New Unit Flushing Guide
Before first use, follow these flushing steps to activate filters and clean pipes. The process takes about 30-40 minutes.
Step 1: Air Out Remove all packaging, take off the top cover and pure tank lid, and air out in a cool ventilated place for 12-24 hours. This dissipates the new-unit smell.
Step 2: Power On & Purify Fill the raw tank with municipal tap water to max line. Reassemble the pure tank, top cover, and raw tank. Plug in and purification starts. Wait ~10 minutes until the water light turns off.
Step 3: Drain Ambient Water (repeat 3-5 times) Place a heat-resistant container (2-3L) under the spout. Long-press "Dispense/Stop" for 5 seconds until screen goes black; the green light starts draining. It stops automatically when done.
Step 4: Flush with 45℃ Water (repeat 1-2 times) After purification completes, set temperature to 45℃, press "Dispense." Wait for automatic stop.
Step 5: Flush with 98℃ Water (repeat 1-2 times) After purification completes, set to 98℃, press "Dispense." Wait for automatic stop.
Step 6: Done After these steps, the unit is ready. For the first 3 days, run a drain cycle daily to fully activate filters. More flushing = better taste.
Water Marks on New Unit?
Because countertop purifiers are complex to manufacture, Bewinch runs 100% performance and water-safety testing before shipping. After testing, water lines are cleaned and test filters are replaced with new ones. Minor water marks may remain in the pump and valves. This is normal. Simply follow the flushing guide and enjoy your unit.

Filters & Care
Filter Structure & Life
The N5 Bard uses 3 independent filters. When one reaches end of life, replace only that one — no need to change the whole set. ANC smart monitoring calculates filter life based on usage, water quality, and time, showing remaining life on screen.
| Filter | Replacement | Function |
|---|---|---|
| Stage 1 MC121 (Gold) | ~6-8 months | Pre-filter: removes sediment, rust, impurities; adsorbs chlorine, color, odor |
| Stage 2 R107 (Silver) | ~2 years | APQ1.0/RO membrane: blocks heavy metals, bacteria, pesticides, organics |
| Stage 3 QC113 (Gold) | ~6-8 months | Activated carbon zinc-alkaline: mineralizes zinc, improves taste, inhibits bacteria |
The bundle version includes 3 extra Stage 1 & 3 extra Stage 3 filters for 2-3 years of use, at as low as ¥0.46/day.
Filter Replacement Steps
1. When the screen alerts (filter light turns red with beep), prepare the matching new filter.
2. Open the top cover, locate the filter to replace.
3. Rotate from "Lock" to "Unlock" and pull out the old filter.
4. Remove packaging, insert the new filter, rotate from "Unlock" to "Lock."
5. The corresponding indicator returns to normal. Done.
After replacing, flush 3 times with cold water (as in the new-unit flushing guide) to fully soak the new filter. No service technician needed — replace it yourself.
Filter Light Colors
| Blue/White light | Filter life sufficient |
| Green light | ~1/3 consumed |
| Red light | ~1/3 life remaining |
| Red flashing + beep | End of life, replace within one week |
Regular Cleaning
Raw Tank (7L): Tool-free quick-release. Clean every 1-2 weeks. Remove, rinse with clean water, wipe with soft cloth. Do not use hard brushes that may scratch the tank.
Pure Tank (2L built-in): Clean every 1-2 months. Open the lid, rinse with water, wipe with soft cloth. The Helix UV lamp cycles automatically for long-term antibacterial effect.
Body: Wipe with a soft dry cloth. Do not use corrosive cleaners or rough rags. Avoid direct sunlight.
Waste Water
The settling float magnetic structure stabilizes waste ratio at ~3:1, meeting Grade-1 water efficiency. The remaining water in the raw tank is not truly "waste" — it flushes impurities off the filter surface to protect filter life. When prompted to change raw water, drain the old water and refill with fresh tap water. Waste water is not drinkable but can be reused for watering plants, mopping, or flushing toilets.
