Aries (AF-20-3327-BB) 20"x4.5" Big Blue 80 oz. Phosphate Filter
Aries AF-20-3327-BB 20"x4.5" Big Blue Phosphate Filter
80 oz. sequestering phosphate cartridge for scale prevention, corrosion control, and iron suspension in whole-house applications
The Aries AF-20-3327-BB is an 80 oz. phosphate filter designed for 20"x4.5" Big Blue housings, delivering comprehensive scale, corrosion, and iron control for whole-house water systems. This specialty cartridge uses food-grade sequestering phosphate to prevent mineral precipitation, protect metal surfaces, and keep dissolved iron suspended, extending the life of water heaters, appliances, and plumbing.
Triple-Action Water Conditioning
Scale Prevention
Keeps hardness particles separated so they cannot precipitate and form deposits when heated. Effective for hardness levels up to 15 grains per gallon without salt or backwashing.
Corrosion Control
Forms a protective coating on all metal surfaces, safeguarding pipes and equipment against acidity, alkalinity, hardness, chloride, and other corrosive factors. Works across pH range 6.5 to 9.0.
Iron Sequestration
Keeps dissolved iron up to 1 ppm suspended in solution, preventing precipitation that causes rust staining and discoloration on fixtures, laundry, and surfaces.
80 oz. Capacity
High-volume phosphate charge provides extended service life in residential and light commercial applications. No electricity, salt, or backwash required.
Food Service Safe
NSF-certified food-grade phosphate ideal for restaurants, cafes, and commercial kitchens. Protects water heaters, steamers, dishwashers, and beverage equipment.
Standard Big Blue Fit
Fits all standard 20"x4.5" Big Blue filter housings from major manufacturers. Simple drop-in replacement for existing whole-house systems.
Whole-House Specialty Filtration
The Aries AF-20-3327-BB is designed for 20-inch x 4.5-inch Big Blue filter housings used in whole-house water treatment systems. Ideal for homes and businesses with moderate hardness (up to 15 gpg), low-level iron issues (up to 1 ppm dissolved), or pH conditions between 6.5 and 9.0 that contribute to scale buildup or corrosion. Common applications include pre-treatment for tankless water heaters, protection for appliances and plumbing, food service equipment conditioning, and situations where salt-free scale control is preferred. Compatible with standard Big Blue housings from brands including Pentek, Culligan, GE, Whirlpool, and Hydronix.
