To ensure a UV purifier continues to protect bathers against pathogens like viruses, bacteria, and molds, it is imperative to replace a UV lamp early. But what’s the lifespan of a UV lamp? And how do you know it’s time to order a dealer to sell UVC lamps (จำหน่ายหลอด UVC, which is the term in Thai) to you?
The average lifespan of a UV lamp is 9,000 hours, while amalgam lamp has a greater lifespan of roughly 13,000 hours. The lamp will still keep working after this period, but the disinfecting value will steadily decrease from then on. Hence, it is imperative to replace the UV lamp early to ensure the bathers’ health.
Note: 9,000 hours is approximately one year. Hence it is advisable to replace a UV lamp once a year.
