I’ve been a maniac with air pollution for ages. I have an air cleaner device and air purifying bags basically in every room of my house. I use an air ozone generator at my office, and I had different devices in our two cars. I decided to buy my first Airbubbl last December and I immediately noted the difference. It is much more effective, and it covers my driver seat and the two rows of passenger seats (a big SUV!). I just bought my second Airbubbl for my wife’s car.
