Is the blue outside containers just for looks?

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.

What is the nsf rating for this system? we have lead in our city water and need a minimum rating of nsf-53.

Not sure on the rating , but I had our water tested after I installed the system and had 0 ppm for lead

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?

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

why does the title say it filters chloride but the manufacturer answered another question saying it does not filter chloride?

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, iSpring Water Systems LLC
