The A1 combines reverse osmosis with a compressor for cooling and a heating element, in a single box that needs no under-sink work. Its cold setting reaches 41°F, which Waterdrop compares to refrigerator-grade water.
On the hot side, the listing says water arrives in about 3 seconds, up to 203°F. A touch panel picks temperature and volume, and a child lock stops anyone dispensing hot water by accident.
Day to day, the A1 keeps a 136 oz feed tank and a 61 oz waste tank. It also has night, off-home and altitude modes, plus TDS monitoring and a filter life reminder on the display.
Filtration is seven stages at 100 GPD with a 2:1 pure-to-drain ratio, and the unit is listed as NSF/ANSI 372 certified. The A1-CF filter lasts 6 months and the A1-RO filter 12 months.
The A2 is a lighter 5-stage alternative at 100 GPD with 3:1 drain ratio, and the M6CG adds minerals. Seasonal sale pricing on the A1 shows beside the listing.
