Description
1" Whole House Flow Water Filter + Carbon Block Cartridge BL10 USTM is a practical water filter for installation on cold water at the entry point to a house, apartment, or before selected household appliances. The set forms a complete water filtration system with a 10" housing and the BL10 USTM carbon cartridge, which improves water taste and odor and helps reduce chlorine and selected organic contaminants. This solution supports everyday water treatment, and thanks to the 10" standard it also allows the use of various types of filter cartridges adapted to the needs of the installation.

1" flow-through housing filter for home use and installation protection
This in-line water filter has been designed for operation on a cold water installation. It works both as a filter at the entry point to a house or apartment and as protection for expensive household appliances. Thanks to its robust construction and the included carbon cartridge, it improves water use comfort and helps protect the installation against contaminants.
The set includes seals and a mounting wrench, which makes installation and later servicing easier. The kit also includes the BL10 USTM carbon cartridge in the form of an activated carbon block.

Main applications
- Ideal for installation on the pipe supplying cold water to an apartment or before expensive household appliances.
- Can support the protection of devices such as boilers, dishwashers, or washing machines against contaminants present in water.
- Works with a wide range of mechanical, specialist, and carbon cartridges available on the market.
- The set includes the BL10 USTM carbon cartridge.
- Can be installed individually or connected in series, making it easy to expand the installation with additional filtration stages.
As a result, the housing can serve as a standalone water filter or as part of a larger filtration system. In practice, it is a good complement to home installations, including those where an advanced water treatment system, osmotic filter, reverse osmosis filter, reverse osmosis, or reverse osmosis system is used at the drinking water tap.
How the BL10 USTM carbon cartridge works
The set includes a filter cartridge in the form of a carbon block. This solution combines mechanical action with the adsorption properties of activated carbon, improving water quality in everyday use.
Cartridge operation
- 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 substances, chlorine, pesticides, industrial pollutants, and other chemical compounds.
- Improved water odor and taste: thanks to the ability of activated carbon 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 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 water taste and smell.
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 installation against contaminant buildup and against premature wear of devices such as boilers, dishwashers, or washing machines.
Housing construction and ease of use
The two-piece 10" housing, by WodaRO®, provides reliable protection for the water installation. The design has been prepared with convenient servicing and stable operation in home filtration systems in mind.
- Consists of a transparent sump and a head with a 1" brass thread.
- The durable, high-quality housing ensures safe and stable use.
- The transparent sump makes it easy to assess the level of cartridge contamination.
Double sealing system and air vent
Leak-tightness and safe operation of the filter are crucial in a domestic installation. This model has been equipped with solutions that increase reliability during everyday use.
- Equipped with two sealing O-rings, ensuring maximum product tightness.
- The gasket also helps maintain pressure inside the housing, preventing air from entering the system.
- The air vent allows pressure inside the housing to be balanced with atmospheric pressure, eliminating the risk of damage to filtration or sealing components.
- Thanks to the presence of the air vent, water filters and filter housings can operate more efficiently, regardless of operating conditions and water system pressure, which translates into improved water quality and longer service life of the devices.

Installation and kit contents
