Pillows can accumulate oils, hair, and debris, creating breeding environments for fungi and dust mites. Clean pillows quarterly, particularly when using protective covers, which need monthly washing minimum.
Duvets, shielded by covers and less skin-exposed, require washing approximately every six months. This timing maintains freshness while preserving quality.
