Eleaf GS Air Series and EC Head Coils: What Is in the Pack

Eleaf GS Air Series and EC Head coils are replacement heating heads for refillable vape tanks made by Eleaf. They are sold as a consumable accessory, so the pack contains five coil heads and nothing else: no tank, no battery, no e-liquid and no charger. Each coil head is the small cylindrical part that sits inside the tank base, soaks up e-liquid through a cotton wick and turns it into vapour when you press the button or draw on your device. Over time the cotton darkens, flavour flattens and vapour thins out, and at that point the coil needs replacing. A pack of five means you have several changes in hand rather than a single spare, which suits anyone who vapes daily.

This listing covers a family of three variants. They differ in the coil head type and resistance, and the variant you choose has to match the tank you own. The GS Air side of the range was designed around Eleaf's GS Air style tanks and has historically been associated with higher-resistance heads that suit lower wattage and a tighter, more cigarette-like draw. The EC side of the range was designed for the Eleaf Melo and iJust style tanks and tends to cover lower-resistance, sub-ohm style heads that handle more power and produce larger clouds. Because the names are similar but the parts are not interchangeable, matching the head to your tank is the single most important step before ordering.

• Pack size: 5 replacement coil heads per pack.
• Product type: consumable replacement coil, not a complete vape.
• Brand: Eleaf, a long-established name in refillable tanks and mod-style kits.
• Nicotine: none supplied; coils contain no e-liquid until you prime and fill them yourself.
• Intended users: adult smokers and existing vapers who already own a compatible Eleaf tank.

This page walks through compatibility, how the coils are built, what to expect from vapour and flavour, which nicotine strengths pair sensibly with each type, how to fit and prime a head, what goes wrong and why, and how the value stacks up against other coil options. It is written for UK vapers, so the regulations that shape what you can legally buy and fill are covered where they matter. You must be 18 or over to buy this product.

Compatibility: Matching the Coil Head to Your Tank

Coil heads are not universal. Each tank is engineered around a particular thread, seating depth, airflow path and wick-hole arrangement, and a head that is even slightly wrong either will not seat, will leak, or will deliver a poor draw. Before you buy, look at your tank's base or the packaging it came in and find the name of the coil it uses. Eleaf prints the coil name on the base of most heads, usually alongside the resistance, for example a code beginning GS Air or EC followed by a letter or number. If the code on your spent coil matches the variant you are ordering, you are safe.

As a general guide, the GS Air heads in this family belong to the GS Air tank line and a handful of Eleaf starter-style devices built around the same coil interface. The EC heads belong to the wider Melo and iJust style tank lines, which Eleaf has released in several sizes and editions over the years. Within the EC family there are multiple sub-types, and a head from one sub-type will often not suit a tank that was built for another. Treat the family name as a starting point and the printed code on your old coil as the final check.

• Step one: unscrew the base of your tank and pull out the old coil head.
• Step two: read the code and resistance stamped on the coil's metal collar or side.
• Step three: pick the variant on this page with the same code.
• Step four: if the code is not clear, check the manual or the tank's product page before ordering.

Pay attention to the tank edition as well. The UK market is served by tanks with a capacity capped at 2ml, while some international editions are larger. The coil usually fits both, but if you are importing a tank or using a non-UK edition, double-check that it uses the same coil family. Also be aware that some tanks ship with two different coils in the box, one lower and one higher resistance. The one fitted at the factory is not always the one you will want long term, so having both types in a pack can be useful while you work out your preferred setup.

If you are unsure which variant fits your device, it is better to ask before ordering than to guess. Returns on opened coil heads are limited for hygiene reasons, so a wrong guess can cost you the pack.

Coil Construction and Heating Technology

Every coil head in this family follows the same basic design. A length of resistance wire is wound into a coil and threaded through an absorbent cotton wick. The ends of the wick sit in small channels around the head, and those channels draw e-liquid in from the tank by capillary action. When the device applies power, the wire heats up, the saturated cotton delivers a thin film of liquid to the wire surface, and that liquid vaporises. Everything is housed in a metal shell with a threaded base, and a silicone seal keeps the e-liquid from leaking through the bottom. The head is a sealed, throwaway unit, so there is nothing to rebuild or clean beyond a quick prime.

