How does reverse osmosis work?
It pushes your water through a membrane fine enough to hold back dissolved metals, PFAS, fluoride and most of what a pitcher or fridge filter lets through. A tank under the sink keeps the purified water ready, and the system runs on your water pressure alone.
Is reverse osmosis water bad for you?
RO takes the minerals out with the contaminants. Drink it as it is, or choose the Hydration Stack (or add the Sango Coral to the RO you have): calcium, magnesium and over 70 ocean-derived trace minerals go back in, nothing synthetic.
Which system should I buy first?
If you want water that tastes like spring water, the Hydration Stack. If you want the most certified purification and the minerals can wait, the GoodFor 8500. If you want certified drinking water for less, the GoodFor 7000.
What is the difference between the GoodFor 7000 and 8500?
The 7000 is certified to NSF/ANSI 42, 58 and 372. The 8500 adds 53 (PFAS, VOCs) and 401 (pharmaceuticals, BPA). If PFAS or pharmaceuticals are on your list, it is the 8500.
Why does the Hydration Stack cost so much more than the 8500?
Because the 8500 is inside it, along with two more systems: the Sango Coral, which puts the minerals back, and the UMH Pure, which structures the water. Bought on their own, the three cost more than the Stack does.
Do I need a plumber?
Most plumbers and handymen install one in about an hour. If your plumber has a question, our plumbers talk to your plumber. In San Diego, Orange, Riverside, Los Angeles, Houston, Austin, Tampa and Miami, we install.
How often do the cartridges change?
About every two years for the 8500 and the Stack, 12 to 18 months for the 7000's carbon, 6 to 12 months for the Pur-Alk. The TDS meter in the box tells you when.
Other systems say 14 stages and 0 ppm. Why four stages and 99%?
Stages count parts. 99% is the number the GoodFor 8500 is certified to by the WQA. No one in this industry should claim 100% of anything.
Can I return it?
Unused, in original packaging, within 30 days.
