Air Fryer Accessory Compatibility Chart: Sizes by Brand at a Glance

Your air fryer accessory must match basket shape and usable interior, not quart rating alone. As a guide, 3.5–4-quart round baskets often suit 6-inch pieces; 5–6-quart baskets often suit 7-inch pieces.

Cosori’s seven-piece kit targets 5.8-quart baskets, while Philips accessories are model-specific and Ninja DZ201/DZ401 kits require exact-model checks.

Measure each item’s full footprint and height, allow about ½ inch side clearance, and verify divider, handle, heating-element, and drawer clearance. The chart below narrows choices.

Brand-Specific Fit at a Glance

Accessory fit depends more on basket dimensions and model design than on quart rating alone: start with 6-inch pieces for 3.5–4 qt round baskets and 7-inch pieces for most 5–6 qt baskets, then check measurements and leave about ½ inch of clearance. Capacity labels don’t establish identical interiors, so compare each accessory’s outer diameter with your basket’s widest interior point before ordering. The Cosori seven-piece kit targets 5.8-qt baskets and many comparable 5–6-qt units but won’t fit a 4-qt Instant Vortex.

Ninja Foodi DZ201 and DZ401 dual baskets typically need model-specific pieces; their listed ten-piece set isn’t for single-basket fryers. Philips also uses family-specific compatibility: HD9911 fits HD924x, while HD9940 fits HD962x and HD964x. Verify the complete model number, not just brand.

Brand-by-Brand Accessory Fit Chart

Brand fit varies by basket shape, dimensions, and model series—not just capacity—so compare the maker’s compatibility list with your exact model number.

For Philips, don’t assume an XXL accessory fits Essential; check its manual, since Philips cautions against parts that obstruct airflow or approach the element. Cosori’s square-basket platforms vary by series, so match the model listing rather than capacity alone.

A multi-size kit may cover tiers, but “universal” isn’t a fit guarantee. Measure the accessory’s dimensions against your appliance, then confirm drawer clearance and temperature rating before use.

Basket Shape Compatibility

Although capacity labels may match, basket shape determines whether an accessory fits: round, square, oval, and dual-basket designs aren’t interchangeable. Round baskets are most common. To estimate the largest accessory that preserves airflow, measure the widest interior diameter and subtract ½ inch.

Square-basket accessories won’t necessarily fit a round fryer of equal capacity. A 10-piece Cosori set, for example, targets square baskets; don’t assume it suits every model.

Oval baskets and dual-basket units may also require model-specific accessories. Ninja Foodi DZ baskets generally need pieces designed for those baskets, rather than standard single-basket inserts.

For oven-style fryers, match cookware to the cavity’s interior dimensions and leave airflow clearance. Before buying, compare the accessory’s shape with your basket and verify usable dimensions. Capacity alone can’t confirm compatibility; the basket’s geometry determines whether cookware sits securely and allows circulation.

Accessory Dimensions by Model

Compare your basket’s usable interior dimensions, not its advertised capacity: 3.5 to 4 qt round models often suit 6-inch accessories, while 5 to 6 qt models commonly fit 7-inch pieces. Brand and model geometry still varies, so check dimensions, for example, a 7-inch Cosori pan won’t fit a 4 qt Instant Vortex, and Ninja dual-basket accessories are model-specific. Before buying, measure the widest interior span and allow about ½ inch of clearance; also verify accessory height, handles, and feet.

Basket Interior Measurements

To size an accessory, measure the basket’s widest interior diameter and subtract about ½ inch for clearance and airflow. Use capacity only as a rough filter: a 3.5–4 qt basket commonly fits 6-inch accessories, while 5-6 qt baskets often take roughly 7-inch pieces; larger round baskets may accommodate 7- or 8-inch accessories.

