Best Premium Whole Home UV System with Pre-Treatment
This whole-house UV water treatment system is an "integrated UV system," meaning it incorporates powerful UV water disinfection WITH a pre-filter. The prefilters are designed to remove chemicals, metals, sediment, and improve the taste and odor of your water.
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.
Best Small Home UV System
The compact Viqua VH200 offers an affordable option for those seeking a high-quality whole home UV system that is backed by a solid warranty.
With a capacity of 9 GPM, this "point of entry" UV disinfection unit is ideal for homes with up to three bathrooms. And the VH200 features a countdown timer that indicates when it's time to replace the UV lamp.
Expert Tip: Know How Much Water You Use
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
Are whole house water purifiers worth it?
Yes, UV water purifiers are very effective at removing 99.99% of microbiological contaminants including bacteria, fungi, protozoans, viruses, and cysts.
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.

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.
