12" Jumbo Helium Balloon Tank Kit: Steel, Red, Birthday Party Accessory, Ages 18+, Balloon Time

A: Than you so much for the help

A: Yes it will, easily!

A: No, it's a one-time use tank.

A: no. packaging advises against refilling

A: No, it cannot be refilled.

A: We took ours to the county recycling center

A: I followed directions I found on YouTube which showed me how to use a screwdriver and hammer to open the hole at the top of the tank to release all of the helium entirely. Then you use a permanent marker to circle the opened hole and write "empty" next to it and then I just put it in my regular recycle bins which get picked up bi-weekly.

A: Pressurized 14.9 cu ft but in a balloon up to 27 cu ft that could be 27 11 or 12" balloons same goes for 18" foil balloons.

A: The details says 14.9 cubic feet

A: Latex balloons typically float 5–7 hours , but things like heat, humidity, balloon age and quality, and over- or under-inflation can shorten float time. It’s also important to make sure you pull the knot tight to seal the balloon. For a longer float time, use HI-FLOAT (sold separately), which coats the inside of latex balloons and helps them float longer.

A: You’ll need at least 22 cubic feet of helium. This means two large Balloon Time tanks (14.9 cu ft each) should be enough with some buffer. One standard tank will not be sufficient.

A: It will likely be just enough, but it’ll be close. If you overfill or if the foil balloons need more helium than average, you might run short.

A: Thanks for your review. To clarify, our tanks contain a helium/air mixture with not less than 80% helium, carefully formulated to float standard latex balloons for 5–7 hours and foil balloons for up to 4 days. Factors like balloon age, size, material, inflation, and even altitude can affect float performance. For even longer float times with latex balloons, use HI-FLOAT (sold separately), which prevents helium from escaping.

A: Hello and thank you for your question. Great question—and yes, helium itself doesn’t technically expire, but a few things can affect its performance over time: 🎈 Leakage: Our tanks are non-refillable and designed for one-time use. If the valve isn’t completely closed or the tank is stored improperly (like in high heat or humidity), helium may slowly leak out—even if the tank still feels full. 🎈 Pressure Loss: Helium needs a certain pressure to properly fill and float balloons. Over time, especially if the tank's been partially used and stored for a while, the pressure may drop enough that the balloons inflate—but won’t float.

A: Hello and thank you for your question. You should be fine with 1 Jumbo Helium Tank for your 18 latex + 4 foil balloons, but it will be close. If you want a safety cushion (especially if you overfill a few balloons), you might consider getting 2 tanks just in case.