Still, measure usable length, width, and height, including clearance below the heating element. Handles, feet, and other projections can block insertion or drawer closure. The Cosori 7-piece kit’s 7-inch pans suit 5.8-qt and similar 5–6 qt baskets, but they’re too large for a 4-qt Instant Vortex. Check your exact model and basket shape before buying: Ninja Foodi dual-basket accessories are often model-specific, while some Philips accessories are intentionally smaller than the basket.

Brand Size Differences

Accessory dimensions vary by brand and model, even when basket capacities match. For 3.5–4 qt baskets, 6-inch accessories are typical; 5–6 qt units commonly take 7-inch pieces. Capacity alone doesn’t confirm fit: measure the widest interior diameter and leave about ½ inch for airflow. Some larger round baskets may need 8-inch accessories.

Brand ranges also differ by shape and kit design. Cosori’s 7-piece kit targets 5.8-qt baskets, while its square-basket set covers 5.8- and 6.8-qt models plus similar square units.

Philips accessories aren’t interchangeable across capacity labels: its HD9925 fits several series but is smaller than baskets in some larger models; HD9909 muffin cups fit nine at once. Ninja Foodi dual-basket models use model-specific parts, and each basket may need a distinct accessory. Check exact fit before you buy.

Model-Specific Dimensions

Even within the same capacity range, accessory dimensions and model compatibility can differ substantially. For round baskets, measure the widest interior diameter, then choose an accessory about ½ inch smaller to preserve clearance. A 6-inch pan suits a 3.5-4 qt model, while many 5-6 qt baskets take 7-inch accessories.

The Cosori seven-piece kit uses 7-inch pans for 5.8 qt baskets; it won’t fit a 4 qt Instant Vortex. Its square-basket kit measures 9.45 × 9.45 × 5.91 inches and lists Cosori 5.8/6.8 qt and Instant Vortex Plus 6 qt models, but check dimensions. Philips HD9925 fits HD9216/17, HD922x, HD923x, HD953x, HD962x, and HD964x families; on HD924x, HD963x, and HD965x, it’s smaller than the basket. Ninja’s 17-piece set targets DZ401 and DZ201; liners match 5 qt and 6 qt baskets.

Usable Cooking Space

How much cooking space an accessory actually uses depends on its dimensions, not just the fryer’s quart rating. For round baskets, compare the accessory’s diameter with the widest usable interior diameter; a piece about ½ inch smaller leaves room for airflow. As a starting point, choose 6-inch accessories for 3.5–4-quart baskets and 7-inch pieces for many 5–6-quart models. Round baskets of 6 quarts or more may accommodate 7–8-inch accessories, but capacity alone won’t confirm fit.

Model examples show why dimensions matter. Cosori’s 7-piece kit has 7-inch pans for 5.8-quart and similar baskets, but those pans are too large for a 4-quart Instant Vortex. Its square-basket set measures 9.45 × 9.45 × 5.91 inches; check usable width, height, and heating-element clearance. Gourmia’s 7-inch liners suit specified 7- and 8-quart baskets, not every fryer in those tiers.

Measuring Before Buying

Before buying, measure the fryer’s widest usable interior diameter and subtract about ½ inch for clearance and airflow; quart capacity alone won’t confirm fit. Check your exact model and basket shape, then measure usable length, width, and height, including clearance beneath the heating element. Compare those measurements with each accessory’s outer dimensions, not its advertised capacity tier.

Include projecting feet, handles, rolled edges, and skewer ends; they can prevent stable placement, drawer closure, or safe element clearance.

As a starting comparison, 3.5–4 qt baskets often suit 6-inch pieces, while 5–6 qt baskets often suit 7-inch pieces. Larger round baskets may accept 7- or 8-inch accessories, but verify your model’s dimensions. Measure every item in a kit separately: Cosori’s 7-inch pans target 5.8-quart and similar 5–6 qt baskets, so they may not fit a 4-quart fryer. Use manufacturer fit lists when available, but treat measured clearance as the final check.

Measure Your Basket’s Interior

Measure the basket’s usable interior—not its outside rim—to determine accessory fit. For a round basket, record the widest usable interior diameter, then subtract ½ inch from that measurement. This allowance helps keep an accessory from binding against the sides and preserves space for airflow.

