QP Lite Air Quality Monitor

The air you breathe into your body has a huge impact on your health. The QP Lite allows you to 24/7 monitor the air in your home so you never breathe dangerous air again.

4-in-1 Comprehensive Monitoring

The QP Lite air quality monitor gives you a comprehensive look into the air you are breathing. The monitor tracks all of the most important metrics in your air to keep you safe (PM2.5/PM10, CO2, Temperature and Humidity).

Sleek, Minimalist Design

Designed to look great with any interior.

Monitor Your Air From Anywhere

By connecting to the Qingping+ App, you can monitor your air from anywhere. Get instant alerts to your phone when air quality becomes unsafe. App available on the Apple and Google Play store.

Record and View Historical Data

Track and analyse your air quality over time. Export data to a computer for further analysis.

Measure Air Quality Wherever You Go

The QP Lite is portable and lightweight with a 7+ hour battery life. This makes it the perfect device to measure air quality on the go.

OLED Display

Simple, no-nonsense display for optimal viewing.

Innovative Design

Incredibly responsive and accurate. Innovative vent design for more accurate sensors. Precision remains with long-term use.

Only Standalone Monitors Accurately Measure Air Quality

Built-in sensors on devices such as air purifiers can only detect the air conditions next to the device. QP independent air monitors can test the air anywhere.

Treat Your Body Right

High CO2 levels are common and often go unnoticed causing a variety of issues. The QP Lite will allow you to 24/7 monitor and crack a window open if concentrations get high.

Track PM2.5, One of Biggest Killers in the World

Are your PM2.5 levels over the WHO limit of 5 micrograms? If so, studies show reducing your PM2.5 levels even just a little bit with HEPA air purifiers can reduce your risk of death significantly. 

  • PM2.5: One of the biggest killers in the world, with 99% of the population breathing dangerous levels. Even moderate levels are shown to cause cancer and heart disease.

  • PM10: Similar to PM2.5, PM10 has been shown to significantly increase the risk of many fatal diseases. 

  • CO2: High CO2 levels can result in drowsiness, headaches, high blood pressure, and more.

*If levels are high, a combination of HEPA air purifiers and improved ventilation can help lower levels

The QP Lite FAQs

Does the QP Lite come with a warranty?
We offer a 1-year warranty but this product must not be used in dusty or very humid environments. Under normal living conditions, there is no problem of accuracy reduction within 3 years, which is not a warranty promise but only an estimation.
How long does it support to view the history data? Does it support historical record export?
Hourly data in the past 24 hours, the highest and lowest readings of each day in the past 7 days is available for viewing.
Do I have to be connected to the Internet to use the monitor?
No, the air monitoring function works well without an internet connection.
What smart home platforms are supported?
  • Xiaomi Mijia
  • Apple HomeKit
How long is the battery life?
The monitor can stand by for about 6.5 hours from fully charged to automatically shut down. It is recommended to keep the monitor connected to the power supply. The QP Lite has a built-in power management function similar to that of a laptop, which does not damage the battery.
Why can’t I connect to the Wi-Fi?
The QP Air Monitors won’t support Wi-Fi that requires authentication to be completed on a web page or information to be entered in a special login client. Please check the network signal before purchasing as the monitor currently only supports 2.4GHz or 2.4GHz/5GHz networks. It will not work on a 5GHz network.
What sensors are used?
The QP Air Monitors use the following sensors:
    • Grandway sensor – Built-in laser scattering PM2.5 sensor with high precision
    • Built-in Swiss Sensirion sensor for temperature and humidity, with high precision
    • Built-in SGP30 gas sensor by Sensirion for measuring tVOC. Multi-pixel technology, good accuracy and high consistency with unparalleled siloxane resistance, long-term stability and low drift
    • Built-in SenseAir CO2 Sensor S8 – Nondispersive infrared (NDIR) spectrum analysis from the world’s largest manufacturer of CO2 sensors. High stability, consistency, precision, excellent anti-interference and sensitivity.
What is the measuring accuracy??

Due to the wide variation in user environments and testing methods, we cannot guarantee accuracy, however the accuracy range of our internal tests is as follows:

  • Temperature: ±8℃ (the device needs to be turned on and placed in a windless environment for 30 min during the test)
  • Humidity: ±8% (the device needs to be turned on and placed in a windless environment for 30 min during the test)
  • 5: ±10μg/m³ when the reading is less than 100μg/m³; ±10% when the reading is greater than 100μg/m³ (the laser type PM2.5 sensor is susceptible to ultrasonic type humidifier, and it is recommended to turn off the humidifier for more accurate results)
  • tVOC: ±20% (the tVOC sensor requires complete initialisation – see FAQ on initialisation)
  • CO2: ±15% (CO2 in the air is not uniformly distributed so challenging for low cost sensors to be more accurate)
Does it come with a plug?
No. To keep costs down, we only provide the ubiquitous 5V USB power cable to power it. Plug this into your laptop or a USB plug to charge.

    I love this monitor! It has a great design and is user-friendly. It has been eye-opening to see the CO2 levels in different spaces, as well as the particulate matter readings (who knew?!). I have recently used it while travelling (train, plane) and it is light and easy to carry. The monitor needs to be plugged in to function, so while travelling I kept it plugged in to a power bank. At home or in the classroom it can plug in to a laptop or other USB socket. I bought the travel filter and air quality monitor bundle; they arrived very quickly and the set-up was easy. Definitely recommend.
