Carbon & Sediment Filter Cartridges


One of the most effective cartridges used for filtering contaminants out of your water supply are carbon water filters. Carbon filter cartridges use activated carbon to effectively absorb chlorine, chloramine, VOCs, pesticides, and other common chemicals used in municipal water, while removing unpleasant tastes and odors from the water. Certain carbon filters are also designed to remove additional contaminants including sediment, lead, and cysts. There are different methods of carbon filtration, however there are three main types of filters:

  • Granulated activated carbon (GAC)
  • Carbon block filters
  • Radial flow GAC filters

Carbon water filters are often used as stand-alone water filtration solutions for improving the taste, clarity, and purity of potable water sources. They are also used as pre-treatment for reverse osmosis systems to remove the chlorine and chemicals from the water to protect the RO membrane from damage. The experts at wateranywhere are available to assist you and answer any questions you may have to guarantee the best solution for your needs.

Applied Membranes, Inc. RO Replacement Sediment Filter Cartridges


At wateranywhere, we offer the essential parts and accessories for your water treatment equipment and home RO system to provide the most effective method of water purification. Our selection of replacement sediment filters are used in pre-filtration in RO and UV disinfection treatments. Sediment filters are effective in removing suspended particles and turbidity from water, reducing the look of cloudiness and preventing sediment scale and buildup from entering your water supply. Sediment filters are recommended for food and beverage preparation, industrial and commercial processes, and for residential whole-house filtration. There are two main types of replacement sediment filters:

  • Depth filters-captures progressively smaller particles as water flows through them and are categorized as melt-blown or string-wound.
  • Surface filters-designed to tram larger sediment.

Things to consider when choosing a replacement sediment filter are length, diameter, flow capacity, and micron rating.

In-Line Filters & Cartridges


We carry a variety of competitively priced in-line sediment filters. In-line filters are ideal for both residential and commercial applications, and the design of these filters eliminate the need for additional filter housings and offer extended filtration life. These types of RO replacement filters are ideal for whole-house reverse osmosis filtration with a variety of filter types from ceramic to carbon GAC filters to fit your specific needs.
