The Home Master TMAFC-ERP Artesian is a 7-stage under-sink reverse osmosis system that removes up to 99% of contaminants while adding calcium and magnesium for improved taste and alkaline pH. It features a patented 2-pass remineralization process and an optional permeate pump that reduces wastewater to a 1:1 ratio. Ideal for households seeking high-purity, remineralized drinking water with minimal maintenance.

The iSpring RCC7 is a robust 5-stage under-sink reverse osmosis system certified by NSF/ANSI 58, designed to remove up to 99% of over 1,000 harmful contaminants. It offers a high 75 GPD production rate without requiring a power source, making it a reliable choice for large households. However, it lacks the remineralization and UV sterilization features found in more advanced models.
