If you’ve been wondering whether that nagging headache, restless sleep, or afternoon brain fog could be “something in the air,” Airthings is one of the most credible places to start. The Norway-born brand makes smart, consumer-friendly indoor air quality monitors—plus a thoughtfully designed air purifier—that track the invisible troublemakers in your home: radon, CO₂, PM2.5, VOCs, humidity, temperature, and more. In this in-depth Airthings review, I’ll explain what the brand does well, who it’s best for, and how its flagship devices differ in real-world use. You’ll also find hands-on impressions, a skimmable features section, and a practical buying guide so you can confidently pick the right model for your space.
Brand Snapshot
Airthings focuses on health-centric indoor air tech you can live with every day. The lineup spans Wi-Fi displays for always-on monitoring, compact Bluetooth sensors for bedrooms and utility spaces, and a quiet HEPA-13 air purifier that pairs with their monitors. Designed in Norway, the devices emphasize simplicity: e-ink screens you can read across the room, wave-to-check color glows, long battery life, and a free companion app with timelines, alerts, and tips. The ecosystem approach stands out—Airthings’ View-series monitors can act as a hub for Bluetooth Wave devices—so multi-room monitoring doesn’t mean juggling six different apps.
Customer-friendly policies are solid. Airthings highlights a 45-day money-back guarantee, a free 5-year extended warranty on consumer monitors with registration (standard coverage applies even if you don’t register), and an app that keeps adding features over time. The brand’s biggest differentiator is radon: unlike generic “air quality gadgets,” Airthings has built its reputation on trustworthy radon sensing and education—then layered the broader IAQ picture on top.
THE TOP FIVE
1) Airthings View Plus — The Flagship That Covers It All
If you only buy one Airthings device, make it View Plus. It’s the brand’s most comprehensive monitor, combining seven key sensors—radon, PM2.5, CO₂, VOCs, humidity, temperature, and air pressure—inside a Wi-Fi connected body with a crisp, low-power e-ink display. In a family room or kitchen, View Plus becomes your “air dashboard,” surfacing the issues that most affect daily life and long-term health. The glow ring offers instant green/yellow/red feedback; the display can be customized for the readings you care about most; and the app graphs changes over hours, days, and weeks so you can see whether opening a window, running exhaust, or tweaking HVAC actually helped.
Design is quietly premium: rounded edges, a matte front, and flexible power (battery or USB-C). Setup is painless; accuracy settles in after the usual VOC/CO₂ calibration period; and because it’s Wi-Fi, you can check readings away from home and get timely alerts. It also doubles as a hub for Wave devices when plugged in, so a single View Plus can bring bedroom or basement sensors online.
Price: $329.99
Best for: Whole-home air picture, families, smart-home tinkerers, anyone in a radon-prone region who also wants PM and CO₂ data.

2) Renew Air Purifier — A Quiet, Bedroom-Friendly HEPA That Plays Nice With Monitors
The Renew air purifier fills a gap: after you find a problem, you need a fix. Instead of a flashy tower with disco LEDs, Renew looks like Scandinavian furniture—flat-fronted, compact, and designed to disappear. Under the hood is a four-stage system: textile outer pre-filter (washable), washable inner pre-filter, HEPA-13 particle filter for 99.97% of 0.3µm particulates, and an activated charcoal stage for gases/odors. CADR is rated at 140 CFM, with excellent noise performance (down to 23 dB in Silent mode), and three modes (Auto, Boost, Silent).
What makes Renew feel smarter is the ecosystem angle. Use View Plus (or another monitor) to see particle spikes from cooking or wildfire smoke, then let Renew’s Auto mode do the cleanup. In a medium bedroom, air exchanges are brisk; in smaller spaces, it’s overkill in a good way. Filters are easy to handle, replacement packs are straightforward, and Wi-Fi control through the Airthings app keeps operation consistent with the monitors—open the app, see the problem, tap to boost.
Price: $399.99
Best for: Bedrooms and nurseries; people sensitive to PM2.5 and odors; anyone who prefers “quietly effective” over “look at me.”

3) Corentium Home 2 — A Smarter, Portable Radon Detector
If your main worry is radon, start with Corentium Home 2. It’s the updated take on the original, battery-powered digital radon detector that made Airthings famous. Now you also get Bluetooth app connectivity plus temperature and humidity sensors—smart additions for basements and ground-floor spaces where dampness and cold often travel with radon concerns. The simple LCD cycles through 24-hour, 7-day, 30-day, and long-term averages, and the app shows historical graphs and tailored guidance in plain language.
Because it runs on two AA batteries and needs no outlet, you can test multiple rooms over time, log results for real estate transactions, or verify that a mitigation system is doing its job. It’s not Wi-Fi, so remote checks require pairing with the app—or link it to a View-series hub device later if you want always-on access.
Price: $179.99
Best for: First radon tests, renters, homeowners validating mitigation, anyone who wants credible, easy-to-read long-term averages.

4) Wave Enhance — The Bedroom CO₂ & Sleep Clarity Tool
Sleep quality and CO₂ are tightly linked, and Wave Enhance leans into that reality. This palm-sized, battery-powered monitor focuses on the comfort-and-sleep cocktail: CO₂, VOCs, humidity, temperature, and air pressure, plus ambient noise and light. In practice, that means you can track whether stale air (rising CO₂), too-dry or too-humid conditions, a too-warm room, or nighttime noise is what’s sabotaging your rest. The daily Sleep Disruptors™ report in the app is genuinely helpful—less “mystery aura score,” more “here’s what changed and what to try tonight.”
Design details matter: there’s a built-in stand, wave-to-check glow feedback, and batteries that last months. It syncs over Bluetooth in-home; if you use a View device as a hub, you get remote access and richer automation. Paired with Renew and a cracked-open door (or a short pre-bedroom ventilation routine), many households see tangible sleep and concentration improvements within days.
Price: $159.99
Best for: Bedrooms, home offices, students, and anyone suspecting CO₂ or humidity swings are behind groggy mornings and afternoon slumps.

