- 3/4" connections suitable for many household installations,
- includes 2 BL10 USTM carbon cartridges,
- improves the taste and smell of water,
- helps reduce chlorine and selected organic compounds,
- transparent housing for easy assessment of cartridge dirt buildup,
- double sealing system with 2 O-rings,
- air vent supporting proper operation of the housing,
- possibility of single or series installation,
- key, seals and mounting plate included.

Versatile application
The filter has been designed for broad use in homes and apartments. It can operate as a standalone filter housing or as part of a larger water treatment system.
- Ideal for installation on the pipe supplying cold water to an apartment or before expensive household appliances.
- Works with a wide range of mechanical, specialty and carbon cartridges available on the market.
- The set includes 2 BL10 USTM carbon cartridges.
As a result, the filter can serve both as practical protection for the installation and as an element that improves the comfort of everyday water use.
Operation of the BL10 USTM carbon cartridge
The set includes two carbon block cartridges with activated carbon. This filter cartridge combines mechanical action with adsorption properties, which is why it is widely used in domestic filtration systems.
- Mechanical filtration: the carbon block acts as a mechanical filter, trapping larger contaminants such as sand, rust, deposits and other solid particles.
- Adsorption: the main advantage of the carbon block is its ability to adsorb chemical substances from water. Activated carbon has a large internal surface area, which allows it to effectively bind organic compounds, chlorine, pesticides, industrial contaminants and other chemical substances.
- Improved water smell and taste: thanks to activated carbon's ability to remove volatile organic contaminants, the carbon block cartridge can improve the smell and taste of water by removing unpleasant odours and aftertastes.
- Chlorine removal: activated carbon is a very effective chlorine absorbent, which is why carbon block cartridges are often used in water filtration systems to remove chlorine from drinking water, resulting in a more pleasant taste and smell of water.

Applications of the carbon cartridge
- Drinking water filters: carbon block cartridges are often used in drinking water filtration systems to improve the taste, smell and quality of drinking water. They can be used in under-sink water filtration systems in home kitchens to provide purified water for cooking and drinking.
- Whole-house or apartment filters: removing chemical and organic contaminants from water using activated carbon filters helps protect the plumbing system from contaminant buildup and premature wear of devices such as boilers, dishwashers or washing machines.
Durable and refined design
The filter uses a two-piece 10" in-line housing from WodaRO®, providing reliable protection for your water system. The design has been developed with convenient use, tightness and easier cartridge condition monitoring in mind.
- It consists of a transparent housing and a head with a 3/4" brass thread.
- The durable, high-quality housing guarantees safe and stable use.
- The transparent housing makes it easy to assess the level of cartridge contamination.
Double sealing system and air vent
The tightness of the system and stable operation of the housing are crucial in flow filtration. That is why the filter has been equipped with solutions that improve safety and ease of use.
- Equipped with two sealing O-rings, ensuring maximum tightness of the product.
- The gasket also helps maintain pressure inside the in-line housing, preventing air from entering the system.
- The air vent allows pressure inside the housing to equalize with atmospheric pressure, eliminating the risk of damage to filtering or sealing elements.
- Thanks to the air vent, water filters and in-line housings can operate more efficiently, regardless of operating conditions and pressure in the water system, which translates into improved water quality and longer service life of the devices.

Flexible installation and convenient operation
The filter can be used as a single filtration stage or as part of a more extensive system. This solution gives great freedom in adapting the installation to the needs of a particular house or apartment.
- It can be installed individually or connected in series, providing flexible adaptation to the user's needs.
- The set includes everything you need for quick and correct installation, including the in-line housing, sealing O-rings, a key and a mounting plate.
The filter is intended for cold water installations. The transparent housing makes it easy to monitor cartridge wear on an ongoing basis, and regular cartridge replacement helps maintain filtration efficiency, flow performance and proper operation of the entire housing.
