Can you refill a Muha Meds disposable? No. The pen is a sealed, single-use unit, not built to be opened, topped up, or reused. Force it open and you break the seal, almost certainly damage the coil, and end up with a leaky pen that tastes burnt. It is the cheapest way to ruin a $20 pen. If you want something reusable, a 510 cart on a battery is the right tool.
Why a disposable is not designed to be refilled
A Muha Meds disposable is a 1g tank, a ceramic coil, a draw sensor, and a rechargeable battery bonded into one housing. There is no fill port and no removable mouthpiece. The factory seal keeps the distillate in place through shipping and temperature swings, and it is the same seal that keeps the pen from leaking in your pocket. Once you crack it, there is no putting it back.
The battery charges over USB-C only so it can outlast the oil it came with. Rechargeable does not mean refillable.
How to open a Muha Meds disposable (and why you should not)
People look up how to take apart a Muha Meds disposable either to refill it or to rescue oil from a pen that stopped firing. Here is what actually happens:
- The mouthpiece is press-fit. Prying it off usually cracks the plastic and pulls the coil housing loose with it.
- The tank cannot be re-sealed. Anything you pour in will leak past the coil and into the airflow channel.
- The ceramic coil is tuned for the original oil. Different oil tends to gurgle, spit, or taste burnt within a few pulls.
- The battery is inside the housing. Forcing a metal tool in there is a good way to short it.
If your pen still has oil but will not fire, charge it fully first: a blinking LED with no heat almost always means low charge. If it is clogged, warm it in your hands and clear the mouthpiece with a clean pin. Those two fixes rescue most “empty” pens without opening anything, and defective units are covered by our 14-day return window.
The reusable option: a 510 cart and battery
If you want hardware you keep, go with a cartridge. Muha Meds carts are 1g, 510-thread, ceramic-core cartridges that screw onto any standard 510 battery. When one runs out, unscrew it and screw on a fresh one; the battery lasts through many carts. Browse Muha Meds carts and pair one with a Muha Meds battery, about $16 at the time of writing. A Blue Slushie 1g cart plus a battery costs less than two disposables and gives you voltage control a disposable does not.
How to open a Muha Meds cart has the same answer: do not. Carts are sealed too, with the same leak and coil problems.
When a disposable still makes sense
Disposables are the simplest option: no button, no voltage menu, nothing to screw together. The current Muha Meds Gen 3 all-in-one has better battery life and a refined mouthpiece than earlier generations, and at around $20 for 1g it costs little more than a cart.

Frequently Asked Questions
How do I refill a Muha Meds disposable?
You do not. There is no fill port, and opening the housing breaks the seal and the coil. Buy a fresh pen or switch to a 510 cart.
How do you take apart a Muha Med cart?
Carts are sealed like disposables. Taking one apart leaks the oil and ruins the ceramic coil, so there is nothing to gain.
Is a cart and battery cheaper than disposables?
Over time, yes. Most carts run $12 to $20 and the battery is a one-time $16, while each disposable is around $20.
