No brand pays for placement or higher scores.

Not every family has a spacious kitchen with unlimited counter space. Compact air fryers (2-4 quart capacity) are designed for small kitchens, apartments, dorm rooms, RVs, and as a secondary appliance. The challenge: smaller models often use cheaper materials and coatings because they target the budget market. R3 applies the same safety and performance standards to compact models as we do to full-size units, ensuring you don't sacrifice quality for size.
How this compact list differs
This list filters for models suitable for small kitchens (compact footprint, typically under 5 quarts), ranked by overall score. Our main guide includes all sizes.
See all Best Lunch Box picksThe compact air fryer segment is the fastest-growing category, driven by apartment dwellers, college students, and families who want a secondary unit. But "compact" often correlates with "budget," and that is where safety concerns emerge.
Our testing found that compact models are twice as likely to lack UL/ETL certification compared to full-size units. Some use unspecified non-stick coatings to hit a $30-40 price point. R3 applies identical Material Safety and Product Safety scoring to compact models, which is why several popular budget compact units don't appear on this list.
The good news: several manufacturers now offer compact versions of their premium lines with the same ceramic or stainless steel baskets used in full-size models, just in smaller dimensions. These are the picks that made our list.
Use this checklist when evaluating any lunch box for compact criteria.
Look for
Avoid
Compact air fryers range from 8x8 inches to 12x12 inches. Measure your available counter space (including height under upper cabinets) before shopping.
Compact models (2-4 quarts) serve 1-2 people per batch. If you regularly cook for more, consider a mid-size model instead of running multiple small batches.
Several compact models use the same ceramic or stainless steel baskets as their full-size counterparts. R3 verifies material quality regardless of size category.
Compact models can be louder per-quart because the fan is closer to the food. If noise matters (apartment living, open kitchen plans), check R3's noise ratings.

Best deals
Amazon Prime Day (July) and Black Friday (November) typically see 25-40% discounts on lunch box. Major brands like Ninja, Cosori, and Instant Pot participate in both events.
New model releases
Brands typically release new lunch box in Q1 (Jan-March) and ahead of holiday season (September). Previous-generation models drop in price when new ones launch.
Avoid full price
April-June and August are typically full-price months for lunch box. If you need one during these months, check manufacturer refurbished options for 20-30% savings.
R3 tip
Price drops do not change our safety scores. A discounted lunch box with a low safety score is still not recommended. Always check the R3 score before buying, regardless of the deal.