The difference between the GS Air and EC sides of the range comes down to wire length, number of wraps, wick density and the size of the intake holes. A higher-resistance head uses a thinner or longer wire path and has smaller intake holes. It heats gently, uses less power and pairs naturally with tighter airflow, so vapour comes through slowly and the draw feels more like a cigarette. A lower-resistance head uses a shorter or thicker wire path with larger intake holes and a thicker wick. It tolerates more power, moves more liquid and produces warmer, denser vapour with an open airy pull.

• Wick material: organic-style cotton is typical for heads in this family, chosen for clean flavour and quick saturation.
• Wire type: resistance wire such as kanthal-type or stainless steel is common; the exact alloy and wattage range are printed on the head or packaging.
• Resistance: expressed in ohms; lower values draw more current and are rated for higher wattage.
• Intake holes: sized to the tank's expected e-liquid viscosity, which matters when you choose between high-VG and high-PG juices.

The practical consequence is that the head and the e-liquid have to be matched. A thick, high-VG liquid can starve a head with small intake holes because it cannot flow through quickly enough, which leads to dry hits. A thin, high-PG liquid can flood a large-hole head and cause leaking or gurgling. The variants in this family are designed with a particular liquid thickness in mind, which is why the nicotine and VG guidance later in this page is tied to the head type rather than given as a single universal figure.

Performance and Vapour Delivery

Performance with a replacement coil is mostly about consistency. A fresh Eleaf head should fire immediately after priming, deliver smooth vapour for the first few days, and hold that quality until the cotton begins to degrade. Higher-resistance GS Air style heads deliver modest vapour volume and a cooler, tighter pull. They are what most people mean when they describe a mouth-to-lung draw: you draw into your mouth first, pause, and then inhale. Because they use less power, they tend to run for longer on a charge and use e-liquid slowly, which also makes them economical.

Lower-resistance EC style heads deliver considerably more vapour. They are designed for a more open pull, where you inhale straight into the lungs without a pause. At the higher wattages these heads are rated for, the vapour is warmer and the clouds are larger, but e-liquid consumption rises sharply. Expect to refill the tank noticeably more often than with a high-resistance head. If you are moving from a GS Air style head to an EC head, expect the same 2ml tank to empty far faster than you are used to.

• Ramp-up: a freshly primed head should reach full vapour production within a second or two.
• Consistency: output stays steady through the first stretch of life, then gradually drops as the cotton ages.
• Throat feel: tighter heads give more throat hit at a given nicotine strength; open heads feel smoother at the same strength.
• Power sensitivity: running a head above its rated wattage burns the wick quickly and shortens its life.

For anyone concerned about puff counts, note that a coil head does not have a puff count of its own the way a disposable does. The number of draws you get from a head depends on how hard you vape, the power you use, the e-liquid, and how well you keep the tank topped up. As a rough guide, a light user may get a couple of weeks from a head, and a heavy user on a lower-resistance setting may need to change it within a week. That is covered properly in the value section below.

If performance drops suddenly rather than gradually, the cause is almost always a dry or flooded head rather than a faulty product. The troubleshooting section sets out what to check before you assume a coil is defective.

Flavour Profile and Suitable E-Liquids

A new coil head is the biggest single influence on flavour in a refillable setup after the e-liquid itself. The cotton wick is neutral when fresh, and the small mass of the head means it heats quickly and evenly, so the liquid you put in is the flavour you taste. Fruit, menthol, dessert and tobacco profiles all come through cleanly in the early life of a coil. As the head ages, residues from sweeteners and flavour compounds build up on the wire and wick, and flavours first dull and then take on a slightly burnt or muddy edge. That is the signal to replace the coil, not to push the power up.

Higher-resistance heads concentrate flavour well because the lower power keeps vapour temperature moderate. Delicate fruit and menthol blends do especially well here, as do tobacco and bakery-style profiles. Lower-resistance heads produce a warmer, fuller vapour that suits sweeter, creamier and layered flavours, although at high power the extra heat can flatten delicate notes.

• Suits GS Air style heads: nicotine salts, 50/50 or 60/40 PG/VG blends, fruit ices, menthol, tobacco, and thin e-liquids generally.
• Suits EC style heads: higher-VG liquids such as 70/30 or 80/20 VG/PG, shortfills and low-nicotine freebase liquids, dessert, custard and sweet fruit blends.
• Be cautious with: very sweet, heavily sweetened liquids, which gunk up any coil faster and shorten its lifespan.
• Avoid: flavour concentrates or any liquid not made for vaping; only use e-liquid sold for use in vape devices.

