10 effective air quality monitors for people with allergies

Persistent allergy sufferers may be surprised to learn that even the tidiest indoor spaces can be full of pollutants. From dust and fungi to chemical fumes and dander, inside air carries so many allergens that determining the cause of your discomfort can be a challenge. To take a scientific look at what irritants may be floating around inside your home or office, and to decide the most effective manner by which to reduce them, you need an air quality monitor.

In this article: Airthings 2930 Wave Plus, Temtop Air Quality Monitor and Temtop LKC-1000S Air Quality Monitor.

What can air quality monitors detect?

Air quality monitors can detect the following issues, any of which can adversely affect allergy sufferers:

• Excessive carbon dioxide. This results from poor ventilation. Too much carbon dioxide can cause headaches, dizziness and nausea.
• Volatile organic compounds. VOCs are gases emitted by everything from carpets and shower curtains to cosmetics and cleaning products. They can build up quickly and lead to illness.
• Radon. Long-term exposure to this naturally occurring radioactive gas can cause lung cancer.
• Particulate matter. Particulate matter, or PM, is the mixture of tiny solid and liquid matter that collects on surfaces and floats in the air. The most common offenders, with regard to allergic reactions, are pet dander, dust and pollen. 
• Improper humidity. Too much indoor moisture allows mold, dust mites, insects and other sources of allergens to thrive. Too little, however, can cause otherwise harmless particles to dry out and become airborne irritants. 
• Virus and mold-friendly conditions. Some monitors can use the data they collect to let you know directly how conducive the conditions in your home are to the survival and spread of germs and fungus.

Air quality features to consider

• Pollutants detected. Make sure that the monitor you select is designed to detect a wide range of pollutants so you can make an educated assessment of your air quality.
• Smart home integration. Many monitors work with Amazon, Apple or Google smart homes and assistants. If you want to integrate your monitor, make sure you select one that is compatible with your preferred platform.
• Battery life and power options. Most air quality monitors have a short battery life. To keep your monitor on at all times, purchase one that can be powered via USB.
• Easy to read. While most monitors feature a simple display and color-coded air quality indicators, some show more data than you may be interested in parsing through. Make sure that the monitor you purchase lets you make quick, easy observations.
• Alarms. Some monitors let you set up alarms that will sound when certain pollutants reach dangerous levels.
• Air quality tracking. If you want to keep a record of your air quality over time so you can see progress or work on improving it with a purifier or other means, buy a monitor that stores its readings in the form of charts and graphs.
