DESC: This special bonus pack combines the home air purification power of the original Ionic Pro CA500 with the new Ionic Pro CAC1 Car Ionizer at one special price. The Ionic Pro CA500 ionic air purifier traps irritants and allergens on three collection blades and then releases purified air back into the room. Works in spaces up to 500 square feet. At the same time, enjoy similar air purification in your car with bonus Ionic Pro CAC1 Car Ionizer. Just plug the Ionic Pro Car Ionizer into your car's cigarette lighter/accessory power socket and sit back and enjoy the ride as it works silently and effectively to clean, refresh and purify the air.
