If you want a large, high-heat fiberglass liner set built specifically for the Breville Smart Oven Air Fryer Pro BOV845BSS, choose SIUDANGKA 4PCS; if you need a cut-to-fit silicone liner-and-mesh kit that also suits the BOV900BSS, Ninja Foodi and other ovens, choose JAYOBGO Reusable Air Fryer.
• SIUDANGKA 4PCS — biggest strength: four large 12.5" x 19" fiberglass liners rated to 500°F, sized to sit on the oven floor of the Breville BOV845BSS.
• SIUDANGKA 4PCS — biggest trade-off: a fixed 12.5" x 19" rectangle for a specific oven model, so it is not the pick if you want to trim a sheet down for a smaller basket or a different brand.
• JAYOBGO Reusable Air Fryer — biggest strength: a 6-piece kit (3 liners + 3 mesh pads) in food-grade silicone that you can cut to size, dishwasher safe, and rated for use below 450°F.
• JAYOBGO Reusable Air Fryer — biggest trade-off: the smaller 13" x 9" footprint per piece and the lower 450°F ceiling mean it is not the one to grab for very high-heat roasting on a big oven floor.
• Pick SIUDANGKA 4PCS if you own the BOV845BSS and want the floor protected with the least fuss.
• Pick JAYOBGO Reusable Air Fryer if you own a BOV900BSS, a Ninja Foodi or several different ovens and want one kit that adapts.
This is a specialist, not a generalist. The four liners measure 12.5 inches by 19 inches each — a long, wide rectangle that matches the floor of the Breville Smart Oven Air Fryer Pro BOV845BSS. That size is the whole point. Instead of fiddling with something that slides around or leaves gaps at the edges, you lay a sheet down and the drips, crumbs and grease land on the mat instead of baking onto the oven floor. You get four of them, so one can be in the oven, one in the sink and two in the drawer. For anyone who air fries or roasts several times a week in that specific Breville, that rotation matters more than any single clever feature.
The material is fiberglass with a non-stick surface, and the sheet is rated to withstand temperatures up to 500°F. The brand also states it is BPA and PFOA free, and free from lead and cadmium — the kind of labeling people look for when the liner is going to sit under food at high heat. It is thin and light (about 0.14 kg for the set), so it does not meaningfully change how the oven heats, and it can be used directly as a cooking surface, or as a drip pan, baking mat or BBQ grill mat rather than only as a floor protector.
Where it is less ideal: the fixed size. If you own a different oven, a smaller toaster oven or an air fryer with a pull-out basket, a 12.5" x 19" sheet is simply the wrong shape, and there is nothing in the specs suggesting it is meant to be trimmed. The instructions also warn to keep it away from direct contact with heating elements and open flames, and to place it on the lowest tray or grill if your oven has hidden elements. Follow that and it does its job quietly. In my opinion this is the pick for a BOV845BSS owner who wants a big, dedicated floor liner and does not want to think about it again.
JAYOBGO takes the opposite approach: smaller pieces, more of them, and more flexibility. You get six items — three liners and three mesh pads — each 13 inches by 9 inches (listed as 12.99 x 9.13 inches). That is a much smaller footprint than the SIUDANGKA sheet, which is exactly why it works in more places: the brand lists compatibility with the Breville Smart Oven Air Fryer Pro BOV900BSS, Ninja Foodi, and Breville, Emeril Lagasse and microwave baking or grilling setups, and the liner can be cut to size to fit the bottom of an oven, square or otherwise.
The material here is food-grade silicone, described as non-toxic and BPA-free, with heat and corrosion resistance — but with a clear ceiling: use it below 450°F / 232°C. That is a real, practical limit worth respecting. Air frying and everyday baking sit comfortably under it; aggressive high-heat roasting or broiling does not. The upside of silicone is the cleanup story. Grease does not stick, dough does not weld itself to the surface, and both the liners and the mesh pads are reusable and dishwasher safe. The mesh pads are the underrated half of the kit — useful for letting air and fat pass through while keeping food off the surface.
Who should skip it? If you want one big, no-cut sheet that blankets an entire oven floor, this is not that product. And if your cooking regularly runs hotter than 450°F, you would be pushing past the stated limit. For a household with more than one oven, a Ninja Foodi in the cupboard and a toaster oven on the counter, though, having six trimmable silicone pieces is genuinely more useful than four big fixed ones. In my opinion it is the better fit for a mixed-appliance kitchen or for anyone who hates scrubbing.
Side-by-Side: Which Should You Choose?
• Best for Breville BOV845BSS owners → SIUDANGKA 4PCS. The 12.5" x 19" size is built around that oven.
• Best for high-heat cooking → SIUDANGKA 4PCS. Up to 500°F versus a stated limit below 450°F for the silicone.
• Best for trimming to a custom shape → JAYOBGO Reusable Air Fryer. The liners can be cut to size; the SIUDANGKA sheet is a fixed rectangle.
• Best for easy, dishwasher-safe cleanup → JAYOBGO Reusable Air Fryer. Silicone plus mesh pads, both dishwasher safe.
• Best for covering a large oven floor in one go → SIUDANGKA 4PCS. One wide sheet, no seams or gaps.
• Best for getting more pieces → JAYOBGO Reusable Air Fryer. Six items (3 liners + 3 mesh) versus four liners.
• Best for a single-oven, low-effort routine → SIUDANGKA 4PCS. Drop it in, wipe it down, swap to the next one.
If I owned a Breville Smart Oven Air Fryer Pro BOV845BSS and wanted the simplest possible protection for that oven floor — big coverage, a 500°F rating, four sheets to rotate — I would buy the SIUDANGKA 4PCS. If instead I had a BOV900BSS, a Ninja Foodi, or more than one oven to feed, I would buy the JAYOBGO Reusable Air Fryer, because six trimmable, dishwasher-safe silicone pieces simply fit more situations. My honest recommendation for the widest range of buyers is JAYOBGO; my recommendation for the one-oven, high-heat cook is SIUDANGKA.
It comes down to the model. SIUDANGKA is sized for the BOV845BSS, while JAYOBGO lists the BOV900BSS — so match the liner to the exact oven you own.
Yes. The brand states the 13" x 9" liners can be cut to size to fit the bottom of an oven, square or other shapes. The SIUDANGKA sheet is a fixed 12.5" x 19" rectangle.
SIUDANGKA says up to 500°F. JAYOBGO says to use its silicone liners below 450°F / 232°C. If you often cook hotter than that, choose the SIUDANGKA set.
JAYOBGO states its liners and mesh pads are reusable and dishwasher safe. SIUDANGKA emphasizes the non-stick, easy-wipe surface but does not list dishwasher use — I would hand-wash those to be safe. Either way, check the current price on Amazon before you decide.
