Eight Core Selling Points

Core Technology Details

Horizontal No-Install Design: As Bewinch's first horizontal no-install model, the G3Pro uses a side-mounted tank to optimize body depth to just 26cm, fitting narrow sideboards and countertops. The 5L large side tank lifts with one hand for an ergonomic water change that greatly reduces bending, so even the elderly can change water easily.

RO Reverse Osmosis + Natural Mineral Filter Media: It uses a Japan Toray RO membrane with filtration precision up to 0.0001 micron, removing 98%+ of heavy metals and impurities. Five-stage precision filtration: melt-blended polypropylene traps sediment and rust → front coconut-shell carbon adsorbs color, odor and residual chlorine → RO membrane filters bacteria, heavy metals and scale → rear coconut-shell carbon suppresses microbes and improves taste → natural mineral media releases beneficial minerals. Purify first, then mineralize, producing sweet mineral water safe to drink directly at room temperature.

Tritan Space-Grade Sterilizing Pitcher: An external, removable all-in-one sterilizing pitcher made of food-grade, crystal-clear Tritan (the same material used in maternal/infant products), BPA-free, heat-resistant to 110℃ and 3x more drop-resistant. The upgraded Helix self-circulating UV sterilization reaches 99.9%, self-starting for long-lasting bacteriostasis and solving the bacteria growth that plagues removable pitchers left unused. The 1L removable design also works conveniently for soup and porridge. Two pitchers are included for everyday use; chill one in the fridge for lemon water, fruit tea or iced coffee.

G-Radar Smart Night Light: Microcomputer sensing. In standby (when the screen dims), placing a cup under the spout automatically lights up the screen interaction area and the raw-tank lighting — easy water dispensing in the dark at night. It also adds a water-change reminder light.

Spin-Flow Instant Heating: Uses Bewinch spin-flow instant heating for more efficient heating, raising water from ambient to 98℃ in just 3 seconds — fresh water, boiled on demand. 7 temperature presets: ambient, 45℃, 55℃, 65℃, 75℃, 85℃, 98℃, covering formula, tea and coffee.

Heating performance is affected by altitude; above 1,800m the unit may not reach the set temperature.

Smart Real-Time Water Quality Monitoring: Raw and purified water TDS values are displayed, so water quality is visible. Temperature, volume, tanks and filter life are all shown on the LED touch screen — easy for everyone.

Note on purified-water TDS: outside a sterile lab, the TDS of water in a container can be affected by bacteria, water temperature and air pressure, so some deviation is normal.

Scenario Applications

Flexible pragmatism: Renters — no install, take it when you move; 26cm narrow depth fits any sideboard. Sideboard setups — side tank means less bending; one machine replaces the filter pitcher, kettle and thermal carafe. Maternal/infant — food-grade Tritan pitcher, 45℃ formula, multi-channel physical bacteriostasis for safe direct drinking.

Creative uses for your purifier: Kitchen water — rice, soup, washing fruit; better water makes better-tasting meals. Humidifier — unsafe water in a humidifier can cause lung issues, so purified water is safer. Coffee machine — coffee machines have no purification or sterilization; don't leave bottled purified water standing long. Pet water — pets have sensitive stomachs, so clean water matters; give them warm water in winter. DIY drinks — formula for the kids, tea for dad, coffee for yourself, lemon or passion-fruit drinks for daily vitamin C.

Accessories & Expansion

The G3Pro is a countertop no-install purifier with no external water-line expansion modules; everyday needs are mainly filters and cleaning supplies.

Buy original filters and accessories only from the Bewinch official store, official mini-program, or the 1,300+ nationwide service centers. Non-original filters may carry hygiene and sealing risks and affect water quality and unit life.

Core Parameters

Filter Information

Filter life is not fixed; it depends on your local water quality, water usage, inlet pressure, inlet temperature and power-on time. The panel shows smart replacement reminders.

Energy & Environment

Daily power use depends on dispensing frequency and hot-water share; instant heating only works during dispensing, saving energy vs. a thermal carafe that reheats repeatedly.

Unboxing & Package Contents

After receiving the unit, check the following list against your accessories and inspect the exterior for shipping damage.

