1" WATER FILTER OTTONE, equipped with a brass head and polyphosphate dispenser, effectively protects water installations and household appliances from limescale buildup, extending their lifespan and improving operational efficiency.
1" Water Filter for Washing Machine Dishwasher Softener OTTONE is a durable water filter designed to protect household appliances and plumbing systems against limescale buildup. Thanks to the polyphosphate dispenser, it supports water treatment at the supply point for a washing machine or dishwasher, reduces the deposition of calcium and magnesium carbonates, and improves operating conditions for the equipment. It is a practical element of a water filtration system that helps extend appliance lifespan, increase detergent effectiveness, and reduce operating costs.

The 1" water filter with a polyphosphate dispenser was designed to protect water systems and household appliances against the negative effects of hard water. Its operation focuses on reducing limescale buildup, which over time can impair appliance performance, increase energy consumption, and lead to costly failures.
The polyphosphate filter media helps neutralize the calcium and magnesium carbonates responsible for scale formation. In practice, this means better protection for heating elements, water lines, and components operating in a washing machine or dishwasher. The filter therefore supports not only the current operation of the appliances, but also their longer and more trouble-free use.
The head and connections made of brass provide high durability, corrosion resistance, and reliability during long-term use. This solution is especially important where the filter operates continuously in a water system and must maintain tightness and resistance to daily loads.
The extended filter working surface supports effective removal of contaminants while also helping to extend the service life of the filter cartridge. This translates into less frequent maintenance and more convenient use.
Polyphosphate reduces the buildup of compounds responsible for scale formation. As a result, pipes, fittings, and appliance components are better protected against deposits that could reduce the efficiency of the entire system.

Reducing the impact of hard water allows detergents to work more effectively. This helps reduce the amount of washing and cleaning products used while maintaining good washing and dishwashing performance.
The filter helps protect washing machines and dishwashers from scale buildup on working components. This is important support for the daily operation of the appliances, which may translate into longer service life, better efficiency, and lower energy and water consumption.
The OTTONE model combines mechanical protection with anti-scale action. The 100 µm filter mesh size allows it to retain fine contaminants present in the water, while the filter cartridge based on polyphosphate and polyamide supports protection against the deposition of calcium and magnesium carbonates.
This operating principle makes the filter a very good point-of-use safeguard for household appliances. It is not a reverse osmosis filter, osmotic filter, or reverse osmosis drinking water system, but a practical protective component installed before a washing machine or dishwasher where the priority is to limit limescale problems and improve appliance operating conditions.
The filter is intended to protect water systems and appliances such as washing machines and dishwashers. The maximum operating temperature is 30°C, so it should be used in accordance with its intended purpose and the operating parameters of the installation. To maintain effectiveness, it is advisable to monitor the condition of the filter cartridge and replace it after reaching its intended service life.

The filter is used to protect water systems and household appliances, especially washing machines and dishwashers, against limescale buildup and fine contaminants present in the water.
Thanks to the polyphosphate dispenser, the filter reduces the buildup of calcium and magnesium carbonates, which are responsible for scale formation. This helps protect appliance components, improve efficiency, and extend service life.
Yes. Reducing the impact of hard water can improve the performance of washing and cleaning agents, allowing effective washing and dishwashing with more efficient use of detergents.
The filter is equipped with a 1" connection, in line with the parameters of a model designed to protect a washing machine, dishwasher, and selected sections of the water system.
The head and connections are made of brass. This material provides durability, corrosion resistance, and reliability in everyday use.
The cartridge lifespan is 100–120 m³ for the 1" version. To maintain effective protection, it is advisable to monitor cartridge wear and replace it according to the intensity of use.
The maximum operating temperature is 30°C, the maximum operating pressure is 16 bar, the filter mesh size is 100 µm, and the flow rate is 3.5 m³/h for the 1" connection.
The set includes: a 1" filter with polyphosphate dispenser, a wrench, and an instruction manual.
No. This model is not a reverse osmosis system or an osmotic filter for preparing drinking water. It is a protective filter for household appliances and installations, designed to reduce limescale buildup and capture fine contaminants.
Ten filtr do pralki i zmywarki świetnie chroni urządzenia przed kamieniem. Montaż był szybki i prosty, a pierwsze prania już pokazują, że działa – w bębnie mniej osadu. Paczka przyszła na drugi dzień, dobrze zabezpieczona.
