposable products.

You should think twice, or skip it, if you:

• Do not own a compatible tank or device. The coil does nothing on its own, and it will not fit tanks it was not made for.
• Want a no-maintenance device. Refillable tanks mean filling, priming, occasional cleaning and replacing heads. If that sounds like a chore, a pod system with a simpler cartridge format may suit you better.
• Use very thick, sweet dessert liquids at high power all day. You will burn through mesh coils faster than someone who vapes fruit or menthol at moderate wattage.
• Do not use nicotine. Nicotine vaping is intended for adults who already smoke or vape, not as a hobby for people who do not use nicotine. If you are under 18 you cannot buy this product at all.
• Are looking for a specific wattage or resistance that is not in the three variants listed. Check the options before you order rather than hoping one will work out.

There is also a middle group worth naming. If you are new to refillable vaping and unsure which variant to pick, start in the middle of the range. A mid resistance coil is more forgiving across liquid types and power settings than either extreme, and it lets you learn what you like before you commit to a low-resistance, high-power style or a very restricted draw.

If you are unsure whether the coil fits your tank, check the model name against the compatibility line on the listing, and contact us before ordering rather than after. Getting the match right first time saves a return and a delay.

How to Fit, Prime and Use the Coil

Fitting a coil takes a couple of minutes, and doing it carefully sets up the whole life of the head. Follow the instructions that come with your specific tank first; the steps below are the general sequence that applies to most refillable tanks.

• Step 1 - Switch off and empty. Turn the device off or take the tank off the battery. Empty any liquid from the tank and unscrew or remove the old coil, wiping the base clean with a dry tissue.
• Step 2 - Check the new coil. Confirm the resistance and wattage markings match what you ordered, and inspect the O-rings and cotton for damage.
• Step 3 - Prime the cotton. Put a few drops of e-liquid directly onto the exposed cotton through the wicking inlets, and drip a little onto the mesh side if it is accessible. Do not flood it, just make sure the cotton looks evenly damp.
• Step 4 - Seat the coil. Fit it into the tank base without forcing, then reassemble the tank so the seals are aligned.
• Step 5 - Fill the tank. Fill with e-liquid to just below the maximum line, keeping liquid away from the central airflow tube. Leave the tank to stand for 5 to 10 minutes with the airflow closed or the device off, so the cotton can soak up liquid through the inlets.
• Step 6 - Fire at low power. Attach the tank, set the power to the lower end of the printed range, and take a few short puffs without inhaling, just to confirm the coil is wet and producing vapour.
• Step 7 - Raise gradually. After a couple of gentle puffs, nudge the power up in small steps until you reach a setting that feels right.

For everyday use, a few habits keep the coil healthy. Do not let the tank run close to empty, because a half-dry wick is the quickest route to burnt cotton. Take measured puffs rather than long chain draws that outrun the wick, particularly with thicker liquids. Open the airflow a little further at higher power, as extra airflow cools the coil and reduces stress on the cotton.

Lastly, handle the used coil responsibly when it is time to replace it. Spent coils contain residual nicotine liquid, so avoid skin contact, wash your hands afterwards and keep them away from children and pets. Do not put them in household recycling. Seal them in a bag and take them to a vape recycling point or a household waste recycling centre that accepts small electrical items, and ask your retailer whether they run a take-back scheme.

Troubleshooting Common Problems

Most coil problems have a short list of causes, and most of them are easy to fix once you know what to look for. Work through the symptoms below before concluding the coil is faulty.

• Burnt or acrid taste: usually a dry wick. Check the liquid level, allow longer for priming, lower the power and take shorter, gentler puffs. If the burnt taste does not clear after a couple of tank fills, the cotton has scorched and the coil needs replacing.
• Weak or muted flavour: the coil may be gunked up with sweetener residue. Try a fruit or menthol liquid to see if flavour returns. If you recently changed power or airflow, return to the middle of the printed range. A coil that is simply old will also taste flat.
• Gurgling or spitting: liquid is reaching the airflow path. Check that the coil is fully seated and the O-rings are intact, reduce the fill level slightly and make sure you are not running a very thin liquid in a coil that wants a thicker one. Spitting can also come from over-priming, so wipe the tank rim and the device contacts dry.
• Leaking from the base: an unseated coil, a damaged seal, or a cracked tank is the usual cause. Strip the tank, dry everything, refit the coil carefully and avoid overfilling. Leaks that continue with a different coil point to the tank itself.
• Dry hits on a fresh coil: the cotton was not primed or the liquid is too thick for the power. Re-prime, wait longer after filling and consider a thinner liquid or a lower wattage.
• Device says check atomiser, no coil or short circuit: the connection is poor or the coil is spent. Clean the contact pin with a dry cotton bud, make sure the tank is screwed in properly and try a known good coil. If the error remains, check the battery and the device.
• Coil lasts only a few days: power set too high, sweet liquids, chain vaping or a low liquid level. Adjust one thing at a time and see which has the biggest effect.
• Hot vapour or a harsh draw: reduce wattage and open the airflow wider. Heat that builds as the session continues can be a sign the wick is starving.

