Buying Guide: Key Purchase Considerations
Filtration level and stage count: Higher-stage systems (7–9 stages) typically remove more contaminants and may include remineralization to improve taste.
Installation type: Under-sink models require plumbing, while countertop or portable units offer flexibility for renters or space-constrained kitchens.
Certification and standards: Look for NSF/ANSI 58 (RO systems) and NSF/ANSI 372 (lead-free components) for reliability and compliance.
Remineralization: If you want balanced minerals and better taste, choose systems with a remineralization stage or AK/mineral boost.
Waste water ratio: Models with higher pure-to-drain ratios consume less water. Consider your household water usage and waste considerations.
Electrical dependence: Some countertop units require power or auto-flush features; factor in your access to outlets and energy use.
Maintenance and filter life: Check filter replacement intervals, availability of compatible filters, and ease of installation to minimize downtime.