If you change flavours often, remember that cotton retains a trace of what came before. Switching from a strong menthol to a delicate fruit in the same head will taste muddled for a few draws. Some vapers dedicate a coil to a single flavour family for that reason, and a five-pack makes this practical. You could set aside one head for menthol, one for fruit and one for dessert flavours, and swap between them when you change liquid. It is a small step that keeps each profile tasting clean.

Always let the head fully absorb the e-liquid before firing, and avoid running the tank near empty. A starved wick is the quickest route to a burnt taste, and a burnt head cannot be recovered; the flavour will stay harsh even after you refill.

Design and Build Quality

The coil heads in this family are small, compact assemblies, and the build is straightforward and consistent. The outer shell is metal, the base carries a threaded or push-fit collar depending on the tank, and a silicone O-ring provides the seal. Eleaf prints the coil designation and resistance on the head so you can identify it after it has been removed, and the heads are sold in a sealed pack of five so each one arrives clean and unhandled. On opening, check that the silicone seal is present and unmarked and that the cotton is intact in the intake holes, which is simple to do by eye.

Manufacturing tolerances on replacement coils matter more than people tend to think. A head that sits slightly proud of its seat can cause an air leak, and one that seats too deep can restrict airflow. Genuine Eleaf heads are made to the dimensions of Eleaf tanks, so the fit is snug and the seal is reliable. That is one of the main arguments for buying genuine heads rather than unbranded copies, which vary in wick quality and fit.

• Shell: metal with a plated finish, resistant to normal handling.
• Seal: silicone O-ring to prevent leaks from the base.
• Wick: cotton, held by the head's internal structure so it cannot slip out in use.
• Marking: coil code and resistance printed or stamped for easy identification.

Handling is also worth mentioning. Keep the head by its metal body when fitting, and avoid touching the open wick holes with your fingers, which can transfer oils and make priming harder. Store unused heads in their pack, somewhere dry and away from direct heat, until you need them. Avoid leaving a pack in a hot car or a window sill where the silicone and wick can degrade.

On environmental handling, used coil heads contain metal and cotton and are small electrical components in the broad sense. In the UK, spent vape parts should not go in household recycling or general waste. Take used coils to a vape recycling drop-off point, which many UK vape shops and some retailers provide, or to your local household waste recycling centre where it accepts small electricals. Pour out any leftover e-liquid first and keep the coils away from children and pets.

Power, Batteries and Charging Considerations

Because a coil head is a consumable part, it has no battery of its own and no puff-count rating the way a disposable does. What matters is how it interacts with the battery in the device you pair it with. Eleaf devices that use these heads range from compact pen-style kits with built-in batteries in the low thousands of milliamp-hours at most, to larger mod-style devices with higher capacity or removable cells. In every case the rule is the same: the coil determines how much power the device sends, and the power determines how fast the battery drains.

A higher-resistance head draws less current, so a given battery lasts longer between charges. A lower-resistance head draws more current and demands more of the battery, so you can expect to charge more often. For a built-in battery device, that might mean charging every day or two with a lower-resistance head, compared with every few days using a higher-resistance one. These are general patterns and not guarantees, because the exact runtime depends on your device's capacity, your puffing habits and the wattage you set.

• Stay inside the rated wattage: the range is printed on the coil or packaging; going above it shortens life and risks a burnt taste.
• Charge safely: use the cable supplied with your device or a reputable USB cable and a standard USB wall adapter, and do not leave a device charging unattended overnight.
• Check the battery level: low batteries can lead to weaker vapour that is easily mistaken for a failing coil.
• Keep contacts clean: dirty connections between the tank and battery can cause a firing error that looks like a coil fault.

If you are using a regulated device with adjustable wattage, begin at the low end of the coil's range and move up slowly until the vapour and flavour are where you want them. Starting low is safer for a fresh coil and gives the wick time to saturate. Raising the power one or two watts at a time is better than jumping straight to the maximum. If you use a device with an automatic coil recognition feature, it will usually read the resistance on installation and suggest a wattage, which is a sensible starting point.

Never use a damaged battery or charging cable, and dispose of old batteries through proper battery recycling points, not household bins.

Nicotine Strength Guidance

Coil heads contain no nicotine; the strength comes from the e-liquid you fill the tank with. That said, the coil you choose should shape the strength you pick. UK law caps nicotine in e-liquids and disposable vapes at 20mg/ml, and refillable e-liquid is sold in bottles of no more than 10ml, with tank capacity limited to 2ml. Within those limits, the right strength depends on how you vape, and the head type has a large bearing on that.

