Filtration Stages and Contaminant Removal
The number of filtration stages is a critical factor when choosing an RO system. More stages generally mean better contaminant removal, as each stage targets different impurities. The APEC ROES-50 uses a 5-stage process that includes sediment, carbon block, and RO membrane filters, effectively removing up to 99.99% of contaminants like arsenic, lead, fluoride, chlorine, and heavy metals.
This level of filtration is especially important for households concerned about PFAs and microplastics, which are increasingly found in municipal water supplies. A system with advanced stages ensures that your drinking water is not only safe but also great-tasting.
