- The WiFi cover is constructed from a unique blend of Copper, Nickel, and Polyester Fiber, certified to provide 99.999% electromagnetic protection. This high-quality fabric ensures excellent conductivity and shielding performance. - Designed with dual openings, you can easily adjust the level of blocking strength by choosing to open or close the sides. For enhanced blocking, simply tie the two open sides together for a complete enclosure. - This cover fits most WiFi routers, regardless of whether they have antennas. Its lightweight design allows for easy portability, making it suitable for use in various settings, including homes, offices, and hotels. - Our EMF-blocking WiFi cover is made from breathable fabric that promotes natural airflow to keep your router cool. For optimal protection, wrap the cover around the entire modem/router when not in use. For everyday use, we recommend covering just the router antennas while using WiFi, and enclosing the entire unit during sleeping hours or when away from home. - Please note that the cover is not machine washable, ensuring durability over time without compromising its protective qualities. - Practical scenarios for use include: 1. Shielding your router while you sleep to reduce EMF exposure. 2. Taking the cover on trips to protect against electromagnetic radiation in unfamiliar environments. 3. Using the cover in shared spaces, such as offices, to minimize potential health risks from prolonged WiFi exposure.
