1. Lift tank out of box by handles.
  2. Eye protection should be worn for all following steps.
  3. Position the tank with the nozzle facing away from you. If the nozzle is loose, tighten it on its stem. Turn the valve handle counterclockwise three full turns.
  4. Hold the balloon with both hands. Stretch the balloon opening enough to slide it onto the nozzle.

  1. With one hand on the balloon neck and nozzle, pinch the balloon and press down on the nozzle. That hissing sound is the helium being released from the tank to fill the balloon. When your balloon reaches the recommended size, let up on the nozzle to stop the release of helium. But do not let go of the balloon.
  2. Remove the balloon by pinching it at the tip of the nozzle and sliding it off the neck off the nozzle shaft. Tie a knot in the balloon neck to secure helium from escaping.
  3. Please do not allow your helium-filled balloons to get out of your reach. Attach ribbon or string where you knotted the balloon, and tie them to something stationary, or use balloon weights.

  1. When you’re finished, close the valve by turning the valve handle clockwise until it’s tight.
  2. Bend the nozzle to release any extra pressure.
  3. Store the tank in its original box. If there is no more helium in the tank, please refer to our recycling and disposal instructions.

Inflating tips

Inflate balloons 1-2 hours before your party starts for best results.

The number of balloons you can inflate depends on the size and shape of the balloon you chose to create.  Do not over-inflate balloons.


Float Time Chart**

Reference the below chart for how long each balloon type will continue to float when inflated with helium. On average, you can inflate more 9ʺ latex balloons with each tank than larger foil balloons. However, foil balloons will float longer.



Balloon type/size Average Float Time
9" Latex
6-8 hours
11" Latex
12 hours
18" Foil
1 week
34" Foil
4-5 days

**Balloon inflation figures are based on indoor estimates at room temperature. Altitude, temperature, atmospheric pressure and humidity will affect float time and balloon size.

Recycling + Disposal

Ensure the safe and proper disposal of your Helium Balloon Tank by following these instructions.

Consult your local municipality or waste removal service to determine if disposable helium tank recycling is available. Bring your empty helium tank to a well-ventilated area.


  1. To confirm that the tank is empty, fully open the valve by turning the handle to the left, then bend the tilt nozzle gently but fully to release any remaining helium. Make sure all helium is released. If you hear or feel helium being released, continue to hold until you do not feel any pressure or hear any sound from the nozzle.

  1. When the tank is empty, unscrew the tilt nozzle anti-clockwise to remove.

  1. On the balloon tank near the blowout valve write “EMPTY” in bold text with a permanent marker, so that it is clearly visible. Please take the empty tank to a household recycling center or civic amenity site, or if permissible, leave with curb side recycling.

  1. If the recycling center, or curb side collection requires the blowout valve to be open to confirm that the tank is empty, take the following steps. The use of eye protection is advisable for this process. Locate the blowout valve on the shoulder of the balloon tank. Using a slotted (flat head) screwdriver, position the head in the depression at the edge of the ring, then, taking a mallet or hammer, tap the handle of the screwdriver lightly but firmly. Repeat in multiple places around the ring edge, until the metal ring covering the blowout valve is punctured.

  1. The punctured ring may be sharp. To avoid injury, use needle-nose or a similar type of pliers to pry the ring away from the helium tank, and place it in the trash.

  1. In addition to writing the word “EMPTY” in permanent marker, draw a circle around the punctured blowout valve.

NOTE: If recycling options are not available to you, please follow instructions 1 through 6 above, and place the disposable helium tank in your household trash.



Children under 8 years old can choke or suffocate on uninflated or broken balloons. Adult supervision is required when operating this helium tank. Keep uninflated balloons away from children, and discard any broken balloons immediately.
