PROTECT YOUR AIR

This product is a multifunctional 9 in one air quality monitor with big digital LCD screen display, rechargeable Lithium-Ion battery, coming with Type-C charge cable.

It combines numerous different types of high-quality air sensors, real-time monitoring of carbon dioxide, formaldehyde(HCHO), total volatile organic compounds(TVOC), particulate matter(PM2.5/10), air quality index(AQI) indication, temperature, and humidity with clock. It is easy to operate, quality assurance worth buying.

HOW TO USE

Step 1: Long press Power Button to turn on the monitor.

Note : If your monitor does not turn on, please plug in and charge it for a while first.

Step 2: When the air quality monitor is turned on, it will proceed through its warm-up sequence for about 3 minutes to allow sensors to preheat and fan to draw in fresh ambient air.

Note : This is necessary for accurate results. The HCHO has 200-second warm-up countdown time, which is shown in the HCHO value display area.

Step 3: The monitor with CO2(Carbon Dioxide) alarm function. See step-by-step details instructions on the next page.

Note : When you keep the CO2 alarm on, if the set alarm threshold is exceeded, the monitor will alarm with short beeps. And please be aware that the CO2 alarm will also automatically stop beeping when the CO2 value is decreasing while still above the specified threshold.

Step 4: Enjoy the added benefits of having a good air quality monitor in your home!

CO2 ALARM

The default CO2 alarm sound is OPEN. CO2 alarm value is 1000ppm. Double-press Left Button to turn on/off CO2 alarm sound.

CO2 CALIBRATION

In the power-on state, put the device in the outdoors or a place with good air.

Long-press Right Button for 8 seconds, and the CO2 value will flash when you hear a beep sound.

At this state, CO2 value flashes will stop automatically and finish calibration after flashing lasts for 5 minutes. Do not touch any buttons during calibration.

HCHO CALIBRATION

In the power-on state, put the device in the outdoors or a place with good air.

After 5-10 minutes, long press Left Button for 3 seconds will emit a beep sound and the HCHO/TVOC value will reset to zero.

TEMPERATURE UNIT

The default temperature unit is Fahrenheit(°F).

Double-press Right Button to switch between Celcius(°C) and Fahrenheit(°F).

TIME SETTING

In the power-on state, double-press Power Button to enter the time setting mode.

Single-press Left / Right Buttons to set the hour, then Single-press Power Button to enter the minute setting.

Single-press Left / Right Buttons to set the minute.

After setting well, single-press Power Button to confirm.

CHARGING

When low battery icon is displayed, the device needs to be charged. Insert the included or another compatible Type-C charging cable into the device. Attach the other end to a USB DC charger (such as a smartphone charger) that outputs DC 5V at >=1000mA. Fully charge for at least 2-3 hours before use. Avoid charging with a USB computer port which only outputs 500mA.

Tips

Tip 1: Strange Readings? Do This:

1. Turn the device off for some time and then turn it on back on again (effectively allowing the monitor to reset).
   After continuous use for extended periods, the device may simply need to be reset.
2. Open a window or bring the device outdoors to allow the sensor to exhaust any accumulated fumes and to allow the readings to adjust back down to more normal levels.

Tip 2: Not Using It? Turn It Off:

For the most consistently accurate readings and longest product life, it is recommended to turn the monitor off while it is not in use. This will preserve the battery, sensor, and fan.

Tip 3: Open a Window:

Often the quickest and most practical way to get readings back into the desired range is to simply open a window to ventilate more clean outdoor air into your home. This obviously does not apply if you are located in a Wildfire area or any other area with compromised outdoor air quality.

Tip 4: Cooking Impacts Air Quality:

Cooking often releases increased amounts of unhealthy pollutants into the air including but not limited to CO2, PM2.5 and 10, and VOCs. Furthermore, how and what you cook determines the types of pollutants which will be released into the air.

CONSIDERATIONS & PRECAUTIONS

- Sampling Frequency:

The sampling frequency of the monitor is 1.5 seconds.

This means that your monitor is providing you with updated readings every 1-2 seconds. Please note that, in order to provide constantly-updated, real-time readings, it contains a continuously running mini fan which gives off a very slight buzzing sound.

• Upon turning off the monitor, you will see a brief “Power Off” appear on the screen. This is normal. This is not an error message.
• This air monitor is meant to be used indoors and kept dry at all times. It is strongly recommended to store in a cool, dry place.
• DO NOT expose to sunlight or use in an extremely polluted, dusty, or smoky environment for prolonged periods as doing so may damage the sensors over time.
  • DO NOT cover the air intake areas during use to avoid inaccurate measurements.
• DO NOT use chemicals or solvents to clean the product as residual fumes will skew air quality readings.
• DO NOT put water or other liquids on or near the product to avoid electrical damage.
  • DO NOT allow unauthorized modification or repair of this product.
  • DO NOT take apart or disassemble this monitor. Doing so may damage the product and will invalidate the warranty.
