FAQ

    1. Unplug the air purifier before any cleaning and maintenance.
    2. Remove the filter and clean the inside of the purifier with a dust vacuum.
    3. Wipe clean the housing of the purifier with a dry, soft, non-abrasive cloth.
    4. For optimal use, the outer pre-filter can be cleaned with a soft, dry brush once every 2-4 weeks.
    5. It is recommended to clean the AQ sensor on the back with a dust vacuum at least every three months.
  • The filter life is measured by the air purifier's algorithm based on the operating mode, fan speed, run time and indoor air quality. It is recommended that the filter be cleaned every 2-4 weeks and replaced every 6-8 months or when the filter changes reminder alerts. The filter change reminder will flash when the filter needs to be replaced.

  • It consists of a PET mesh, a H13 HEPA filter (filter media), modified carbon (CTC 60), a plastic filter cover, and a sealing foam layer.

    • Pre-filter: Captures larger particles such as hair, household dust (lint, paper scraps, textile fibers), fluff, dander, and common pollen (typically 10–100 μm).
    • HEPA filter: Removes fine particles including PM2.5, smaller pollen (≤5 μm), dust mites, and smoke.
    • Activated carbon layer: Adsorbs gases and odors such as formaldehyde, benzene, TVOCs (total volatile organic compounds), and unpleasant smells through physical adsorption.
  • The Filter Change Reminder will not automatically reset. Please press and hold the Filter Reset button to reset the reminder. The indicator will turn off after resetting.

    1. Blue color means the air quality level is excellent. 0~13
    2. Green color means the air quality level is good. 10~35
    3. Orange color means the air quality level is moderate. 35~155
    4. Red color means the air quality level is poor. 155~999
    1. Pull out the aroma pad tray.
    2. Ensure the aroma pad is properly placed in the tray.
    3. Add 5–10 drops of essential oil onto the aroma pad.
    4. Note:
    • Essential oil should be added to the aroma pad only. Do not apply it to the filter or any other parts.
    • The scent may be mild; the purifier is not designed to function as an aroma diffuser.
    • The scent intensity is not adjustable.
    • Replace the aroma pad if it becomes stiff.
    1. The purifier does not come with a preset scent. Essential oil needs to be added onto the aroma pad for fragrance.
    2. Essential oils are not included. Any preferred essential oil can be selected and used based on personal preference.
    1. The aroma function is designed to provide a mild scent while the device is operating and is not intended to perform like a dedicated aroma diffuser.
    2. The strength of the fragrance may vary depending on the type and concentration of essential oil used. Some lighter oils may produce a weaker scent. Using a stronger or more concentrated essential oil may improve the fragrance experience.
  • The product is PTFE-free and is safe for use around birds and other small pets when used as directed.

  • The machine has been in a closed package after leaving the factory, and there will be some smell of packaging materials attached. It is recommended to set the device to turbo mode when using it for the first time, and run it for half an hour without a filter. Then re-install the filter to use it again.
    Note: The protective film of the filter needs to be removed before installation
  • • During the initial few days, new air purifiers produce a plastic smell, which is normal and will dissipate eventually.
    • Do not add essential oils or diffusers into the air purifier or use in an excessively humid area. Humidity will cause mold to grow.
    • If the filter has absorbed pollutants to its maximum capacity, then the smell may come from the dirty filter. Please replace the filter when necessary.
    1. Make sure the unit is used within the recommended coverage area. If the room size exceeds this range, the purification performance will be reduced.
    2. Check if the filter packaging has been removed.
    3. The overloaded filter will make the fan work harder to pass the air through. Consider replacing the filter if it is clogged.
    4. Check if the air outlet and inlet are obstructed.
    5. Make sure the windows are closed as polluted air may continue coming in from outside the windows.
    6. Do not place in crowded areas and corners.
    7. When the pollution concentration is high, it is recommended to increase the fan speed to the highest level for more effective purification.
    1. The sensor has a built-in self-calibration function. Moving the unit to a cleaner environment and running it for about 1 hour allows automatic recalibration.
    2. Regular cleaning of the sensor inlet helps prevent dust accumulation.
    3. A simple test can be performed by covering the purifier with a bag. If the PM2.5 reading changes rapidly (typically decreases), the device is functioning correctly. If the reading remains high, relocating the device to a clean environment will allow automatic recalibration. If the issue persists, customer service can arrange a replacement according to the service policy.
  • The Air Quality Sensor detects PM 2.5 particles but cannot detect odors.

    1. Air purifiers cannot completely eliminate odor; they may only reduce it slightly through airflow dilution. The purifier is more effective at removing odors in smaller spaces. In larger areas, odor removal performance may be less noticeable.
    2. For pet urine odors, using a pet-specific Dreo air purifier is recommended.
    3. To reduce odor, ventilating the room is the most effective method. Alternatively, using an air purifier with essential oils can help mask the odor.
    4. Check the filter’s lifespan. If the filter has reached the end of its service life, replace it to restore odor removal performance.
    1. The turbo mode will produce a higher noise level as the fan is at the maximum speed to clean the air in the room more quickly. Switch the air purifier to sleep mode or lower fan speeds.
    2. Make sure the air purifier is operating on a flat, stable surface.
    3. Check if the filter is placed properly or if the filter packaging has been removed.
    4. If the unusual noise still exists, there may be external objects blocking the air openings. Small objects may be removed by carefully inverting the unit. If larger objects are stuck or cannot be removed, contact customer service for guidance on disassembling the unit safely.
  • Foreign objects may have fallen into the unit, obstructing the fan wheel.

    1. Small objects may be removed by carefully inverting the unit.
    2. If larger objects are stuck or cannot be removed, contact customer service for guidance on disassembling the unit safely.
    • Place the air purifier on a flat, stable surface and plug it into a power outlet.
    • For optimal performance, keep the unit at least 15 inches (38 cm) away from walls, curtains, furniture, or other obstructions to ensure proper airflow.
    • If maintaining a 15-inch clearance is not practical, keep a minimum distance of 2 inches (5 cm) from surrounding objects.
