Scale reduction filter for water heater-boiler Q5" with polyphosphate crystals, to protect devices from salt deposition. The filter screws directly onto the supply of each device, without requiring specialized installation. Softens water, protects against salts, and extends the lifespan of the device by preventing their deposition.

Saves energy by keeping the internal circuits of the devices clean, resulting in better performance. At the same time, it prolongs their lifespan by preventing the known damages caused by salts.

The polyphosphate crystals dissolve in water and coat elements such as iron, calcium, magnesium, etc. This makes it impossible for these elements to "precipitate" out of the water and create the known problems associated with "hard" water, such as the formation of salts in internal circuits, pumps, resistors, and other metallic parts.
