The ERWIN M. LUSINI Pura zipper is a specialized pillow protector cover measuring 40x40 cm, designed to maintain a hygienic sleeping environment. Its construction features a polyurethane top side and a polyester bottom, creating a breathable yet liquid-impermeable barrier that keeps the pillow dry and clean. This cover is particularly helpful for allergy sufferers, as it is engineered to be proof against mites, bacteria, viruses, pollutants, and bed bugs. To ensure long-term safety and cleanliness, the white cover is flame retardant according to BS 7175 Crib 5 standards and carries the OEKO-TEX® STANDARD 100 certification. It is built for rigorous maintenance, allowing for disinfection with commercial products and machine washing at 95 °C, though you should avoid chlorine or bleach. For drying, a gentle tumble dry or dry-cleaning is recommended to preserve the integrity of the zipper closure and the protective materials.
