Including filter system and high-performance Nitrate filter.
Nitrate can enter a household water supply after moving through soil into groundwater or surface sources, and it usually has no taste or smell—so water can seem fine while containing dissolved nitrate. Many Franjo homeowners only discover it through testing or public notices about source water. If you want assurance at every tap in your home, treating the water where it enters the house is the most reliable way to address possible nitrate.
Because nitrate stays dissolved, it won’t settle out like sediment and ordinary carbon filters can’t remove it effectively. That can be frustrating for families in Franjo who already use filters for chlorine or odor but still need nitrate-specific reduction. Nitrate (often discussed alongside nitrite) requires treatment designed for dissolved ions, so begin with a water test to see whether nitrate is present and which removal method matches your home’s needs.
For whole-home nitrate reduction, a whole-house reverse osmosis system is the single-filter option that removes dissolved contaminants like nitrate. An RO membrane reduces ions rather than simply improving taste, and when installed at the main water line it treats water used for showers, laundry, kitchen fixtures and bathrooms—helpful for Franjo households that want consistent protection at every tap instead of only at one sink.
A properly designed whole-house reverse osmosis system for a Franjo home includes prefiltration and the controls the membrane needs to perform reliably. Prefilters protect the RO membrane from sediment and chlorine, while the membrane does the nitrate reduction; because RO generates some wastewater and normally pairs with storage and delivery components, correct sizing and installation are important.
