Aquasana FAQs
1. Do I need a plumber to replace the UV filter?
Our replacement filters are designed for DIY replacements – no plumber is required. Please read through the owner's manual carefully before attempting to replace your filters. If you have any questions or need assistance, our technical support representatives at 866-662-6885 can walk you through the installation process.
The UV Filter Replacement Lamp should be replaced every 12 months.
If you purchased your Max flow system between July 2019 and April 2026, you will use this AQ-UV-L420C Replacement Lamp. Otherwise, you will use the AQ-UV-510L UV Replacement Lamp.
This UV filter lamp is independently tested to sterilize up to 99.99% of bacteria and viruses and 99% of cysts for peace of mind. UV filtration is more effective and more eco-friendly than chemical disinfection processes at sterilizing these contaminants.
Because bacteria and viruses are more prevalent in homes that use well water, our Rhino® Well Water with UV comes standard with an ultraviolet filter specifically designed to render bacteria and viruses inactive. The UV Filter safely sterilizes up to 99.8% of bacteria and nonpathogenic viruses. For homes using city water, we offer the UV Filter as an add-on to our whole house filters that provide supplemental bactericidal treatment.
UV filters are extremely economical to operate. A typical 10 gallon per minute (gpm) UV filter operates on the same power requirements as a 40-watt light bulb.
No, UV is a physical disinfection process. It does not change the taste or odor of the water. It simply provides safe, reliable disinfection while adding nothing to your water.
No, the UV filter should be left on whether you are using water or not. The lamp ages regardless of the amount of water drawn through the system. By leaving the unit on, you will eliminate the potential problem of having bacteria and viruses pass through the filter while the unit is off. However, if water is drained from your disinfection system, your UV filter must be switched off.
UV lamps have a powerful life of approximately 9,000 hours, which means that the lamps require annual replacement. The UV light may offer illumination beyond 1 year; however, there will not be enough UV energy to provide adequate disinfection. Proper maintenance of any pre-treatment is also required. Additionally, the sleeve must be cleaned at least once a year.
Yes, our UV filter is designed for water that has already been filtered through a home filtration system and not as a standalone unit. For UV filters to be effective, it is recommended that the influent water contain the following:
  • Iron < 0.3 ppm (0.3 mg/L)
  • Manganese < 0.05 ppm (0.05 mg/L)
  • Hardness < 7gpg
  • Tannins < 0.1 ppm (0.1 mg/L)
  • Turbidity < 1NTU
  • UV transmittance > 75%
