So probably the other readings are not very accurate either. But I mainly got it for the CO2, and it's probably roughly right. It's fun to breathe on it and see the CO2 go up a lot. If you read other people's comments about the battery not lasting long, I don't know, as I just leave it plugged in.

Firstly the device is compact and well made, ideal for a desk or lounge placement without being too intrusive. The screen is bright and clear to read head on, but quickly fades out when trying to look at an angle. The information on the screen is easy to understand with clear headings such as CO2, TVOC, HCHO, Temp and Humidity readings. The device also has an audible alert which will sound if reading levels increase to a point where your attention is demanded. The device can be changed between C and F very easily. The device has a built in rechargeable battery, which lasts around 8hrs - you can connect the device to a USB C power source to allow for infinite use. Switching on the device it goes through a self-test/calibration and counts down from 60 seconds before any readings start to appear. For the first few mins the device appears to work well and falls closely in line with my other more expensive air quality monitoring devices - however after only a few mins the devices readings go wildly off, the alarm sounds and the colour bar indication goes red! This is alarming and makes you think your air quality is almost dangerous to your health! I was receiving readings of CO2 levels being 3000ppm and TVOC levels at over 8mg/m2, requiring urgent ventilation of the area. When you turn off the device, followed by immediately turning it on again the levels return to normal again if only for a few mins. I tried several different placements for the device in different rooms around my home, some test were with the windows and door open and others a closed room, all resulted in exceptionally high readings. As a result of this problem the device became unusable due to the inaccurate readings. As a result of my personal experience i cannot recommend this device to others. ## Frequently Bought Together - WiFi Thermometer Hygrometer Monitor: Smart Humidity Temperature Sensor with LED Backlight Display, App Notification Alert, Data Storage Export, Temperature Humidity Gauge Compatible with Alexa(Round) - WiFi Door and Window Sensors,Tuya Smart Alarm with Free Notification APP Control Home Security Alarm System, No Hub Required,Compatible with Alexa, Google Home (1-pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/527169441-air-quality-monitor-indoor-temperature-humidity-sensor-with-co2-tvoc](https://www.desertcart.us/products/527169441-air-quality-monitor-indoor-temperature-humidity-sensor-with-co2-tvoc) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
