Choose Aeroccino 3 if you want the simpler Nespresso milk frother for hot milk foam, cold foam, and hot milk. It is best if you mostly make basic cappuccinos, occasional iced coffees, or warm milk drinks and you do not need different foam textures.
Choose Aeroccino 4 if you want more milk-drink flexibility. It commonly offers four preparations: cold milk foam, airy hot milk foam, dense hot milk foam, and hot milk. It is also listed as dishwasher safe on many official Nespresso pages, which makes it easier to live with if you froth milk often.
Neither Aeroccino brews coffee or uses capsules. They are accessories. You can pair them with Nespresso Original machines, Vertuo machines, or other coffee setups. Your coffee machine still determines whether you use Original or Vertuo capsules.

Aeroccino 3 and Aeroccino 4 are not coffee machines. They do not use Nespresso capsules, and they do not change capsule compatibility.
If you pair an Aeroccino with a Nespresso Original machine, the coffee still comes from Original capsules. If you pair it with a Vertuo machine, the coffee still comes from Vertuo capsules. The frother only prepares milk or milk foam.
This matters because users often confuse accessories with machine systems. Aeroccino accessories are system-neutral, but the machine beside them is not.
Aeroccino 3 is the straightforward choice. It is designed for users who want quick milk froth without thinking about texture levels.
It works well for a classic capsule-machine setup: brew espresso, froth milk, combine. That is enough for simple cappuccino, latte-style drinks, hot milk, and cold foam for iced recipes.
It is also a good choice if you do not make milk drinks every day. If you only froth milk a few times per week, the simpler design is not a problem.
The main limitation is control. Aeroccino 3 does not give the same choice between airy hot foam and dense hot foam that Aeroccino 4 commonly offers. If you are particular about foam texture, you may outgrow it.
Aeroccino 4 is the better option for variety. The key upgrade is multiple recipe buttons and more texture choice.
The ability to choose airy hot foam or dense hot foam is useful. Cappuccino usually works better with a thicker foam. Latte-style drinks often benefit from a smoother, less stiff texture. Cold foam is useful for iced coffee recipes.
Aeroccino 4 is also easier to recommend for frequent milk users because many official Nespresso pages list it as dishwasher safe. Even if you still prefer hand washing, that makes the cleaning story stronger than Aeroccino 3.
The trade-off is simplicity. If you only need one basic foam setting, Aeroccino 4 may be more than you need.
The capacity difference is not the main reason to upgrade. Both models are commonly listed with about 120 ml for milk foam and 240 ml for hot milk.
That means both are mainly single-serve or small-household frothers. They are good for one large milk drink or two smaller cappuccino-style drinks, depending on recipe and cup size. They are not large family-size milk pitchers.
Aeroccino 3 is usually simple to rinse by hand, but it is commonly not dishwasher safe. That means you should clean it carefully after milk use and avoid letting milk residue dry inside.
Aeroccino 4 is commonly listed as dishwasher safe on many official Nespresso pages. This makes it easier if you use milk every day. Still, always check the local manual and temperature guidance before putting parts in a dishwasher.
For both models, cleaning matters. Milk residue affects smell, foam quality, and hygiene. Rinse soon after use and follow the official care instructions.
Choose Aeroccino 3 if you want a simple, compact, one-button frother. It is enough if you mostly make basic cappuccino foam, hot milk, or occasional iced coffee foam.
It also makes sense if you want a lower-complexity accessory to pair with an Essenza Mini, Pixie, CitiZ, Vertuo Pop, or Vertuo Next.
Choose Aeroccino 4 if you care about foam texture and drink variety. It is better if you regularly make cappuccino, latte macchiato, flat white-style drinks, iced coffee with cold foam, or hot milk drinks.
It is also the stronger pick if dishwasher-safe cleaning is important to you.
Availability, colors, bundles, plug type, voltage, accessories, and exact dishwasher guidance vary by country. Some Nespresso machines may be sold in bundles with Aeroccino 3 or Aeroccino 4. Do not publish price, stock, discount, rating, review, or warranty claims without local verification.
