Indoor air quality has become one of the most relevant health topics in recent years. We spend over 80% of our time in enclosed spaces, breathing air we often assume is “clean” just because it smells nice or because we cracked a window for a few minutes. However, recent studies indicate that elevated concentrations of carbon dioxide (CO₂), volatile organic compounds (TVOC), or fine particles (PM2.5) can lead to everything from fatigue and headaches to poor concentration and even long-term respiratory issues.
With that context in mind, I decided to try the Qinux Beathix—a device that at first glance looks like a simple portable detector, but after two weeks of use has become a kind of invisible companion in my apartment, at the office, and even in the car.
What is Qinux Beathix?
Qinux Beathix is a multifunction digital air-quality monitor. Its strength is versatility: it combines electrochemical and semiconductor sensors to analyze not only CO₂, but also TVOC, formaldehyde (HCHO), fine particles PM1.0, PM2.5 and PM10, plus temperature and humidity. All told, a 13-in-1 that fits in the palm of your hand.
Unlike basic detectors that only alert when CO₂ levels are high, Beathix lets you see the full picture of what you’re actually breathing in each space. What’s nice is that the info is presented clearly on a 2.8-inch color TFT display, with real-time charts and readings.
Design & First Impressions
Taking the Qinux Beathix out of the box, the first thing that stands out is how compact it is: roughly 9 cm tall, 7 cm wide and 150 grams. Its ABS finish feels sturdy and pleasant to the touch, and the multiple ventilation slots not only help sample ambient air better, they also dissipate sensor heat.
The display takes up most of the front and is easy to read from any angle, even with strong daylight streaming through a window. The menu is simple and, although you can use it “plug and play” by just switching it on, it can also connect to TuyaAPP to monitor data on your phone and view history, which greatly expands its usefulness.
How does it perform day to day?
The user experience is very straightforward:
- Place Beathix in a room, on your desk, or even on your car’s dashboard.
- Switch it on and after a few seconds of calibration you’ll start seeing real-time values.
- If any parameter crosses a critical threshold, the device triggers a loud audible alarm.
During my tests I uncovered situations that would otherwise have gone unnoticed. In a meeting with six people in a closed room, CO₂ climbed above 1,200 ppm in just half an hour—right when we started feeling drowsy and losing focus. On another occasion, cooking with a brand-new pan, it detected a VOC spike that prompted immediate ventilation.
Performance & Accuracy
The detection range of Qinux Beathix is quite broad:
- CO₂: 400–6000 ppm, ±50 ppm accuracy.
- TVOC: 0–2 mg/m³.
- HCHO: 0–0.6 mg/m³.
- PM2.5, PM1.0, and PM10: up to 1000 µg/m³ with 1 µg/m³ resolution.
In practice, I compared the readings with a lab-reference monitor I borrowed (a Temtop M2000) and the differences were minimal: ±5% for CO₂ and ±8% for particulates. For a portable home unit, that’s excellent accuracy.
Battery & Portability
One of the big pluses of Qinux Beathix is its 2000 mAh USB-C rechargeable battery, which gave me 8–10 hours of continuous use without a power outlet. That makes it a perfect companion for the office, your kids’ school, the gym, or even hotels when you travel. Not relying on cables is a real advantage for this kind of device.

What Other Users Say
With over 1,300 reviews and an average TrustScore of 4.7 out of 5, Qinux Beathix stands out for its accuracy, ease of use, and the peace of mind it brings when making simple but important decisions: cracking windows during long meetings, airing out after cooking, or catching short-term pollutant spikes. Here are a few real-world experiences:
Emily Carter — ★★★★☆ (4.6/5)
“I work in an interior office and we used to hit an energy slump in the afternoons. With the Beathix we saw CO₂ jump past 1,200 ppm when back-to-back meetings piled up. Now we ventilate in time and focus is noticeably better. The app’s history has been super helpful.”
James Collins — ★★★★☆ (4.7/5)
“I bought it for my kids to keep an eye on their bedroom and study room. The screen is clear, the alerts warn without being annoying, and the battery lasts the day. It even flagged a TVOC spike when we set up a new shelf; we aired out and that was that.”
Sophie Harris — ★★★★☆ (4.8/5)
“I train at home and take it to the gym, too. Beathix helped me pick times with better air quality. It tracks PM2.5 and PM10; when the place is crowded and dusty, I know instantly. It’s small, solid, and very intuitive.”
Charles Bennett — ★★★★★ (4.9/5)
“I’m a teacher and use it in class. When CO₂ approaches the threshold, we open doors and windows and students perform better. It’s a device that ‘teaches’ you to ventilate. I compared readings with another reference meter I borrowed and they were very similar.”
Take advantage of this limited-time opportunity and get your Qinux Beathix to make informed decisions about ventilation and comfort at home, at work, or in your car. A discreet ally that lets you know when your air needs a breather.
Added Value vs. Other Devices
You can find very basic CO₂ detectors on the market from 40–50€, but they usually show little more than a number on a monochrome display. At the other extreme, professional stations run well over 300€. Qinux Beathix hits a very attractive middle ground:
- It’s far more complete than entry-level models (thanks to the “13-in-1”).
- It adds smart app features rarely seen at this price.
- It’s reliable and portable enough to justify the spend without creeping into prohibitive pricing.

