When searching for products on the Bargain Balloons website, you may come across descriptions that read 'Airfill only'. These particular products should only be inflated with air because, if you inflate these balloons with helium they will not float.
Please Note: Almost all 'Airfill Only' balloons require heat-sealing. See the article How to Heat-Seal Airfill Balloons.
The following list of balloons will not float with helium:
- Mini/micro balloons (balloons needing a stick and cup)
- Letter and number balloons (16-inch and smaller)
- Many script letter balloons
- Sitting Balloons
- Inflate-A-Fun Balloons
- Selfie Frame Balloons
