How long do helium balloons last?

Float time depends on balloon size, material, and room temperature. As a quick rule: standard 11" latex float for hours (same day), larger latex last longer, and foil/mylar can last days. See our in-depth answer: How long do helium balloons last?

Is helium safe? Can kids use the tank?

Helium is non-toxic and non-flammable, but it displaces oxygen. Do not inhale.
Operate tanks in a well-ventilated area. Keep away from heat and open flame.
Adults only. Children may enjoy the balloons, but the cylinder and valve must be used by an adult.

How do I store and transport helium tanks?

Keep tanks upright, secured, and in a dry, ventilated place under 49°C/120°F.
It’s okay to transport by car if secured and handled gently. Crack a window slightly in case of leaks. Do not leave a tank in a hot vehicle.
Avoid damp areas and high-traffic walkways where the tank could tip.

What can I fill with a helium tank?

Helium tanks are made to inflate balloons designed for helium. Do not use on other items. For best lift and float:

11" latex balloons (classic colors)
Large foil letter balloons and 34" number balloons
Weights, ribbon & accessories

Troubleshooting & FAQs

My balloons don’t stay up as long as expected.
Check size and seal. Larger latex last longer; foil last the longest. Heat and cold reduce float time. See our float guide.

Can I refill latex or foil balloons later?
You can top up foil/mylar. Latex pores slowly leak helium; once tied, topping up may not help much.

Will heat/cars affect balloons?
Yes. Heat expands gas (pops/deflates later); cold shrinks gas (looks soft). Avoid hot cars and direct sun.

Can stores fill my balloons?
We offer fill and delivery in many cities. Check your city page for options.

Recycling, disposal & sustainability

Deflate balloons fully before disposal. Follow local recycling rules for foil/mylar.
Return rented tanks per your order instructions so we can safely re-use them.