Frequently Asked Questions (FAQ)
Do I need to calibrate it the first time I switch it on?
It’s best to leave Beathix in a well-ventilated spot for 10–15 minutes on first use to stabilize the sensors. After that, adjustment is automatic—no complicated steps.
What’s the difference between high CO₂ and “stale” air?
CO₂ is an indicator of insufficient ventilation: when it builds up from human respiration, cognitive performance drops and drowsiness rises. “Stale” air can also include TVOC (volatile chemicals from paints, cleaners, new furniture) and particles (PM2.5/PM10) that irritate airways. Beathix measures everything at once for a complete view.
At what values should I ventilate?
As a practical indoor guideline, try to keep CO₂ below ~1,000 ppm and PM2.5 below ~15–25 µg/m³. If Beathix triggers the alarm or you see spikes on the screen/app, ventilate by opening windows or improving airflow.
Where should I place the device for accurate readings?
Set it at breathing height (tables or shelves), away from direct open windows, stoves, or strong drafts that could skew immediate readings. In the car, the dashboard works well if it’s not in direct sun.
Can it detect cigarette smoke or vacuuming dust?
Yes. PM2.5/PM10 spikes with smoke, airborne dust, or heavy cooking. You’ll see almost instant increases on the display and in the app’s charts.
What exactly does “TVOC” measure and why does it matter?
TVOC covers volatile organic compounds from paints, varnishes, air fresheners, cleaning products, or new furniture. They can cause headaches, irritation, or discomfort. Seeing them in real time helps you ventilate right when needed.

Do I need the TuyaAPP to use it?
No. Beathix works standalone and its on-device display is very clear. The app is a bonus for viewing history, trends, and notifications on your phone.
What if cooking or new furniture makes the numbers jump?
It’s normal to see TVOC or PM spikes while cooking or after unboxing newly varnished furniture. Air the room for a few minutes and re-measure; Beathix will show levels dropping.
Can I use it in classrooms, clinics, or gyms?
Yes. It’s lightweight and portable, with audible alarms and a screen visible from multiple angles. Ideal for knowing when to ventilate without guesswork.
How does its accuracy compare with lab equipment?
For home use it’s very competitive. CO₂ ranges from 400–6000 ppm and comparison tests tend to fall very close to reference instruments. It’s a reliable tool for everyday ventilation and comfort decisions.
Does it require periodic maintenance?
Just wipe the exterior gently and avoid dust build-up in the vents. No consumables required. Keeping it away from humidity and extreme heat will extend its life.
Is it useful in the car for long trips?
Yes. On journeys with several people, CO₂ can rise quickly. With Beathix you’ll know when to crack the windows or boost ventilation to avoid drowsiness.
Conclusion
After two weeks of intensive use, Qinux Beathix has made me more aware of the invisible. I realized it’s not always enough to crack a window, and that small habits—like airing out after cooking or keeping an eye on levels during long meetings—can make a real difference in how you feel by day’s end.
At 79,95€ with a 50% launch discount, I see it as a sensible investment: not a “nice-to-have” gadget, but a genuine preventive-health tool. It’s no accident it’s racked up over 1,300 reviews with an average rating of 4.7 out of 5.
If you’re looking for a digital monitor for the air you breathe, Qinux Beathix is, as of today, one of the best companions you can have. Beathix becomes a quiet yet essential ally.
