Including filter system and high-performance 1,4-Dichlorobenzene filter.
1,4-Dichlorobenzene is a synthetic chemical that can sometimes appear in drinking water and become a concern if concentrations are high. Also called p-Dichlorobenzene, many people recognize it by a sharp, mothball-like odor rather than the chemical name. Because it can affect a home's water smell and perceived quality, Noma homeowners often choose to treat water where it enters the house. A whole-house system reduces exposure during daily uses like showering, laundry, and dishwashing so the issue is addressed throughout the home.
This chemical has been used in products such as moth repellents and deodorants and can reach drinking water through industrial handling, disposal, or contaminated runoff and groundwater. It can persist in the environment because it does not break down quickly under normal conditions. Even if water looks clear in Noma sinks, an unpleasant odor may become noticeable in hot showers or when several taps are running. If you suspect a problem, testing your water will confirm whether 1,4-Dichlorobenzene (p-Dichlorobenzene) is present and help determine the appropriate treatment.
To reduce 1,4-Dichlorobenzene in household water, a single whole-house granular activated carbon (GAC) filter is commonly the best option. Activated carbon adsorbs many organic contaminants, including p-Dichlorobenzene, as water flows through the carbon media. Because a GAC unit treats all incoming water, it improves water quality at kitchen taps, showers, and appliances across Noma homes—important for contaminants that are noticed by odor during bathing and cleaning.
A correctly sized whole-house carbon tank is built to handle a home's flow rates so filtration keeps pace with daily use. Media depth and contact time, plus scheduled media replacement, are key to sustained reduction of 1,4-Dichlorobenzene over time. Mr. Pure Water can help Noma residents choose a GAC system based on your water test and household needs, then install it at the main line so all water entering your home is filtered for simpler, whole-home protection.
