AQUASURE Premier Series 75 GPD Under Sink Reverse Osmosis Water Filtration System vs HydroGuard HDGT Undersink Reverse Osmosis Water Purification 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 Aqua Guard.
• We flag Bacterial growth in filters if maintenance neglected, Tubing degradation over time and Mineral scale or biofilm in storage tank (if model includes one) on the Aqua Guard and not on the Aqua Guard.
• The Aqua Guard is RO membrane, carbon filters, stainless steel housing where the Aqua Guard is RO membrane, carbon filters, polypropylene/polyethylene 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.
