UV light systems are one of the most effective ways to disinfect tank water, but to keep them working properly, regular bulb replacement is essential. These bulbs typically need changing every 12 months, even if they still appear to be glowing. That’s because the UV strength naturally fades over time, reducing its ability to neutralise bacteria and viruses.
This collection includes a wide range of UV replacement lamps and sleeves for leading water treatment systems. Whether you’re running a rural tank supply or just want that added layer of protection for your household water using water filter, we’ve got the right fit. Always double-check your system model before ordering, and if you're unsure, our team is happy to help.
Additional Information
When Should You Replace the Lamp of Your UV Light Water Filter?
Exposure to UV light at the correct wavelength is an incredibly effective disinfection method. It destroys bacteria by disrupting microorganism DNA, preventing them from reproducing or performing other vital life functions. UV light is perfect for use on food and liquids as it is a chemical-free disinfection method that does not leave behind any taste-altering by-products.
Bacteria or faecal coliforms can sometimes contaminate tank water without being noticed. Installing an effective UV light water filter produces UV-C rays, the wavelength of UV light that kills microorganisms, which is crucial for the effective sterilisation and purification of water. However, you may experience a drop in effectiveness if you use UV lamps beyond their rated total usage hours. Replace your UV water filter bulbs at least once a year or perform maintenance according to the manufacturer’s manual to ensure optimum disinfecting performance.
