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 Express Water 10-Stage RO System is a comprehensive under-sink filtration solution with alkaline remineralization and NSF 58 certification. It includes a 4-gallon tank to compensate for its slow flow rate, making it suitable for families. However, it requires adequate cabinet space and sufficient water pressure to operate effectively.