Unboxing check: ① confirm all listed accessories are present; ② check body, tanks and pitcher for scratches or dents; ③ peel off protective film on body and filters; ④ if anything is missing or damaged, contact the store where you purchased.

Placement & Installation

The G3Pro is a no-install countertop unit — no inlet or drain connection needed. Just add tap water. The placement must meet these requirements:

Placement requirements:
1. Choose a well-ventilated, level and stable surface, away from direct sunlight and heat sources.
2. Leave ventilation space around the unit and a gap from the wall at the back.
3. The surface must support the unit (gross weight ~7.7kg); avoid uneven or wobbly surfaces.
4. A properly rated 3-prong outlet within the 1.5m cord reach.
5. The raw tank is on the side; leave one-hand clearance to slide it out.

Before first power-on:
1. Confirm the raw tank and pitcher are correctly seated.
2. Confirm filters are screwed in firmly.
3. Fill the raw tank with municipal tap water (5℃-35℃).
4. Confirm the power voltage matches the rating plate, then power on and follow the flushing guide below.

New Unit Flushing Guide

Before first use, flush the unit to activate filters and clean pipes. A new unit and filters may carry a slight odor — be sure to complete the flushing. The more you flush, the better the water taste.

Step 1: Air Out. Unbox the unit; remove the raw tank, pitcher, pitcher lid and top cover. Air out in a cool, ventilated, dry place for 8-12 hours (adjust for actual odor).

Step 2: Power On & Purify. Put the pitcher back, fill the raw tank with tap water and replace it. Power on; the water-drop purification icon appears. Wait ~10 minutes until the purified-water light goes off. The first cycle fills empty filters and pipes, so it uses a lot of raw water.

If a water-change prompt appears during purification, pour out the remaining waste water, refill, and let it continue.

Step 3: Drain Cold Water (repeat 3 times). Remove the full pitcher, empty the purified water, reinsert it; the unit purifies again. When done, repeat — emptying the pitcher 3 times in total.

Step 4: Flush with 45℃ Water (repeat 1-2 times). After purification, place a heat-resistant container (3.5L+) under the spout, tap the 45℃ icon, press "Dispense/Stop"; the red dispense light comes on; wait for it to stop automatically.

Step 5: Flush with 98℃ Water (repeat 1-2 times). After purification, tap the 98℃ icon, press "Dispense/Stop"; wait for automatic stop. Beware of hot water splashing.

Step 6: Done. After these steps the unit is ready. For the first 3 days, run one drain cycle daily to fully activate the filters.

Use at High Altitude

Boiling point note: At high altitude, lower air pressure means water boils below 100℃. Heating is affected by altitude; above 1,800m the unit may not reach the set temperature. Please consider this before ordering.

Dispensing Water

Ambient water: Press "Dispense/Stop" directly; the spout lights blue and ambient water flows. Press again to stop.

Warm / hot water:
1. Tap the temperature key to choose (ambient ~ 98℃, 7 levels).
2. Tap the volume key to choose (60~500mL, 6 levels).
3. Press "Dispense/Stop"; the red light comes on and water flows.
4. It stops automatically at the set volume; press again during dispensing to stop manually.

Temperature Presets & Scenarios

The G3Pro offers 7 levels from ambient to 98℃ with 3-second spin-flow instant heat. Recommended uses:

Volume supports 60/90/120/200/300/500mL fixed levels with auto stop, suiting bottles, cups and sport bottles. Above 1,800m altitude, low pressure may prevent reaching the set temperature.

Smart Features

G-Radar Smart Night Light: In standby (screen dimmed), placing a cup under the spout automatically lights the screen interaction area and raw-tank lighting — easy dispensing in the dark.

Smart Child Lock: Long-press the "60mL" volume icon for 5 seconds; release after the beep to toggle child-lock mode. When on, the child-lock icon lights and the raw-water TDS shows "LOC"; no dispensing can occur, preventing accidental burns or spills from children and pets. Child lock is off by default on a new unit or after a power reset.

Smart Screen-Off Eco: Auto screen-off when idle; ~1 kWh per 500 standby hours. Tap any key to wake the screen to full brightness.

