What is hard water?

Hard water is probably the most common water problem found in the home. Hard water can leave spots on your glasses and dishes, make laundry dingy, dull or feeling scratchy, and cause soap scum and scale to build up around showers and faucets, which makes cleaning a chore. Hard water also can build up, causing hard water stains and buildup inside your water appliances, including dishwashers, washing machines, traditional water heaters, and new tankless water heaters.

The most common treatment for hard water in homes is an ion exchange water softener. An ion exchange softener removes dissolved hard minerals from the water, and creates “soft” water.

What is soft water?

Soft water is water that contains few or no dissolved minerals, such as calcium, magnesium, iron and manganese.

Water softening involves a process called "ion exchange" to remove the dissolved minerals that can't be trapped by a standard filter. Softeners use fresh resin beads with sodium ions attached to the resin. As water enters the tank, dissolved calcium and magnesium are attracted to the resin. The resin “exchanges” the sodium for the dissolved chemicals and the water is then rid of these impurities. What is filtered water?

Water filtration is water that has gone through filters to reduce the amount of iron, hydrogen sulfide, aesthetic chlorine taste and odor as well as microorganisms, such as cryptosporidium and giardia.

Water filtration involves separating mineral particles, like particulates, iron, hydrogen sulfide or organic matter, from the water molecule (H2O). By passing water through a "filter bed," or "media bed," these granular particles are trapped – allowing the clean water to pass through.

What are point-of-entry (POE) and point-of-use (POU) filtration products?

Point-of-entry (POE) water filtration products are systems that treat all of the water used in a home or single building. Culligan offers a wide range of whole house water filters that deliver cleaner water to every tap and water appliance in the house.

Point-of-use (POU) water filtration products are systems designed to treat only the water coming from the tap or water appliances to which it is connected. Culligan has a number of point-of-use drinking water systems, such as reverse osmosis systems, faucet filters, plumbed-in single tap solutions including shower filters, drinking water coolers, and drinking water filtration. These can often serve more than one purpose, most commonly filtering water for a drinking water tap in the kitchen, plus an icemaker or refrigerator line.

What is reverse osmosis (RO) technology?

Reverse osmosis (RO) is a filtration process where water molecules are forced through a semi-permeable membrane under intense pressure. The semi-permeable membrane only allows water molecules to pass through, treating the water by reducing specified contaminants3 such as arsenic V, barium, chromium and radium 226/228 and microorganisms, such as cryptosporidium and giardia.

Reverse osmosis water filter is a technologically advanced process that provides one of the most effective ways to filter water.

Reverse osmosis filtration technology is available in the Culligan Aqua-Cleer® system and point-of-use water coolers. We can recommend a reverse osmosis filtration system for you.

What are the benefits of a water softener?

A water softener removes the harsh minerals commonly found in hard water, leaving you with softer, mineral-free water that is much easier and gentler on everything that uses water.

Soft water is also better for your appliances and plumbing.
