Best Indoor Air Quality Meters in 2022

Last update: December 2, 2022

Are air quality sensors accurate?

Are air quality sensors accurate? This is a difficult question to answer, as there are a variety of air quality sensors on the market, and each one claims to be accurate. In addition, air quality can vary greatly from one location to another, so it is hard to say if one sensor is more accurate than another. That said, there are some general things to keep in mind when considering the accuracy of an air quality sensor. First, look at the sensor's specs to see how often it needs to be calibrated. If the sensor needs to be calibrated frequently, it

Can you test your own air quality?

You can test your own air quality by purchasing an air quality monitor. These devices will test for various pollutants in the air and give you a reading of the air quality in your area.

Do air purifiers help with air quality?

Air purifiers are designed to remove airborne contaminants from the air in your home. These devices can help to improve air quality and reduce your exposure to harmful pollutants. While air purifiers are not a cure-all for poor air quality, they can be an effective way to reduce your exposure to airborne contaminants.

Do air quality monitors check for mold?

Mold spores are present in both indoor and outdoor air. Air quality monitors can check for mold, but they do not measure mold spores specifically. The amount of mold spores in the air is affected by many factors, including weather, humidity, and the presence of other mold colonies.


Air Quality Monitor for PM2.5/PM10 HCHO TVOC Temperature Humidity YVELINES Professional Multifunctional Air Detector with Rechargeable Battery for Home Office Car and Various Occasion Review:


Especially after renovation, a good air quality monitor. We purchased it because we just painted the kids' room. It is fairly precise and provides the formaldehyde index, which is crucial information for safety. I used it to check the air quality. For a few days, we aim to leave every window and door open to enable fresh air circulate through the space. Using this monitor, we can then check to see if every index is within a safe range. Very well done!



IQAir [AirVisual Pro Air Quality Monitor] Compare Indoor & Outdoor Air Quality [PM2.5, CO2, AQI, Temperature, Humidity] Real-Time Air Quality & Forecasting, Historic Data, IFTTT Review:


Since I've had it for over a year, I've found it to be the most reliable of the three cheap air quality monitors I own. I also have a Dylos Pro that is more accurate but costs twice as much and has fewer wifi features.The AirVisual Pro may be used indoors or outdoors and is mostly effective for measuring particle matter. When used indoors, it can assist you choose when to run air filters. When used outdoors, it can help you choose when to open windows. We've put ours outside for almost a year, but out of the rain and sun, and it still functions and appears brand new.It also provides vital information on the ozone concentrations broadcast from the closest municipal sensing station. It does not record or monitor levels of VOCs or ozone.We also have an Awair and a Foobot for comparison. Both of those include capabilities that the Airvisual Pro lacks, like as VOC measurement and IFTTT compatibility, allowing you to, for instance, arrange them to automatically turn on air filters when the dust level rises. I'm hoping that one day AirVisual will include these functions. The issue with Foobot and Awair is that their dust sensors, which also have subpar VOC sensors, are incredibly unreliable and inconsistent.In terms of particle level measurement, the Dylos Pro outperforms them all. It is the only one that can compare PM2.5 levels to PM10 levels, which is helpful for, among other things, telling pollen from pollution. However, compared to the AirVisual, the Dylos is more expensive and less useful as a 24-hour monitor.Each of the four products has a purpose, and while none of them is perfect, the AirVisual Pro is probably my favorite because it accomplishes its objectives quickly, affordably, and accurately.



Air Quality Monitor Yvelines Accurate Tester for CO2 Formaldehyde(HCHO) TVOC PM2.5/PM10 Multifunctional Air Gas Detector Real Time Data&Mean Value Recording for Home Office and Various Occasion Review:


