Frequently Asked Question

DI stands for deionization. This de-mineralizing filter takes the full size RO to a higher level of filtration. It is an excellent inline filter, especially for those who live in areas with exceptionally high levels of Total Dissolved Solids (TDS) in their tap water. The post deionizer takes the small percentage of contaminants that the membrane could not remove and filters this to greater than 99.99% pure. It will give you close to 0 ppm TDS. You cannot live on DI/distilled water alone, but you can drink it as long is it is not the only water you consume, as you need to absorb nutrients from water.
