Including filter system and high-performance Nitrate filter.
Nitrate can enter a household water supply when it moves through soil into groundwater or surface sources, and it usually has no taste or smell — so water that looks fine may still contain it. Many Lois homeowners first find out about nitrate from a water test or a supplier notice about source conditions. If you want reliable protection at every tap, treating water where it enters your Lois house is the most straightforward option.
Because nitrate remains dissolved, it won’t settle out and standard carbon filters don’t remove it effectively. That can be disappointing for families in Lois who already filter for chlorine or sulfur but still need nitrate-specific treatment. Nitrate and nitrite are discussed together at times, yet dissolved ions like nitrate need targeted systems. The first practical step is testing your Lois water so you know whether nitrate is present and which treatment approach will work best.
For whole-house nitrate reduction, a whole-house reverse osmosis system is the most effective single-filter choice. RO uses a semi-permeable membrane to reduce dissolved contaminants like nitrate instead of only addressing taste and odor. When installed at the main water entry to a Lois home, it treats water for showers, laundry, kitchens, and bathrooms, giving consistent reduction at every faucet rather than only at one sink.
A correctly designed whole-house reverse osmosis installation includes prefiltration and the controls the membrane needs to stay effective over time. Prefilters protect the RO membrane from sediment and chlorine, while the membrane itself does the nitrate reduction. Because whole-house RO produces some wastewater and usually requires storage and delivery components, proper sizing and installation for your Lois home are important — Mr. Pure Water can help choose the right configuration for your water and usage.
