Pitcher vs Plus 30 Cup Dispenser: which is safer?

Where these two actually differ

• We flag Bacterial growth in filter housing if unmaintained, Filter composition leachables (unspecified binders and media), Thermal shock cracking of borosilicate glass and Contaminant removal efficacy not independently verified on the LARQ and not on the PUR.
• We flag Bacterial growth in filter media if not maintained, Ion-exchange resin particles or fragments in filtered water, Activated carbon dust or fines in first use and Reduced contaminant removal if filter exceeds rated capacity on the PUR and not on the LARQ.
• The LARQ is borosilicate glass pitcher, replaceable activated carbon filter where the PUR is activated carbon filter, plastic dispenser housing, which is most of the difference in these two grades.
• These two are 5 points apart, close enough that price and fit should decide it rather than our grade.
