I got one years ago to check out microwaves and how far back you should stand then gave it away. Maybe filter windows too but after a bad quake wasn’t a fan of putting things like beds by window and use thick double curtains with the out side light see through for the day. That would help in blasts for risks of being impaled by glass too. It saved my daughter when she was a baby when a child ran to house with a crazy druggie boyfriend was after her 6 yr old child all bruised and while mother was in the hospital and child was running for his life. I grabbed a butcher knife he ran but then he threw a big rock through window. Luckily the curtain stopped flying glass from cutting up the baby. That’s southern California for ya. Don’t live there no mas lol
I guess they got a new trick friend said. A fake blast to get people to the windows then the real blast.
Its worse than you think with the graphene. Now they want to make nanobots out of it. These fools are contaminating everything with it. Even the ocean.