With a higher-resistance GS Air style head, the tight draw and low power produce a strong throat hit and a small volume of vapour per puff. Many people using this setup find nicotine salt e-liquids in the 10mg to 20mg range the most comfortable, because salts feel smoother at higher strengths. If you prefer traditional freebase liquids, 6mg to 12mg is a common range for this kind of draw. A former heavy smoker may start near the top of that range, while a lighter smoker can step down.

With a lower-resistance EC style head, you inhale much more vapour per puff at higher power, which delivers far more nicotine than the same strength through a tight head. Strengths in the 3mg to 6mg freebase range are typical for open-draw vaping, and many vapers go lower still. Using a high-strength nicotine salt through a powerful sub-ohm style head is likely to feel harsh and may deliver more nicotine than intended.

• Tight draw, low power: 10mg to 20mg nicotine salt, or 6mg to 12mg freebase.
• Open draw, higher power: 3mg to 6mg freebase, or lower strength shortfill blends.
• Moving between coil types: reduce strength when going from tight to open draw, and raise it when going the other way.
• Signs the strength is wrong: dizziness, headache, nausea or a harsh throat usually mean too high; constant cravings usually mean too low.

This guidance is general and not medical advice. Nicotine is addictive. These products are intended for adult smokers who want an alternative to cigarettes and are not recommended for anyone who has never smoked. If you are using vaping to quit, the NHS offers free stop smoking support, and your local service can help you plan a gradual step-down in strength.

Who These Coils Are For, and Who Should Skip Them

These coils make sense for a specific group of people. The most obvious is anyone who already owns a compatible Eleaf tank or kit and needs replacement heads. If your vapour has gone flat, your coil has gone dark, or you notice a burnt taste even with fresh liquid, a new head is the correct fix. Buying a pack of five suits people who vape every day, because the gap between changes is short enough that you will use all five over a few months.

They also suit people who want to experiment with coil types. Because this listing covers three variants, you can test a tight-draw head and an open-draw head across separate packs and compare how each suits your liquids. For someone moving away from cigarettes, a higher-resistance head with a tight draw often feels more familiar, while those used to larger clouds tend to prefer the open pull of a lower-resistance head.

• A good fit if you: own a matching Eleaf tank, vape daily, prefer genuine parts, and want a stock of spare heads.
• A good fit if you: are a smoker switching to vaping and already have a refillable Eleaf device.
• Not a fit if you: want a ready-to-use vape; this is a replacement part only and does nothing without a compatible tank and battery.
• Not a fit if you: have never smoked or vaped; nicotine products are for existing adult smokers only.
• Not a fit if you: are under 18; sale of vaping products to under-18s is illegal in the UK.

If you do not yet own a tank, buy that first. A coil on its own cannot be used, and the right coil depends on the tank. If you prefer a no-maintenance approach, a pod system with a pre-filled or refillable cartridge may be more convenient, and since the UK ban on single-use disposable vapes came into force, refillable and rechargeable devices are the main route for adult vapers. Using replaceable coils is also more sustainable than throwing away an entire device when the heating element wears out.

Finally, if you are a very light vaper who uses a device only occasionally, you may find a pack of five more than you need. In that case, a smaller pack of three or a single head may be a better match, although the per-coil price usually favours the larger pack for regular users.

How to Fit, Prime and Break In a New Coil

Fitting a replacement coil takes only a couple of minutes, but the priming step decides how long the coil lasts. A head fired dry will burn the cotton in seconds, and there is no way to undo that. Follow the sequence below every time, whichever variant you are using.

• 1. Empty and remove: turn the device off, unscrew the tank and pour out any remaining e-liquid. Unscrew the old coil head from the base and discard it appropriately.
• 2. Check the new head: look at the seal and wick, and confirm the code matches your tank.
• 3. Prime the cotton: put a few drops of e-liquid directly onto the exposed cotton through the intake holes until it looks fully saturated. Also put a few drops down the centre of the head.
• 4. Fit it in the tank: screw the head firmly into place without over-tightening. Over-tightening can damage the seal.
• 5. Fill the tank: fill with e-liquid up to the max line, taking care not to flood the central airflow tube.
• 6. Wait: leave the tank to stand for five to ten minutes so the wick can finish absorbing liquid. This is the step people skip most often.
• 7. Start low: set the lowest wattage in the coil's range, take a few short draws without firing, and then begin firing in short puffs.

