3. Product Overview
The Stokk E1 is a compact countertop reverse osmosis water filter system designed for ease of use and portability.
The Stokk E1 countertop water filter system, shown in grey, actively dispenses purified water into its accompanying glass pitcher. The digital display indicates water quality readings.
This image illustrates the compact design of the Stokk E1 system, highlighting its dimensions (13.90 inches length, 6.77 inches width, 12.36 inches height) and key features such as a 5-stage RO filtration system, space-saving design, 0.0001 µm RO membrane, smart touchscreen, quick water supply, and mineral retention.
3.1 Filtration Stages
The Stokk E1 utilizes a 5-stage Reverse Osmosis filtration system to remove contaminants and enhance water quality:

- PP 5µm: Sediment pre-filter.
- Pre-C 0.5µm: Pre-carbon filter.
- RO 0.0001µm: Reverse Osmosis membrane for ultra-fine filtration.
- Post-C 0.1µm: Post-carbon filter for taste and odor improvement.
- Mineral: Remineralization stage to add beneficial minerals.
This image visually emphasizes the 0.0001 micron ultra-high accuracy of the Stokk E1's filtration, illustrating the minute size of particles that can be removed.
3.2 Remineralization Pitcher
The included glass pitcher is designed to enhance the purified water with beneficial minerals.
The image shows the glass pitcher designed to enhance water with beneficial minerals such as Sodium (Na+), Strontium (Sr2+), Calcium (Ca2+), Magnesium (Mg2+), and Potassium (K+), contributing to pH balance.
4. Setup Guide
4.1 Unpacking
- Carefully remove all components from the packaging.
- Verify that all parts are present and undamaged.
- Remove any protective films or packaging materials from the unit and filters.
4.2 Initial Placement

This image depicts the Stokk E1 water filter system in a kitchen setting, emphasizing its "No Installation Needed" feature. It highlights the convenience of simply plugging it in and using it, with low power consumption (20W) and wide voltage compatibility (100-240V).
4.3 First-Time Use and Flushing
- Fill the raw water tank with tap water.
- Plug the power cord into a suitable electrical outlet.
- The system will power on. Follow the on-screen prompts or press the 'Flush' button (if available) to initiate the initial flushing cycle. This process cleans the filters and prepares the system for use.
- Discard the water from the first two full pitchers dispensed. This ensures optimal filter performance and taste.
5. Operating Instructions

- The system will automatically dispense the selected volume of purified water.
5.3 Understanding the Display
The LED display provides real-time information:
- IN TDS: Shows the Total Dissolved Solids (TDS) level of the incoming tap water.
- OUT TDS: Shows the TDS level of the purified water. A lower number indicates higher purity.
- Filter Life Indicators (PPC, RO, C): These icons illuminate or change color to indicate the remaining lifespan of each filter. Refer to the maintenance section for replacement details.
- Flush Button: Used to manually flush the system, which can help extend filter life or improve water quality.
- Reset Button: Used to reset filter life indicators after filter replacement.
6. Maintenance
