Culligan residential water filters :

Eliminate minerals responsible for color, odors, iron, organics, arsenic, nitrites and nitrates, PFAS, and much more.

Culligan® water filters

Culligan’s unique water filters consist of advanced, patented systems that filter problem-causing minerals such as color, sediment, manganese, iron, chlorine and even gases such as hydrogen sulfide (sulfur), and PFAS from your water.

The filters capture these particles (as small as 10 microns), while the water circulates through them. Periodically, the filter needs to be backwashed, so the unit automatically shuts down. The flow of water through the filter is reversed, and the impurities that have been captured are rinsed away and directed to the drain. Once this is complete, the filter is ready to go back to work.
