If you want to protect your household's water supply from waterborne microbes, consider installing a UV water sterilization system. This technology provides a comprehensive solution for treating your water by using UV light to inactivate microbes, ensuring safe water throughout your entire home.
Here are some of the top UV systems we recommend.
The Viqua VH410 is a popular residential UV water filter system. With flow rates at 18 gpm, the VH410 produces enough water for homes with 4-7 bathrooms and features a lamp end-of-life timer which counts down the days until the UV lamp should be replaced.
NOTE: If no other filters or pretreatment are installed before the UV system, we recommend the Viqua VH410-F20.
This whole-house UV water treatment system is an "integrated UV system," meaning it incorporates powerful UV water treatment WITH a pre-filter. The prefilters are designed to remove chemicals, metals, sediment, and improve the taste and odor of your water.
The VIQUA Arros 15-IHS22 is a whole-home water filtration system that uses ultraviolet (UV) light to inactivate microbes such as cryptosporidium, giardia, E. coli, legionella, norovirus, and hepatitis A virus † in your water supply.
Applications for this system include homes on municipal city water, well water or those that treat collected rainwater. With flow rates at 12 gallons per minute, this system easily provides enough filtered water for the entire home.
The compact Viqua VH410-F20 UV system offers a compact, easy to install option for those seeking a high-quality whole home UV system that is backed by a solid warranty.
With a capacity of 18 GPM, this "point of entry" UV treatment unit is ideal for homes with up to seven bathrooms. The VH410-F20 is a comprehensive home water filtration system that employs ultraviolet (UV) technology to inactivate waterborne microbes in a water source.
Expert Tip to Select the Right Size UV System
For whole-home applications, a simple way to determine what size UV system is needed, is by assessing the number of bathrooms in the house. Here's a flowrate guide for whole-home UV sterilizers.
1 Bathroom: 6 gallons per minute flow rate
2 Bathrooms: 9 gallons per minute flow rate
3 Bathrooms: 12 gallons per minute flow rate
4 Bathrooms: 15 gallons per minute flow rate
5 Bathrooms: 18 gallons per minute flow rate
Flow rates for commercial applications are determined with a variety of other factors. Please contact us for more information.
FAQs
Are whole house water purifiers worth it?
Does UV light really sanitize water?
Yes, ultraviolet light (UV) is a proven method for sanitizing water. When water passes through a UV disinfection system, the UV light disrupts the DNA or RNA of microorganisms, such as bacteria, viruses, and protozoa. This prevents them from reproducing and effectively renders them harmless. UV disinfection is considered environmentally friendly as it does not require harsh chemicals. However, it's crucial to maintain the UV system properly, ensuring the light intensity is sufficient and the water is clear of any turbidity or sediment that might shield microorganisms from the UV rays. Learn more about UV water sterilizers work.
How does a whole-house UV water disinfection system work?
A whole-house UV water disinfection system uses ultraviolet light to neutralize harmful microorganisms in your water. The UV lamp emits germicidal UV-C rays that penetrate bacteria, viruses, and protozoa, destroying their DNA so they can’t reproduce or cause illness. This process provides chemical-free, safe water purification for your entire home.
What contaminants does a UV water treatment system remove?
UV water treatment systems effectively inactivate bacteria, viruses, and parasites such as Giardia and Cryptosporidium. However, UV light does not remove sediment, chlorine, or dissolved metals, so pairing your UV system with proper pre-filtration ensures complete water purification and better overall water quality.
How do I choose the best UV water disinfection system for my home?
Choosing the best UV water disinfection system depends on your home’s water flow rate, water clarity, and source quality. Look for a system that matches your gallons-per-minute (GPM) demand, offers high UV intensity, and includes durable components like a quartz sleeve and quality ballast. For optimal protection, select a system certified for your specific water conditions.
What maintenance does a UV water disinfection system require?
Regular maintenance ensures your UV system runs efficiently. Replace the UV lamp annually, clean or replace the quartz sleeve when it becomes cloudy, and inspect O-rings and seals. Keep the system powered on continuously and maintain good pre-filtration to prevent sediment buildup and extend the lifespan of your UV components.
What is the life of UV lamp in water purifier?
Generally, UV lamps need to be replaced every 12 months. Their lifespan is roughly 9,000 hours, which translates to around 375 days of continuous operation before a bulb change is necessary.
Are UV water disinfection systems safe and environmentally friendly?
Yes, UV water disinfection systems are one of the safest and most eco-friendly ways to purify water. They use ultraviolet light—no chemicals, chlorine, or byproducts—to neutralize bacteria, viruses, and protozoa. This process doesn’t change water taste or odor and leaves no harmful residues. It’s a sustainable, low-maintenance solution ideal for homeowners seeking reliable and chemical-free water purification.
