Including filter system and high-performance Aluminum filter.
Aluminum is a metal that occurs in nature and can enter household water for a few reasons. It may dissolve into source water as it moves through soils and rock, or appear after certain treatment steps that use aluminum-based coagulants to clarify water. While trace amounts are common, many Cox homeowners choose to test and address higher concentrations so they know exactly what’s coming from their taps. If you’re worried about aluminum in your home’s water, a certified water test is the first step to understanding your situation.
Because aluminum won’t always change the smell or taste of water, it can go unnoticed without laboratory testing. Sometimes it shows up as reduced clarity or sediment when the water’s chemistry shifts, but even clear water can contain dissolved metals. Homeowners in Cox often prefer a preventative measure that protects drinking, cooking, bathing, and laundry water across the whole house rather than just at a single faucet.
For whole-house reduction of aluminum, a properly sized reverse osmosis system installed at the point of entry is usually the most effective single-filter solution. RO systems push water through a semipermeable membrane that separates dissolved metals, including aluminum, from your water stream. Because aluminum can take different chemical forms depending on pH and other factors, membrane filtration delivers reliable removal across a variety of water conditions; prefiltration is included to protect the membrane and maintain consistent flow.
A whole-house reverse osmosis installation is built as a treatment train even though the membrane does the bulk of the removal. Sediment and activated carbon stages are typically placed before the membrane to reduce fouling and improve taste and clarity, and post-treatment options can help condition water for everyday use. Mr. Pure Water can assess Cox homes, recommend the right system capacity based on your water test, and advise on maintenance intervals so aluminum is reduced before it reaches fixtures and appliances.
