Our under-sink systems are designed for quick, do-it-yourself installation and connect directly to your existing cold-water line — no drilling, no extra faucet required. Simply mount the unit under your sink, attach it in-line with your current cold-water hose, and tighten the fittings. Turn the water back on, check for leaks, and flush the system briefly. Most customers complete the entire setup in just a few minutes.

As water flows through the filtration layers, contaminants like chlorine, lead, and sediment are trapped and reduced. Our Carbon Block model uses high-performance activated carbon to improve taste and remove common impurities, while our Ultrafiltration option adds an ultra-fine membrane for even greater contaminant reduction to deliver cleaner, better-tasting water.

Your Cura Water Filtration System includes a 1-year limited warranty covering defects in materials or workmanship (excluding filter cartridges). For more details, view our full policy or contact us with proof of purchase.

Our Carbon Block filter lasts 9–12 months, while the UF filter lasts 12–18 months and can handle up to 14,000 gallons of water. Lifespan may vary based on water quality and household use.

Replacing your filter is quick and easy. Simply pull and twist to release the old filter. The process is designed to be leak-proof and takes just 3 seconds.

We offer a 60-day risk-free return policy on all full-priced Cura Water Filtration Systems. For more details, view our full policy
