AQUASURE Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System vs G3P600 Under Sink Reverse Osmosis System: 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 Plastic housing leachables (BPA/BPS potential), Bacterial growth in filter cartridges, Membrane degradation from heat or UV exposure and Off-gassing from plastic housing during initial use on the Waterdrop and not on the Aqua Guard.
• The Aqua Guard is RO membrane, carbon filters, stainless steel housing where the Waterdrop is Reverse osmosis membrane, activated carbon, plastic housing (unspecified resin), 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.
