RO-90 Reverse Osmosis Drinking Water Filter System vs AQUASURE Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System: which is safer?

Where these two actually differ

• We flag Bacterial growth in stagnant filter cartridges and Carbon filter dust or activated charcoal particulate on the APEC Water Systems and not on the Aqua Guard.
• 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 APEC Water Systems.
• The APEC Water Systems is Carbon/RO membrane filters, plastic housing where the Aqua Guard is RO membrane, carbon filters, stainless steel 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.
