Description
The 3/4" Whole House Flow Water Filter + Carbon Block Cartridge USTM is a robust water filter designed for installation at the cold water inlet to a house or apartment. This 10" in-line water filtration system helps improve water taste and odor, reduces chlorine and selected organic compounds, while also protecting plumbing and household appliances from contaminants. The set includes an filter cartridge USTM BL10, a mounting key, seals, and a mounting plate, making the kit ready for convenient installation and everyday use.

3/4" in-line filter for the home and household appliances
This is a reliable solution for people who want to improve water quality throughout the home or protect selected points of the installation. The filter can operate on the pipe supplying cold water to an apartment, house, or directly before household appliances particularly sensitive to scale and contaminants.
The model is based on a 10" in-line housing and has been designed to combine durable construction with convenient cartridge status monitoring. Thanks to the transparent sump, the user can continuously observe the degree of cartridge soiling without having to disassemble the housing.
Key benefits
- intended for cold water and installation at the main inlet or before household appliances,
- 3/4" connection suitable for many domestic installations,
- 10" housing standard and compatibility with many cartridges available on the market,
- included USTM BL10 carbon cartridge improving water taste and odor,
- reduction of chlorine and selected organic compounds,
- transparent sump for easy cartridge condition monitoring,
- double sealing system increasing tightness,
- air vent supporting proper housing operation,
- option for single installation or series connection.
Versatile application
- 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 a USTM BL10 carbon cartridge.
This arrangement means the filter can serve as a standalone water treatment stage or be part of a larger system. It works well wherever basic improvement of utility water quality and additional protection of the installation matter. In more advanced solutions, it can operate as part of a larger water preparation system, alongside technologies such as reverse osmosis or an under-sink filter, if the installation requires multiple purification stages.

Operation of the USTM BL10 carbon cartridge
The set includes a carbon block cartridge with activated carbon. This is a solution valued in domestic water treatment due to the combination of mechanical and adsorption action.
Cartridge operating range
Mechanical filtration: the carbon block acts as a mechanical filter, retaining larger contaminants such as sand, rust, sediment, 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 enables effective binding of organic compounds, chlorine, pesticides, industrial contaminants, and other chemical substances.

Improved water odor and taste: thanks to activated carbon's ability to remove volatile organic contaminants, the carbon block cartridge can improve water odor and taste by removing unpleasant smells and aftertastes.
Chlorine removal: activated carbon is a very effective chlorine adsorbent, which is why carbon block cartridges are often used in water filtration systems to remove chlorine from drinking water, resulting in a more pleasant water taste and odor.
Applications of the carbon cartridge
Drinking water filters: carbon block cartridges are often used in drinking water filtration systems to improve the taste, odor, 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 from premature wear of devices such as boilers, dishwashers, or washing machines.
In practice, this means more comfortable use of utility water and better operating conditions for the home installation. The carbon cartridge is often chosen as a simple and effective pre-treatment stage in solutions where a full reverse osmosis filter or a more advanced osmosis filter is not needed, but improving the sensory parameters of water is important.

Durable and thoughtful construction
- Two-piece 10" in-line housing, WodaRO® brand, providing reliable protection for your water installation.
- Consists of a transparent sump and a head with a 3/4" brass thread.
- Durable, high-quality housing ensuring safety and stable use.
- The transparent sump makes it easy to assess the condition of cartridge contamination.
The housing design has been created with everyday household use in mind. The transparent sump simplifies servicing and allows you to decide more quickly when to replace the cartridge, without guessing its wear level.
Double sealing system
- Equipped with two sealing O-rings, ensuring maximum product tightness.
- The seal also helps maintain pressure inside the in-line housing, preventing air from entering the system.
Double sealing increases operating safety and supports the stability of the filtration system. This is an important feature especially where the filter operates continuously as part of a domestic installation.

Air vent and flexible installation configuration
- The air vent allows pressure inside the housing to be balanced 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 installation, which translates into improved water quality and longer service life of the devices.
- It can be installed individually or connected in series, providing flexible adaptation to user needs.
The ability to expand the installation is important for users who plan additional filtration stages in the future. Such a housing can operate as a single filter or as part of a larger water treatment set.

FAQ
It is an in-line flow filter for installation on a cold water system. It can be used at the water inlet to a house or apartment, as well as before household appliances, to improve water quality and reduce the impact of contaminants on the installation.
Yes. The set includes one USTM BL10 carbon cartridge in the form of an activated carbon block.
The cartridge helps retain larger mechanical contaminants such as sand, rust, and sediment, and also adsorbs chlorine, selected organic compounds, pesticides, and some other chemical contaminants responsible for unpleasant water taste and odor.
No. The product is intended for cold water. The maximum operating temperature is 2-45 degrees Celsius.
The filter has a 3/4" connection and supports 10" cartridges, which gives great flexibility when selecting mechanical, specialty, and carbon cartridges.
The air vent helps equalize pressure inside the housing with atmospheric pressure. This reduces the risk of overloading filtering and sealing elements, and the filter can operate more stably.
The transparent sump helps by allowing visual assessment of the cartridge contamination level. In addition, the declared life should be taken into account: up to 14,000 liters or up to 6 months, depending on water quality and usage intensity.
Yes. The housing can be installed individually or connected in series, which makes it possible to create a more advanced water filtration system tailored to specific installation needs.
It is not the same solution. This flow filter improves water taste and odor and reduces chlorine and selected contaminants, while reverse osmosis is a much more advanced filtration method, usually used point-of-use, most often under the sink.
Choose a set or individual cartridges. Replacement intervals depend on the cartridge and operating conditions.
