Polyphosphate crystals for dishwasher and laundry filter

Polyphosphate crystals dissolve in water and effectively cover elements such as iron, calcium, magnesium, etc.

making it impossible for these elements to "precipitate" out of the water and create the well-known problems associated

with "hard" water, such as scale formation in pumps, washing machine resistors, etc.

They protect devices and increase the effectiveness of detergents by 30%.

The package contains 250 grams of material, sufficient for three refills of the AQUA-FILTER washing machine filter.
