TOP 7 Different Types of Replacement Filter Cartridges : What They are and Their Characteristics.


Filtration is a vital process allowing us access to pure and germ-free water in the above-ground pool. Additionally, it gets rid of decontamination chemicals used in the purification process at treatment plants, ensuring we drink water that tastes amazing, minus any odd smells.

But to maintain top-notch water quality, switching your purification cartridges as required is paramount. Replacement cartridges for water filter are what you need for continued protection against harmful pollutants and water-borne illnesses.

This article focuses on the different types of cartridges that facilitate safe hydration.

Let’s delve into the specifics.

Types of water filter cartridges

The various types of cartridge water filters you can purchase include:

  • Carbon Filter

Using a carbon water filter cartridge as a decontamination medium helps you get rid of lead, chlorine, VOC’s, and hydrogen sulfide. Since its carbon is tightly packed, it offers hyper filtration capabilities where extra tiny particles do not pass through.

However, a downside to using this cartridge is it does not get rid of salts and sediment Also, due to the carbon’s compact nature, you can expect slower flow rates.

  • Reverse Osmosis Membranes

Ro cartridge filters are one of the most comprehensive systems that ensure safe hydration. These house water filter replacement cartridges feature multiple treatment stages, allowing them to remove almost all pollutants including sediment, gases, pesticides, chemicals, heavy metals, you name it!

However, as efficient as they are, they do not eliminate 100% of bacteria. Also, since it backwashes the pollutants out the drain, you will experience quite some water wastage.

  • KDF Filter Cartridges

When a KDF filter cartridge contacts impurities, an electron exchange process occurs, turning the pollutants into non harmful elements. This drinking water filter cartridge removes bacteria, hydrogen sulfide, heavy metals, pesticides and chlorine.

However, even with the effective elimination of an array of pollutants, coupling it with other treatment cartridges ensures full spectrum protection.

  • Granular Activated Carbon Filters

An activated carbon cartridge filter is similar to the block carbon cartridge only that the former is loosely packed, ensuring a faster flow rate.

Otherwise, they can undertake all tasks their block counterpart can, including successfully get rid of chloramines, harmful gases, chemicals, bacteria, and  VOCs.

  • Ceramic Filter

This is one of the most popular replacement cartridges for water filter. It has tiny pores that effectively get rid of harmful impurities such as bacteria, VOCs, and sediment.

Taking a closer look inside the ceramic filter cartridge, you realize it has a silver lining. This lining releases positively charged ions that eliminate heavy metals and kill bacteria instantly. However, they do not remove minerals, viruses, or TDS.

  • Alkaline Ionizer Filter

An alkaline ionizer water filter leverages the power of electrolysis to neutralize acidic elements in water and raise its PH levels, providing families with alkaline water. Alkaline water boasts numerous perks including ensuring oxygen easily flows throughout the body, cleansing the colon, weight loss, and cancer resistance. The cartridge also adds essential minerals to water, making sure we hydrate safely and healthily.

  • Sediment filter

These cartridges trap debris such as sand, tiny stones, branches, clay, and other insoluble particles. Since their capabilities do not extend past eliminating suspended materials, they cannot effectively remove bacteria or dissolved pollutants. For this reason, you must use it in conjunction with other purification mediums to achieve excellent decontamination.

Various sediment filter types are available for purchase. They include pleated, melt-blown, string-wound, spin-down, and bag filters. The difference between them is their purification mechanism and filtration efficiency.
