The Science Behind The Clean
The HALO 5 uses a multi-stage approach to reduce contaminants and condition water — all without salt or ongoing maintenance.
Catalytic carbon reduces chlorine, chloramines, heavy metals, pesticides, and VOCs. Meets NSF/ANSI drinking water standards.
Secondary carbon filtration improves taste and odor across a wide pH range, suitable for all water sources.
Natural, eco-safe media with a microporous structure reduces turbidity and filters particles down to 5 microns.
High-density garnet captures finer particles (10—20 microns) and stabilizes other filter media for peak efficiency.
Multi-reversing magnetic fields transform calcium and magnesium into harmless crystals, preventing scale without salt.
Our Products
Both systems are maintenance-free and backed by a IO-year warranty. We’ll help you find the right fit for your home’s water needs.
5-Stage Whole-Home Filtration & Conditioning

Got Questions?
Everything you need to know about whole house water filtration and our installation services here in the South Bay.
A pitcher or fridge filter only treats the water you drink. Everything else in your home, your shower, your bath, your washing machine, your dishwasher, still runs on unfiltered water. Whole house filtration treats every drop that enters your home, so your skin, your laundry, and your appliances all benefit, not just your drinking glass.
Many of our customers install a whole house system specifically because of dry skin, itchy scalp, or eczema flare ups they believe are related to chlorine and hard water. Removing chlorine and reducing hard minerals often makes a noticeable difference in how skin and hair feel, especially for kids with sensitive skin.
Most homes in our service area deal with some combination of chlorine, hard water minerals, and sediment. Chlorine is added to municipal water for treatment, but it’s also what causes that noticeable taste and smell and can dry out skin and hair. Hard water minerals leave spots on dishes and glassware and build up inside pipes, water heaters, and appliances over time.
A water softener is designed to address hard water minerals, often using salt. Whole house filtration is designed to remove chlorine, sediment, and other contaminants throughout your home. During your consultation, we’ll walk you through your specific water conditions and recommend whichever approach, or combination, fits your home.
Most installations are completed in a single visit by one of our licensed technicians, typically within a few hours depending on your home’s plumbing. We treat your home with care throughout, and we’ll walk you through everything before we start so there are no surprises.
Our systems are designed to be low maintenance. There’s no scrubbing filters or remembering to add anything on a schedule. We’ll explain exactly what, if anything, is needed for your specific system during your consultation, and we’re always a phone call away if questions come up later.
We install whole house water filtration systems for homeowners throughout the South Bay, including Los Altos, Los Altos Hills, Palo Alto, Saratoga, Los Gatos, Cupertino, Mountain View, Sunnyvale, Campbell, and San Jose.
