Our magnets are specially designed not to arc through their rounded shape, which means they are 100% safe to use in the microwave.

We all know that you can’t and shouldn’t put forks in the microwave, either because we’ve been told not to or because we found out the hard way what happens when you do. However, it’s a complete myth that you can’t put any metal in microwaves. Here’s why:

Metal reflects waves, which is why the walls of your microwave are made out of special metal – so the waves can bounce around inside your microwave, where they belong. Sometimes, however, when you combine lots of pieces of metal together (like the prongs of a fork) or metal with very thin or sharp edges, this can cause sparks to fly. This is due to something called arcing² – when electrons flow from a more negatively charged surface to a less negatively charged surface, if you want to get scientific.

All that to say, Duo Cover specifically designed our magnet to be 100% microwave-safe so you can have total peace of mind.

All microwaves are basically steamers already. They excite the H₂O molecules in your food, generating steam — which then rises and pushes against your Duo Cover’s MoistureLock™️ knob. This then creates a tiny gap allowing the water you add to the top of your Duo Cover (if you want to – this step is optional) to be slowly added to your food, keeping it moist. In other words, Duo Cover simply traps the moisture your microwave already creates, producing steamed meals that taste much better than when you use your microwave without it.

Duo Cover is 11” in diameter and fits most microwaves, including small models.

No! In fact, some studies have shown that microwaved food is even more nutritious than regular food. Because it cooks so quickly, the food has less time under heat, leading to less nutrient loss. I swear we’re not just making this up to sell Duo Covers. For more information, check out these studies from the American Dietetic Association and Critical Reviews in Food Science and Nutrition.
