Air purifier bulbs are a type of accessory that are used in certain types of air purifiers that use ultraviolet (UV) light technology to kill airborne bacteria, viruses, and other microorganisms. These bulbs emit a specific wavelength of UV-C light, which is germicidal and can destroy the DNA of microorganisms, rendering them unable to reproduce and spread. Air purifier bulbs typically need to be replaced every 6-12 months, depending on the manufacturer's recommendations. This is because the effectiveness of the UV-C light diminishes over time, and the bulb may eventually burn out. It is important to replace the bulb on schedule to ensure that the air purifier continues to function effectively.
When choosing air purifier bulbs, it is important to select a bulb that is compatible with your air purifier model. It is also important to choose a high-quality bulb from a reputable manufacturer, as lower-quality bulbs may not emit enough UV-C light to be effective.
