A 6.2 L air fryer has a larger stated volume than a 4.2 L model, but that difference alone cannot tell you how much food you can cook well in one batch. Basket shape, food type and the manufacturer's loading instructions matter. Compare those alongside the counter space.
Begin with a normal meal
Write down the food you would most often prepare and how much you normally need. Then look for guidance for that food and exact model. Do not assume every litre corresponds to a fixed number of people.
Some preparations depend on usable base area and how the food is arranged, not just the total space above it. Follow the manufacturer's quantity and arrangement guidance rather than filling the basket to the top to justify the capacity label.
Compare the complete footprint
Measure both appliances with the basket extended and allow their specified clearances. A larger unit may fit the same cupboard for storage while needing a different operating position. Check the weight and handling if it must be moved regularly.
Include the sink and drying area in the comparison. Larger removable parts can be less convenient in a compact washing space, even when the cooking position is adequate.
Keep the model identifiers exact
Philips identifies the NA120/00 as 4.2 L and the NA130/00 as 6.2 L. The NA120 store page also contains an inconsistent 4.1 L specification field, so confirm the current model label and manual before purchase. Compare complete model suffixes; a related overseas version may have different documentation.
Use a decision checklist
- Does the manufacturer's guidance suit your usual quantity?
- Is the basket shape appropriate to the food?
- Can the kitchen provide the required operating space?
- Are the controls and cleaning routine suitable for you?
- Is the larger model useful enough to justify its space?
Avoid capacity-based promises
This is a size-selection guide, not a tested cooking comparison. It does not establish which model cooks faster, uses less electricity or produces better results. Choose on documented fit and intended use first; leave performance claims out unless supported by relevant evidence.

A useful question before you decide
Does 6.2 L guarantee a larger meal in one batch?
The volume is larger, but useful capacity also depends on basket shape, food arrangement and the exact model’s loading guidance. Compare your normal meal against those instructions rather than assuming a fixed serving count.