This has made me aware of some significant problems with my current home. There are some locations in my home where the air quality is not nearly as good. I think one of the problems is an old carpet. However, if you frequently burn candles that aren't entirely natural or otherwise known as inexpensive candles, you should watch the movie. This made clear to me how dangerous those are when you're enclosed. It must sit for a short while after measuring in order to obtain a calculated reading for CO2 and HCHO Formaldehyde. There is no doubt that certain tests take longer than others. I adore the ease with which you can switch between the several tests. During testing, the battery doesn't last too long. Without charging, it can be used for testing for around 4 hours. The real-time data for PM2.5 and PM10 is amazing.I had no idea how awful the air was in some areas of my home or that different candles let off such toxins, but this device is incredibly useful. I would suggest this item to anyone because using it was such an eye-opener. It performed equally well outside, and I could use the outside air to verify the readings from within. In order for it to acquire a broad reading of the entire area so that you can move it around and look for hot spots, for lack of a better description, I would advise letting it sit in a room free from plastic bottles and other objects.When compared side by side, this equipment was extremely accurate, according to a friend of mine from the Hazmat response team at the Fire Department. To avoid becoming overwhelmed by all the features, I advise you to familiarize yourself with each of the things it tests for. However, I am the type of person who would prefer to know than to continue living in blissful ignorance.



GZAIR Indoor CO2 Meter, Temperature and Relative Humidity Wall Mountable Carbon Dioxide Detector, Air Quality Monitor, NDIR Sensor, 0~5000ppm Range Review:


Although there is space for improvement (see recommendations below), I enjoy it:1. It would be convenient to have a 5V power adaptor provided (instead of just a USB cable). The needed power adapter's milliamp output isn't even mentioned in the instructions, but I tried multiple 5V adapters I already had (500mA, 1A, and 2A) and they all functioned. The machine must always be hooked into a power adapter in order to operate because there is no internal battery or capacitor. Additionally, the accompanying USB cord is far too thick and cumbersome.2. The documentation does not provide instructions on how to keep the display backlight on; it typically turns off after 60 seconds. A fix for this, though, is to press Menu, Enter, Enter, and then Menu again. When you do this, the backlight will stay on until you press another key, like Enter again, at which point it will turn off after 60 seconds.3. The beeper is obtrusive. When a button is pressed or power is applied, a loud beep is produced. However, take aware that pressing the Enter button will turn on the backlight silently (e.g. to avoid waking up someone in another room of the house). Any nighttime power interruption is sure to cause a loud beep that will wake everyone in the house.4. It would be convenient if the readings could be accessed externally from a phone or computer via Bluetooth or a USB link. (At the moment, only the screen can display the readings.)5. It would be convenient if additional air quality measures could be assessed in addition to CO2 levels (although many other meters have chemical sensors and I do appreciate that this meter uses an NDIR Infrared sensor for CO2).Keep in mind that pressing the buttons only needs a very faint touch. Holding down the Enter key for too long will cause all settings to be reset and all log data to be cleared.I'm not sure if this is accurate, but I have seen that the CO2 readings rise when the relative humidity is higher, such as when a shower is being run nearby.



Awair 2nd Edition Air Quality Monitor Review:


We are in Northern California and have taken refuge in our home to escape the smoky air brought on by the several wildfires. We bought this monitor to find out if the air quality inside our home was indeed better than the outdoors. The level 10 filter reduces the 2.5 particle count when we operate our HVAC. The number increases each time we open a door. The air in our home was generally good when the filters were functioning. We attempted it outside, poor air (as expected). The air was marginally better than outside when we tried it at our neighbor's home, where air filters haven't been used. The CO2 value increases when we cook or breathe into it. When my spouse attempted to fart in front of it, all the values increased:-). Knowing that our air filter and air purifier are working properly and that our interior air quality is at least acceptable has been comforting overall. I had originally intended to purchase more air purifiers, but I now realize we don't need them.



