How does an under-sink water filtration system work?

Is it possible to have both an under-sink water filtration system and a water softener?

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.

Are under-sink water filters environmentally friendly?

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.
