Coffee and CO₂
The included Coffee Tray distributes 95 °C water in intervals inside a closed brewing chamber. It fits Melitta 1×2, 1×4 and 1×6; holder, filters, coffee and pot are not included.
The internal compartment accepts standard 425 g screw cylinders. Pink SodaStream Quick Connect cylinders do not fit. Large external bottles require a separate pressure regulator; the stated maximum is 4.5 bar.
Filter, UV-C and certifications
7-in-1-Filter mit Umkehrosmose und Remineralisierung; drei UV-C-LEDs, laut Hersteller rund 20.000 Betriebsstunden. The two TDS values show the water after the RO membrane and after remineralisation.
- • TÜV Rheinland, Zertifikats-ID 1111314292
- • WQA Gold Seal, geprüft nach NSF/ANSI/CAN 372-2020
Certifications apply to the properties tested. They do not validate every marketing claim. Filtration rates depend on feed water, temperature, filter age and operating conditions.
Sparkling water and replenishment
The 800 ml sparkling tank operates only while cooling is on. The manual states about 1.1 L regular or 0.8 L strongly sparkling per cycle. After 500 ml is dispensed and three minutes pass, replenishment takes roughly one to two minutes. Water below 15 °C binds CO₂ more effectively.
Remineralisation: reference values
For the 7-in-1 filter, the laboratory references include conductivity of 146 µS/cm, pH 7.0, calcium 18 mg/L, magnesium 4 mg/L and hardness 3.28 °dH. The optional 5-in-1 values are 47 µS/cm, pH 5.8, calcium 6.1 mg/L, magnesium 0.61 mg/L and hardness 1 °dH. These are reference values; contact time, feed water and mains operation affect the result.
Included items and limitations
Included are the preinstalled 7-in-1 filter, external tank, low and high drip trays, Coffee Tray, water connector, drain clamp, hoses, accessories and manual. CO₂ cylinder, pressure regulator and coffee equipment are not included.
Manufacturer filtration figures in detail
OsmoFresh states these average figures: PFAS 99.9%, microplastics and bacteria above 99%, lead 96–98%, nitrate 94–96%, fluoride 93–95%, iron, aluminium, copper, manganese and silver 97–99%, mercury and chromium 95–98%, cadmium 95–97%, nickel and zinc 95–97%, sulphate and phosphates 97–99%, cyanide 97–98%, bromine 93–96%, chloride 85–95%, silicates 85–90% and silicic acid 90–95%.
These figures are not guaranteed. Feed water, pressure, temperature, filter age, storage and production variation affect performance. Filtration figures do not establish a medical benefit.
Before setup and longer breaks
After transport, the manual says to leave the unit upright and switched off for at least 24 hours. Allow about 10 cm ventilation at each side. In tank mode, remove the 5 L tank when the red drop appears, discard remaining water and refill; do not top up. Use holiday mode after more than three days; the manual recommends replacing the filter after more than three weeks.
Fusion Pro 2 questions and answers
Does the Fusion Pro 2 need a water connection?
No. It can use the 5 L external tank or connect to cold water and a drain. Both operating modes must not be combined.
Can I start with the tank and connect it later?
Yes. Select the mode on the display; fixed operation requires properly installed inlet and drain lines.
Which CO₂ cylinders fit?
The internal compartment accepts standard 425 g screw cylinders with a trapezoidal thread. Pink SodaStream Quick Connect cylinders do not fit.
Is a CO₂ cylinder included?
No. The pressure regulator needed for a large external cylinder is also not included.
How much sparkling water can it dispense?
The manual states about 1.1 L regular or 0.8 L strongly sparkling. Replenishment starts after dispensing 500 ml followed by a three-minute pause and takes about one to two minutes.
How does the filter-coffee mode work?
It dispenses 95 °C water in intervals. The Coffee Tray distributes the flow above the filter holder and fits Melitta 1×2, 1×4 and 1×6. Holder, filters, coffee and pot are not included.
How often is the filter replaced?
The manual says after 12 months at the latest, or sooner with poor feed water, reduced flow or unusual TDS readings.
What do the two TDS readings mean?
One is taken after the RO membrane and one after remineralisation. TDS is a total dissolved-solids reading, not a complete contaminant analysis.
How often should the external tank be cleaned?
OsmoFresh recommends about once or twice a week with lukewarm water and citric acid or its cleaning set. The tank is not dishwasher safe.
What matters before first use?
After transport, leave it upright and switched off for at least 24 hours, allow about 10 cm clearance at each side, then complete the guided setup and flush.
What is the wastewater ratio?
The stated tank-mode ratio is 4:1. The product page states 1:2 for mains operation; we reproduce that figure as a manufacturer statement without interpreting it.
Is it suitable for an office or motorhome?
The manufacturer positions it for homes and offices with 1–6 people. For motorhomes, check weight, 2,400 W peak power, secure placement, ventilation and water supply individually.

