The Awair Element is the standout solution: it turns CO2, PM2.5, VOC, temperature and humidity readings into a single Awair Score and links to your phone and smart home so you can actually fix the problem.

Best overall: Awair Element
Awair Element — £219.99
The Awair Element gives you clear, actionable indoor-air feedback fast: a single Awair Score for quick decisions and detailed CO2, VOC and PM2.5 data in the Awair Home app so you can test fixes (open a window, run a fan) and see results in real time. Our score: 8.1/10.
Why we picked it:
- Tracks the five metrics that matter (CO2, VOCs, PM2.5, temperature, humidity), so you won't miss a ventilation or pollution problem.
- Uses a laser/optical PM2.5 sensor plus a dedicated CO2 sensor, giving readings that line up with other consumer-grade monitors and react fast enough to show the effect of opening a window.
- Solid connectivity: Wi‑Fi/Bluetooth plus the Awair Home app for trends, alerts and smart‑home automations—useful if you want purifiers or fans to kick in automatically.
The trade-off: It needs a constant USB power plug and shows only a simple status light on the device—open the app for full numbers.
Buy it if you want sensible, real-time indoor-air feedback and automations to reduce CO2, VOCs or fine dust; skip it if you need a battery‑powered, portable monitor or a large, always‑on numeric display.

Best upgrade: IQAir AirVisual Pro
IQAir AirVisual Pro — £294
The premium buy here is a readable, on-device experience. The AirVisual Pro adds a large 5" colour display with clear numeric PM2.5 and CO2 values and ties into IQAir’s outdoor forecasts and station data—handy if you want to decide whether to ventilate based on outdoor pollution or track indoor numbers without your phone.
Worth it if: you need a large, always-on numeric display and outdoor‑air context to decide when to open windows or shut them.
Best budget pick: Amazon Smart Air Quality Monitor
Amazon Smart Air Quality Monitor — £69.99
At this price you get PM2.5 and VOC sensing, CO monitoring, and tight Alexa integration for voice alarms and routines. The device itself has only a colour LED for instant checks, but the Alexa app gives you the historic data. It’s the practical choice when you want automated alerts and routines without spending a lot.
Worth it if: you want straightforward Alexa alerts and automations to trigger purifiers or Echo announcements on a strict budget.
How we chose
We prioritised sensors (CO2, PM2.5, VOCs), sensor type (laser/optical PM, dedicated CO2), responsiveness, on‑device feedback, app quality and smart‑home integrations. Sources included manufacturer specs (Awair, IQAir), product reviews (The Verge), and community feedback on Reddit for real-world reliability.
Frequently asked questions
Do I actually need an indoor air-quality monitor? If you notice stuffy rooms, frequent headaches, allergies, or live near traffic or a wood‑burner, yes. A monitor tells you whether the issue is ventilation (CO2) or pollutants (PM2.5/VOCs), so you fix the right problem instead of guessing.
Is £219.99 for the Awair Element worth it? If you want dependable CO2 and PM2.5 readings plus app alerts and automations, yes—you’re paying for multi‑sensor coverage and smart‑home triggers rather than the cheapest possible PM sensor.
How do I maintain one of these monitors? Keep it plugged into clean air (avoid kitchens and direct drafts for baseline readings) and dust the intake occasionally; sensor drift is rare for consumer units, but expect to replace optical sensors or recalibrate after several years if accuracy becomes critical.
