L-GAC-Q UST-M is a linear carbon insert with granulated activated carbon from coconut shell. It effectively improves the taste and smell of water and helps remove unwanted contaminants. A new type of endings has been used: external 1/4 inch plugs for quick connectors, without the need for additional sealing. Used in reverse osmosis systems and for water filtration before refrigerators with dispensers and ice makers.
L-GAC-Q UST-M is a linear carbon cartridge with a 1/4 inch quick-connect fitting, designed for effective filtration and improved water quality. This water filter uses granular activated carbon made from coconut shells, helping to remove unwanted contaminants, improve the taste and odor of water, and support the operation of systems such as reverse osmosis, an osmotic filter, or a reverse osmosis system. It works well both as a water treatment component in RO filters and upstream of refrigerators with a water dispenser and ice maker.

The L-GAC-Q UST-M linear carbon filter is filled with a high-quality bed of granular activated carbon made from coconut shells. This filtration material is valued for its very good adsorption properties, which is why the cartridge effectively supports everyday water filtration wherever fresh taste and a pleasant odor of utility water matter.
The cartridge helps reduce the presence of unwanted contaminants while improving the organoleptic properties of water. This solution is particularly useful in installations where water is used directly for drinking, preparing beverages, or supplying devices that require clean water with better taste.
The L-GAC-Q UST-M model is standardly installed in reverse osmosis systems. It can operate both in classic RO sets and in modern solutions where fast and convenient replacement of consumable components is important.
The cartridge is also used in water filtration systems installed before refrigerators equipped with a water dispenser and ice maker. Thanks to this, it works not only as a reverse osmosis filter, but also as a universal component improving water quality in household appliances.
The carbon grain size in this model has been selected so that water remains in contact with the media for longer. This operating method increases the effectiveness of contaminant adsorption and allows better use of the properties of active coconut carbon.
This is especially important wherever a water filter is intended not only to support water treatment, but also to genuinely improve its everyday usability. Longer water contact with the media translates into more efficient cartridge performance in drinking water installations.
The L-GAC-Q UST-M filter features a new type of connection used in modern osmotic filters. It uses external 1/4 inch plugs onto which installation fittings are pushed. This solution does not require additional sealing, which simplifies both installation and cartridge replacement.
Thanks to this, the cartridge fits well with the requirements of modern installations, where ease of servicing, connection tightness, and compatibility with popular solutions used in RO systems are important.
Important: the cartridge uses external 1/4 inch plugs for quick-connect fittings. Installation does not require additional sealing. Before selection, it is worth making sure that the connection diameter is compatible with your existing system.
Linear carbon filters, depending on the installation point, can perform different functions in the system.
This versatility means that the L-GAC-Q UST-M can be matched to various device configurations based on an osmotic membrane and other components responsible for precise water purification.
The replacement frequency depends on the cartridge installation point in the system and on the quality of the feed water.
Operating note: cartridge service life depends on the amount of water and the degree of contamination of the incoming water. In systems with a higher load or poorer water quality, more frequent inspection and earlier replacement may be necessary.

It is a linear carbon cartridge designed to improve water taste and odor and support the removal of unwanted contaminants. It is used in reverse osmosis systems and before refrigerators with a water dispenser and ice maker.
The cartridge is filled with granular activated carbon made from coconut shells. This is a filtration material with very good adsorption properties, commonly used in the treatment of drinking water.
Yes, this is a cartridge commonly used in reverse osmosis systems. It can serve as a pre-filter in built-in systems or as a final polishing filter in most typical RO installations.
The cartridge has a 1/4 inch connection in the form of external plugs for quick-connect fittings. This connection method does not require additional sealing.
The grain size has been selected so that water remains in contact with the media for longer. This increases the effectiveness of contaminant adsorption and improves the efficiency of the cartridge.
If the cartridge operates before the membrane in a built-in system, replacement is recommended after 3 months, but not less frequently than every six months. When it operates at the final stage of water treatment, it may be replaced not less frequently than once a year.
Service life depends on the amount of water used and the degree of contamination of the incoming water. The more demanding the operating conditions, the sooner the cartridge may require replacement.
Yes, the L-GAC-Q UST-M model is suitable for water filtration before refrigerators with a water dispenser and ice maker, where it helps improve the taste and odor of both water and ice.
The cartridge operates at a temperature of 2–40°C, with a maximum pressure of 6 bar and a maximum flow rate of 3.5 l/min. Its dimensions are 10" x 2".