My Mold Detective MMD103 Mold Test Kit, 3-Room Kit Review:


You must first be aware that paying extra to have the cassettes checked will be your responsibility. There are 4 cassettes in this kit (1 for outdoor sample and 3 for rooms in your house). It will cost $140 to have all of those tests ($35 for each cassette, including the outside). To test 3 rooms in your home, you will therefore need to invest roughly $200, including this kit.The cost of having a professional inspect one room was quoted to us as $250 to $300. Although expensive, it was nonetheless less expensive than it otherwise would have been.The test results are fairly thorough and very simple to interpret. The levels for 4 major mold groups (Penicillium/Aspergillus, Cladosporium, Basidiospores, and Ascospores) are broken down in the study. It determines a score for each room for each group and then tells whether those values fall into the "normal," "slightly raised," or "elevated" levels.In our case, one group was elevated (in the red) in each of the three rooms. Our values, however, were far lower than the levels that other websites discussing that type of mold would deem to be of concern when we compared them. There doesn't appear to be a set acceptable threshold, and each organization chooses which levels need to be corrected.Overall, I'm happy we tested because we now know. Although it wasn't cheap, I am confident in the report's values.



Air Formaldehyde (HCHO) DIY Test kit - Know What's in The Air That Surrounds You (Pack of 1) Review:


I recently moved into a new house, and after a few months I started experiencing periodic eye burning and sore throats. There was a faint smell that I mistakenly identified as formaldehyde, too. I looked online to see if I could locate a simple, quick test to determine whether we were experiencing a formaldehyde problem. On Amazon, I discovered the Air Formaldehyde (HCHO) DIY Test kit, and I decided to give it a try considering the low cost. It was really simple to use the exam. The fact that the date on the package was one month in the past at first worried me, but after communicating with the seller I learned that this is the production date. Because expiration dates are so common, I didn't consider the possibility that the production date would be the cause. I carried out the test in accordance with the directions in a room that I could readily lock off. It took less than an hour to complete the process. My levels were found to be between 0.20 and 0.25 according to the test. As some people have mentioned, it might be challenging to determine the levels using a color test strip, so I emailed the seller with a picture of the results to get their take on it. They backed up what I had noticed. With these findings, I got in touch with my builder. A business that performs air analysis and specifically tests for formaldehyde was sent in by the builder. Their test cost close to $1000 and took approximately three weeks to produce findings. Their findings supported the outcomes of the test kit I purchased for $10.00. The builder is currently doing more tests to determine the formaldehyde's source. I am ecstatic with your test kit and will use it to track the formaldehyde levels as we try to remove them from my house.



Air Quality Monitor, Formaldehyde Detector, Pollution Meter, Sensor, Tester; Detect & Test Indoor Pollution, TVOC Volatile Organic Compound Gas, PM2.5 2.5 Micron Particulate Matter Dust; eBook Review:


I was somewhat astounded by the quality of the wrapping and the item itself when I first opened the box this device was supplied in. Since I've been using it for a few days, I've been pleasantly surprised by the device's accuracy and sensitivity. An absolute must for allergy sufferers or if members of the home are frequently ill.I strongly advise that you adhere to the instructions, especially when unpacking the item for the first time. To allow all sensors to vent, it is advised that you leave the device outside in the open for at least 30 to 60 minutes before turning it on. Some sensors have internal heating elements that are essential to their operation. Let everything breathe for the optimum effects before turning on the power.As soon as I got the tool operating, I started using it to measure other locations. I used it at work to check the air quality in one of the datacenter laboratories, and the results showed that the HCHO, TVOC, and PM2.5 levels were all zero. Because the numbers changed very slightly every time I passed the gadget while I was in the lab working, the device essentially offers real-time statistics (i.e. TVOC 0.001 increased to 0.005, PM2.5 went from 000 to 002, etc). After a brief period, all of the numbers reset to zero.Because of how sensitive this gadget is, the measurements appeared in real time as I moved around my house. Readings started to fall fairly low as soon as I entered the hallway. The HEPA air filter in the hallway, which is close to the cat litter, is the cause.This gadget is so perceptive that it can distinguish between when I drive with my windows down on I-280 and I-101. I-280 is a freeway that is entirely surrounded by woods where I reside, whereas I-101 is primarily industrial. As you travel along I-280, the readings are substantially lower. See? We can greatly benefit from trees in maintaining clean air!Being so delicate, this gadget almost makes using the restroom enjoyable. Fecal matter will show a higher TVOC rating on the device since it contains more VOCs due to the sulfurs and numerous other chemicals your body need for digestion. The TVOC value rises the more foul the poop! Do you or someone else smoke? Run this gadget while smoking to see how smoking affects the quality of your air. No joke: secondhand smoke!like me, a resident of California? Due of the numerous wildfires burning throughout the state, bring this portable, rechargeable device with you whenever you walk outside to monitor the air quality. This device can only provide you with information; it cannot do anything other than provide you with your Air Quality Index (or AQI). Very useful for enabling you to take additional safety precautions (especially if you have asthma, such as myself).Use this device to verify the efficiency of your air purifier because it measures the various AQI values in real time! purchased a new car? Take a reading inside your new automobile using this gadget. Believe it or not, the formaldehyde emissions from curing glues and resins are what give new cars their distinctive smell. new furniture purchased? Check the HCHO levels that new furniture can possibly emit using this instrument. The majority of furniture is composed of particle board or MDF. Particle boards are made of pieces of wood held together by formaldehyde-emitting chemicals and glues.The following, in my opinion, would have made this product cooler: * The capacity to preserve histograms when measurements are initiated. To access historical graphs, you must remain on the graphs page. The ability of the device to save calibration data between power cycles; the inability to view previous measurements if you leave the page and return to it. The values may fluctuate somewhat the next time you power cycle the gadget after calibrating and zeroing it out.* The capacity to export results over time * The capacity to modify the color scheme for the user interfaceThis device is ideal for making spot measurements to determine the exact state of the environment. Past readings won't be visible to you. I heartily advise purchasing this item!