Real-Time Water Quality: Raw and purified TDS values are displayed, so water quality is visible. Temperature, volume, tanks and filter life are all clear at a glance.

Side Tank Design

5L side tank: The innovative side-tank design is ergonomic, greatly reducing bending during water changes — even the elderly can change water easily. The 5L large capacity means continuous drinking, enough for 3-4 people for a day.

Filter Structure & Life

The G3Pro uses three independent filters — replace whichever one reaches the end of its life instead of replacing the whole set. The screen shows remaining filter life in real time and reminds you when due.

Actual filter life depends on power-on time after activation, local water quality and dispensed volume; follow the screen indicator.

Replacing Filters

Spin ID sensor reset. When a filter's life shows blank flashing with beeps, it needs replacing. Using filter #1 as an example:

1. With the unit not purifying, cut the power and unplug.
2. Remove the top cover and find the old filter to replace.
3. Follow the mark, turn from "locked" to "unlocked" and pull out the old filter; within 30s the screen shows L1 (L2 for filter #2, L3 for #3) and beeps.
4. Insert the new filter and turn from "unlocked" to "locked"; L1 disappears with a beep and the bar fills — replacement complete.
5. Drain 2-3 times after replacement before normal use.

No home visit needed; you can replace filters yourself. If the filter indicator does not change within 30s after screwing in, pull it out and reinsert, repeating until it auto-resets.

Notes:
1. Do not turn a filter during chip recognition, or you may damage the chip or interrupt sensing and fail the reset.
2. Each filter chip can reset only its own filter once; only replace when the life system prompts you.
3. After installing a new filter, follow the new-unit flushing method and empty the pitcher three times to fully soak it.

Use only Bewinch original filters; non-original parts may cause substandard water quality or unit failure.

Daily Cleaning & Care

Raw water tank: The 5L side tank is quick-release; clean every 1-2 weeks. Remove it, rinse the interior with clean water, wipe with a soft cloth, and avoid hard brushes that scratch. Reinstall after cleaning.

Purified tank (sterilizing pitcher): The 1L removable pitcher is pull-out, food-grade Tritan, dishwasher-safe. Clean it regularly. Remove and rinse with clean water, wiping the interior with a soft cloth. The bottom Helix UV lamp cycles automatically for long-lasting bacteriostasis.

Body: Wipe with a soft dry cloth; avoid corrosive cleaners or hard cloths. Keep the unit away from direct sunlight.

Waste Water

Ratio & handling: The remaining water in the raw tank is not really "waste" — it flushes impurities off the filter and helps maintain filter life. When the unit prompts a water change, pour out the waste, refill with fresh water, and continue. Not for drinking, but the waste water can be reused for cleaning or watering, so nothing is wasted.

Cleaning & Descaling

Daily cleaning: Body — wipe with a soft dry or slightly damp cloth; no corrosive cleaners, steel wool or hard brushes; never immerse or hose the whole unit. Raw tank — remove every 1-2 weeks, rinse and wipe. Pitcher — the 1L removable Tritan pitcher is dishwasher-safe; the bottom Helix UV lamp cycles automatically. Spout — wipe the drip tray and spout with a soft cloth and keep dry.

Descaling (H05 self-clean mode): Over time the RO membrane clogs with calcium/magnesium and purification slows. Run a self-clean/descale cycle every 3-6 months depending on local water quality; it takes about 1 hour:

1. Make descaler: in a 250mL+ container, add citric acid descaler, run ~200mL of 98℃ hot water and stir until fully dissolved.
2. Enter mode: long-press the volume key ~10s; after the second beep the raw-water TDS shows "H05" to start self-cleaning.
3. When the screen shows "01", remove the raw tank, long-press "Dispense/Stop" 5s to drain (shows "02"); once empty, fill the raw tank with tap water to the max line and pour in the citric-acid water.
4. When draining shows "03", replace the raw tank; "04" starts auto pipe flushing for ~30 minutes.
5. When "05" appears, remove the raw tank, pour out the dirty water, refill and replace; after "End", it exits automatically after 5s.
6. After exit, long-press "Dispense/Stop" to drain 2-3 times before normal use.

If you enter "H05" by mistake, long-press the volume key ~10s until "End" appears to exit manually.
