Here's what we look for:
- Food-contact interiors made from stainless steel or glass
- No plastic where it touches food (but we avoid plastic wherever possible)
- Updated microwave tech with inverter technology and triple-layer door seals to reduce EMFs
- Transparent brands that disclose all materials

How to Swap to Non-Toxic microwaves:
Here's how to swap to non-toxic microwaves:
What to know about microwaves
Welpr focuses on what the inside of your microwave is made of, since that's the surface in direct contact with heat and your food. We also consider overall design and shielding, since proper construction helps minimize unnecessary EMF leakage.
- Most microwaves have painted or coated steel interiors, but some use stainless steel or ceramic enamel, which are more inert and less likely to degrade over time.
- The turntable is a key contact point — glass is the safest option, while plastic trays or covers used inside the microwave can be a concern.
Review the microwave you already have
Check your microwave's interior material and the condition of its coating. Also look at the turntable and any accessories that came with it, like plastic covers or racks.
- If the interior paint or coating is chipping, peeling, or rusting, that's a sign the surface is breaking down and may be releasing material into your food environment.
- Remove any plastic trays, covers, or splatter guards that came with the microwave and replace them with glass or ceramic alternatives.
Use your current microwave more safely
Even if your microwave isn't ideal, a few simple changes can reduce direct contact between food and less-than-ideal materials. What you put inside the microwave matters just as much as the microwave itself.
- Always heat food in glass, ceramic, or stoneware containers — never in plastic, even if it's labeled "microwave safe."
- Cover food with a ceramic plate or glass lid instead of plastic wrap or plastic splatter covers.
Choose a cleaner replacement
When you're ready for a new microwave, look for stainless steel or ceramic enamel interiors, a glass turntable, inverter technology, and triple-layer door seals. These materials are non-reactive, and the design helps heat food evenly while limiting unnecessary EMF leakage.
- Avoid models with plastic interior components or painted coatings that can chip — stainless steel interiors are the most durable and inert option available.
