Anyone here bought a cheap air quality detector for home use?

Honestly, most budget ones are pretty useless and super inaccurate.

They use low-end cheap sensors with no real calibration. Readings jump randomly from temperature, humidity, cooking smoke or even perfume.

I’ve seen the same room give totally different numbers, way off from professional devices. Many basically just show fake stable numbers to trick you.

It’s frustrating when you rely on it to open windows or run an air purifier, but the data is totally unreliable.

Save your money — skip the ultra-cheap no-brand ones. Spend a little more for a decent sensor if you actually care about accurate air quality readings.
