Last Updated on February 23, 2024 by Kimberlee Johnson

Balloons add liveliness to any party or celebration, bringing bursts of color, happiness, and delight to the atmosphere.

But as much as we love these floating orbs of happiness, their lifespan is often a mystery. 

We find ourselves wondering: how long will latex balloons stay inflated? Will they last through the entire party, or will they start to droop and sag halfway through? 

So, today, we’ll explore the factors that influence how long latex balloons will stay inflated and provide tips for ensuring that your balloons last as long as possible. 

Read on to learn more.

How Long Do Latex Balloons Remain Inflated?

Latex balloons typically remain inflated for 18-24 hours, although the exact amount of time varies depending on the size of the balloon and the conditions in which it is stored. 

It tends to last longer when stored in a cool, dry environment. If you want to make the balloons last longer, you can fill them with helium, lasting around 24 hours. 

Of course, if you like to keep balloons last longer, you can always use mylar balloons instead.

But how long do air-filled latex balloons remain inflated?

How To Keep It Inflated Longer?

The lifespan of a latex balloon can be extended with a few simple steps. The first step is to fill the balloon with helium as soon as possible. 

Helium is a much lighter gas than air and will help keep the balloon afloat for longer. 

The second step is to use a tight knot when tying the balloon. It ensures that the balloon will not deflate too quickly. 

Besides, tying the balloon with a small ribbon can help the knot stay in place. Finally, keeping the balloons away from extreme temperatures will help maintain their shape.

How Long Will Latex Balloons Survive Without Helium?

In general, latex balloons can last between eight and ten hours without helium, depending on the conditions and the quality of the balloons. 

But if you want the balloons to last longer, helium is the best option. Depending on the temperature and humidity, helium-filled balloons can last up to a week or longer. 

As a matter of fact, helium balloons will float and create a festive atmosphere, which is why they are often chosen for special occasions.

But what are ways to get your balloons to float without helium?

How Long Will An Air-Filled Latex Balloon Remain Inflated?

An air-filled latex balloon can remain inflated for 6-8 weeks, depending on the temperature and humidity of the environment. 

“Nobody can be uncheered with a balloon.”

A. A. Milne, Writer

In average room temperature and humidity, a latex balloon should stay inflated for at least 24 hours, sometimes up to a week or more.

What Causes Latex Balloons To Lose Air?

The main reason why latex balloons lose air is due to a process called oxidation. 

Oxygen molecules in the air react with the molecules in the latex, causing the balloon to become porous and eventually leak air. 

This process begins immediately after the balloon is filled with air, so even if you don’t use it immediately, it will lose air over time. 

Heat and sunlight can also speed up the oxidation process, so storing latex balloons in cool, dark places is best.

But why do balloons lose their shape when it’s cold?

How Long Will Latex Balloons Survive Without Hi-Float?

Latex balloons will survive without Hi-Float for roughly 8-10 hours, similarly when it is not filled with helium.

So, it is recommended to use in extending the life of latex balloons. 

This sealant helps the helium stay in the balloon for an extended period and can extend the life of balloons for up to two months. 

If you don’t use Hi-Float, the balloon will lose air pressure and pop over time. But how much do balloons cost at Disney World?

What Temperature Causes Latex Balloons To Lose Their Air?

Latex balloons begin to lose their air when temperatures reach 45-50°F or higher. This temperature causes the latex to expand and contract, which results in the air inside the balloon escaping. 

At temperatures above 60°F, the air will escape the balloon much quicker. It is best to keep latex balloons in a cool and dry environment to prevent this.


How long does a balloon take to deflate naturally?

It depends on the size of the balloon and the air pressure inside it, but generally, a balloon will deflate naturally in a few minutes once it is filled with helium or air. 

But how can you prevent helium balloons from deflating?

Does the cold cause air-filled latex balloons to deflate?

Yes, cold air can cause air-filled latex balloons to deflate. 

The balloon will eventually deflate because cold air is denser than warm air, and the latex material is not strong enough to sustain the pressure.

Is it possible to deflate and reuse a latex balloon?

Latex balloons are naturally occurring elastic material that stretches when inflated. It will quickly biodegrade and oxidize if exposed to a hot or cold temperature [1]. 

Is there a balloon that doesn’t deflate?

Technically, there is not a balloon that does not deflate, as all balloons will eventually lose their air and become flat unless you re-inflate it. 

On the other hand, helium cylinders are a new type of balloon that, according to some, will not lose air pressure in extreme heat or cold [2].

Let’s Sum It Up

Latex balloons can stay inflated for a considerable amount of time. 

And while they may not last as long as other balloons, their biodegradable nature, and cost-effectiveness make them an excellent choice for any party. 

With proper care and maintenance, you can ensure that your latex balloons stay inflated for several hours, creating a fun and festive atmosphere for your guests to enjoy.
