The FI-DI20-BB deionization cartridge is designed to remove nearly all electrically charged contaminants (cations and anions) from the water. It is often used as a post filter with reverse osmosis and activated carbon filtration systems to produce ultra-pure water although it is also common to use as stand-alone filter. The FI-DI20-BB is an affordable, eco-friendly choice when it comes to removing cations and anions from the water. It has capacity of 25,000 ppm (mg/L) and fits in 20 in. standard whole house big housings. To calculate how many gallons the deionization cartridge can treat for the cations and anions in your source water, take capacity level (25,000 ppm for 20 in. deionization cartridge) and divide it by the electrically charged contaminants level from your water before it enters the filter. For example, if the electrically charged contaminants level in your water is 0.5 ppm per gallon it can treat up to 50,000 Gal. (25,000 ppm/0.5 ppm per gal) for 20 in. deionization cartridge. It removes nearly all electrically charged contaminants (cations and anion) from the water, as well as Nitrates Phosphates Silica Ammonia and other charged contaminants. Reusable cartridge reduces plastic waste.
