It’s 2021 — we know exactly how many calories are in our food and drinks, things like fitness trackers can tell us exactly how much exercise, sleep and recovery we need — we have a ton of information about what goes into our bodies and what it needs. But one thing we probably don’t give enough attention to is the air we breathe. Really though, do you know what you are breathing in right now? The best air quality monitors let you keep a close eye on indoor air quality, which can often be worse than the “fresh air” outdoors.
Sure, you can get air-quality reports from your local weather channel or from the app on your phone about the outside air quality, but what about your home or office? That’s where air quality monitors come in. The best home air quality monitors detect harmful chemicals, gases and fine particles that can negatively affect your respiratory system.
When you are looking for an indoor air quality monitor, you’ll see a handful of acronyms tossed around that pertain to what the monitors detect. Here’s what they mean:
- Volatile organic compounds (VOCs) – Gases emitted from certain solids or liquids that may have short to long-term negative effects on respiratory health
- Fine particles (also known as particulate matter) – Particles that are 10 micrometers or smaller that can be inhaled that may cause negative effects to the lungs and heart
- Total volatile organic compounds (TVOC) – This is the total combination of all VOCs in the air.
- CO2 – a greenhouse gas that is harmless in small quantities (we breathe out Co2), but high levels of CO2 can negatively affect cognitive function and sleep. Left unchecked, CO2 leaks are deadly.
That all seems scary, but thankfully, home air quality monitor helps detect and inform you when any of the above get to levels that are harmful to your health. Keep in mind, air quality monitors only detect these particles and gases, they don’t eliminate them. You’ll want to pair an air quality monitor with an air purifier or find a smart air quality device that can connect to your smart home system to automatically take action when air quality reaches harmful levels. You can also check out the EPA’s guidelines on how to reduce exposure to harmful air particles at home.
You know virtually everything that goes into your body, now it’s time to take control over what you breathe. Below you’ll find our recommendations for the best air quality monitors to put your mind at ease about the air you are breathing.
