Description Luna's exclusive waterproof mattress protectors are extremely popular for their ability to breathe, operate silently and provide premium protection from dust mites, allergy triggers and fluids. Luna's hypoallergenic mattress protectors not only protect your mattress from stains and fluids, but also prevent dust mites, bacteria and fungus from penetrating into your mattress where health adverse issues may arise. Luna premium mattress protectors are designed to provide a healthier environment using an advanced terry cotton bonded membrane material that is completely silent, hypoallergenic, waterproof and breathable. The ability of Luna's barrier material to breathe prevents heat buildup that often leads to sweating. A Luna premium mattress protector is a must have for those suffering from allergy triggers such as pollen, mold, dust mites and fungus. They are effective in preventing 99% of allergy triggers from penetrating through the membrane cover while still allowing the mattress to breathe. Periodically wash the mattress protector, like you would you sheets, and you’ll be able to remove allergy causing triggers that may be resting on the surface of the protector. Luna protectors make for a more sanitary and healthier nights sleep.
