Big Blue 10-inch Big Blue Phosphate Filter for Scale Prevention

Contains 7 lbs. of slow-melt polyphosphate that dissolves slowly in water to inhibit scale and rust build-up. This type of treatment is recommended for use with ice machines, coffee and vending machines, food service equipment, water heaters, air conditioning equipment and many other types of water processing equipment.

Hardness particles are kept separated so they cannot precipitate and form deposits when heated. Best results are achieved at hardness levels of 15 GPG or less.

A protective coating is formed on all metal surfaces, safeguarding against acidity/alkalinity, hardness, chloride and other factors which effect the corrosion of water equipment and pipes.

Dissolved iron, up to 1ppm, is kept suspended in solution (sequestered), preventing dissolved iron from precipitating, which would cause staining and discoloration.

The filter typically treats around 50,000 gallons of water before needing replaced. With the typical 4-person household, this would be about 6 months. Filter life can vary depending on many factors, including water usage, hardness level, iron level, and other contaminants.

Filter measures 20-inch long and 4.5-inch in diameter.

Fits in all standard 10" Big Blue filter housings.
