Proof belongs to a specific test.
This library separates instrument measurements, controlled comparisons, visual demonstrations, and the JR East field study—so each result keeps its own method and boundary.
Ultrafine bubbles measured after 49 ft (15 meters) of piping.
For the representative BeLife NPS 3/4 (20A), Fuji Keiki reports an average count of approximately 18.1 million and an average diameter of approximately 142.9 nm under the stated 2025 test conditions.
Six visual comparisons from Fuji Keiki's published tests.
The first three visuals are high-resolution recreations of the published comparisons. The additional laundry and washbasin cards preserve the supplied source photographs within clean comparison frames. Every card remains attached to its documented setup and is not a universal performance promise.

Simulated fixture residue
Blue food coloring and starch syrup were used as simulated soil, then the fourth rinse was compared.
BeLife NPS 3/4 (20A) · 58.6°F (14.8°C) · 0.90 gpm (3.4 L/min) · approximately 23 ft (7 m) of piping

Oil-residue cleaning
Salad oil and white food coloring were used as simulated soil on a frying pan before a 30-second rinse.
BeLife NPS 3/4 (20A) · 50°F (10°C) · 1.3 gpm (5 L/min) · approximately 43 ft (13 m) of piping

Drain-pipe residue
Black toner was used as simulated soil in transparent acrylic piping before a 60-second water-flow comparison.
BeLife NPS 3/4 (20A) · 72.5°F (22.5°C) · 1.3 gpm (5 L/min) · approximately 43 ft (13 m) of piping

Laundry appearance after 10 months
Fuji Keiki compared garment appearance after repeated wear and washing under the same documented conditions.
BeLife NPS 3/4 (20A) · average 57.2°F (14°C) · 4.0 gpm (15 L/min) · approximately 16 ft (5 m) of piping · 0.71 oz (20 g) liquid detergent


Washer-drum self-cleaning observation
The simplified comparison shows the drum before testing and after 90 days of continued daily washing.
BeLife NPS 3/4 (20A) · average 57.2°F (14°C) · 4.0 gpm (15 L/min) · approximately 16 ft (5 m) of piping · 0.71 oz (20 g) liquid detergent per wash

Washbasin residue
Simulated soil made with starch syrup and food coloring was applied to both hands, then basin residue was compared after repeated hand washing.
BeLife NPS 3/4 (20A) · 53.6°F (12°C) · 0.53 gpm (2 L/min) · approximately 26 ft (8 m) of piping
Read each comparison in its own measurement frame.
These charts place the control and BeLife result side by side. The axis language changes with the test: normalized index, removal rate, or change from baseline. None of these figures is the JR East 55-day trimethylamine result.
Water-spot residue
Fuji Keiki reports improved removal versus tap water after two controlled drying intervals on a prepared bonnet panel.
Artificial potassium-chloride water spots · BeLife NPS 3/4 (20A) · 57.2°F (14°C) water · 70% humidity · 290 psi (2.0 MPa) · 4.5 gpm (17 L/min) · approximately 49 ft (15 m) of piping · SSM-21P surface salinity meter

Normalized residual index derived from Fuji Keiki's reported improvement figures; tap water = 100.
Ammonia reduction rate
Percent reduction in measured ammonia concentration after washing under the controlled setup.
Tap water reduced the measured concentration by 34.1%; BeLife water reduced it by 74.2%. The difference is 40.1 percentage points. This is not the JR East field-study outcome.
Odor removal rate
Five-test average removal rates reported for simulated ammonia odor in washer drums.
Reported remaining concentration was 23.8 ppm with tap water versus 8.0 ppm with BeLife water.
Foundation removal rate
Reported removal rates after a 30-second rinse under the supplied controlled conditions.
Ten participants; foundation applied to the backs of the hands; 104°F ±3.6°F (40°C ±2°C); 1.8 gpm (6.9 L/min); approximately 26 ft (8 m) of piping; BeLife NPS 3/4 (20A).
Moisture retention rate
Reported rates after the controlled foot-immersion procedure.
A test-specific moisture measurement. This presentation does not imply medical efficacy or clinical certification.
Temperature retention rate
Reported rates after the controlled foot-immersion and retention interval.
Eight participants; five-minute immersion followed by a five-minute retention interval. The values are test-specific surface-temperature retention rates.
The number, measure, and setup stay together.
