Who should buy which
Renters and anyone who needs true reverse-osmosis filtration without under-sink installation, especially where tap water tests high for TDS, PFAS, or heavy metals.
Your water is already low-TDS and clean (a mineral-retaining ceramic system fits better), or you want a permanent built-in and can plumb under-sink (Frizzlife sells those too).
Homeowners who have run a Tap Score test (or know their municipal water has flagged contaminants) and want to fix the upstream water-quality layer with a permanent RO installation. Also buyers maintaining existing RO systems who need replacement filters at competitive prices.
You are renting and cannot install under-sink hardware (countertop systems work but produce limited volume). Or you have not yet tested your water and might find a $50 carbon pitcher solves your specific contaminant profile.
