Filtering systems

Our water filters remove solids from water and reduce scale build-up. We also have a range of specialized water filter systems that fight stains and improve the quality of your drinking water. At the heart of your Culligan filtration system is the filter cartridge. The cartridge is the barrier between you and the contaminants that make your water smell or taste funny. Culligan cartridges capture the tiny, unseen particles floating in your water (some as small as an atom) so what comes out is refreshing, clean, and purified Culligan drinking water. A water filter means better water in you house or business.

We offer a wide range of filters for a myriad of water problem-solving challenges. Three commonly used types of filters that improve water for a range of uses are:

  • Mixed-Media Depth—with a longer filtration time, these filters eliminate more solids from water.
  • Granular-Activated—while removing chlorine and organic materials from your water, the Cullar activated carbon in these filters stands up to the abrasioncommon in this kind of filter.
  • Cullsorb—two-layer filtration give these filters optimum efficiency. A top layer of anthracite takes care of minerals, a second bed of manganese greensand removes smaller particles and chemicals.

Please contact us so that we may help you determine the type of filtering system that may be best suited to your needs. For a more complete list of our available filtering systems, see other products.

Drinking Water Filters

You can get delicious water for an economical price with the Culligan’s Drinking Water Filters. Using state-of-the-art, two-step activated carbon filtration, this filter removes chlorine taste and smell (and other objectionable tastes and odors) from your drinking water. It also removes particles as small as 5 microns which can cloud water. The result is better tasting, clear water for drinking, cooking and making coffee, tea and juices. Compact and easy to install, the filter fits conveniently under your kitchen sink. For added convenience, filter cartridges are easily replaced in just minutes.

We also have countertop drinking water filters, faucet filters and single tap filters for your drinking water needs. The ultimate drinking filter is the reverse osmosis system.

Whole House Filters

With the Culligan whole house filters, you can be sure you’re getting one of the most dependable, convenient, advanced filters on the market today. These will fit in any home or business, whether you’re on a private well or a public water system. Filters are tough on iron water and prevents rust stains on your clothes, fixtures, and dishes. They stop that “rotten egg” odor from hydrogen sulfide. Hydrogen sulfide leaves black stains on your laundry and bathroom fixtures. Even worse, it can cause serious damage to your pipes, leading to costly plumbing repairs. We also have sediment water filters.

And because this design allows for a steady stream of filtered air and water, you don’t get “glugging.”

Although water intake varies from family to family, a standard amount of bottled water for a household of four will typically range from two to six 5-gallon bottles of delivered water. Depending upon your level of activity, this monthly amount could be as high as twelve 5-gallon bottles.