For the first few puffs, vape gently and take shorter draws than usual. Leave a gap of fifteen to thirty seconds between puffs while the head beds in, and increase the power step by step. Many people notice a slight tang or papery taste during the first tank, which clears as the cotton settles. If you notice a burnt flavour straight away, stop immediately, because it usually means the wick was not saturated, and further firing will make it worse.

In daily use, keep the tank at least a third full. Letting it run low is the main reason heads fail early. Do not chain vape, meaning take puffs in rapid succession, because the wick cannot refill as quickly as it is being used. Wipe the tank threads and the battery connection occasionally with a dry cloth, and store the device upright to reduce the chance of leaks.

Troubleshooting Common Problems

Most coil problems have a simple cause, and most can be solved without returning anything. Use the checklist below before deciding a head is faulty.

• Burnt or acrid taste: the wick has dried out, the power is too high, or the coil is at the end of its life. Check the e-liquid level and lower the wattage. If the taste persists after a refill and a rest, replace the head.
• Weak vapour or muted flavour: the coil may be gunked up by sweet liquids or the battery may be low. Try a fresh charge first, then consider changing the head.
• Gurgling or spitting: the head is flooded or condensation has collected in the airflow path. Blow gently through the mouthpiece with the device off, and wipe away any liquid. Avoid overfilling.
• Leaking from the base: check that the head is seated properly and the silicone seal is intact. Make sure the tank is not overfilled and the liquid is not too thin for the head.
• Dry hits on a new head: usually caused by insufficient priming or a thick liquid. Re-prime, wait longer, and consider a thinner e-liquid or a head with larger intake holes.
• Device shows an atomizer or short circuit error: unscrew the tank, wipe the contacts, and refit. If the error remains, try a second head from the pack to rule out a single faulty unit.
• Hard to inhale: airflow may be restricted. Check that the airflow ring is open and nothing is blocking the intake.

A frequent misunderstanding is that a coil which tastes bad must be defective. In reality, a head that tastes burnt after a few days of heavy use has typically come to the end of its useful life. Likewise, a head that tastes burnt on the first tank is far more often a priming problem than a manufacturing fault. Rule out these causes before returning anything.

If you have worked through the list and a head still fails to fire, or you receive a pack with a visibly damaged coil, contact the shop with your order number and a photo. Faulty goods are covered by your statutory rights under the Consumer Rights Act 2015, and a damaged or defective item can be dealt with under that framework. Keep the original packaging and the faulty head until the issue is resolved.

Value for Money, Coil Lifespan and How These Compare With Alternatives

The cost of a pack of five coil heads should be measured per head and then per week of use, not as a headline price. A light vaper may get two weeks or more from a head, so a five-pack lasts two to three months. A heavy vaper using a lower-resistance head at higher power may change a head weekly, in which case the pack lasts about five weeks. Even in that heavy-use case, a branded pack of five tends to cost less per head than buying single replacements, which is the main reason to prefer multipacks.

What shortens coil life is almost entirely under your control. Sweet liquids, chain vaping, running low on e-liquid and high wattage all reduce lifespan, while priming properly, keeping the tank topped up and staying in the rated power range extend it. Small habits compound: a head that would last ten days with careless use can often last three weeks with care.

• Typical lifespan: roughly one to three weeks per head depending on use, liquid and power.
• Cost control: use less sweet liquids and stay within the rated wattage to stretch each head.
• Waste: replacing a coil is much less wasteful than discarding a whole device, and spent heads can go to a recycling drop-off.

On comparisons, it is fair to look at the main alternatives. Genuine Eleaf heads cost more than unbranded compatible heads, but the compatible versions vary widely in wick quality, fit and consistency, and a poor fit can leak or fail early. Against coils from other makers such as Aspire, Vaporesso or SMOK, Eleaf heads are not necessarily better or worse; the right comparison is whether the coil suits your tank. Those other brands make heads for their own tanks and are not interchangeable with Eleaf hardware. Mesh coils from other makers can offer broader, more even heating and a longer flavour life, but they are matched to different tanks. If you are open to switching ecosystems, it is worth comparing mesh options, while if you already own an Eleaf tank, staying with genuine Eleaf heads is the simplest and most reliable route.

Overall, the value case rests on three things: a pack of five reduces the per-head cost, genuine parts reduce the risk of leaks and poor fit, and a replaceable coil keeps your existing tank working for much longer than a sealed unit would.
