AQUASURE Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System vs RCC7 5-Stage Under Sink Reverse Osmosis Drinking Water Filtration 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 iSpring.
• We flag Bacterial growth in unmaintained filters, RO membrane rupture and loss of filtration function and Installation leaks or cross-contamination on the iSpring and not on the Aqua Guard.
• The Aqua Guard is RO membrane, carbon filters, stainless steel housing where the iSpring is activated carbon & RO membrane filters, polypropylene 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.
