Whole Home Water Filtration

South Bay Water Filters specializes in whole home water filtration systems. We exclusively sell HALO filtration products – their most popular system being the HALO 5.

With over 40 years of experience in water filtration, HALO sets the highest bar for maintenance-free, trouble-free operation.

As a plumbing business with 35 years of experience installing various systems, we have found the HALO 5 to be the most simple, reliable and effective solution for removing contaminants from your household water.

We are a family-owned business serving the South Bay and Peninsula and have made it our mission to educate our friends and neighbors and community at large on the dangers lurking in our tapwater. The Bay Area’s many water districts simply can’t filter out all the contaminants. That’s where the HALO 5 comes in. 



How it works

HALO has been the leading innovator in water filtration for over 40 years. Here’s how they do it.

Granular Activated Carbon (GAC)

Premium grade acid-washed GAC for the general removal of chlorine, chloramines, gases, dyes, fuels, heavy metals, man-made pollutants, disinfectants, pesticides, TTHM, sodium hypochlorite, undesirable odors, undesirable taste and volatile organic contaminants.

High Activity Carbon (HAC)

HAC is an outstanding material for successfully reducing free chlorine from water supplies. The end product is clean, fresh water with no objectionable taste or odor characteristics. Additionally, HAC can be used for filtering waters having a wide range of pH levels and will impart a high “polish” to the filtered water.

Filter-AG Plus®

HALO Ag Plus is an all-natural, environmentally safe media with a large surface area and microporous structure. It is a highly efficient filter media for the reduction of suspended matter down to the 5 micron or less range and is thus, extremely effective at removing water turbidity.

High Density Garnet Filter Media

Garnet is a high hardness, high density granular filtration media that can effectively filter down to the 10-20 micron range. It also provides an excellent support bed for the other filtration media.

HALO ION Inline Water Conditioner

Our proprietary HALO ION 2.0 In-line Water Conditioner uses multi-reversing polarity permanent magnetic fields to alter the molecular structure of positively and negatively charged ions of dissolved calcium and magnesium. This causes the hard water minerals that would normally cause limescale to stay suspended in the water instead of attacking pipes and appliances. The conditioned water also helps prevent corrosion due to scale and will dissolve existing scale over time.