With a square or oval basket, measure usable interior length and width instead; compare the flat cooking area, not the maximum edge-to-edge span. Check corners, handles, and ridges that may narrow the surface available to support a pan or rack. Measure usable height too, including clearance below the heating element. Account for accessory feet, handles, and raised edges when checking vertical fit. Finally, consult your appliance manual and the accessory’s dimensions: quart capacity alone can’t confirm fit, stability, or airflow.

Dual-Basket Divider Clearance

For a dual-basket fryer, check each basket’s usable width and height, including the divider, because matching the listed quart capacity doesn’t guarantee clearance. Measure the accessory’s full footprint, including rims, feet, handles, and skewer ends, then compare it with the space on both sides of the divider. A wide insert that fits one basket may rub the divider or stop the opposite drawer from closing.

For Ninja Foodi dual-basket models, verify the exact model, such as DZ401 or DZ201; a universal kit’s size range doesn’t confirm fit. Test the accessory in the cool fryer. It should sit stably without touching the divider, blocking vents, or obstructing drawer removal. Leave room around food for airflow: adding a rack or crowding either basket can restrict circulation, so added layers don’t necessarily increase usable cooking capacity.

Handle Clearance for Inserts

Even when an insert’s base fits, protruding handles or tabs can make it too wide for the basket. Measure the basket’s usable width and length, then compare them with the insert’s full outer dimensions, including every projection. A round base may fit where a tabbed silicone liner doesn’t; the tabs count toward total width.

Leave side clearance so the insert sits flat without scraping the walls or catching the drawer. A close fit can prevent closure, while excessive movement can make the insert unstable.

Before cooking, test the insert in the cool fryer. Confirm it rests level, doesn’t rattle, and slides in and out without catching. Check that handles stay clear of the heating element and don’t obstruct safe removal. Base diameter alone won’t confirm compatibility; overall width and handle position matter.

Accessory Height Clearance

Once an insert clears the basket walls and drawer, check its vertical fit: compare its full loaded height, including feet, handles, rims, and stacked food, with the space from the basket floor or crisper plate to the heating element. A width-compatible pan can still sit too high; check the exact model’s usable clearance, not basket capacity alone.

1. Seat the accessory level; confirm feet and handles remain below the element.
2. Load food as planned; stacked portions count toward total height and must stay clear.
3. Test drawer closure; verify stable placement and airflow, since a second rack may crowd the upper tier.

Philips HD9925’s smaller footprint in HD924x, HD963x, or HD965x baskets proves neither vertical clearance nor safe spacing; assess height separately before cooking each time.

Brand Model Number Cross-Check

A capacity match alone won’t confirm accessory fit; check your fryer’s complete model number against the accessory’s compatibility list. Brand, product family, and quart rating can conceal different basket geometries and parts. Match replacement baskets, drawers, trays, and crisper plates to the exact model; dual-basket units may require distinct left- and right-side components.

1. Find the accessory number, then compare its listed model range with your fryer’s full code.
2. For example, Philips HD9925 lists HD9216/HD9217, HD922x, HD923x, HD953x, and HD962x series.
3. Don’t infer that another rack fits: HD9904 covers specified earlier series, while HD9905 targets HD924x, HD963x, and HD965x.

Confirm both against the manufacturer’s parts catalog or manual; a capacity-only marketplace claim offers weaker evidence. Check suffixes and variants before ordering, especially for replacement assemblies.

Conclusion

Before buying, match your air fryer’s brand and exact model number to the chart, then compare the accessory’s dimensions with your basket’s interior. Check shape, divider clearance in dual-basket models, handle space, and usable height; nominal capacity alone won’t confirm fit. When two accessories appear compatible, choose the one with safer clearance rather than a tight fit. You’ll reduce the risk of blocked airflow, difficult handling, and returns by checking measurements before ordering.
