RRC Mattress Protectors offer protection against dust mites, fluids, urine, perspiration and allergens making them especially helpful for those with kids, pets, allergies or incontinence. As we sleep we shed thousands of dead skin cells, which can quickly accumulate providing an ideal environment for dust mites. RRC mattress protectors trap dust mites, allergens and skin cells on the surface of the protector where they can be easily washed away during suggested quarterly launderings. This helps provide a cleaner more allergen free sleep environment for you and your family.
