Waterdrop K19 Countertop Reverse Osmosis System – Installation-Free
The K19 is a countertop reverse osmosis system that gives you RO-grade water without touching your plumbing. Fill the tank, plug it in, and it dispenses on demand – ideal for renters, apartments, offices and RVs where an under-sink install is not an option.
Why Choose the K19?
- No Installation: No drilling, no fittings, no plumber. Fill the tank and plug it in.
- 6-Stage Filtration with RO: A 0.0001µm RO membrane reduces TDS, nitrate, fluoride, arsenic, lead, copper, chromium-VI, chlorine, chloroform and turbidity.
- UV Sterilization: Reduces 99.9% of bacteria, verified by third-party laboratory testing.
- Four Preset Volumes: Dispense 4, 8, 16 or 32 oz at a touch instead of guessing.
- 170 oz Feed Tank: Large enough for a family's daily drinking water between refills.
- Smart Display: Live TDS reading plus a filter-life reminder.
- One Filter, Once a Year: A single 6-in-1 composite cartridge, changed annually via a pull-out door.
- 3:1 Pure-to-Drain and Quiet Running: Auto-standby after 30 seconds, and quiet enough to leave in a bedroom or studio.
Certified Performance
Certified to NSF/ANSI 42, 58 and 372 for the reductions specified on its Performance Data Sheet and for low lead content.

Frequently Asked Questions
-
Q: Do I really not need to install anything?
A: Correct. It is plug-and-play on any countertop – kitchen, office, RV or workshop. -
Q: How often will I refill the tank?
A: The 170 oz feed tank covers typical daily household drinking water. The screen shows L1 when it is time to lift and refill. -
Q: How often do filters need changing?
A: Once a year. The 6-in-1 composite cartridge swaps out in about three seconds through the pull-out door. -
Q: Does it reduce TDS?
A: Yes. Unlike gravity carbon filters, the RO membrane reduces dissolved solids, and the display shows you the live TDS figure.
If you want RO water but cannot modify the plumbing, the K19 is the system that fits. For a permanent under-sink install, see the Waterdrop X Series.
