Including filter system and high-performance Toluene filter.
Toluene is a volatile organic compound (VOC) that can enter drinking water when fuels, solvents, or industrial chemicals reach a source. Because it can dissolve in water and also evaporate into the air, you might notice more than just a change in taste — some homeowners report a gasoline-like or chemical smell coming from hot water, showers, or water that’s been sitting in pipes. In Noma, the only way to know for sure whether toluene is present in your household supply is to have the water tested, since odors aren’t a reliable indicator on their own.
Many Noma homeowners choose to treat toluene where the water enters the house so every faucet, shower and appliance receives the same protection. A whole-house approach can also reduce the chance of VOC odors releasing during normal activities like bathing, laundry or heating water. For added peace of mind it’s common to pair a whole-house system with a point-of-use drinking water treatment if you want extra reassurance for the kitchen tap.
For reducing toluene, a single, whole-house activated carbon filter is the most effective straightforward option. Activated carbon removes solvent-type contaminants by adsorbing organic molecules onto its large internal surface as water flows through the media. This method is widely used for VOCs such as toluene and can also help improve taste and odor — but it must be correctly sized with adequate contact time to achieve meaningful reduction.
A whole-house activated carbon system treats water before it reaches bathrooms, the kitchen and the laundry, helping deliver more consistent water quality across your Noma home. Performance depends on factors like flow rate, the specific carbon used, and your household’s water use, so choose a system matched to your needs and local conditions. Regular maintenance — especially replacing the carbon media on schedule — keeps the system working, and follow-up testing can confirm that toluene levels are being reduced as expected.
