Buyers must read this, newbies must read this! Very important!! (The packaging may occasionally change, but the contents remain the same. Existing customers, please note that the bottle is marked as 13L, but due to the reason of ...High compression, still 50 balls, equivalent to a large can of non-compressed 22L! Please be informed!）

This type of helium tank is a disposable item. Once the buyer has opened and used it, it cannot be resold, and therefore, no exchanges or returns will be processed! This is the industry standard practice, and by placing an order, you are deemed to have accepted this term. In some areas, the courier service may not deliver, so please clearly inquire before placing an order.

Please carefully read our product description before purchasing.

If you have any questions, please contact customer service to answer questions before you make a purchase.

 Problem one: The purchase does not meet the expected, and the cost of a single ball after inflation is about seven or eight yuan! It's too expensive!

Answer: Helium, as a non-explosive and non-toxic lifting gas, is a star gas. Its extraction is extremely difficult, resulting in high natural costs. Those who cannot accept this should be cautious!

Question 2: I'm dizzy, I just inflated a few balloons and they're already flat! Are you trying to cheat me, boss?
Answer: The number of balloons that can be inflated is described in the following table. Please refer to the comparison! Additionally, please do not claim that balloons of very large sizes cannot be inflated, as the gas is limited and the balloon sizes are diverse! Please carefully understand the table before inflating!

Question 3: Why did my gas bottle become heavier after using up the helium? Is it because you guys are dumping helium waste?
Answer: Because helium is a lighter-than-air gas with a lower density than air, it exerts an upward buoyancy force on the bottle when it is inside. This makes the bottle feel lighter. After the helium is released, the bottle will feel heavier, which is not unusual.

Question 4: The number of inflatable balloons (important)

Answer:

13L small bottle of helium: at room temperature, it can inflate about 30 10-inch latex round balloons, about 25 12-inch latex round balloons, and about 7 18-inch aluminum foil balloons.

22L large bottle of helium: Under normal temperature, it can inflate about 50 10-inch latex round balloons, about 35 12-inch latex round balloons, and about 12 18-inch aluminum foil balloons. The above data is based on theoretical measurements for a single type of balloon. It does not mean that the total number of balloons can be inflated. Novices may waste some air if they are not good at estimating, so the number of balloons to be inflated should be less than the theoretical data.

General latex balloons float for about 6 hours, while latex balloons made of aluminum foil will float for a longer period. For events, birthday parties, wedding decorations, it is recommended not to inflate them too early to avoid the gas escaping.

How long can a balloon inflated float? Answer: The floating time depends on the weight of the balloon. General latex balloons can float for about 5 hours. For events, parties, birthday, wedding decorations, it is recommended not to inflate the balloon too early to avoid the gas escaping. You can inflate the balloon 30 minutes or 1 hour before the event, and make sure to fill the gas fully.

Why is the helium from your company cheaper than others? Answer: Our store is a direct manufacturer, eliminating the intermediary link, directly benefiting the vast majority of customers! @Dear customers, you can rest assured to purchase.

Is helium safe? Is it toxic? Is it flammable or explosive? Answer: Helium is a colorless and odorless gas that cannot be ignited. It has no chemical activity and does not combine with other elements or compounds under normal conditions. It can theoretically be separated from air, but because its content is too sparse, helium is separated and refined from natural gas containing about 0.5% helium. Helium, HELIUM, comes from helios, which means "sun," and was discovered in 1868. Almost all the helium in the world is extracted from gas wells in the United States. It is lighter than air and is widely used in airships and balloons to replace the highly flammable hydrogen. Liquid helium is a treasure of cryology because its boiling point is particularly low!
