## Questions & Answers

**Q: Is the blue outside containers just for looks?**
A: Are you asking if the 'blue' color has a function like UV protection? 
I believe it's just for easy detection as the color usually represents water.

**Q: What is the nsf rating for this system? we have lead in our city water and need a minimum rating of nsf-53.**
A: Not sure on the rating , but I had our water tested after I installed the system and had 0 ppm for lead

**Q: I just installed a wgb22b-pb. do the filters have to be installed in a special way--up side down or which way up and which way down?**
A: Hi,

The sediment filter has no real upside or downside and can be installed in the system either way but the specialty filter for Iron/Lead should be installed as shown in the picture on the listing . Please contact our office at 678-261-7611 if you have any additional questions.

Thank you,

iSpring Water Systems LLC

**Q: why does the title say it filters chloride but the manufacturer answered another question saying it does not filter chloride?**
A: Hi,

This system can remove Chlorine which is a component of chloride thus breaking up the composition of chloride and removing the chlorine aspect of this contaminant. Please contact our office at 678-261-7611 if you have any questions.

Thank you,
