Frequently asked questions

Culligan under-sink water filtration systems use either activated carbon or reverse osmosis membranes to remove impurities and contaminants from your tap water. As water passes through these filters, they trap and reduce common pollutants, providing cleaner, better-tasting water directly from your tap.

These systems can effectively remove a wide range of contaminants, including chlorine, sediment, heavy metals (like lead and copper), bacteria, viruses, pesticides, and various chemicals. The specific contaminants removed depend on the type of filter used in your system. Get in touch with our experts to learn more.

The frequency of replacing bottles on your bottled water cooler depends on factors such as your water consumption rate, the size of the bottles, and the number of people using the cooler in your home. Typical households of 4 people might need to replace bottles every 1 to 2 weeks.
With Culligan water delivery our rental plans factor in your usage and automatically schedule deliveries based on your needs.

Professional installation is recommended to ensure proper placement, leak-free connections, and optimal performance. A professional installer can also help you choose the best location for your system. Culligan engineers have years of experience installing a wide range of water systems for homes.

Absolutely. These two systems serve distinct purposes within your home. While under-sink water filtration systems enhance the quality of your drinking water, water softeners effectively combat hard water issues like limescale buildup, water spots on dishes, and dry skin. This dual setup allows you to address all aspects of your water quality, ensuring optimal results for cleaning, bathing, cooking, and drinking water.

If you're searching for ways to have a more eco-conscious home, under-sink water filtration offers an excellent starting point. By providing a virtually endless supply of filtered water at home, this approach reduces the reliance on disposable plastic water bottles. Thanks to Culligan water solutions, it's estimated that 40 billion plastic bottles are saved from ending up in global landfills each year.