Cleaning & Descaling
Daily cleaning: Raw tank — rinse every 1-2 weeks. Pure tank — clean every 1-2 months. Body — soft dry or slightly damp cloth only.
Pipe descaling: If local water is hard, descale every 3-6 months: Use a container larger than 250mL, add food-grade citric acid, dissolve with ~200mL of 98℃ hot water from the unit, pour into the raw tank. Run a circulation flush for ~30 minutes. Drain, then refill with tap water and drain 2-3 times. Use only food-grade citric acid — never strong acids or chemicals.
Long-term idle: If unused for over 72 hours, first drain all internal water, refill the raw tank, wait for the pure tank to fill, then drain again. Repeat 3 times before normal use.
FAQ
The N5 Bard produces mineralized zinc alkaline water at around pH7.6. Zinc is an essential trace element linked to normal appetite, immunity, growth, and cognitive development. Composite ion softening gradually optimizes water quality for a sweet, smooth taste. Suitable for all ages: children benefit from zinc for development, office workers maintain appetite, the elderly get pH-balanced hydration, and tea enthusiasts get fuller tea extraction.
White foam is normal — it consists of tiny bubbles that dissipate when left standing. Safe to drink. Two causes: (1) purification pressurizes air into water, which releases as bubbles when pressure drops at the spout; (2) temperature changes alter air solubility.
This product uses many food-grade plastic parts, so a slight plastic smell initially is normal. All plastic parts undergo ultrasonic cleaning before shipping. Simply follow the new-unit flushing process and the smell will disappear. After flushing, the water tastes naturally sweet.
Adjust temperature and volume to your preferred settings, then press the custom key to save. After that, press custom key + dispense to get your habitual settings in one touch. To change, re-set and the old profile is overwritten.
Long-press the volume key for 5 seconds to turn off the screen and enter eco mode. Touch any key to wake it. In addition to auto screen-off, the N5 Bard adds manual screen-off for extra power saving.
(1) Tank upgrade: N5 Baron (R508B) has a 5L tank; N5 Bard (R508L) has 7L, reducing refill frequency. (2) Capacity: Baron suits 4-5 people; Bard suits 5-6. (3) Sterilization: Baron uses 1st-gen Helix; Bard uses 2nd-gen at 99.99%. (4) Water path: Bard adds Flux integrated path for smoother flow. (5) Noise: Bard is 15% quieter than Baron.
Do not just add water. The remaining water is waste water. RO/APQ units always produce waste (3:1 ratio), which flushes impurities off the filter surface and protects filter life. If you don't drain it, impurity concentration keeps rising and may clog the filter. Waste water can be reused for watering plants, mopping, or flushing toilets.
New filters and pump contain trapped air; the pump compressing air makes noise during initial purification. Repeated purging and flushing soaks the water lines, after which noise gradually decreases. Follow the new-unit flushing steps. If still noisy, place the unit on a level surface or add a soft mat to reduce vibration.
The unit comes with one Stage 1/2/3 filter. Stages 1 and 3 should be replaced every 6-8 months; Stage 2 (RO) every 2-3 years. Actual life depends on power-on time, local TDS, and water usage. The panel shows smart replacement reminders — just replace with Bewinch original filters as prompted.
After end of life, filtration weakens as the membrane becomes saturated with impurities. Purification capacity drops and bacteria/impurities may enter drinking water, causing secondary contamination. A completely clogged filter can also overload the pump or burst pipes. Replace as prompted.
N-series units enjoy 4-year warranty: first 2 years are replacement-only (quality issues get a brand-new unit), years 3-4 are nationwide repair coverage (free labor). For product questions, contact the store where you purchased.
Bewinch offers free first-time on-site installation (including fittings and drilling, except natural marble countertops). Book via the Bewinch official mini-program or contact the store where you purchased. N9 series orders also include a free new-unit flushing visit.
Press the "Help" key on screen, then select "H2" from the menu. Align the hydrogen module/cup with the outlet and press until you hear a click. Hydrogen mode does not work when the pure tank is empty. The hydrogen electrode has a service life; contact support when degradation is noticeable.
