🧾 Overview

The Culligan WSH-C125 is a showerhead water filter with a chrome design. This filter has a lifespan of 10,000 gallons, roughly equating to 6 months, to help you get maximum use out of the unit before paying for a replacement cartridge. The filter itself reduces chlorine and sulfur odor, as well as scale caused by hard water minerals like calcium and magnesium. It has 5 spray settings, including full-body spray and pulse.

Everything you need for installation of the Culligan shower head is included, even teflon tape and a handy cartridge reminder sticker that you can use to measure when it’s time to buy a new filter. The filter can be installed on a ½-inch threaded shower arm, and can be used with a temperature range of 40 to 120 degrees Fahrenheit. If certification is important to you, you’ll be reassured to know that the Culligan shower head filter is tested and certified to ANSI standard 177, and it also meets the EPA WaterSense standard of minimum of 1.8 gallons or less.

🚦 Performance

The biggest plus point of the Culligan shower head performance-wise is that it’s certified to do exactly what the manufacturer claims. It has a certification to NSF/ANSI standard 177 for chlorine reduction, and it also meets the EP WaterSense certification standard of a minimum 1.8 gallons per minute or less. This means that not only can you be certain that this filter will remove chlorine from your water, it also won’t affect your water pressure to the point of being inefficient.

The Culligan WSH-C125 lasts for up to 10,000 gallons of water, or 6 months, which is on the higher end of filter lifespans. Of course, this is only a generalization, as if your water is very hard or contains a higher level of contaminants, you will probably clog the filter up faster, which means you’ll need to replace it more frequently. But this is still a good lifespan compared to many drinking water filters.

🔧 Installation & Maintenance

The Culligan shower head water filter cartridge comes inside its own showerhead, so you will need to remove your current showerhead and replace it with this one to benefit from water filtration. This is slightly limiting, as the Culligan WSH-C125 only comes in one color and style, so you don’t get much say when it comes to appearance. Still, installation is simple, and the unit comes with everything you’ll need to attach it straight onto your shower arm.

Providing your shower arm is a standard 1/2-inch threaded, the WSH-C125 should fit perfectly without the need for an adaptor. You just screw the showerhead in place, using the provided teflon tape to prevent leaking, and the job is done. You don’t even need to fit the filter, as it comes pre-installed in the system. Just make sure to run the system through with water for 10 minutes to flush out any loose filter media.
