Trusted Arsenic Under Sink Water Filter Systems

Yes. Reverse osmosis systems are commonly used to remove or significantly reduce arsenic in drinking water when properly selected, installed, and maintained. Aqua General offers the AquaGuard® Undersink 9-Stage Reverse Osmosis Filter, which is designed to remove or reduce arsenic along with lead, chlorine, organic chemicals, pharmaceuticals, and other contaminants.

For drinking water, reverse osmosis is one of the most effective point-of-use treatment methods for arsenic reduction. The best approach starts with water testing, because arsenic form, concentration, and overall water chemistry influence treatment performance. Aqua General provides free on-site water analysis, then recommends an undersink RO system or supporting treatment based on the results.

Arsenic can be reduced by specialized filtration media and reverse osmosis membranes, depending on whether the arsenic is present as arsenic III or arsenic V. Aqua General’s AquaGuard® 9-stage RO system uses multiple treatment stages, including advanced carbon filtration and membrane separation, to address arsenic and many other drinking water contaminants.

Aqua General’s AquaGuard® Undersink 9-Stage Reverse Osmosis Filter is a 50-gallon-per-day system installed under the sink and connected to a dedicated drinking water faucet. It uses multiple filtration stages to reduce contaminants, improve taste and odor, and then adds beneficial minerals back through the Bio-Sure filter stage.

Installation requirements vary by sink layout, cabinet space, and plumbing condition, but most undersink reverse osmosis systems are designed for a clean, compact installation beneath the kitchen sink. Aqua General’s technicians evaluate the site, connect the system properly, install the drinking water faucet, and confirm the system is operating correctly before completion.

Routine maintenance is essential for reliable arsenic reduction and good water quality. Reverse osmosis systems typically need periodic filter changes, membrane checks, sanitizing, and performance testing. Aqua General services and repairs many RO brands and keeps a comprehensive inventory of replacement parts for routine service, media replacement, and long-term maintenance.

Yes. Aqua General offers complimentary water analysis to help identify water quality concerns before recommending a treatment system. Testing helps determine whether an undersink RO system is appropriate and whether other contaminants, hardness, chlorine, chloramine, metals, or dissolved solids should be considered in the final treatment recommendation.
