The average person perspires up to two litres of moisture a night. PureCare® helps you to keep that moisture out of your sleep environment with waterproof mattress protectors, mattress encasements and pillow protectors. PureCare carries a class one medical device rating (in the USA) on their mattress and pillow protectors, including their OmniGuard® Advance™ and PureCare mattress and pillow covers, to ensure that their products are completely moisture and waterproof. PureCare's OmniGuard® Advance fabric provides a “single micron” barrier that protects your mattress and pillow from moisture that could enter and trigger the growth of mould and mildew. MiteTight® Seams ensure that moisture can not pass through the seams of PureCare's waterproof mattress and pillow protectors, and locking zippers on all mattress encasements and pillow protectors keep the moisture out. Experience Comfort and Health. Redefined® with PureCare waterproof mattress covers and pillow protectors.
