Duvets and Pillows: Cleanliness and Allergen Control

Pillows collect oils, hair debris, and moisture, becoming favorable for fungi and mites. Launder every three months. Protective pillow covers should be washed at least monthly to extend pillow life.

Duvets are shielded by covers and experience less direct contact. Wash the duvet about every six months, while washing the removable cover more frequently according to use (often every two to three weeks).
