Airthings Wave Plus — 6-Sensor Indoor Air Quality + Radon Monitor

The smart indoor air monitor that does radon too

The Airthings Wave Plus is Airthings' six-sensor smart air monitor — the one that catches radon and the five other things that affect how you actually feel in your house: CO2 buildup, VOC chemicals, humidity swings, temperature drift, and atmospheric pressure. Battery-powered, app-controlled, wall-mountable.

Six sensors in one device

• Radon — short-term + long-term averages, alerts above Health Canada's 200 Bq/m³ guideline
• CO2 — detects stuffy rooms and over-occupied spaces (bedrooms, home offices)
• TVOCs — volatile organic compounds from cleaning products, off-gassing, cooking
• Humidity — mould-risk warnings above 60% RH and dry-air warnings below 30%
• Temperature — room-by-room thermal mapping when you deploy multiples
• Barometric pressure — useful for radon analysis (low pressure pulls more radon from soil)

Best for

• Homeowners who want one device covering radon + indoor air, not two
• Post-mitigation verification — confirms your SSD system is keeping radon below 200 Bq/m³ long-term
• New-construction monitoring — tracks VOC off-gassing from new floors / cabinetry / furniture
• Bedrooms — CO2 + radon together catch the two big sleep-quality factors
