Open vs closed vape systems are the two main choices for anyone switching from cigarettes to vaping. But which one saves you more money in the long run? Which is easier for a beginner? And how do European regulations affect your decision? In this guide, we compare open vs closed vape devices across cost, convenience, flavour variety, and environmental impact – helping you choose the perfect system for your needs.

Both types are legal under the EU Tobacco Products Directive (TPD). Closed system pods are limited to 2ml, and nicotine strength is capped at 20mg/ml. Open systems must also comply, but many offer larger tanks (sold with 2ml reducers for TPD compliance). Let’s dive into the details of the open vs closed vape debate.

Open vs Closed Vape: What Are the Differences?

Closed system (pre‑filled pods): The device uses sealed cartridges that come pre‑filled with e‑liquid. When the liquid runs out, you dispose of the whole pod and click in a new one. You never touch e‑liquid.

Open system (refillable pods or tanks): You manually fill a refillable pod or tank with e‑liquid from a bottle. You can choose any flavour and nicotine strength (within TPD limits). When the pod or coil wears out, you replace only that small part – not the entire device.

Understanding this open vs closed vape distinction is the first step to making a cost‑effective choice.

Open vs Closed Vape: Upfront Cost Comparison

Average prices across Europe (Germany, France, Italy, Spain, Poland, UK):

• Closed system starter kit: €15–€30 (battery + 2‑3 pre‑filled pods).
• Open system starter kit: €25–€50 (refillable device + empty pod + a 10ml e‑liquid bottle).

Winner for upfront cost: Closed system. You can start with less money immediately.

Open vs Closed Vape: Long‑Term Running Cost

Here the difference is dramatic. Pre‑filled pods cost €3–€6 per pod (2ml). A moderate vaper (2ml/day) uses one pod per day: €90–€180 per month.

With an open system, a 10ml e‑liquid bottle costs €4–€8 and lasts 5 days (€24–€48 per month). Add a replacement coil every 1‑2 weeks (€2–€4 each): +€8–€16 monthly. Total open system monthly cost: €32–€64.

After three months, closed system costs €270–€540; open system costs €96–€192. Winner for long‑term cost: Open system – you save 60‑70% every month.

Convenience: Open vs Closed Vape Systems

Closed system: No leaks, no filling, no mess. Just click and vape. Ideal for absolute beginners or anyone who hates tinkering.

Open system: Requires filling, occasional spills, and coil changes. But modern refillable pods (like Kamry’s) are leak‑resistant and easy to top up – takes about 30 seconds.

Winner for convenience: Closed system, but the gap is shrinking.

Flavour Choice & Flexibility in Open vs Closed Vape

Closed system: Limited to the flavours the brand offers (often tobacco, menthol, fruit). In some European countries (Netherlands, Denmark) non‑tobacco flavours are already banned for closed pods, further restricting choice.

Open system: You can use any e‑liquid from any brand – thousands of flavours. Even if a flavour ban comes, you can buy aromas and mix yourself (DIY). You can also adjust nicotine strength freely.

Winner for flavour: Open system, overwhelmingly.

Device Lifespan & Waste

Closed system: Each pod is single‑use plastic+metal+coil – a lot of waste. Several European countries (France, Belgium) are considering extra taxes on non‑refillable pods.

Open system: One refillable pod lasts weeks or months. Only the small coil is replaced. Much less waste.

Winner for environment and lifespan: Open system.

Open vs Closed Vape: Which Is Right for You?

Choose closed system if:

• You want the simplest “click and vape” experience
• You don’t mind paying 2‑3x more per month
• You only like basic tobacco or menthol flavours
• You vape occasionally (e.g. social use)

Choose open system if:

• You plan to vape daily (to quit smoking completely)
• You want to save money after the first month
• You enjoy trying different flavours or want to be future‑proof against flavour bans
• You care about reducing plastic waste

Most experienced vapers eventually switch from closed to open. Many start with a closed system for a few weeks, then move to a refillable device like those from Kamry, which offer excellent build quality and leak protection at a fair price.

Frequently Asked Questions (FAQ) – Open vs Closed Vape

In the open vs closed vape debate, can I use any e-liquid in a closed pod?

No. Closed pods come pre‑filled. You cannot refill them with your own e‑liquid (unless you hack them, which is not recommended). If you want flexibility, choose an open system.

Is an open vape system allowed under TPD?

Yes. Open systems are fully legal across the EU and UK as long as they comply with tank capacity limits (2ml for pods/clearomisers sold in most EU countries). Many open systems come with a 2ml reducer or are sold as TPD version.

Which open vs closed vape system is better for quitting smoking?

Both work, but open systems may be slightly more effective because you can gradually reduce nicotine strength by choosing different e‑liquids. Closed systems usually come in fixed strengths, making step‑down harder.
