TOP 12 Best Best Air Quality Monitors for Formaldehyde

#1 EGVOC-80 Air Quality Monitor Formaldehyde Detector

This device will satisfy almost everyone. It’s a compact, easy-to-carry, and functional device with a 2.8” LCD-display that can be placed anywhere you want. Thanks to the 2 power sources (battery or micro USB), you can use the detector without plugging it into the electricity, which is pretty convenient. This unit detects and monitors temperature (in C/F), humidity level, and a concentration of harmful substances including formaldehyde and dust matter (PM2.5/PM1.0/PM10). A built-in fan ensures real-time measurements. Combine the detector with your z-wave hub to create the most protected and smart home.

#2 EGVOC-100 Air Quality Monitor Formaldehyde Detector

Let’s take a quick look at another detector by EG. It provides very similar functionality but has a few differences that may force you to choose this model. First of all, the design is more compact, therefore, the display is smaller. This model monitors multiple measures of air quality: formaldehyde concentration, total natural & synthetic volatile organic compounds, and fine particulate dust matter measuring (PM2.5). It doesn’t measure temperature and humidity. Like the previous one, this monitor can be powered by a 2200mAh battery or by micro USB. Thus, it’s extremely convenient to take the device with you.

#3 E SUPEREGROW TVOC Air Quality Monitor Formaldehyde Detector

Of course, many of us look for something not expensive and efficient. Especially when it’s your first experience and you just don’t know what you need. Although the price of this model is not big, it still offers decent features. With the help of this small device, you can monitor the air condition and always know about the TVOC concentration. It includes chemical violates, harmful gas, smokes, and so on. The monitor will always show all the necessary information, such as quality levels and battery status. If some levels exceed the standards, the device will warn you immediately. You can also use the calibration function to ensure the accuracy of readings. Besides, dual power ways are supported, so you can install the monitor wherever you want with a breeze.

#4 BIAOLING Air Quality Monitor Multifunctional Accurate Tester

Regarding Formaldehyde detectors, we couldn’t forget about the one by BIAOLING. It accurately detects Carbon Dioxide, Formaldehyde, Volatile Organic Compound, and Particle Matter (PM2.5/PM10). All the levels, values, and real-time data are shown on the bright, colorful LCD. Moreover, the device will alarm you if any value exceeds the standards. The built-in 3000mAh battery makes it possible to use the device at any place. The standby time is from 8 to 12 hours, and it takes only 4 hours to charge the detector with a USB cable.

#5 Temtop LKC-1000S+ Professional Formaldehyde Monitor Detector

This model is designed for people who like multi-task devices. It’s a 9-in-1 detector that measures PM2.5, PM10, particles, HCHO (formaldehyde), TVOC, AQI, temperature, humidity, and histogram function (for the latest 12 hours). The accuracy of measurement is ensured by the advanced laser particle sensor and particle swarm optimization algorithm. Formaldehyde molecules are also accurately captured by the pre-calibrated electrochemical sensors. Due to the size of the device, the display cannot show a lot. Besides, it’s a TFT display, which is not good for some occasions. However, such a small size of a powerful 9-in-1 detector makes it easier to carry the device. Moreover, all of these small details allow the manufacturer to sell the product for a quite reasonable price.

#6 HEI LIANG AIR Air Quality Monitor Accurate Tester for CO2, Formaldehyde (HCHO)

Okay, so if you like big screens more than compact designs, you should consider this model as a solution. It has a 5.5-inch LED Screen Digital Display that shows everything you need. Built-in DART electrochemical sensors detect Carbon Dioxide (CO2), Formaldehyde (HCHO), and Volatile Organic Compound (TVOC) in the air. There is nothing complicated in operating this device, so you will easily figure out how it works in a few minutes. Although this detector is a little bit larger than many other competitors’ models, you can still take it with you. Thanks to the 2000mAh battery, it’s possible to run the device at any place. The problem is that such displays require a lot of energy.

#7 IGERESS Indoor Air Pollution Tester

IGERESS has designed the model that combines many cool features of the previous devices. It’s compact like LKC-1000S+, multi-functional like EG models, and accurate like other models of leading brands. With this detector, you can know the levels of formaldehyde (HCHO), volatile organic compounds (TVOC), PM2.5, PM1.0, PM10, temperature, and humidity. Dart sensors, laser sensors, and high-tech chips ensure the accuracy of readings. It’s easy to use this compact and easy-to-carry detector. The LCD keeps you informed about all the values so that you always know whether the air is clean or not.

#8 Atmotube Pro Portable Outdoor and Indoor Professional Air Quality Monitor

Although all models are designed for both indoor and outdoor use, this one is definitely the best for outdoor use. It’s not a low-budget model at all but it offers a great variety of functions. It accurately detects PM, volatile organic compounds (VOCs) like acetone, methanol, formaldehyde, and harmful gases. It also has a built-in weather station with atmospheric pressure, temperature, and humidity sensors. Another significant advantage is the long-lasting battery. It’s a first device that charges with a TYPE-C cable and can work for up to 1 week from one charge. To keep all the data and monitor the air quality whenever you want, simply download the app and connect the device to your smartphone.
