AQUASURE Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System vs G2 Reverse Osmosis System for Home: which is safer?

Where these two actually differ

• We flag Bacterial and microbial growth in housing and filters, Activated carbon filter degradation and dust release, RO membrane integrity failure and microbial breakthrough and Tubing and connector leakage or degradation on the Aqua Guard and not on the Waterdrop.
• We flag Bacterial growth in storage tank or tubing, Carbon filter particulate release, Reverse osmosis membrane rupture releasing unfiltered water and Missing or inadequate product testing documentation on the Waterdrop and not on the Aqua Guard.
• The Aqua Guard is RO membrane, carbon filters, stainless steel housing where the Waterdrop is RO membrane, carbon filters, plastic 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.
