When looking for the right size air popcorn popper maker, there are a few factors to consider. First, think about how much popcorn you typically make at one time. If you usually only make a small amount for yourself or a couple of people, a smaller air popcorn popper may be sufficient. However, if you plan on making larger batches for a family or group of friends, you may want to opt for a larger size.Additionally, consider the space you have available in your kitchen for storage.
