If you’ve ever noticed that balloons from the supermarket seem to droop by the end of the day, while balloons from professionals stay floating beautifully much longer, there’s a reason. The lifespan of a helium-filled balloon depends on several key factors: balloon quality, size, helium purity, treatment, humidity, environment, and, of course, care and handling. At Salem Balloons and Flowers, we take all of these seriously to ensure your balloons last as long as possible.

Balloon Quality Matters

Most supermarket balloons are made from standard latex, which is more porous. This allows helium to escape quickly, which is why they often float for 6–8 hours.

We use professional-grade latex balloons, which are:

• Thicker

• Less porous

• Manufactured to hold helium longer

Even without treatment, professional latex balloons typically float 12–14 hours, but we go further... we treat our balloons to extend their floating time,

Balloon Treatment Makes a Difference

Latex is naturally breathable, so helium slowly escapes unless the inside of the balloon is treated. To extend float time, we apply a professional balloon sealant that coats the inner surface, slowing helium loss.

Because of this, our latex balloons are guaranteed to float for at least 24 hours, and often much longer when kept in ideal indoor conditions.

We also inflate balloons as close as possible to event time, even if that means starting at 4 AM. Quality and performance matter to us.

The Type of Helium Used Matters Too

Not all helium is pure helium.

• Small, store-bought tanks (the pink type found in party aisles) are commonly filled with an 80/20 helium–air blend, which significantly shortens float time.

• We only use 100% pure helium from a certified industrial supplier.

This ensures maximum lift and longer-lasting float times.

How long can larger balloons float?

Larger balloons naturally hold more helium, so they float longer than standard 11" balloons. In ideal indoor conditions, treated high-quality latex balloons commonly float:

The actual float time varies based on:

• Temperature and sunlight exposure

• Humidity

• Helium purity

• How tightly the balloon is inflated (over-inflating thins the latex)

• Whether the balloons are outdoors

• How much your balloons are handled during transport or at their final destination.

• Proximity to heaters, fireplaces, A/C, or fans

These factors affect how quickly helium escapes from the balloon.

Environment Matters

To get the most out of your balloons:

• Keep them indoors whenever possible.

• Avoid direct sunlight.

• Keep away from heaters, fireplaces, blowers, and vents.

• Store and display them in a cool, stable environment.

Heat expands helium (which can cause popping), and cold compresses helium (which can make balloons sag temporarily).

In Short

The lifespan of helium balloons depends on:

• Balloon Quality

• Treatment

• Helium Purity

• Balloon Size

• Temperature & Handling

At Salem Balloons and Flowers, we maximize every factor we can to provide balloons that stay stunning and joyful for as long as possible.

We can’t control the weather, but we can ensure your balloons start at their highest quality and longest float potential.
