Good Monitor
Really like being able to check air quality as I walk by, especially when cooking. Since purchasing this I have had 3 other family members purchase. My only complaint is that it requires a power supply.

The Only One That Didn’t “Zero Lock” — Worth Keeping
I never planned on getting an air quality monitor — until roof repairs at my apartment filled the air with chemicals for weeks. I needed reliable TVOC and HCHO readings.After trying 6 monitors, this was the only one that didn’t freeze those readings at 0.000. Others needed constant reboots or hours outside to reset. This one just works — and if it ever gets stuck, it recovers quickly on its own.It’s not perfect (I’m still skeptical about the PM2.5/PM10 accuracy), but for TVOC/HCHO trend detection, it’s responsive and consistent — even in tough tests like a sealed box with old nail polishes (see pics for readings at 0 and 1 min).By default, it shuts down every 11 hours to re-baseline. I disabled that, but I still take it outside occasionally to reestablish a clean-air reference.⸻✅ Pros• Rarely “zero locks”• Recovers without reboot• Clear display• Detects real VOC changes⚠️ Cons• PM2.5/PM10 readings seem off• No data export or app• 3-min warm-up• No brightness control• Clock doesn’t show AM/PM• Brief resets cause AQI spikes• Slow to charge⸻Paid ~$75 on sale. It’s not lab-grade, but it’s the most consistent and usable VOC/HCHO monitor I’ve found — and that’s saying something.3.5 stars, rounded upHope this helps you skip the return spiral I went through !

A life saver!
Having this probably saved my life! Moved to new home. All of a sudden I awoke at about 2:00 AM frantic. I knew something was wrong but didn’t know what. Drove to ER. Parked the car and stepped out. Passed out. Was found on the ground. Since then, using their suggestion, I bought this. for my son and his family also!

Piece of mind
Easy to use. Simple display and eaSy to understand reference guide. I was concerned about particulates and CO2 as well as formydehyde possibly coming from new furnishings. It gives me piece of mind. I don’t run it non-stop- just periodically.

Very accurate
Works great perfect and accurate. Also climbs faster in true time than others I’ve used.

Great Overall Air Quality Monitor — But CO₂ Sensor Needs Work
Great Overall Air Quality Monitor — But CO₂ Sensor Needs WorkI purchased two Air Knight units — one for the first floor and one for the second — as part of my ongoing journey to improve my home’s air quality. As someone healing from CIRS and MCAS due to mold exposure, having accurate and consistent air data is incredibly important to my recovery and peace of mind.Overall, I really like the unit. It has a sleek look, is easy to read, and the sensors for PM2.5, PM10, temperature, and humidity seem very well calibrated and reliable across both devices. I truly appreciate how comprehensive the data is without needing a Wi-Fi connection or app.However, the CO₂ sensor on one unit has calibration issues that make it difficult to trust. It’s extremely sensitive and often reads significantly higher than my other monitors — enough to cause concern when there may not actually be one. This makes it hard to rely on the CO₂ data as a daily baseline, especially when everything else reads within normal range. If the rest of the unit wasn’t so good, I might have returned it for this reason alone.Suggestion to the manufacturer: Consider removing the CO₂ feature (or improving its calibration significantly), and instead add PM1.0 to the dashboard — this would keep the focus on particle-based pollutants, which are critical for sensitive individuals like me.That said, I still think this is one of the best air monitors I’ve tested — and I’ve tested many. With a few tweaks, it could be perfect. I plan on keeping one unit and returning one with the c02 sensor issue and compare with 2 more air quality monitors before my return window closes.
