Water Treatment Consumables & Replacment Filters
Maintaining the performance and efficiency of your water treatment systems requires the right consumables. We supply a comprehensive range of high-quality consumable products designed to keep your systems running smoothly and effectively. From filter cartridges to RO membranes and filtration media, we have everything you need for your home.
Understanding Water Filtration Media
Filter media play a crucial role in water treatment by trapping impurities and improving water quality. Charcoal, known for its adsorption properties, effectively removes chlorine, odors, and organic compounds. Gravel serves as a support layer, promoting even distribution of water flow and preventing channeling in filtration systems. Sand acts as a coarse filter, capturing larger particles and sediment to enhance water clarity. Its uniform size distribution ensures efficient filtration. Together, these media create a multilayered filtration bed, each contributing to the removal of specific contaminants and the production of clean, safe drinking water.
Water Treatment Consumables
Filter Cartridges
Filter cartridges are essential components of water filtration systems, responsible for removing contaminants and impurities from your water supply. At Blue Steel Water, we offer a variety of filter cartridges designed to meet your specific filtration needs. Whether you require sediment filters, carbon block filters, or specialty cartridges for targeted contaminant removal, we have options to suit every application.
Different Types of Filters
Our selection of filters encompasses a wide range of technologies and configurations to address various water treatment challenges. From particulate filters that capture sediment and debris to activated carbon filters that adsorb chlorine, odors, and organic compounds, we have filters to improve the taste, odor, and clarity of your water. Additionally, we offer specialty filters for specific contaminants like lead, arsenic, and fluoride, providing tailored solutions for enhanced water quality.
RO Membranes
Reverse osmosis (RO) membranes play a critical role in RO water purification systems, effectively removing dissolved solids, contaminants, and impurities from your water. Our RO membranes are engineered for optimal performance and durability, ensuring reliable filtration and producing high-quality drinking water. Whether you need replacement membranes for residential, commercial, or industrial RO systems, we have options to meet your requirements.
Filtration Media Consumables
In addition to filter cartridges and RO membranes, we offer a range of filtration media consumables to support your water treatment systems. This includes salt for water softeners, which helps regenerate the ion exchange resin and maintain water softness. We also provide activated carbon for adsorption-based filtration, as well as specialty media for iron and manganese removal, pH adjustment, and other water treatment applications.

Water Filter Cartridges

PP Cartridge (Sediment Filter)
-
Material/Design: Spun or wound polypropylene
-
What it Removes: Sand, dirt, rust, and large particles
-
Main Use: First stage filtration to protect other filters
Zimbabwean borehole water often contains sand and rust particles that can damage appliances and clog finer filters. The PP cartridge acts as the first line of defence, trapping visible dirt and protecting the rest of the filtration system.

Granular Activated Carbon (GAC) Cartridge
- Material/Design: Loose activated carbon granules
-
What it Removes: Chlorine, taste, odour, organic compounds
-
Main Use: Improves water taste and smell
Municipal water supplies in Harare, Bulawayo, and other towns often have high chlorine levels. The GAC filter helps reduce chlorine, making water taste fresher and removing chemical smells.

Carbon Block Cartridge (CTO)
-
Material/Design: Compressed activated carbon block
-
What it Removes: Chlorine, taste, odour, some chemicals
-
Main Use: Deeper purification and health protection
This cartridge provides strong chlorine removal, reduces chemical residues, and ensures your water is safe for cooking and drinking. For many Zimbabwean homes using borehole water treated with chlorine, the CTO filter is essential.

Ultra Filter Cartridge (UF)
-
Material/Design: Hollow-fibre membrane (0.01 micron)
-
What it Removes: Bacteria, viruses, fine particles
-
Main Use: Microbiological safety while keeping natural minerals
Borehole and well water in rural Zimbabwe may contain bacteria and viruses. The UF cartridge acts as a microbiological barrier, giving families peace of mind that their water is free from harmful pathogens, while still keeping beneficial minerals.

Post Carbon Block Cartridge (T33 / Polishing Filter)
-
Material/Design: Activated carbon (often coconut shell)
-
What it Removes: Residual tastes and odours
-
Main Use: Final polishing stage before drinking
This final stage ensures your water tastes fresh, clean, and pleasant—ideal for households that want bottled-water quality straight from their tap.
