Set of cartridges for RO7 reverse osmosis systems with ionizer and SUPREME 100 GPD membrane. Complete package for multi-stage filtration: mechanical cartridges 5 µm and 1 µm, carbon cartridges, mineralizer, and bioceramic ionizer. Improves the taste and quality of water, supports membrane protection, and fits most 7-stage RO systems.
The RO7 cartridge set for reverse osmosis systems is a complete service package for 7-stage water treatment installations, equipped with a SUPREME 100 GPD osmotic membrane and an AIFIR ionizer. This water filter combines mechanical and carbon filtration, mineralization, and ionization, helping the water filtration system operate effectively, improving water taste, and protecting key system components. It is a practical choice for most RO7 installations where comprehensive maintenance, easy replacement, and stable reverse osmosis filter performance matter.

The RO7 Reverse Osmosis Cartridge Set AIFIR Membrane 100 GPD Water Filters has been prepared for 7-stage reverse osmosis systems. It includes a full set of cartridges needed for regular operation of an installation where not only pre-filtration stages are important, but also final taste improvement, mineralization, and an additional ionization stage.
This solution is for users who want to maintain high filtration efficiency, take care of the condition of the osmotic membrane, and preserve proper water quality in everyday use. The set fits 99% of 7-stage RO systems available on the market, making it a universal service kit for popular home installations.
The set includes all key elements needed to service a 7-stage reverse osmosis system:
The first stages of the set are responsible for retaining mechanical sediment and reducing contaminants that affect the taste, smell, and safety of further filtration. Polypropylene cartridges capture sand, silt, and suspended solids, while carbon elements help reduce chlorine and selected organic compounds.
Proper pre-filtration is crucial for membrane protection. Thanks to this, the SUPREME 100 GPD osmotic membrane can operate more efficiently, and the entire reverse osmosis system maintains high performance for longer.
After the osmosis stage, water passes through the WML2 mineralizing cartridge, which enriches it with essential minerals, and then through the ICB2-100 bioceramic ionizer. This configuration supports improved usability of the water and extends the classic RO system with an additional final treatment stage.
The set is designed for 7-stage RO systems, i.e. installations that use reverse osmosis to treat drinking water. It works well as a replacement set in home devices where an osmotic filter with additional water-quality improvement stages after the membrane is used.
It is the right choice for people looking for a complete service kit for a reverse osmosis filter device and wanting to replace all basic cartridges at the same time without sourcing the components separately.
Optimal operation: regular replacement of cartridges every 12 months and proper care of the SUPREME membrane significantly extend its service life and filtration efficiency.
In RO systems, proper operation directly affects water purification efficiency and the durability of the entire system. Worn pre-filters can limit membrane protection, which in turn leads to reduced filtration efficiency.
By replacing the set according to the recommended schedule, it is easier to maintain stable operation of the water filtration system, proper water taste, and suitable conditions for the osmotic membrane and final elements such as the mineralizer or ionizer.
| Filtration accuracy | 1 µm |
|---|---|
| Cartridge dimensions | height 10″ (25.4 cm) × diameter 2½″ (6.35 cm) |
| Cartridge replacement | every 12 months |
| RO membrane replacement | every 3–5 years (depending on water quality) |
| Operating temperature range | 2–42 °C |
The set fits 99% of 7-stage RO systems available on the market. It is intended for reverse osmosis installations using standard 10″ cartridges and additional final stages such as mineralization and ionization.
The set includes: a 5 µm polypropylene cartridge, a block carbon cartridge, a 1 µm polypropylene cartridge, a WWL2 inline carbon cartridge, a WML2 mineralizing cartridge, an ICB2-100 bioceramic ionizer, and a SUPREME 100 GPD osmotic membrane.
The cartridges should be replaced every 12 months. The RO membrane should be replaced every 3–5 years, depending on water quality and the system's operating conditions.
The SUPREME 100 GPD membrane is the main element of reverse osmosis filtration. It is responsible for the core water purification stage and offers a capacity of up to 100 gallons per day.
The WML2 mineralizing cartridge enriches the water with essential minerals. It is the final stage that improves the usability of the water after it has passed through the osmotic filter.
The ICB2-100 is a modern bioceramic filter for RO systems, manufactured by VFG Group in Germany. It uses specialized sintered clays fired at high temperature, strongly emitting FIR rays for better well-being.
The 5 µm polypropylene cartridge retains sand, silt, and sediment. The block carbon cartridge is responsible for adsorbing chlorine, pesticides, and aromatic compounds, while the 1 µm polypropylene cartridge provides more precise filtration and additionally protects the next stages of the system.
The operating temperature range is 2–42 °C. Staying within this range helps maintain proper system operation.
