Indoor air quality monitors have emerged as invaluable tools for understanding and managing the air we breathe within our homes, offices, and schools. These devices provide real-time insights into the presence of pollutants, allergens, and other contaminants, enabling us to take proactive steps to improve our indoor environments.
We have found and tested the best indoor air quality monitors for formaldehyde, PM2.5, allergies and mold. Here are our opinions on choosing the best indoor air quality monitor and breathing better.
What is the Best Indoor Air Quality Monitor?
1. SAF Aranet4: Best for Home Overall (wireless)

Our Helpful review
I've owned several CO2 sensors, including 2 Awair Glow units, 1 first-generation Awair unit, 1 second-generation Awair unit, and a TIM10 CO2 sensor. While the TIM10 is my preferred sensor due to its accuracy, its drawback is the requirement for AC power. The Aranet4 caught my interest as a battery-powered CO2 sensor with app connectivity. However, it needed calibration out-of-the-box.
Comparing it to my reliable TIM10, the Aranet4 initially read about 75ppm higher. Despite the warning that calibration erases factory data, I calibrated it, verifying the results outdoors. Pre-calibration, Aranet4 reported 480ppm compared to TIM10's 380ppm. Post-calibration, Aranet4 aligned within 15ppm of TIM10, a success considering the low reading. Awair units, in contrast, bottom out at 400ppm.
In subsequent weeks, the Aranet4 consistently showed a 10-15ppm difference with TIM10, acceptable given Aranet4's battery power. The iOS app, while functional, lacks dark mode and experiences lag with increased data, which is not a big deal. The Aranet4's E-ink display is visually appealing, especially for travel. Its portability and accuracy post-calibration make it a valuable device.
2. AIRKNIGHT 9 in 1: Best for PM2.5 & Formaldehyde
Comprehensive 9-in-1 Monitoring: AirKnight's wireless indoor air quality monitor detects the main 8 types of air pollution, including CO2, VOCs, Formaldehyde, AQI, PM2.5 & PM10 Dust Particles, and more, ensuring real-time awareness for your family's health.

This is all new to me, as I'm more accustomed to old-school methods like measuring temperature and humidity. The idea of measuring pollutants never crossed my mind until the Canadian wildfires blanketed NYC in smoke during summer 2023.
When I received the monitor, I was unsure how to interpret it, especially as the PM2.5 readings didn't align with airnow.gov. After some research, I learned that Airnow provides an "Air Quality" index, while the AirKnight displays the actual amounts of measured pollutants. Although the readings differed, they were essentially in sync, offering different perspectives. Initially puzzled by the AirKnight's rapid readings, I later appreciated its sensitivity to subtle changes in our indoor environment. The device detected a spike in PM2.5 when my wife cooked spicy food, highlighting its capability to identify changes before my nose did.
I also noticed high CO2 levels with closed windows and how quickly they decreased upon opening. The device's responsiveness impressed me. For newcomers, I recommend spending a few weeks with the device to understand its patterns. Despite initial confusion, the AirKnight proved reliable. Additionally, its solid construction and U.S. origin, coupled with prompt and clear support, enhanced my overall satisfaction.
3. GOVEELIFE Smart: Best Price & Value (detects mold)

Our Helpful review
I like my GV smart air quality monitor. The accuracy is remarkable—I've observed it respond promptly when I start vaping in a room. The readings spike from 00, despite all my air purifiers, to around 600 or 700. Gradually, as the air purifier does its job, the levels steadily decrease. The monitor effectively informs me about the airborne particles, providing valuable insights.
Additionally, it excels at displaying moisture levels, with easily visible and dimmable lights that auto-adjust at specified times. The device itself is solid and aesthetically pleasing, seamlessly blending into my space. Govee has crafted an exceptional product, and I'm considering getting another one for my workplace.

It takes a week to obtain Radon and CO2 readings, but they align with other sensors I own. The green/yellow/red alert lights seem set at reasonable levels. Monitoring air quality reveals insights about the home beyond health and comfort. I utilize these devices to track activities like running the furnace or air conditioner with open windows.
Before Airthings, I tried a slightly cheaper brand to replace an Awair. Unfortunately, it was defective out of the box, and the indicator settings were impractical. Awair, my previous choice, ceased support, prompting me to switch. Airthings, priced similarly to Awair, boasts better quality, more readings, and additional functionality.
Although the display could be improved for low-light readability, the touchless feature minimizes fingerprint residue. Despite rising prices in the air quality monitoring market, Airthings seems the best value, offering comprehensive insights.

Our Helpful review
My pulmonologist recommended getting hepa air purifiers for my allergies and asthma. While researching, I discovered a review mentioning an AQI (Air Quality Index) or monitor to test the purifier's effectiveness. I never knew such a device existed; I thought specialists with expensive equipment were needed. If I knew about AQI earlier, I would have bought one ages ago.
This device has four settings. Initially using the frequent testing (R) setting, I found it confusing due to wild swings. Opting for setting A, the Temtop AQI remains stable, and after a week, the battery is halfway. To validate accuracy, I observed AQI mostly in single digits, but smoking shot it to 80, revealing the impact. It made me reconsider my habits.
Regarding my car A.C., despite two visits to the mechanic after a $2k overhaul, it ran cool, not cold. On my third visit, they claimed 48 degrees, but I knew it was wrong. Carrying the AQI monitor on errands revealed the interior never dropped below 90 (Arizona's heat). I plan to show the evidence to the mechanic, proving their initial tests were incorrect. Kudos to TEMTOP for creating such a useful and affordable device.
