Purecare’s Cooling FRÍO® Pillow Protectors provide ultimate cooling relief for your guests and the highest level of protection for your pillows. FRÍO® rapid-chill cooling fibers disperse body heat, cooling 5x faster than traditional polyester for a refreshing sleep surface. The whisper-quiet, breathable protector provides 360° of protection for any pillow type without altering comfort. Our patented AirXchange® filter allows for air to flow freely to avoid ballooning around the pillow while blocking even the smallest particles. The locking zipper and double-bound MiteTight® seams offer an effective physical barrier against bed bugs, moisture, allergens, dust mites, stains, mold, and mildew for a more hygienic sleep surface. This award-winning pillow protector is Vartest® certified to block viruses as small as 32 nanometers in diameter and is Crib 5 fire retardant. Our performance fabric is designed to be washed and dried on hot settings (up to 200°F/93°C) for optimal sterilization or can be easily spot cleaned. Purecare pillow protectors are treated with Antimicrobial Silver Product Protection to inhibit bacteria, mold, and mildew that cause deterioration, stains, and odors.
