Pillows can accumulate oils, hair, and dirt, creating environments for fungi and dust mites. Clean pillows every three months, particularly when using protective covers, which should be washed at least monthly.
Duvets, shielded by covers and less exposed to skin, require washing only about every six months. This schedule maintains freshness while preserving their quality.
