Can an air purifier be repaired if the UV bulb stops working?

Yes, most UV air purifiers can be repaired by replacing the failed UV bulb. The usual cause is a lamp reaching end of life; less often, a ballast, power issue, or a safety interlock keeps the lamp from firing. A technician can test the circuit, match the exact lamp type, and replace the bulb or related parts; if the assembly or electronics are badly degraded, replacement may be the smarter long-term choice.
