How Often Should You Replace a UV Light?

Most lamp manufacturers, such as Phillips, GE, and Sylvania, recommend replacing the UV lamp every 9000 hours or approximately every 12 months. This is to ensure that the lamp continues to emit at least 80% of its original UV-C emission. An annual replacement program is also recommended for those with allergies and other respiratory conditions. The frequency of changing a UV light depends on several factors, such as how often the system is used and how it is used. Generally, a UV germicidal light used to disinfect indoor air must be replaced every 9000 hours, which is equivalent to 12 months.

If you or your family members suffer from allergies or asthma, it is essential to adhere to a regularly scheduled UV bulb change plan. UV lights can also prevent airborne biological contaminants from circulating through the indoor air of your home by preventing mold and bacteria from accumulating in the humid components of the air conditioning. If your UV lamp is three years old, turn off the system until the UV bulb is replaced. We offer a variety of services for your air conditioning system, whether you need to install a new UV lamp or want to learn more about the benefits of UV lamps. If you can't replace the UV light after two years, turn it off or unplug the power supply until you change it. Like a regular bulb, UV lights have a limited lifespan, so they need to be changed regularly.

For most UV disinfection systems, complying with an annual replacement program will ensure that ultraviolet lights continue to keep indoor air in the house healthy. New automated systems emit UV light depending on the use of heating, ventilation and air conditioning systems.

However, like any air purification product or service, UV lights are not invincible to damage or last forever. Therefore, it is essential to follow a regular schedule for changing your UV bulbs in order to keep your home's air healthy and safe.
