Including filter system and high-performance Diquat filter.
Diquat is a herbicide used for vegetation control that can sometimes make its way into water supplies through runoff or operational use. Because it’s typically present at low levels and has no distinctive taste or odor, you usually won’t know it’s there without testing. Laird homeowners concerned about everyday exposure — in showers, cooking, and drinking — often choose to treat water where it enters the house so the whole household benefits from reduced levels at every tap.
Contaminant levels can change from one street to the next, so a single solution won’t always fit every Laird property. Water that looks clear can still carry dissolved chemicals, and seasonal runoff can alter what reaches source waters. A simple first step is to check any available water quality reports and, if you remain worried, get an independent test. From there, selecting a whole-house system tailored to your home will let you target contaminants like diquat without changing how you use your water.
To lower diquat in household water, the most effective single-filter choice is a high-quality activated carbon system. Carbon removes many organic chemicals by adsorption as water flows through, and in a whole-house configuration it also cuts nuisance chemicals that affect taste and odor. For Laird homes, the important factor is sizing the carbon tank and flow rate correctly so there’s enough contact time during showers, laundry, and when multiple taps run — something Mr. Pure Water can design for your house rather than relying on small cartridge solutions.
Not all carbon filters perform the same, so design choices matter when reducing diquat is the goal. A backwashing tank filled with catalytic or high-activity carbon helps keep the media working by preventing channeling and flushing out sediment that can block adsorption sites. This single-tank approach treats all incoming water in your Laird home, protecting fixtures and reducing what you might ingest, inhale as steam, or absorb on your skin. Adding prefiltration where needed can also improve carbon performance and extend time between services.
