The View Plus is the most complete home air monitor Airthings makes: radon plus particles, CO2 and VOCs, on batteries or USB-C. It is expensive, and worth it mainly if you want radon too.
The Wave Plus does the two jobs most homes care about after particles, radon and ventilation, in a battery-powered disc you can mount on a wall. It skips PM2.5, and costs less for it.
A continuous radon monitor shows your short- and long-term averages without lab fees. These are the best we found, and how to use one alongside the EPA's test-then-confirm advice.
No single gadget measures everything. Here is the order to do it in: a radon test, CO alarms, a monitor for the everyday readings, a moisture check, and a professional when the problem calls for one.
Radon testing is cheap and simple, and the EPA recommends it for every home. Here is how to do it properly, read the result, and decide whether you need mitigation.
A monitor is only as good as its sensors. We picked the ones with laser particle sensors, true NDIR CO2 and, where it exists, independent accuracy testing from South Coast AQMD.
Put the monitor where people breathe, not where air blows. Breathing height, a few feet from windows, vents and the stove, and, for radon, EPA's lowest-lived-in-level rule.
