FAQs
What contaminants do under-sink water filters in Duff remove?
Our multi-stage under-sink systems are designed to target the most common water issues in Duff, including chlorine, sediment, rust, heavy metals (lead, mercury), volatile organic compounds (VOCs), pesticides, herbicides, and unpleasant tastes or odors. Optional stages such as reverse osmosis or remineralization cartridges can also reduce dissolved salts, fluoride, nitrates, and pharmaceuticals.
How often do I need to change the filter cartridges?
Most sediment and carbon block cartridges last 6–12 months, while reverse osmosis membranes typically last 2–3 years. Actual lifespan depends on your household’s water quality and usage. Each system ships with a maintenance schedule sticker, and color-coded cartridges make DIY replacement simple. A noticeable drop in flow rate or return of chlorine taste are common signs it’s time to replace a cartridge.
Will the system reduce my water pressure at the kitchen tap?
The dedicated filtered-water faucet delivers about 1.0–1.5 gallons per minute—fast enough to fill a pot or bottle quickly. The system is plumbed in parallel with your regular cold-water line, so there is no impact on pressure at your main kitchen faucet, dishwasher, or refrigerator.
Can I install the under-sink filter myself, or do I need a plumber?
Most homeowners with basic DIY skills can complete the installation in 45–90 minutes using household tools. The kit includes push-fit connectors that clip onto your existing ½-inch supply line, a drilling template for the faucet, and a clear step-by-step guide. If you are uncomfortable drilling through quartz, granite, or cast-iron sinks, or if local regulations require a licensed installer, we recommend hiring a Duff-licensed plumber.
How much space does the system take up inside the cabinet?
A standard 3-stage system measures roughly 14" H × 12" W × 4" D, leaving plenty of room for cleaning supplies. Reverse-osmosis units include a two-gallon storage tank (9" D × 14" H). Before ordering, open your cabinet, locate the cold-water shut-off valve, and measure clearance to be sure you can mount the bracket and still close the doors comfortably.
Is the filtered water certified safe to drink?
Yes. Our filter media are NSF/ANSI 42 and 53 certified for aesthetic and health-related contaminant reduction. Reverse-osmosis systems carry additional NSF/ANSI 58 certification. All wetted components meet NSF/ANSI 61 for material safety, and the final assemblies are pressure-tested to 125 psi before leaving the factory.
