The Csonka Original Smoker Cloaker™ solves the #1 problem with smoking today. Individuals who use it consider it to be an amazing product definitely needed for both smokers and for non-smokers. The Csonka Smoker Cloaker, far superior to all basic ionizers that only promise to clean air with "negative ions", safely produces ozone (with the same fresh, clean smell you notice after an electrical storm) to completely cleanse the air. Every home, office, kitchen, bar, and restroom should have one! It works extremely well in very large rooms or offices (500 to 1,500 sq. ft.+), in your car, van or mobile home, and comes supplied with both a 12 v. DC and a 110 v. AC UL listed power cord. The Csonka Smoker Cloaker is virtually silent, uses no chemical components, is 100% maintenance-free, and requires no filters to change, ever! Finally, incredible as it is, it's contemporary mini-dome design is only 4" wide!