Hydrogen molecules are unstable; drink soon after dispensing for best concentration. N9Max uses high-pressure hydrogen-locking technology that retains 60%+ after 1 hour at room temperature and stays stable even in hot water. Other models: drink immediately.
N9Max features 4th-gen platinum mixed hydrogen electrolysis and high-pressure hydrogen-locking technology, producing 700% more hydrogen than the base model and retaining hydrogen even in hot water — solving the problem of regular hydrogen machines losing hydrogen in hot water.
Based on the heat capacity formula Q=cmΔt, higher target temperature means greater temperature difference and more energy needed. With limited power, the unit reduces flow rate to reach the target temperature — higher temperature, lower flow. This follows physics and is normal.
To avoid secondary contamination, the unit uses a sealed structure. Heating water to 100℃ creates steam and excessive pressure. Although the heater has an automatic pressure relief valve, venting steam and refilling slows heating. Countertop purifiers typically heat to above 90℃ but below 100℃. The water meets direct-drinking standards even without boiling.
The unit measures water temperature right after heating; by the time it reaches your cup, ambient temperature affects it. The thermostat adjusts automatically. Manual recalibration: (1) dispense 98℃ water for 1-2 minutes; (2) dispense 85℃ for 1-2 minutes; (3) continue dispensing hot water until switching to 45℃ for 1-2 minutes. This helps the unit adapt to room temperature.
When no temperature is selected, the screen shows the real-time ambient water temperature, which changes with room temperature. The sensor is sensitive; when room temperature is at a boundary (e.g. 27-28℃), the display may flip between two degrees. This is normal and does not affect use.
Due to internal water line design, fixed-volume dispensing may have ±10mL tolerance because water lines retain a small amount. Hot water has slightly more deviation because flow slows at high temperature. Use a precisely marked measuring cup for accuracy.
(1) Open the top cover. (2) Hold the filter handle, rotate the dial from "Lock" to "Unlock," and lift out the old filter. (3) Insert the new filter aligned with "Unlock," rotate to "Lock." After replacement, long-press "Dispense/Stop" for 5 seconds to drain; repeat 2-3 times. N-series uses Spin ID/chip auto-reset — the light returns to full after insertion.
Three factors: (1) Power-on time (like food expiry — it counts even if unused once water flows through); (2) Raw water TDS (dirtier water = shorter life); (3) Total dispensed volume (more use = shorter life). The indicator is a recommendation, not mandatory — but don't wait until completely clogged, which can overload the pump or burst pipes.
Yes, 5 years. Keep unopened filters in a cool place. No need to worry about stocking up.
Non-original filters may lack hygiene safety guarantees and have reduced filtration performance and seal compatibility, potentially causing water quality issues and reducing machine life. Non-official filters cannot be reset — the unit won't work. Please buy original filters from authorized channels.
Take a cup of 65℃+ hot water, add 5-10g citric acid (adjust for severity), let dissolve and cool. Fill the raw tank with tap water, pour in the citric acid solution. Wait 30-60 minutes, wipe the interior with a clean cloth until scale comes off. Drain and rinse thoroughly.
Every 2-3 months: remove the raw tank, open the top cover and pure tank lid. Long-press "Dispense/Stop" for 5 seconds to drain (auto-stops). Wipe the interior with a clean lint-free cloth. Refill the raw tank and wait for automatic purification. Drain again 2-3 times.
Airborne algae spores enter the water and grow in well-lit areas. Move the unit away from direct light, clean the tank promptly, and soak the interior with citric acid solution.
That's not air leaking — it's the normal filter self-flush. After each purification cycle, the unit runs a ~15-second vortex flush to wash ion impurities off the membrane, protecting filter life and water quality. It happens automatically every time.
(1) Scan the Bewinch mini-program QR code, select "Installation/Repair" and submit. (2) Contact the store where you purchased. Have the machine SN code (QR code) ready when reporting.
Immediately close the inlet valve (plumbed models), stop water supply, then cut power. Contact official support promptly. Never disassemble the unit yourself.
