The Airthings View Plus measures CO2, PM2.5, VOCs, radon, temperature, humidity, and atmospheric pressure. It connects to Alexa, Google Assistant, and IFTTT. The e-ink display is customizable. The battery runs on six AAs. And the companion app shows historical data in clean, readable charts.

The radon sensor is the standout. Most consumer air quality monitors skip radon entirely. The Airthings doesn't. That matters if you're in an area with known radon risk or if you have a basement with minimal ventilation.

I own one. But I didn't buy it because I assumed I needed six sensors. I bought it after investigating my home and identifying that specific readings would help me confirm and track what I'd already found.

The "Measure Everything" Trap

The Airthings View Plus is the monitor people buy when they want to cover all their bases. CO2, particles, chemicals, radon. If it's in the air, this thing tracks it. The logic feels sound: why guess which sensor you need when you can just get all of them?

Here's the issue. Six sensors produce six readings. But readings without context are just numbers on a screen. Your CO2 might be fine while your PM2.5 is elevated. Your VOCs might spike in the evening. Your radon might register at 2.1 pCi/L. What do you do with that? Which number is the one connected to the headaches you've been getting? Is the PM2.5 from cooking, from your HVAC, or from dust you're kicking up off old carpet? Is that radon reading a concern for your specific home layout, or is it within normal range for your region?

The Airthings gives you the data. It doesn't interpret it. It doesn't connect it to your symptoms. And it doesn't tell you what to fix first.

$300 Is a Lot to Spend Without a Plan

Most monitors on this list cost $100 to $200. At $300, the Airthings is a significant investment. It makes sense for some homes. But spending that much becomes harder to justify if you're not sure which of those six readings actually matters for your situation, which room to put it in, or whether your real issue is something no sensor can detect, like moisture accumulation behind a wall or dust mite buildup in aging bedding.

I got value from mine because I already knew what I was looking for. The Airthings confirmed what investigation had surfaced. It didn't replace it.

What a Free Assessment Does That a $300 Monitor Can't

Identifies which factors matter in your home. The Airthings tracks six pollutant types. The assessment tells you which of those are likely relevant to your situation before you spend a dollar.

Tells you where to place a monitor. A single device in the wrong room gives you accurate data about a space that isn't causing your issues. The assessment narrows down which rooms have the most concerning patterns.

Catches what sensors miss. Moisture behind walls, dust accumulation patterns, HVAC distribution problems, behavioral factors like cleaning habits or ventilation timing. No monitor detects these, and they're often the root cause.

Gives you a framework for interpreting readings. A VOC reading of 400 ppb means something different if it's coming from new flooring versus cleaning products versus off-gassing furniture. Context changes the response.

Prevents buying the wrong tool. If your issue is dust mites or mold behind drywall, no air quality monitor will find it. 16 minutes could save you $300 and redirect you toward what actually helps.

The pattern: The Airthings checks more boxes than anything else on this list. It still can't identify where mold is growing, what's generating your dust, whether your HVAC is distributing pollutants between rooms, or which of its six readings is the one connected to how you feel. More sensors is not the same as more answers.

Know What You're Dealing With First

A 16-minute assessment identifies the factors in your specific home so you know what to track, where to track it, and whether a $300 multi-sensor monitor is even the right tool. If the Airthings turns out to be a good fit, you'll use it with direction. If a $129 single-purpose monitor or a no-cost behavioral change is all you need, you'll know that too.

Which pathway should you select?

Cognitive for headaches, brain fog, or fatigue at home

Respiratory for congestion, sneezing, or coughing

Odors for unusual or unpleasant smells

Preventive if nothing's wrong and you just want healthier air

If the assessment identifies factors that align with what the Airthings tracks, it becomes a focused monitoring tool instead of an expensive dashboard of numbers. If it points to something else entirely, you'll know before committing $300.