If a coil fails very quickly under correct use, or arrives with a visible defect, keep the packaging and contact us with the details. Photographs of the coil and the markings on the pack make it much easier to resolve a fault.

Value for Money and Coil Lifespan

Judging value on a consumable means looking at cost per week of use, not just the price on the page. A coil that costs a little more but lasts twice as long is cheaper in practice, and one that tastes better over its life is worth more than one that fades after a few days.

As an illustration only, using round numbers that are not our price, imagine a pack of five coils costs £10 and each lasts about ten days. That works out at £2 per coil, or around 20p a day for the hardware. Add the cost of e-liquid and you have a full picture of your running cost. Check the pack size and current price on the listing and run your own numbers the same way.

Several habits stretch coil life and improve value:

• Run inside the printed wattage range, and towards the middle of it rather than the top.
• Prime properly every time you fit a new coil, and do not fire a dry head.
• Choose lower-sugar liquids where you can. Fruit, menthol and tobacco profiles leave less residue than dessert liquids.
• Keep the tank topped up, because a low liquid level starves the wick.
• Rinse the tank between coil changes so old residue does not shorten the new head's life.
• Avoid chain vaping, which gives the cotton no time to re-saturate between puffs.

Compared with disposables, the maths generally favours refillable setups for regular vapers. A disposable bundles the battery, the liquid and the coil into one device that is thrown away, and single-use disposables can no longer be sold in Great Britain. With a refillable tank you keep the battery device and the tank, and only the coil and the liquid are consumed. Over a month, the saving for someone who vapes daily is usually clear, though it depends on your liquid choice and how often you change coils.

There is an environmental angle too. A coil head is a small amount of metal, cotton and plastic, whereas a disposable device contains a lithium battery, a circuit board and a plastic shell that is far harder to recycle. Used coils still need responsible disposal through a vape or small electrical item drop-off point, but the overall waste per week is much lower.

If you are unsure about the number of coils to order, many regular vapers keep one or two spares so a failing coil never leaves them without a working device. Spares are small, light and keep well when stored sealed.

How It Compares With Other Coil Options

There is no single right coil for every vaper, and an honest comparison has to include the situations where another option is a better match.

Against round-wire coils. Older style coils such as Aspire's own bottom vertical coil heads use a wound wire rather than a mesh sheet. They are often cheaper per head and some people prefer their slightly warmer, softer flavour. Mesh generally gives faster ramp-up, more vapour at the same power and a more even temperature, but it is more sensitive to thick liquids and wicking problems. If you value forgiveness and low cost over vapour output, a round-wire coil can still make sense.

Against other brands' mesh coils. Well-known mesh families from Vaporesso, SMOK, Voopoo and Uwell are widely sold and often fit large installed bases of kits, so they are easy to find. Where those coils differ is mainly in the tank and device they are made for, because coils are not interchangeable across brands. The practical point is that you should choose the coil your tank was designed for. An Aspire tank takes Aspire heads, and switching brands means replacing the tank or device as well.

Against pod cartridges. Many pod systems use a coil built into a sealed cartridge. These are simpler to use and reduce leaks, but you replace the whole pod, which can cost more over time and gives you less control over power. A tank with replaceable coils costs less per replacement part and lets you adjust wattage, airflow and liquid, at the cost of more hands-on upkeep.

Against disposables. Disposables need no setup, but they are no longer legal to sell in Great Britain, are fixed at one flavour and one nicotine strength, and generate more electronic waste. A refillable setup is the reusable alternative.

Where does the AF mesh coil fit? It suits someone who already has the matching tank, wants dependable mesh performance across a clearly defined range of resistances, and is prepared to prime and maintain the head. It is not the cheapest option per piece, and it will not suit someone who wants zero maintenance. Treat it as a well-matched part for a specific tank, not a universal answer.

Before you buy, confirm three things: that the coil is listed as compatible with your tank, that the variant sits in the power range your device and battery can support, and that you have a liquid and a nicotine strength suited to that resistance band. Get those right and the coil should do exactly what it is designed to do.
