Drinking Water FAQs
What contaminants does a drinking water system remove?
Culligan drinking water systems can remove a wide range of contaminants including chlorine, lead, arsenic, nitrates, bacteria, viruses, and many other dissolved solids. The specific contaminants removed depend on the type of system you choose.
What is reverse osmosis and how does it work?
Reverse osmosis (RO) is a filtration process that forces water through a semi-permeable membrane. This membrane has tiny pores that allow water molecules to pass through while blocking larger contaminant molecules, resulting in purified drinking water.
How often do I need to replace the filters?
Filter replacement frequency depends on your water quality and usage. Typically, pre-filters should be changed every 6-12 months, while the RO membrane can last 2-3 years. Your Culligan dealer can help you establish a maintenance schedule based on your specific needs.
Is bottled water better than filtered tap water?
Not necessarily. Home filtration systems like reverse osmosis often provide water quality equal to or better than bottled water, at a fraction of the cost. Plus, you avoid the environmental impact of plastic bottles and the inconvenience of purchasing and storing them.
What’s the difference between whole-home and point-of-use systems?
Whole-home systems filter water at the point it enters your home, providing filtered water to every faucet. Point-of-use systems, like under-sink RO units, filter water at a specific location. Many homeowners use both for comprehensive water treatment.
Does filtered water taste different?
Yes, most people notice a significant improvement in taste. Filtered water removes chlorine and other chemicals that cause unpleasant tastes and odors. Many customers describe the water as crisp, clean, and refreshing.
Can I rent a drinking water system?
Yes, Culligan offers flexible rental options for drinking water systems. Rental includes installation, maintenance, and filter replacements in one convenient monthly payment. It’s a great option for those who want hassle-free service without a large upfront investment.
How do I know which drinking water system is right for me?
The best way to determine the right system is to schedule a free water test with your local Culligan dealer. They’ll analyze your water quality and recommend solutions tailored to your specific water concerns, household size, and budget.
