Dear Customer,
Congratulations on your choice of choosing a quality air purifier from NIPPO. Please read the instructions thoroughly before using this product.
Safety Precautions:
- Use only the power adapter supplied with this product. Do not plug in or unplug with wet hands, and do not pull on the cord to unplug. If the adapter or cord is damaged, replace it only with a genuine part from Nippo Customer Care.
- Check that your mains supply matches the voltage marked on the product before connecting it. Make sure the socket makes firm contact — a loose socket can cause the plug to overheat.
- Always switch off and unplug the unit before cleaning, maintenance, or moving it. Never move the unit by pulling or tugging the power cord.
- Keep the unit away from water and other liquids. Do not insert fingers or foreign objects into the air inlet or outlet, and do not pour liquids or throw powders into the air outlet.
- Keep open flames (candles, incense, cigarettes) and flammable sprays away from the unit. Do not wipe the unit with benzine, thinner, or alcohol. Do not use in hot, humid, or damp places such as bathrooms.
- Do not operate the unit while using indoor aerosol insect repellents, or in places heavy with oil contamination, flammable gas, or chemical smoke.
- This unit contains an enclosed UV-C source. Never operate with covers open or attempt to view the UV-C LED directly.
- Do not burn a used filter or put it to any other use. Combustion of the filter may cause irreversible damage or endanger life.
- Children aged 8 years and above, and persons with reduced capabilities, may use this appliance only with supervision or instruction on safe use. Children shall not play with the appliance, or clean and maintain it without supervision.
- When using with gas-fuelled appliances, ventilate sufficiently to avoid carbon monoxide poisoning. This product cannot eliminate carbon monoxide.
Important Notes:
- Remove the filter packaging bag completely before first use. Running the unit with the packaging fitted will damage the motor and void the warranty.
- Make sure the outlet grille and the bottom filter cover are correctly installed before powering the unit on.
- Do not place any object on top of the unit, and do not block the air inlet or outlet.
- Do not place the unit directly beneath an air conditioner — condensate dripping into the unit will damage it.
- This product is designed for indoor household use only. Always check the "Troubleshooting" section of this manual before calling for service.
Before Use:
Unpack your air purifier carefully and verify all parts are present in the package before starting.