See more detailsWhy OsmoFresh stands out as a water filter brand
OsmoFresh is one of the few reverse osmosis manufacturers based in Germany that handles development, production, and support in-house. The Fusion systems demonstrably remove PFAS, microplastics, and heavy metals — documented through independent TDS measurements and lab analyses.
Compared to cheaper filter systems, the Fusion Pro and Fusion Ice offer remineralization after filtering — this ensures better taste and a balanced mineral profile. Benedikt has been using the Fusion Pro since October 2025 and documents the results in video reviews.

Real Water Test
Water Test: Tap Water vs. OsmoFresh Fusion Series
Real test results with 22 parameters – measured by Benedikt Keck
Test strip comparison: Left tap water with issues, right OsmoFresh Fusion Series – all parameters in optimal range.
Conclusion
The OsmoFresh Fusion Series reliably filters out almost all measured contaminants. While the tap water shows issues with several parameters (chlorine, hardness, heavy metals), the Fusion Series delivers consistently optimal values. A clear difference that is noticeable in taste and water quality.
Comparison Test: OsmoFresh Fusion Pro vs. Hydrofast C300 vs. Tap Water
Triple comparison with identical test strips: Both the OsmoFresh Fusion Pro and the Hydrofast C300 deliver nearly pure water – unlike tap water which shows clear issues.
After 9 Months of Long-Term Use: AQUANEXO 16-in-1 Quick Test
Left: Fusion Pro osmosis water, right: tap water – 16 parameters in a direct test strip comparison after 9 months of use.
Here you can see the direct comparison with the AQUANEXO test strips: on the left the water from my Fusion Pro, on the right my regular tap water. Of course a test strip is not a laboratory analysis and the values should not be interpreted down to the last decimal. But as a rough comparison, the result is pretty clear.
My tap water shows noticeably stronger color reactions, especially for hardness, limescale, alkalinity and general mineralization – the water in my home is very high in limescale. The strip for the Fusion Pro water looks far less reactive: the system strongly reduces dissolved substances and then adds minerals back in. For me, this test confirms even after nine months that the Fusion Pro's water quality is still excellent.
| Parameter | Fusion Pro (left) | Tap water (right) | Assessment |
|---|---|---|---|
| pH value | rather neutral to slightly alkaline | somewhat more alkaline | Both unremarkable; tap water reads slightly higher. |
| Alkalinity / buffering | clearly lower | clearly higher | Typical: osmosis water contains fewer dissolved substances after filtration. |
| Total hardness / limescale | clearly reduced | visibly higher | Matches the limescale-rich tap water in this test very well. |
| Chlorine / free chlorine | unremarkable to very low | also not strongly elevated | No clear indication of high chlorine. |
| Nitrate / nitrite | unremarkable | unremarkable to slightly elevated at most | No problematic value visible. |
| Heavy metals / metals | unremarkable | no clearly conspicuous extreme values | Only roughly assessable with test strips. |
| General mineral/salt load | clearly lower | clearly higher | Tap water shows overall stronger color reactions. |
Important note: test strips only provide rough guidance, not a laboratory analysis. This evaluation is a visual quick-test comparison, not an exact lab-grade measurement.
Test methodology: Standardized 22-parameter water test strips with color comparison. All parameters measured under identical conditions. Test conducted October 2026.

Fusion Pro
The all-in-one premium unit: still, medium, sparkling, ice-cold, hot up to 95 °C.
€1,290
- Sparkling medium + intense with standard CO₂ cartridges (or external 2 kg bottle).
- Ice-cold 4 °C to boiling 95 °C – measured directly at the outlet.
- 7-stage filtration + triple UVC-LED disinfection: PFAS, nitrate, bacteria, viruses, chlorine, drug residues.
- Best fresh-to-waste-water ratio of any unit I have ever tested.
- Vacation mode + Eco mode (cooling off at night, automatically on in the morning).
"For me the most complete device OsmoFresh has ever built. It does everything – except ice cubes."
Critique: the remineralization filter can no longer be removed if you really want "empty" water with TDS 2.
→ Watch the Fusion Pro videoFusion Ice
Premium with ice cubes – my personal everyday favourite.
€899
- 30.5 × 41.5 × 45.5 cm, 17.5 kg, 4.5 l external tank → ~3 l pure water, only ~1.2 l residual.
- TDS measured: tap 260 ppm → Fusion Ice 76 ppm (remineralized; 20–100 ppm is normal).
- Power measured: 1.7 W standby, ~85–120 W cooling + ice, peak ~2,200 W hot water.
- Noise: 48 dBA standby, 54 dBA at 1 m distance during ice production.

- Crystal Cube: fresh ice every 10 min, up to 90 cubes (~450 g) stored.
- 800 ml in 1 min 18 s – or instantly from the built-in 2 l carafe.
"After one week the Fusion Ice already takes so many little tasks off my plate that I don't want to be without it."
Critique: at 17.5 kg it is big and heavy – overkill for single households. The carafe must always be inserted, otherwise the outlet does not work.
→ Watch the Fusion Ice videoFusion Air
Slim countertop unit – the direct successor to the Quella Pro.
Compact, no CO₂
- 19.5 cm narrow – 0.5 cm slimmer than the Quella Pro.
