High TDS reading on new filters

[Scribe]

Yeah I thought the same thing about others who sell spectra pure filters. Who knows how they are stored. Again thanks for all the help.

if you just changed filters, and your TDS output is at 10-20 instead of 0, most likely your DI filter is upside down. Make sure the side with the black gasket is facing up.
