How It Works
Three stages
- 1
Sediment pre-filtration
Water enters through the spin-down sediment prefilter, removing sand, silt, and large particles before they reach the main filters.
- 2
Carbon filtration
The CTO carbon block stages remove chlorine, chemicals, odors, and common tap water impurities including VOCs and taste-affecting compounds.
- 3
UV sterilization
UV sterilization eliminates 99.99% of bacteria and viruses before water reaches your taps.

UV sterilizer
iSpring UVF50 LED ultraviolet sterilization system — mercury-free, no warm-up, and nothing to replace: no bulb, no quartz sleeve. The LED module is long-life, and its indicator light turns RED when it is no longer working properly, so you know without a service call. When it does fail you replace the unit, not a part. Needs a 120V outlet at the unit.

Why This System?
Perfect for homeowners who want reliable, basic whole-house protection. The sediment + dual CTO carbon block removes chlorine, sediment, and odors — the most common complaints in Rosarito's water supply. This is our most affordable whole-house system, giving you cleaner water from every tap. It does not reduce lead or heavy metals — for that, see our Best WGB32B-KS.
Every system includes a 30-day satisfaction guarantee and is eligible for our BWS Care plans — scheduled filter changes, UV lamp replacement, and full system inspections.

How Often Should I Replace My Filters?
We recommend a visual inspection every 6 months and a full filter replacement every 12 months. Local water is hard on filters, so keeping to this schedule holds the system at full performance and protects everything downstream. UV bulbs also lose intensity over time and should be replaced once a year. With a Whole House Care Plan we track when yours are due, bring the right iSpring set, and install it on schedule. The annual filter set, UV bulb, and two service visits per year are all included, so there is no border run to source parts and no guessing when they are due.
