Indoor air quality has become a significant concern in recent years, especially as we spend more time indoors. Air purifiers have emerged as popular solutions for improving indoor air by removing pollutants, allergens, and other harmful particles. Among the various types of air purifiers available, ionic air purifiers have garnered attention due to their unique technology and filterless operation. However, despite their appealing features, ionic air purifiers are often ineffective and can even pose health risks. This comprehensive guide will delve into the functioning of ionic air purifiers, the associated dangers, and why air purifiers with replaceable filters are a better choice for ensuring clean and safe indoor air.Ionic air purifiers, also known as ionizers or ionizing air purifiers, function by emitting negative ions into the air. These negative ions attach to airborne particles, causing them to become heavier and settle onto surfaces or be captured by an electrostatic precipitator within the device.
