HHBB20A Aquafilter is a water treatment station on a steel frame, based on 2 housings in the BIG BLUE 20" standard. It is a solid foundation for building a home filtration system with cartridges selected according to water quality (e.g., mechanical, softening, de-ironing, carbon). The set includes 2 pressure gauges that facilitate monitoring of pressure drop and 2 centering discs BACinix withnanosrebrem.
HHBB20A Aquafilter double Big Blue 20" water filter is a solid station for water treatment and building a home water filtration system on a steel frame. The set is based on 2 BIG BLUE 20" housings, allowing you to select the appropriate filter cartridge for the water quality in your home, including issues such as hard water, iron, or chlorine. The freestanding design, 2 pressure gauges, and 2 BACinix antibacterial centering discs make it a practical and flexible base for an efficient water filter in a household installation.

HHBB20A Aquafilter is a professional water treatment station built into a steel frame. This design allows the unit to be conveniently placed on the floor, without the need to mount it to a wall or other vertical surface.
The set is built on 2 filtration columns in the BIG BLUE 20" standard, allowing the system to be configured precisely to the water parameters and the type of contaminants present. This solution is especially convenient where the water composition requires individual selection of filtration and treatment cartridges.
The system is built with 2 BIG BLUE 20" filtration columns. This configuration makes it possible to use different cartridge combinations matched to the issues present in the water.
Hard water, limescale buildup:
Excess iron in water:
Excess chlorine in water:
The HHBB20A model is a system base that allows cartridges to be selected for specific water parameters. The appropriate filtration set should be matched to the actual issue, such as hardness, the presence of iron, or chlorine.

The set includes 2 pressure gauges that allow pressure values to be read. This practical solution makes it easier to monitor the operation of the set and helps determine when cartridge replacement is necessary.
The housing has a 1-inch thread.
The set includes 2 centering discs made using BACinix™ antibacterial technology, which uses nanosilver. This solution has a bacteriostatic effect, limiting the growth of microorganisms inside the filtration system, which helps extend operating time and protects the system against microbiological contamination.
The double Big Blue 20" filter works well as an advanced base for filtration and treatment of utility water in the home. It can operate as part of an installation responsible for preliminary water purification before further devices, improving the comfort of using fixtures and protecting the installation against mechanical deposits.
Thanks to the option of selecting cartridges, the system can be configured for different needs. It is not a classic osmotic filter or a reverse osmosis system, but a solution intended for inline water filtration in a household installation, which can be an important part of a broader treatment system.
The frame allows the device to be freely placed on the floor. The presence of pressure gauges makes it easier to continuously monitor pressure drop and thus plan the replacement of consumable cartridges.

It is a double water treatment station on a steel frame, intended for building a home water filtration system. It allows cartridges to be selected for specific water quality issues, such as mechanical sediment, hardness, iron, or chlorine.
The model works with cartridges in the BIG BLUE 20" standard. For example, a mechanical and softening set can be used for hard water, a mechanical and iron-removal set for excess iron, and a mechanical and carbon set for excess chlorine.
The set is a system base and includes the housings, frame, pressure gauges, housing wrench, and antibacterial spacer rings. Filter cartridges are selected separately according to water parameters.
The pressure gauges allow pressure to be read and help monitor pressure drop in the system. This makes it easier to assess when the filter cartridges should be replaced.
The centering discs facilitate correct cartridge installation, help maintain its correct position while tightening the elements, and reduce the risk of cartridge damage. Additionally, BACinix technology with nanosilver supports antimicrobial protection.
No. The steel frame allows the device to be freely placed on the floor, without the need to mount it to a wall or other vertical surface.
The filter width is 560 mm, depth is 220 mm, and height is 730 mm or 790 mm with pressure gauges.
No. The HHBB20A is not a reverse osmosis device, a reverse osmosis filter, or a reverse osmosis system. It is an inline filtration system based on BIG BLUE 20" housings, where performance and function depend on the selected cartridges.
