Not one of the 4 air fryer listings filed here mentions a family, a household or a number of people anywhere in its text. What they state instead is a volume, in every case, and a weight of food in 2 case out of 4. Those stated capacities run from 5 quarts to 6.5 quarts, so the figures below are what a seller committed to, and any arithmetic from there belongs to the reader.

What these listings state, and what they never mention
The four listings gathered here are the ones whose stated capacity sits in the middle of the category. Between them they state 3 different capacity figures, from the Ninja AF141 at "5 quart" up to the Ninja AF181 at "6.5 quart", with two listings sharing "6 quart" in between.
None of the 4 uses the word family, and none states a serving count. That absence is the finding, not an oversight in the record: where a listing does not make a claim, this catalog leaves the field empty rather than filling it in with an estimate. A reader converting quarts into dinners is doing something the listing did not do.
The one listing that states a load
Only 2 of these listings puts a weight beside its volume. The AF181 states "9 lbs of wings" alongside its "6.5 quart" capacity, which is the single place in this group where a stated volume is paired with a stated quantity of food.
The AF141 states "4 lbs of fries" in the wider catalog record, and that is a second kind of load again, since fries and wings do not pack alike. Two listings, two units of food, and no shared basis for putting them on one scale. The remaining pair state a volume and nothing else.
What moves with the capacity figure
Wattage is stated by three of the 4, running from 1725W to 1750W, and 1 states none. The highest of those figures is stated twice, by the smallest basket in the group and by the largest, which is to say the field does not track size here at all.
The in-one count is stated by three of them and ranges from 4 to 9. The lowest count sits on the smallest basket and the highest on a middling one, so a bigger number on the front of the box is not a bigger machine. What those counts are counting is its own question, and the listings answer it unevenly.
Reading the table instead of a recommendation
The table below carries every figure these 4 listings state on the fields this catalog tracks, with "not stated" wherever a seller stayed quiet. Maximum temperature is stated by three of them, and those claims are not all of one kind: one is a range with both ends given, the others are ceilings.
Set against the straight size comparison in the quart-against-quart version of this question, the pattern is the same. Capacity is the field sellers fill in; everything a reader would need in order to turn capacity into a household is the field they leave blank. The category index holds the rest of the listings filed under air fryers.
In this group of 4, "6 quart" is stated twice and the other two figures once each. Nothing in the listings connects any of those figures to a number of people.
Does any air fryer listing say how many people it serves?
None of these 4 does. The closest any of them comes is a weight of food: the AF181 states "9 lbs of wings", and the AF141 states "4 lbs of fries". Neither is a count of people.
Is a 5 quart air fryer too small?
The listing for the AF141 states "5 quart", a maximum of "400F", 1750W and "4 lbs of fries". It states nothing about whether that suits any particular household, and neither does this page.
What is the difference between "5 quart" and "6.5 quart" here?
On the stated fields: the capacity figure, the maximum temperature claim, and whether a load is named. Both state a wattage, and the smaller of the two states the lower in-one count. The rest of the counted fields are empty for both.

Three claims: a volume, an adjective and a coating phrase. The volume figure is shared with a listing here that also states a wattage, a temperature range, a fan speed count and an in-one figure, which is a useful reminder that a matching capacity matches only the capacity.

Four figures about the machine and one about what goes in it. The pound figure is a capacity claim measured in the contents rather than the basket, which makes it the hardest number in this catalog to line up against anything else.
