A collection of non-sterile devices including, but not limited to, a bed sheet(s), pillowcase, duvet cover and mattress cover, intended to be used to provide cover/protection to a bed and associated items. The components are treated/impregnated with an antimicrobial substance to control bacterial and fungal growth on the fabric and reduce the levels of house dust mites (HDM) and their allergen-containing faecal droppings. The device is typically made of a thin-textile or reinforced-paper material, to be used in the home or healthcare facility. This is a reusable device.
