Duvet vs. Pillow: Cleanliness and Comfort Pillows can collect sweat, oils, and dust, becoming a haven for fungi and dust mites. Wash your pillows every three months, and use protective covers that should be cleaned at least once a month for added protection.

Duvets, which are shielded by covers and less exposed to skin, only need washing about every six months. This keeps them fresh and extends their lifespan without unnecessary washing.
