Frequently Asked Questions

1. Does the UST-P55 remove bacteria and viruses?

Yes. The UST-P55 uses ultraviolet (UV-C) light to inactivate bacteria, viruses, and other harmful microorganisms, helping prevent them from reproducing and causing waterborne illness.

2. Does a UV water purifier remove sediment or chlorine?

No. A UV system disinfects microorganisms but does not remove sediment, chlorine, iron, or dissolved minerals. For best performance, it should be installed after appropriate prefiltration to ensure the water is clear enough for effective UV treatment.

3. Is the UST-P55 suitable for well water?

Yes. The UST-P55 is specifically designed for private well water and other untreated water sources where microbiological contamination may be a concern. It is commonly installed as the final stage of a complete whole-house water treatment system.

4. Does the UV lamp add chemicals or change the taste of water?

No. UV purification uses ultraviolet light to disinfect water without adding chemicals or affecting its natural taste, odour, or mineral content.
