Many microwave covers include vented or perforated lids that let steam escape; some descriptions note perforations that also allow the cover to double as a colander for rinsing fruits or vegetables.
Microwave egg cookers are described to heat and cook multiple eggs at once—for example, one model cooks up to four eggs and uses a snap-on lid to lock in steam for more even cooking.
Common materials include silicone (often labeled 100% food‑grade), various plastics (including melamine‑free options), TPR (thermoplastic rubber), polypropylene, and some products that incorporate an aluminum insert.
Many covers are sized to fit standard dinner plates, with diameters and overall widths commonly in the ~10–12.25 inch range; several listings explicitly state they fit plates up to 11 inches in diameter.
Several covers are designed to collapse for compact storage—some collapse to about 1 inch high—and listings may also mention magnetic attachments and vented, collapsible lids for easy use.
Warranty lengths shown range from short limited warranties (for example, a 30‑day limited warranty) to longer limited warranties (for example, a 5‑year limited warranty).
