DESC: The Csonka line of Smoker Cloaker ozone air purifiers are guaranteed to eliminate smoke odors. These are not smoke filters or simple ionizers. Instead the Csonka is an ozone purifier. It automatically produces ozone and will continuously purify the air. This means there is no maintenance ever - no chemical components, nothing to clean, no filters to change, no liquids to add, nothing. Just plug it in, turn it on, select a setting and you can let it run all year. It will also neutralize other airborne odors and contaminants, including pet dander, bacteria, mold spores and other impurities.
