The Aries AF-20-4040 is a 20"x2.5" mixed bed deionization filter cartridge engineered to deliver ultra-pure water with resistivity greater than 14 megohm-cm for laboratory, misting, and humidification systems. This low odor resin formulation is specifically designed for applications where odor-sensitive final water quality is critical.

COMPATIBILITY & APPLICATIONS
Where This Filter Excels
The AF-20-4040 is ideal for misting systems, humidification equipment, ultrasonic cleaners, steam irons, hydroponics, and any application requiring ultra-pure water with minimal residual odor. It fits standard 20-inch housings and is commonly used in both whole-house water polishing systems and point-of-use laboratory applications. The low odor resin formulation makes it particularly suitable for environments where even trace resin smell is unacceptable, such as commercial humidifiers and air quality systems.
💧 Mixed bed DI cartridges exhaust over time as they remove ionic contaminants. Monitor TDS levels with a meter to know when regeneration capacity is depleted—once resistivity drops below your target threshold, it's time to replace the cartridge.
