What is a whole home water filtration system?

A whole-home water filtration system filters water at the main point of entry, ensuring clean, filtered water throughout your entire home for drinking, cooking, bathing, and cleaning.

How does revers osmosis work?

Reverse osmosis pushes water through a semipermeable membrane that removes contaminants like chlorine, heavy metals, and other impurities, providing purified water for drinking and cooking.

How often should I replace the filters?

Whole-home systems are made to last 8–10 years; we typically replace the entire system at a discount vs. replacing media filters. RO drinking system filters need replacement every 12–18 months.

How hard is the water

San Diego water is classified as 'very hard', typically measuring between 15-29 grains per gallon (300-500 ppm). This is among the hardest water in California and causes significant scale buildup

What is the difference between a softener and a filter

A softener removes hard minerals (calcium/magnesium) that cause scale and dry skin. A filter removes contaminants like chlorine, chemicals, and sediment for better taste and safety. Many homes benefit from a combination system.
