Air quality is a big deal in 2019. We’re more aware of the dangers we face just by sitting in our own homes. You could be breathing in toxins, chemicals, dust, and many more things that could have serious implications in the future. So, what can we do about it? Well, fortunately, there are hundreds of products out there that can improve the air quality in your home. The only problem is – they all do a different thing. So, you need a way of analyzing your air quality before you can go about fixing it. That’s where air quality monitors come in. They use sensors to find out exactly what is in the air you’re breathing so that you can take steps to improve it. Here’s our list of the best air quality monitors on the internet.

The Best Air Quality Monitor

1
Awair Element Indoor Air Quality Monitor

product-img

Awair is one of the biggest names in the world of air quality monitors. They take smart technology, interior design, and the latest in air quality monitoring technology and put it into every product they make. Our favorite product in their range is the Awair Element Indoor Air Quality Monitor. It tracks the five most important elements of air quality – CO₂, VOCs, PM2.5, temperature, and humidity. You can read these measurements in real-time using the Awair app to get a picture of your home’s air quality, so you take steps to improve it. 

The main reason for buying the Awair Element over the other air quality monitors in this list is the way it looks. It looks like a modern speaker or alarm clock, which means you’re not going to be embarrassed to have it in your home. You can also integrate it with Alexa or Google Assistant and control your air quality using just your voice. If you’re looking for the best air quality monitor on the market, you’ve found it. And if you liked this product, you will surely be interested in some of these amazing smart air purifiers from our list.

EG AIR Air Quality Pollution Monitor

product-img

The EG Air Monitor is one of our favorite budget options on the market. It’s around $100 cheaper than most of the professional-standard pollution monitors around, so it doesn’t have quite the same accuracy or number of features. However, if you’re looking for something entry-level, that will give you a good insight into your air quality, this is a great product.

One of the main things we like about it is that it comes with an LED screen. A lot of modern air pollution monitors require you to connect the device to your smartphone or tablet, but with this product, you can just pick it up and check your readings. Having said that, it still does come with a corresponding app, if you want more detailed analysis.

It measures temperature, humidity, VOC, and fine dust matter, but doesn’t measure CO2 like the other products. And, it gives you a general overall reading of your air-quality that is displayed using a smiley face. For more quality products for your home, check out our guide to the best ozone generators.

It’s a handheld device that you can use in your home or in a business setting like an office or warehouse. It has an advanced sensor that detects PM2.5, PM10, particles, CO₂, temperature, and humidity. That gives you a pretty complete view of the quality of the air you’re breathing in. It has a small TFT color LCD screen that displays the data and is powered by a 2200 mAh rechargeable lithium battery that provides around six hours of battery life. Another feature we like is the air quality alarm, which lets you know if the measurements rise above a set level.

IQAir AirVisual Pro Air Quality Monitor

product-img

The IQAir Air Monitor is one of our favorite premium products on this list. It does the same basic job as the cheapest air monitors, but the readings are generally more accurate, and they offer better connectivity. In simple terms, if you really want the most accurate reading, you should spend more money. But not everyone needs to know exactly what their home’s levels of CO2 are.

The stand out feature on this air monitor has to be the large LED display. It’s super bright and easy-to-read thanks to the color-coded smiley face system and the large font. You can set it to display exactly what you want to see at a glance, including the weather and air quality outside. As soon as you power it up, it can detect your location and display the readings from the nearest monitoring station. This makes it a much more comprehensive tool than the other air monitors we’ve featured.

It’s a professional-grade monitoring system, which means it’s super accurate. It specializes in measuring PM2.5, using its high-precision laser technology. And, it’s got an industrial grade CO2 sensor. On top of that, it can measure temperature and humidity accurately.

The smart home integration technology in this monitor is among the best on the list. It can be set up to control your connected home technology and send alerts to your smartphone when the air quality reaches a certain level. But this product stands out because you can compare the air quality indoors to the air quality outdoors. This, along with the fact that you can check your air quality history, gives you a real indication as to whether the steps you’re taking to improve the air quality are working. For example, if you run an air purifier in your home, you should be able to see a marked difference after a couple of days. Don’t forget to also check our guide to the best portable air conditioners.

Plume Labs Flow The Personal Air Pollution Sensor

product-img

Our last product on this list is the Plume Labs Flow. Just from a quick glance, you’ll probably notice that this product’s a bit different from the rest. It’s the leather handle that gives it away. And the fact that it’s tiny and weighs just 70g. The reason for this is that it’s designed to be mobile so you can take it anywhere with you. This is a product for the truly vigilant among you that want to know about the quality of the air wherever you go.

It works by letting air pass through the tiny holes in the shell and shooting a laser into the air. This laser detects the particles of air and records the data. Because it’s designed for mobile use, it focuses on three primary measurements – Nitrogen Dioxide (NO2), Volatile Organic Compounds (VOC) and Particulate Matter (PM2.5, PM10). These are the three main pollutants that have an adverse effect on our health and the most common pollutants you’re likely to encounter when you’re out and about.

Of course, like all air quality monitors, it sends the recorded data to a corresponding app. You can get a minute-by-minute breakdown of your exposure and it can even build up an air-quality map of the places you’ve been. That makes it perfect for people on the road a lot because it can tell you places you should be avoiding. It’s not the most comprehensive air quality monitor, but we love the fact that it’s portable and measures as you go.

VSON Air Quality Monitor

product-img

The VSON Air Quality Monitor is one of our favorite handheld monitors. If you want a portable device that can read the air quality anywhere, this is one of the best. It provides a pretty complete view of the air quality. It shows the temperature, humidity, PM1, PM10, PM2.5, TVOC, and HCHO (formaldehyde). The only thing it doesn’t provide is the CO₂ level, so you’ll need a separate device for that. One of the best things about this air quality monitor is how portable it is. It’s powered by a 1000mAh battery that gives it around 3-6 hours of life. Plus, it weighs just 170.5g, which means you can carry it around in your pocket without really noticing it.
