How Often Should Your UV Air Purifier’s Bulbs Be Changed?

A UV air purifier can be an excellent addition to your home’s air filtration system. They work by causing cellular damage to, and effectively killing, particles such as mold, mildew, viruses and bacteria within your ductwork. The cool, dark environment of your ducts provide the perfect breeding ground for these microorganisms, but a UV air purifier can kill them before they have the chance to grow and get circulated through your indoor air.

Just like any air purification product or service though, UV lights are not invincible to damage, nor do they last forever. While the system itself may not ever need preplacement, changing the UV lamp is essential to ensuring the effectiveness of the system.

How Often Should You Change the Lightbulbs?

This is going to depend on a few factors, such as how you use the system and how often you use the system. Generally speaking, a UV germicidal light that’s being used to disinfect your indoor air needs to be replaced every 9000 hours. This equates to approximately 12 months. If you or your family members suffer from allergies or asthma, then keeping to a regularly scheduled UV lightbulb change plan is absolutely essential to your well-being.

It may seem wasteful to change a light before it “burns out.” However, after the first year UV lights begin to lose their germicidal effectiveness. If not changed on a regular basis, then the mold and mildew it was preventing may start to form inside your ductwork. If you wait too long to change the light, then you would need to have your ducts cleaned, as UV air purifiers cannot eliminate mold that is already present. Additionally, the excessive energy being used by an aging UV lamp could cause your power supply to overheat. With regular maintenance though, our HVAC professionals can check this as part of their full system inspection.