Formaldehyde Air Rapid Test Kit, 5th Generation, DIY Testing Indoor Air, North America Edition Review:


Since he was unaware that DIY tests were available but I knew of a buddy who had previously used one, I got this for my elderly neighbor to use as a prescreen before hiring professional assistance. In all honesty, all of the DIY tests available on Amazon appear to function similarly. The reason I chose this one is that it is the most recent model and currently offers the best pricing. My neighbor's test was set up with my assistance, and I received the results over the weekend. Thankfully, his result is unquestionably safe. He had saved both money and headaches, which made him ecstatic. Overall, I believe that this test performed as planned. The test is simple to set up, and the instructions are straightforward. In our situation, the result is quite simple to read. For all of these do-it-yourself exams, making a decision when a result is on the line might not be as simple.



Temtop M2000C Air Quality Monitor for PM2.5 PM10 Particles CO2 Temperature Humidity settable Audio Alarm Recording Curve Easy Calibration Colorful Display Review:


This was probably constructed to a four-star standard. There are no problems, however the buttons, in particular, should be improved. The screen and the physical buttons below it are covered by a single piece of flexible resin. Because of this, pressing the buttons can be a little challenging. Although individual rubber buttons would be nice, they are really not necessary at this price point. The software is where this item really shines. It loads quickly, responds well, and is entirely in spoken English. The software gets five stars. The usability has me very, very pleasantly pleased. A particularly nice feature is the bar graph. It automatically scales with time. Instead of resetting after 30 or 60 minutes, it loses "resolution" over time by averaging longer and longer time periods. really helpful I purchased this to monitor the amount of dust particles in my shop to make sure my dust collection system was functioning properly. Although there are cheaper models available that would work for this, I loved the concept of having CO2 monitoring as well. It turns out to be really helpful. The C02 levels in my wife's SUV, which has five people inside and the A/C set to recirculate, are above 5000 ppm! Within 30 seconds of turning off the recirculation, the levels were back under 1000.comes with a tiny blow-molded plastic case. At this price, it's still a great place to store the gadget, but don't count on it to offer much protection.To be fair, I don't have another device to compare the readings from this one to, but under known circumstances, it performs as predicted, so I have no reason to doubt it.definitely would purchase again.


How accurate are indoor air quality monitors?

Indoor air quality monitors are devices that are used to measure the level of pollutants in the air inside a building. They can be used to measure a variety of different pollutants, including carbon monoxide, dust, mold, and volatile organic compounds. Most indoor air quality monitors are designed to measure only one type of pollutant, so it is important to choose a device that is appropriate for the specific needs of the building. Additionally, indoor air quality monitors are not always accurate, and their readings may vary depending on the conditions inside the building.
