The IONShield is an air purifying device with a built-in carbon brush system that releases negative ions into the air, which remove the nasty particles in your breathing range. It releases 60 million negative ions into the air per pulse, which guarantees clean air for you to breathe in. All of that fits into a small and stylish design, and it also has a 9 hour stand – by time, giving you freedom to stay outside all day and be safe from life’s nasties. Have friends that smoke? The IONShield takes care of second hand smoke too. It also improves your bodily function, and prevents bad odour! The choice is obvious. Protect yourself & and your family today!
