When you purchase a dispenser every single one of them is refillable, the only thing is you must know how it has to be done. Generally, to replace the refill of the dispenser you would have to look for and press a release button. This could be red or green or even a normal button like any other. Once that is done you will be able to open the device to change your refill. From there you can gently pull out the empty refill and replace it with a new one. In other cases, you would have to pour in your sanitizer into the refill and then close it. You know the gadget is shut back again properly when you hear a click sound into the machine. To fill and reuse the refill of the dispenser is always an easy, cheaper and environment-friendly option than to go purchasing a new refill all together each time.
