It’s raining outside, the window is open. Don’t close the window and start the air conditioner. Leave the window open and let the breeze blow! Water won’t get in with your new Waterproof Air-Permeable Mesh Privacy Screens (WAMPS). Made of a new screen mesh, they don’t let any of the rain in while allowing air to circulate freely. The screen mesh also turns transparent to opaque if you want privacy, but also want to keep natural air flowing into the room. You can now sleep with the window open regardless of the weather, saving the cost and environmental impact of running the air conditioner.
