You have probably noticed many times that the ordinary balloons that you inflate yourself with your own breath only don’t last so long and usually, they are already wrinkled after less than a week.

It’s mostly because we can’t properly inflate them whilst when being inflated correctly, they can last for a very long period of time, approximately for weeks or even longer

Another odd trait of the balloons filled with the air is that they won’t float if you put them in a room.

That is why helium-filled balloons have become so widely popular nowadays! How long does helium in balloons last? The balloons inflated with helium last less than air-inflated ones but they can charmingly float in your room making it look cheerful and nice.

How long does helium last in balloons? Usually, when being inflated with helium, an eleven-inch balloon can last approximately from ten to twenty hours.

If someone blows it up accidentally, its duration won’t be that long.

So what affects the lifespan of the helium-filled balloons?

  • First of all, a helium balloon lifespan depends on how tightly and properly the end of the balloon is fixed and how safe the balloon is itself.
  • Also, the temperature in the room where the balloons are kept matters a lot. The balloons inflated with helium are best to be kept at the even and comfortable room temperature, not too hot and not too cool.

That’s why it’s also advised not to transport your balloons in a car when they are already inflated. Moreover, keeping them close to the heaters or the air conditioner can also cause them to deflate soon.

  • Another issue that you might not be aware of is that the balloons must be taken out of the balloon transport bag ASAP because when staying inside for too long, their durability becomes lower.
  • The material which was used for the balloons is also essential. For example, latex balloons release helium faster because this material is porous whilst foil balloons can remain afloat much longer.
  • And finally, the bigger the balloon the longer it will last! The average 11 inches balloon made of latex normally remains afloat for a maximum of twelve hours. Instead, the same latex balloon of 90 cm will last for three to five days!

Pay attention to all of these factors when choosing what balloons to buy!

Foil balloons filled with helium usually last for five or even seven days if they are being kept under the proper conditions and were blown up correctly.
