Weather dust collector

Dust will definitely get into the quilt cover. See if you value it or not. Be careful to wash it before putting it on, and then expose it to the sun after being accidentally photographed, but I don't agree with what you said about bacteria. In fact, all quilt covers are mites, and the so-called "quilt smell" you smell in the sun is actually the smell of mites' corpses dried in the sun. There is no suggestion to wash the quilt cover or quilt. In fact, exposure can kill most harmful bacteria without washing. If you stay in the sun for more than 2 hours, you can solve many problems. Life doesn't have to be so stubborn, does it?
