Air Information

Your air purifier automatically scans your air and analyzes the quality. By default, the air purifier shows the overall clean air percentage on the center of the display.

1. Tap to change the air quality information shown on the center of the display.
2.  Keep tapping to cycle through air quality readings for PM1.0, PM2.5, PM10, and overall clean air percentage. For more information, see PM Values (page 11).
3.  When you stop tapping , the current air quality reading will stay on the display until you restart the air purifier. If you restart the air purifier, the display will again show the overall clean air percentage.

Clean Air Percentage

Clean air percentage is an estimated measurement of the amount of clean air in the room, between 0% (bad) to 100% (very good).

This percentage is calculated by an algorithm, based on:

•  The concentration of particles detected in the air, including micro-particles.
•  The change in detected particles in the air during purification.

Note: The percentage is approximate. The sensor can only detect airborne particles, not odors or gasses.

PM Values

“PM” stands for “Particulate Matter,” and usually refers to airborne particles floating in your air,
including dust and most allergens. Many of these particles are too small to be seen with the naked eye, and without air purification, they stay in the air much longer than heavier or larger particles.

Your air purifier’s AirSight Plus 2.0 Laser Dust Sensor detects the amount of airborne particles that are in a given space (µg/m³). Generally, the lower the number, the better your air quality.

USING YOUR SMART AIR PURIFIER (CONT.)

When you press to show PM readings on the display, the number is the estimated amount of airborne particles (µg) that are detected per 1 cubic meter (m³) of air volume.

The PM value (1.0, 2.5, or 10) refers to particulate matter (PM) less than or equal to 1, 2.5, or 10 microns (µm) in size (measured by the diameter of the particle). For example, PM2.5 refers to particulate matter that is 2.5 microns or smaller.

Vent Angle

You can set the vents on top of the air purifier to different angles to disperse purified air
throughout your room more efficiently.

Purified air is typically dispersed in a fixed direction through the top of the air purifier. Having different vent angles is especially effective in rooms with a lot of furniture or other objects that can block airflow, as well as rooms with an unusual layout or high ceilings.

1.  By default, the vents disperse air at a fixed 75º angle.
2.  Press to rotate the vents to a different angle. The vents will cycle through 45º, 60º, 75º, and 90º angles.

Note: If the vents start at a 75º angle, press to change the vent angle to 90º. Press the button
repeatedly to rotate the vents down to 75º, 60º, and 45º.

3. lights up when the vents are rotating and turns off when the vents reach the desired angle.

Note:

•  Do not unplug the air purifier while it is running. Tap to turn off the air purifier, then unplug.
• The vents will not close if power is unexpectedly cut off.
• The angle of the vents can be adjusted to any angle between 45º–90° in the VeSync app.

Light Detection

Light Detection uses the built-in light sensor to automatically adjust air purifier settings based
on the amount of light in the room.

•  The display will automatically turn off when the room gets dark. If the air purifier is in Auto Mode, it will not use the high fan speed or Turbo Mode, even when the air quality is poor, to avoid making too much noise.
•  When the room becomes light again, the air purifier will return to its previous settings. The display will automatically turn back on, and Auto Mode will no longer be limited.

Note: Light Detection can be turned on/off in the VeSync app (see page 14)

Timer

You can set a timer for 1–12 hours.

Note: You can set a timer for 1–24 hours in the VeSync app

1.  Tap repeatedly to set a timer in 1-hour increments, beginning with 1 hour. If you don’t touch any buttons for 5 seconds, the display will switch to showing the air quality reading and the timer will start automatically.

USING YOUR SMART AIR PURIFIER (CONT.)

•  To cycle through timer options more quickly, press and hold for 2 seconds.

2. The timer will count down from your selected time.

•  You can change the fan speed at any time while the timer is on.

3. While the timer is on, you can tap to show the remaining time (rounded up to the nearest hour) for 5 seconds. Within these 5 seconds, you can tap again to add more time in 1-hour increments.

•  The timer will restart if the time is changed.
• You can see the exact remaining time in the VeSync app.

4. When the timer is finished, the air purifier will turn off.
5. To cancel a timer, tap repeatedly until the display reads “–H”.

Note: The air purifier will remember the last timer setting while turned off. When you restart the air
purifier, you’ll also need to restart the timer.

•  Captures large particles such as dust, lint, fibers, hair, and pet fur.
•  Maximizes the filter’s life by protecting it.
• Removable and washable to increase filtering efficiency (see Cleaning the Pre-Filter, page 17).

