The quality of the air you breathe has an enormous impact on your health<\/a>\u2014poor air quality is linked to a host of health issues, and is believed to be responsible for millions of deaths<\/a> globally every year. And it\u2019s not just physical health\u2014there\u2019s growing evidence<\/a> that poor air quality can negatively impact your emotional and mental health, as well.<\/p>\n While you might pay attention when the nightly news or your weather app flags poor outdoor air quality<\/a>, you should also be paying attention to indoor air quality<\/a>. Americans spend about 90% of their time in their homes, after all\u2014and the air quality indoors can be exponentially worse<\/a> than outside. If you want to protect yourself, monitoring your home\u2019s indoor air quality (IAQ) with a monitor is a good idea. Here are some of the best ones you can buy right now.<\/p>\n Best simple monitor<\/p>\n The SAF Aranet4 Home<\/a> is a small, battery-powered air quality monitor that you can easily move from room to room with you, or take with you when you travel to monitor the air quality in hotel rooms and other spaces. The battery life is terrific (up to four years) and the app is straightforward and easy to use. It monitors carbon dioxide (CO2), temperature, relative humidity, and atmospheric pressure\u2014but not particulates in the air, like dust. If all you want is a simple and portable monitor, this is a terrific choice.<\/p>\n <\/p>\n <\/a> If you find the volume of data being dumped into your head every day overwhelming, the PurpleAir Zen <\/a>is perfect: This air quality monitor uses a simple color code to tell you how the air is at any given moment. A soft green glow means everything is good; yellow means it could be better; orange means folks with sensitivities or health issues should be careful; and red, purple, and violet mean the air is dangerous. You can use it indoors or outdoors, so you can see at a glance if the air you\u2019re breathing is dangerous or not.<\/p>\n Best budget monitor<\/p>\n If you want to track the air quality but you\u2019re not looking to spend hundreds of dollars, this nifty model from Ikea<\/a>, of all places, is a great choice. It tracks particulates in the air as well as volatile organic compounds (VOCs), showing you at a glance how dirty the air around you is at that moment. While it\u2019s designed to be hooked into Ikea\u2019s smart hub technology (and can be paired with an Ikea air purifier for a total air-quality solution), it works just fine as a standalone.<\/p>\n What do you think so far?<\/p>\n Best all-around monitor<\/p>\n The Airthings View Plus <\/a>offers a comprehensive overview of your indoor air quality, measuring radon, particulates, CO2, VOCs, as well as temperature, humidity, and air pressure. The radon monitoring is a great extra feature, as radon is almost undetectable unless you\u2019re looking for it. There are some minor downsides: It must be connected to both the internet and an app on your phone or tablet to work, and the display is very small, so it can be hard to see what\u2019s going on from across a room (though you can always just look at the app).<\/p>\n <\/p>\n <\/a>![\"SAF](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/09\/hero-image.fill.size_autoxauto.v1724990787.jpg\")
