Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System vs Premier Series AS-PR75A 75 GPD 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 Aquasure and not on the Aquasure.
• We flag Bacterial growth in filter housing and cartridges, Plastic housing leachates (additive migration), Microplastics from filter cartridge degradation and Pressure tank corrosion (if included model) on the Aquasure and not on the Aquasure.
• The Aquasure is RO membrane, carbon filters, stainless steel housing where the Aquasure is RO/carbon filter cartridges, plastic housing, which is most of the difference in these two grades.