B. H13 True HEPA Filter

•  Captures at least 99.97% of airborne particles 0.3 microns (µm) in size.
•  Traps small particles such as fine dust, smoke particles, and allergens such as pollen and pet dander.

C. High-Efficiency Activated Carbon Filter

•  Physically absorbs smoke, odors, and fumes.
•  Filters compounds such as formaldehyde, benzene, ammonia, and hydrogen sulfide.
•  Reduces household odors from food, cigarettes, and pets.
•  Tested to effectively filter volatile organic compounds (VOCs).

Note: Carbon filter efficiencies decrease with use. If your air purifier isn’t as effective at filtering odors or gasses, make sure to replace the filter (see page 19).

ABOUT THE FILTER (CONT.)

Clean Air Delivery Rate

This air purifier has a Clean Air Delivery Rate of 360 cubic feet per minute (CFM), or 612 m³/h.

Clean Air Delivery Rate (CADR) measures the efficiency of an air purifier by indicating the
volume of clean air that an air purifier produces per minute. This is based on removal of dust,
pollen, and smoke, which are the 3 most common indoor air pollutants. The higher the CADR, the more particles the air purifier will remove and the larger the area it can clean. The rating is measured at the air purifier’s highest speed.

Air Change Per Hour

The air change rate is how many times all of the air in a room can be purified (or “changed”) by the air purifier in 1 hour. Air changes per hour (ACH) are calculated with the recommended room size assuming 8 ft / 2.4 m ceilings. For smaller rooms, the air change per hour will increase. This air purifier can change air 5 times per hour at the max speed in a single, closed room up to 558 ft² / 52 m². This is measured at ACH 5. The air purifier is effective for larger rooms, but air purification
will take longer, with fewer air changes per hour. For example, the air purifiers effective range is 1,395 ft² / 130 m² based on 2 ACH, or purifying the air in the room 2 times per hour.

Note: To effectively clean air, keep windows and doors closed while the air purifier is on.

Humidity

Moisture may damage the filter. This air purifier should be used in an area with a humidity level below 85% RH. If you use the air purifier in excessively humid areas, the surface of the filter may become moldy.

Note: Water or moisture will allow mold to grow. To solve a mold problem, get rid of the source of the moisture and clean up the mold.

Essential Oils

Do not add essential oils to the air purifier or filter. The filter will become damaged by the oil and will eventually release an unpleasant smell. Do not use diffusers near the air purifier.

CARE & MAINTENANCE

Cleaning the Smart Air Purifier

• Unplug before cleaning.
• Wipe the outside of the air purifier with a soft, dry cloth. If necessary, wipe the housing with a damp cloth, then immediately dry.
•  Vacuum the inside of the air purifier.
•  Do not clean with abrasive chemicals or flammable cleaning agents.

Check Filter Indicator

The Filter Button ( ) will light up as a reminder to check the filter. Depending on how often you use the air purifier, the indicator should turn on after about 12–15 months. You may not need to change your filter yet, but you should check it when lights up.

When your air purifier is set up with the VeSync app, you can also check the app to see your remaining filter life. You will also receive a notification from VeSync when it’s time to check your filter.

The VeSync app uses a scientific algorithm to determine your filter life based on air quality,
amount of use, and other factors. The filter life percentage is based on 12 hours of daily use.

•  If you’re manually typing in the SSID and password, double check that both are entered correctly.
•  Try moving your air purifier closer to the router. Your phone should be as close as possible to your air purifier.
•  Your router may need to be at a higher location, away from obstructions.
•  Make sure your air purifier and router are away from appliances (such as microwave ovens, refrigerators, electronic devices, etc.) to avoid signal interference.
• If you’re using a VPN, make sure it’s turned off while setting up your air purifier.
•  Disable portal authentication for your Wi-Fi network. If portal authentication is enabled, the air purifier will not be able to access your Wi-Fi network, and setup will fail.

Note: Portal authentication means that you need to sign in to your Wi-Fi network through a web page before you can use the Internet.

My air purifier is offline.

• Make sure the air purifier is plugged in and has power, then refresh the VeSync menu by swiping down on the screen.
•  Make sure your router is connected to the internet and your phone’s network connection is working.
• Delete the offline air purifier from the VeSync app. Swipe left (iOS®) or press and hold (Android™), then tap Delete. Reconfigure the air purifier with the VeSync app.
  Note: Power outages, internet outages, or changing Wi-Fi routers may cause the air purifier to go offline.
  If your problem is not listed, please contact Customer Support (see page 23).
