To keep your R/O System functioning at an optimum level, its filters need to be changed annually. The AlkaViva RO Annual Replacement Package includes a Sediment Filter, a Carbon Block Filter, an Inline Re-mineralizing Filter, and a Taste & Odor Filter.
Additionally, the RO Membrane needs to be replaced every two years.
If you purchased your RO system before 4/11/12 and you have not ordered replacement filters since, please note that in the comments section. The RO system was upgraded then, and we want to make sure you receive your free upgrade kit.
The company will stand by their product if it's defective. They will repair it or replace it for free if it's defective. However, no returns are allowed for filters through which water has been poured.
