How do you choose which balloons to buy for your event? Both latex and foil balloons can be filled with either helium or air and both come in a variety of shapes, sizes, and colors. Here are a few things to consider when deciding whether to go with helium-filled or air-filled balloons.
Float Time
Helium is less dense than air so helium-filled balloons typically rise higher than air-filled balloons and float effortlessly. That makes helium a good choice if you want dramatic party decorations like a bunch of balloons floating over each table. Float time for helium-filled latex balloons is about 8-10 hours (longer if treated with Hi-Float). Float time for helium-filled foil or Mylar balloons is usually about three to four days. Some balloon brands can stay inflated for up to three weeks. Air-filled balloons don’t really float but they look great taped to the ceiling with ribbons and are excellent for building balloon arches.
Cost
Helium-filled balloons can be more expensive than those filled with air. However, they last much longer and are easily refillable, providing better value.
Variety
Both types of balloons can be customized for your event with messages, graphics, and designs. Helium-filled foil (Mylar) balloons are available in a much wider range of shapes like cartoon characters, dinosaurs, and princesses than those available for latex balloons.
Refilling
Foil (Mylar) balloons filled with helium can easily be refilled with more helium once they start to deflate. Once you fill a latex balloon with air and tie it off, the balloon cannot be refilled. If you need lots of balloons, renting a helium tank can cost less than buying pre-filled balloons. If you rent or buy helium tanks, you can get cost-effective refills and keep your decorations looking great.
