## Questions & Answers

**Q: How often do I need to replace the filters in this unit?**
A: Each filter has a rated life and you'll have to calculate how much you're using to figure out. A good rule of thumb is to replace the sediment filter the most often (as it starts looking dirty, prob 1-6mos). Change the carbon filters on a schedule because chlorine is the most dangerous thing to let through to the membrane (usually 6-12mos). Chlorine will quickly damage the membrane(most expensive to replace, usually 1-2yrs). Letting hot water run through the system opens the pores on the membrane and let's contaminants through. Also, when you change carbon filters, let them flush to the drain before connecting output to membrane (will keep carbon dust from settling in the membrane pores). The easiest way to check if you need to replace the membrane is with an inexpensive ppm/tds meter, you should be in the 0-50ppm range, depending on your starting ppms of the tap (collect sample before it reaches the mineralizer to test). Once ppms start creeping up, you need to change your membrane. You will need a ph tester to determine if the mineralizer is exhausted. Each filter really has it's own rate it wears out. I've worked with reef tanks and hydroponics most of my life so I help these tips help.

**Q: How much water is being wasted while filtering?**
A: As I did my research this one i found was about 1 to 1 so if I remeber correctly, please dont quote this but I did by this one becuase it wasted the least amount of water per gallon i looked at.  I have had it now for almost two years and still on the same filters and i use it for everything i can

**Q: What’s the difference between this one at 100 and the one at 50 they are ten bucks difference? Thanks**
A: The productivity rate is the difference, 100 GPD is a bit faster.

**Q: How do I know when to change filter?**
A: 6 month to a year it depends how many people use the filter during the day most people will change it every year
