Protect Your Air
This product is a CO2 Meter 3 in One that detects Carbon dioxide
(CO2),Temperature and Humidity. It is using Infrared (NDIR) sensor real-time
monitoring of Carbon dioxide (CO2) with temperature and humidity on its
display. If the CO2 concentration reaches 1000 PPM , the monitor will trigger
a danger alarm.

HOW TO USE
Step 1: Short press the power button to turn it on. Note : If the device does
not power on right away, then please
charge it first.Plug in the CO2 meter using a standard cell phone adapter
plug. Step 2: Double click the power button to switch temperature units
between Celsius degree and Fahrenheit degree. Step 3: Press the power button
one time to turn off the alarm. Step 4: Calibrate the CO2 monitor. a. Take the
monitor outside or in a well-ventilated area with
very high air quality. b. short press the power button 5 times,the CO2 value
starts
flashing. c.Wait 5-10 minutes for the flashing to stop. Note : When the CO2
value stops flashing, this signifies the CO2 sensor calibration is complete.
Step 5: In the power on state, press and hold the power button for 2 seconds
to turn it off.

CO2 ALARM
The CO2 monitor was designed with a built-in CO2 alarm. This CO2 alarm beeps
when the CO2 levels surpass the threshold (1000 PPM ). The purpose of the CO2
alarm is to notify you right away so the appropriate action can be taken
immediately to improve CO2 levels (i.e., by opening a window / door or
stopping the activity causing the high reading).
Note 1: The CO2 alarm’s default setting is ON. The CO2 alarm can be turned on
or off by simply pressing the power button one time. Exposure to less-than-
optimal CO2 levels for an extended period of time may not be healthy and it is
therefore recommended to keep this CO2 alarm function turned on. Below ,the
pictured alarm signal shows the CO2 alarm is turned on.
Note 2: If you have elected to keep the CO2 alarm on, please be aware that the
CO2 alarm will stop beeping automatically even when CO2 levels are still above
1000 PPM if the CO2 levels are decreasing.
TEMPERATURE ADJUSTMENT AND CHARGING
Charging: Please use any cell phone or other power adapter that outputs at
=1000mA (the output is directly stated on the adapter). Please avoid charging with a USB computer port which only outputs 500mA. It is recommended to fully charge for at least 2 – 3 hours before use for the longest battery life.

UNDERSTANDING THE METRICS
1.CARBON DIOXIDE (CO2)
Definition: Carbon Dioxide is a gas which is colorless, tasteless, and
important for plant photosynthesis.
Impact on Health: Too much CO2 may cause drowsiness, reduced cognitive
function, and poor decision making. CO2 is generally allowable up to 1,000ppm.
With readings above 2,000, it can cause dizziness, tinnitus, or even
suffocation.
Possible Causes of High Reading: Poor ventilation and recycled indoor air
(Note: A newer home
may trap and accumulate higher levels of CO2 as newer homes are constructed to
be more air tight) Cooking (especially using the oven) and use of certain
appliances Soil build-up / mold (which releases CO2)
Tips to Improve: Increase air circulation. It is imperative that a room or
building has
proper ventilation to ensure lower, healthy levels of CO2. Outdoor air
typically contains CO2 levels between 400 – 450PPM (although certain areas may
have less healthy outdoor air and be above this).
06
Add plants to your home: This helps to reduce CO2 and increase oxygen which
can have
the effect of making you feel less drowsy. Some recommended indoor plants for
improving air quality in your home are Areca Palm, Philodendron, Rubber Plant,
Peace Lily,Dracaena, Snake Plant, Boston Fern, Aloe Vera, English Ivy and
Spider Plant.
Use filters and air purifiers: To improve indoor air quality, it is highly
recommended to use not
only a standard pleated or HEPA furnace filter, but also an air purifier in
the areas in which you spend the most time; perhaps maybe your home office or
bedroom.
2.TEMPERATURE Definition: Measurement of the heat or cold of the environment.
Impact on Health: Issues with your respiratory and circulatory systems.
Tips to Improve: Temperature inside the home is typically a controllable
element. It is advised to adjust temperature slowly rather than allow drastic
changes.
07
3.HUMIDITY Definition: Humidity is the level of water vapor in the atmosphere.
Impact on Health: With an increase of humidity by 35% or more, formaldehyde
emissions will increase and remain suspended in the air. Possible Causes of
High Reading: Humid outdoor weather Activities which release steam / moisture
into the air such as
drying laundry, taking a hot bath or shower, or boiling water / liquid Tips to
Improve: Utilize dehumidifiers to control levels of humidity. It is
recommended to keep humidity in your home around 50% in the Summer and around
30% in the Winter.

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 CO2 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 CO2 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.
09
CONSIDERATIONS & PRECAUTIONS
Sampling Frequency: The sampling frequency of the CO2 monitor is 1.5 seconds.
This means that your CO2 monitor is providing you with updated readings every
1-2 seconds.
This air CO2 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.