Product Overview:
The L301s in exploded view. The composite filter is reached through the bottom cover; the air outlet and display sit on top of the unit.
Preparation Before First Use:
- Turn the unit over and rotate the bottom cover in the direction indicated to open it.
- Remove the filter and take it out of its packaging bag completely.
- Place the filter back into the unit and lock the bottom cover.
Positioning the Unit:
- Stand the unit upright on a firm, flat, horizontal surface.
- Leave at least 10 cm of clear space between the unit and walls or other objects, so that air can circulate and the particle sensor reads accurately.
- Keep out of direct sunlight and away from heat sources and damp locations, and do not place the unit directly beneath an air conditioner. For a better purifying effect, keep doors and windows closed when using the unit.
The body of the unit — the particle sensor window with the power inlet beside it.
Getting Started:
- Connect the power adapter to the power inlet on the side of the unit — the small round socket beside the particle sensor — and plug it into the mains. The unit beeps, all indicators light for about one second, and it enters standby.
- Touch the Power button to begin purifying. The unit always starts at Speed 1; touch the Wind Speed button to change the airflow setting.
- The sensor reads the room for about 30 seconds; the air quality ring then shows the colour for the current PM2.5 level.
Top of the unit — the display sits at the centre of the outlet grille, with the touch controls on the front rim.
Control Functions:
In standby, touch any button to wake the display, then touch Power to begin purifying. Touch again to stop the unit and return to standby.
Touch to cycle the airflow setting — Speed 1 → Speed 2 → Sleep → Auto.
Touch to cycle the sleep timer — 2H → 4H → 8H → Timer off. When the timer finishes, the unit shuts down and returns to standby.
Cycles the sterilisation functions — UV-C → Negative ion → both on → off. The icon flashes for about 5 seconds; if no further touch is made, the unit runs with the function shown. Each runs for two hours, switches off automatically, and can be started again two hours later.
Resets the Wi-Fi settings and puts the unit into pairing mode for the Nippo Airvue app. The buzzer sounds once and the Wi-Fi indicator flashes.
Turned on from the Nippo Airvue app for maximum purification. Touching the Wind Speed button on the unit turns Turbo off and returns to Speed 1.
Resets the filter life counter. To reset before the filter icon flashes, use the same gesture within 30 seconds of powering on.
Display Icons:
In working mode the selected function glows at full brightness and others at 40%. After 10 seconds without a touch, all indicators except the selected one switch off; touching any control illuminates them again.
Operating the Air Purifier:
- Set the unit to Auto mode for everyday use — it adjusts the fan speed automatically according to the PM2.5 concentration detected by the built-in sensor.
- Use Sleep mode during sleep hours — the unit runs at its quietest setting and the display switches off.
- Use Speed 2 or Turbo (via the app) to purify quickly when air quality is poor, while cooking, or while cleaning the room.
- Use the Sleep timer to switch the unit off automatically after 2, 4, or 8 hours.
Air Quality Indicator and Notifications:
| Indication | Status | Description |
|---|---|---|
| Blue light ring | Excellent air quality | PM2.5 is low. In Auto mode the unit settles to its quietest speed. |
| Yellow light ring | Good air quality | Moderate PM2.5. In Auto mode the unit runs at medium airflow. |
| Red light ring | Poor air quality | High PM2.5. In Auto mode the unit increases airflow until air improves. |
| Filter icon flashing | Filter life expired | Replace the filter and reset the filter life counter. |
| Wi-Fi icon flashing | Ready to pair | Add the device in the Nippo Airvue app. |
| Wi-Fi icon steady | Connected | The unit is connected to your home network. |
Filter Replacement:
The composite filter is a consumable. When the filter reaches the end of its service life, the filter icon on the display flashes to indicate that the filter must be replaced. Use only genuine Nippo Airvue filters.
- Power off the unit and unplug the adapter.
- Lay the unit on its side or turn it over, and rotate the bottom cover in the direction indicated to open it.
- Remove the old filter and pack it properly for disposal.
- Unpack the new genuine Airvue filter, removing the packing material completely, and place it into the unit.
- Rotate the bottom cover to lock it, stand the unit upright on a flat surface, and reconnect the power.
The composite filter is reached through the bottom cover.
Resetting the Filter Timer:
- Touch and hold the Wind Speed and Timer buttons together for about 3 seconds. The buzzer sounds once and the filter life counter resets to zero.
- If the filter icon stays lit after a new filter has been fitted, the counter has not been reset — repeat the step above. To reset the counter before the filter icon flashes, use the same gesture within 30 seconds of powering on.
Filter Notes:
- •Remove dust from the filter's outer surface regularly. The filter cannot be rinsed, washed, or reused, and must not be cleaned with a vacuum cleaner.
- •Always unplug the adapter before removing or installing the filter.
Wi-Fi Pairing and App Control:
Download the Nippo Airvue app from the App Store or Google Play and register with your phone number or email. Scan a code below to go straight to the listing.
Adding the device
- Have the name and password of your 2.4 GHz Wi-Fi network ready. The purifier joins 2.4 GHz networks only; your phone itself may be on either 2.4 GHz or 5 GHz.

- Turn on Bluetooth on your phone, open the Nippo Airvue app, and tap "+" on the home screen to add a device. The app finds the purifier automatically while it is in pairing mode.
- Select the purifier when it appears, enter the name and password of your 2.4 GHz network, and confirm.
- When the app confirms the device has been added, pairing is complete — the Wi-Fi indicator stays steadily lit and the unit is listed in the app.
In the app
On/off, fan speed, Turbo, UV-C and negative ion, timer, filter life and real-time air quality. Once paired you can control the unit from anywhere, provided both your phone and the purifier have a network connection.

Cleaning
- Power off the unit and unplug the power adapter.

TROUBLESHOOTING:
| Problem | Cause | Solution |
|---|---|---|
| Unit not starting | Adapter not connected properly; socket switched off or tripped; grille or bottom cover not installed | Check the adapter connection at both ends and the socket. Confirm the grille and bottom cover are correctly fitted. |
| Air volume becomes smaller | Filter packaging not removed; filter clogged or at end of life; air inlet or outlet blocked | Remove the filter packaging. Replace the filter if it needs replacing. Clear any obstruction and clean dust from the air inlet. |
| Significant noise | Foreign object inside the unit; filter not seated correctly; unit on an uneven surface | Remove any foreign object and re-seat the filter. Stand the unit level on a firm floor, or select a lower wind speed. |
| Unusual smell | A slight plastic smell is normal in the first few uses; a dirty filter also causes odour | Clean or replace the filter. If a burning smell is present, unplug the unit immediately and contact Nippo Airvue Service. |
| Filter icon stays lit after a new filter | Filter life counter not reset | Hold Wind Speed + Timer for 3 seconds to reset the counter. |
| Air quality colour not updating | Sensor is calibrating; dust build-up on the sensor | Allow about 30 seconds after switch-on. Keep the sensor window free of dust. |
| Wi-Fi not connecting | Purifier being joined to a 5 GHz network; phone too far from the unit; unit not in pairing mode | Enter a 2.4 GHz network for the purifier (your phone may stay on 5 GHz). Keep the phone close, Bluetooth on, and hold Wind Speed 3 seconds to re-enter pairing mode. |
