## Questions & Answers

**Q: Are these the only filters i need to change?**
A: No. I believe there’s 4 filters total. Two are fairly frequently and the other two are yearly I believe

**Q: what is in the remineralizer? I cannot find on any website describing the contents of it.**
A: Makes the water taste like Arowhead bottled water. I don't like it.

**Q: Does the remineralizer in this product include the microbial filter, as shown on the cover image?**
A: Yes it does but you will have to buy the two Claryum Filters

**Q: Is that 24 hour purge correct?  That is not a good idea if you're on a well system.  I'm glad I saw this before purchasing the system.**
A: Instructions with the filters say let the tank fill after replacing the filters, drain the tank and refill. Should be good to go then.
