Water filtration systems remove hundreds of contaminants including chlorine, lead, bacteria, PFAS, and hard water minerals that affect your family's health and home.

Summary:
Chemical contaminants represent some of the most concerning substances in your water supply. These invisible threats often have no taste or smell, making them particularly dangerous for Indianapolis families.
Chlorine tops the list of chemicals most homeowners want removed. While municipal water treatment facilities use chlorine to kill harmful bacteria, it leaves behind an unpleasant taste and smell. More concerning, chlorine can combine with other compounds in your water to create potentially harmful byproducts.
PFAS chemicals, often called “forever chemicals,” have become a major concern in Indiana water supplies. These man-made substances don’t break down naturally and can accumulate in your body over time, potentially causing serious health issues.
Activated carbon filtration stands as one of the most effective methods for removing chemical contaminants from your water. This technology works through a process called adsorption, where contaminants stick to the carbon’s surface as water passes through.
The carbon used in these systems comes from materials like coconut shells or wood that have been heated to create millions of tiny pores. These pores dramatically increase the surface area available for capturing contaminants. When chlorine molecules encounter the activated carbon, they get trapped in these pores and removed from your water supply.
What makes activated carbon particularly effective is its ability to remove not just chlorine, but also volatile organic compounds (VOCs), pesticides, and herbicides. For Indianapolis homeowners dealing with agricultural runoff, this technology can eliminate chemicals like atrazine, 2,4-D, and simazine that commonly contaminate our water sources.
However, not all carbon filters are created equal. Solid carbon block filters generally outperform granular activated carbon because they force water to take a slower, more thorough path through the filtration media. This increased contact time allows for better contaminant removal, though these filters may need more frequent replacement.
The effectiveness of carbon filtration depends heavily on proper maintenance. As the carbon becomes saturated with contaminants, its ability to remove additional chemicals decreases. Regular filter replacement ensures your system continues protecting your family from chemical contamination.
When you need the most comprehensive chemical removal possible, reverse osmosis systems deliver unmatched performance. These systems use a semi-permeable membrane that blocks contaminants while allowing pure water molecules to pass through.
Reverse osmosis excels at removing contaminants that other filtration methods struggle with. PFAS chemicals, which have become a growing concern in Indianapolis water supplies, are effectively reduced by properly designed RO systems. The membrane’s microscopic pores also capture heavy metals like lead, arsenic, and mercury that can leach from aging pipes.
The multi-stage process typically includes pre-filtration to remove larger particles, the reverse osmosis membrane for molecular-level filtration, and post-filtration to polish the water. This comprehensive approach removes up to 99% of dissolved contaminants, including nitrates, perchlorate, and hexavalent chromium.
One consideration with reverse osmosis is water waste. These systems require approximately three to five times more water input than they produce, with the excess water carrying away rejected contaminants. However, for families concerned about chemical contamination, this trade-off often proves worthwhile.
RO systems also remove beneficial minerals along with contaminants, which can affect water taste. Some manufacturers address this by offering mineral drops or remineralization filters to restore essential minerals after the purification process.

Physical contaminants include any solid particles suspended in your water supply. These range from visible sediment and rust to microscopic particles that can affect your water’s taste, appearance, and safety.
Indianapolis homeowners often notice physical contaminants more readily than chemical ones. Cloudy water, rust-colored stains, and particles in your glass all indicate physical contamination that filtration systems can address.
Sediment filtration typically serves as the first line of defense in comprehensive water treatment systems. These filters capture particles before they can damage more sensitive filtration components downstream.
Sediment filters work through physical straining, capturing particles larger than the filter’s pore size. These systems are particularly important for Indianapolis homes with well water or older municipal infrastructure that may contribute iron and rust particles.
The most common sediment filters use materials like spun polypropylene or pleated paper to trap particles. Filter ratings typically range from 50 microns down to 1 micron, with smaller numbers indicating finer filtration. A 5-micron filter removes particles visible to the naked eye, while 1-micron filters capture much smaller contaminants.
Iron presents a particular challenge for many Indianapolis-area homes. When iron-rich water contacts oxygen, it forms rust particles that can stain fixtures, laundry, and dishes. Sediment filters capture these rust particles, but addressing iron contamination often requires specialized treatment methods.
For homes with significant sediment issues, multi-stage filtration proves most effective. A coarse pre-filter removes larger particles, protecting finer filters downstream. This approach extends filter life and ensures consistent water quality throughout your home.
Regular maintenance is crucial for sediment filters. As particles accumulate, water flow decreases and filtration efficiency drops. Most sediment filters require replacement every 3-6 months, depending on your water quality and usage patterns.
Whole house water filtration systems address physical contaminants at your home’s main water line, ensuring every tap delivers clean water. These systems typically combine multiple filtration technologies to handle the full spectrum of contaminants found in Indianapolis water.
The first stage usually involves sediment filtration to remove particles and protect downstream components. Next, activated carbon filtration addresses chemical contaminants like chlorine and VOCs. Some systems include additional specialized media for specific local concerns, such as iron removal or pH adjustment.
Whole house systems offer several advantages over point-of-use filters. They protect your entire plumbing system and water-using appliances from sediment damage. Your water heater, washing machine, and dishwasher all benefit from cleaner water, potentially extending their lifespan and improving efficiency.
For Indianapolis homeowners dealing with hard water, whole house systems often include water softening or conditioning components. These address the calcium and magnesium minerals that cause scale buildup, soap scum, and appliance damage throughout your home.
The key to effective whole house filtration lies in proper system sizing and component selection. Your water’s specific contaminant profile determines which filtration media and technologies will be most effective. Professional water testing helps identify these needs and ensures your system addresses your home’s unique challenges.
Maintenance requirements vary by system complexity, but most whole house filters need attention every 6-12 months. Some systems feature automatic backwashing to extend filter life, while others require manual filter replacement. Regular maintenance ensures consistent performance and protects your investment in clean water.
Understanding what contaminants water filtration systems remove helps you make an informed decision about protecting your family’s health and home. From chlorine and PFAS chemicals to sediment and hard water minerals, modern filtration technology can address virtually any water quality concern.
The most effective approach starts with professional water testing to identify your specific contaminant profile. Indianapolis water varies significantly depending on your source and location, making this assessment crucial for selecting the right filtration technology.
Whether you need a simple under-sink filter for drinking water or a comprehensive whole house system, the key is matching your filtration technology to your water’s unique challenges. We specialize in custom water treatment solutions designed specifically for Indianapolis-area water conditions, ensuring your family enjoys clean, safe water from every tap.
