Excalibur Signature UV Optimum 8 GPM Whole Home UV System – Colour Touchscreen
Complete UV Water Disinfection System for Smaller Homes & Cottages
The Signature Series Optimum 8 by Excalibur Water Systems is a compact, rack-mounted ultraviolet disinfection system built for point-of-entry installation on your home's main water line. With an 8 GPM flow rate and integrated pre-filtration, it provides whole-home protection against bacteria, viruses, and protozoan cysts — chemical-free.
Who It's For
The Optimum 8 is the ideal choice for smaller homes, cottages, and seasonal properties on well water or any source where microbial contamination is a concern. At 8 GPM, it's perfectly sized for households with 1–2 bathrooms and typical daily water demand.
What It Does
UV disinfection exposes water to ultraviolet light at 254nm, destroying the DNA of microorganisms and rendering them unable to reproduce. The Optimum 8 delivers 99.9999% (6-log) destruction of bacteria, viruses, and protozoan cysts — including E. coli, Giardia, and Cryptosporidium — with no chemicals, no taste impact, and no harmful byproducts.
