Seven-stage under-sink RO with alkaline remineralization
HW800 AlkaPro Tankless Reverse Osmosis
800 gallons a day, made on demand, with the minerals put back.
A tankless under-sink system: it makes water as you draw it rather than storing it, which takes back most of the cupboard a conventional RO occupies. Figures from NMWS's own published sheet.
