Pillows can gather oils, hair, and dirt, making them a breeding site for fungi and dust mites. Clean pillows every three months, particularly if you use protective covers, which should be washed at least monthly.

Duvets, shielded by covers and less exposed to skin, only require washing about every six months. This interval keeps them fresh while preserving their quality.
