Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System vs Premier Series AS-PR75A 75 GPD 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 Plastic leaching from housing and tubing, Bacterial biofilm in filter cartridges and membrane, Microplastics from filter degradation and VOC off-gassing from plastic housing on the Aquasure and not on the Aquasure.
• The Aquasure is RO membrane, carbon filters, stainless steel housing where the Aquasure is Reverse osmosis membrane, plastic housing, carbon/activated carbon filter media, which is most of the difference in these two grades.
