Wash your child’s bedding weekly, and that includes all sheets, blankets, pillowcases, mattress protectors and bedcovers in hot water that is at least 54.4 C, to kill dust mites and remove allergens. Vacuum carpets and upholstered furniture regularly. Only use vacuums fitted with HEPA filters to help decrease house-dust emissions from the vacuum device. When removing and reapplying bed linen avoid shaking sheets, which further disperse allergen triggers back into the air, instead fold and unfold bed sheets when removing and reapplying.
