How Long Does Helium Last?
A common question before any event: how long does helium last in balloons? It depends on the balloon type.
Benefits & features
Plan your float time
Latex floats for hours and foil for days — inflate close to the event, and we will help you pick the right helium.
Disposable & refillable choice
Grab a single-use canister for a one-off party, or step up to a refillable cylinder for weddings, events and trade balloon work.
Collection & local delivery
Collect from our Kent base and stockist network, or order helium online for local delivery — inflate where the party is.
How long different balloons hold helium
- Latex balloons — typically float for around 12 to 24 hours. A Hi-Float coating inside the balloon seals the latex and can extend this considerably.
- Foil balloons — hold helium far longer, often several days to a couple of weeks, because the foil leaks gas much more slowly than latex.
Temperature matters too: heat expands the gas and speeds up leakage, so balloons fade faster in a hot room or direct sun.
Tips for longer float time
A few simple habits keep balloons up longer:
Inflate close to the event rather than days ahead, treat latex with Hi-Float for a longer float, choose foil where you need balloons to last, and keep them out of heat and direct sunlight. Avoid over-inflating — a slightly under-filled balloon copes better with a warm room.
Frequently asked questions
How long does helium last in a latex balloon?
Usually around 12 to 24 hours. A Hi-Float coating inside the balloon can extend the float time considerably.
How long do foil balloons stay up?
Foil balloons hold helium far longer than latex — often several days to a couple of weeks, as the foil leaks gas much more slowly.
How do I make helium balloons last longer?
Inflate just before the event, use foil balloons or treat latex with Hi-Float, and keep balloons out of heat and direct sunlight.
