My second Ionbox arrived today. I purchased the first about a month ago and have been moving it from room to room. I expect to buy a third soon, and possibly a fourth. Every year I worry that I won’t be able to stand the second-hand smoke in my house when the windows are closed through the winter. It’s gotten harder for me every year. Now, it’s a pleasure to breathe the fresh, cleansed air. The Ionbox has saved either my health or my marriage, I guess both. So glad I tried it! I strongly recommend the Ionbox“.