5) View Radon — Wi-Fi Radon Monitoring With a Room-Readable Display
For basements or ground-floor rooms where you want always-on radon visibility, View Radon is the connected choice. Think of it as the radon-specific sibling to View Plus: an e-ink display, Wi-Fi connectivity for remote checks and alerts, and three sensors—radon, humidity, temperature—tuned for long-term trends. Because the display is customizable and the glow light is color-coded, you’ll actually glance at it and act (ventilate, check seals, schedule mitigation) instead of forgetting there’s a monitor in the room.
On a shelf or wall, it blends into finished spaces better than most lab-style testers. And when plugged in, it can act as a hub for Wave devices—handy if your basement door separates a Bluetooth-only sensor from your router upstairs.
Price: $219.99
Best for: Homeowners who want Wi-Fi radon tracking and a readable display in the space where radon risk is highest.

Hands-On Impressions & Everyday Experience
Airthings gear earns trust by being boring—in the best way. Unbox, pop in batteries (or plug in via USB-C), add to the app, and let the sensors settle. Over the first week, VOC and CO₂ readings “find their baseline,” so don’t panic if day-one numbers wobble; the app explains what’s normal. The e-ink displays are a win for kitchens, hallways, and basements; you can read them at a glance without bathing your room in light. The wave-to-check glow makes it easy to get a quick “is anything off?” read as you pass by.
In a typical home, View Plus lives where family life happens (kitchen/living area), Wave Enhance claims the primary bedroom, and View Radon or Corentium Home 2 patrols the basement. If wildfire smoke rolls through, PM2.5 will spike first; Renew’s Auto mode and a well-timed window open bring it down quickly. If headaches cluster on WFH days, you’ll often spot sustained CO₂ above ~1,000 ppm in a closed office—cracking the door or adding a ventilation burst before meetings is an instant fix.
The app is a strong partner: graphs are clean, alerts are timely instead of naggy, and the tips are written like a coach, not a chemistry textbook. Smart-home integrations (IFTTT, Alexa, Google Assistant, Homey) are available, with the most utility coming from automations: “If PM2.5 > X, boost Renew,” or “If CO₂ > 1,000 ppm in bedroom, remind me to ventilate.” The broader story is empowerment: readings become habits—ventilate after cooking, dehumidify the laundry room, crack the door at night, replace the range hood filter—and quality of life improves.

Quality, Reliability & Support
Airthings’ credibility springs from years of radon specialization and transparent specs. The devices use appropriate sensing technologies (e.g., NDIR for CO₂, laser scattering for PM2.5, alpha spectrometry for radon) and provide realistic accuracy ranges alongside sensible thresholds. Build quality is solid—no rattly plastics, intuitive mounting, and battery compartments that don’t make you swear. The company backs products with a standard warranty and invites consumers to extend coverage to five years (free) with a simple registration. If you’re the documentation type, data sheets and manuals are easy to find, and support channels respond in plain English.
Pricing & Value for Money
Airthings sits in the “serious consumer” tier: not cheap novelty gadgets, but also not enterprise-priced. The value equation is strong because the monitors help you act—ventilate, purify, dehumidify—so you feel better and protect your home. With verified pricing on the five spotlighted products—View Plus ($329.99), Renew ($399.99), Corentium Home 2 ($179.99), Wave Enhance ($159.99), and View Radon ($219.99)—you can cover a small home’s key spaces for less than many “smart” appliances that never pay you back in sleep, focus, or peace of mind.
Who It’s Best For / Who Should Skip It
Best for:
- Health-conscious families, allergy/asthma households, and anyone in a radon-prone area.
- Remote workers and students who need daytime focus and nighttime recovery.
- DIYers who want to measure, then improve—and see the impact in data.
- Renters who need portable, battery-powered monitoring without drilling holes or rewiring.
Might skip:
- Minimalists who don’t want another app (though the e-ink displays help).
- Shoppers who just want a cheap “air gadget” with vague bar charts and no radon; Airthings is overkill for that use case.
- People seeking Apple HomeKit or SmartThings native support right now; consider IFTTT/Homey bridges instead.
Comparisons (Choosing Between Airthings Models)
- View Plus vs. View Radon: If air quality beyond radon matters (PM2.5, CO₂, VOCs), View Plus is the no-brainer main monitor. If you already have a general monitor upstairs and want always-on radon downstairs, View Radon is simpler and less expensive, with the display you’ll actually check in a basement.
- Corentium Home 2 vs. View Radon: Both track radon reliably. Corentium is portable and battery-only with a simple LCD—great for rotating between rooms or documenting readings for a sale. View Radon adds Wi-Fi and a customizable e-ink display for set-and-forget, always-on coverage in a fixed spot.
- Wave Enhance vs. View Plus: If your priority is sleep and CO₂ in a bedroom or a small office, Wave Enhance gives targeted insights (including ambient noise & light) at a lower entry price. For a single device that covers the whole IAQ picture, choose View Plus.
Buying Guide: How to Pick the Right Airthings Setup
- Map your risks and routines. Basement or ground level? Prioritize radon (View Radon or Corentium Home 2). Cooking daily or in wildfire-prone regions? Make PM2.5 visible (View Plus) and pair with Renew.
- Start with one anchor monitor. Place View Plus in the main living area where it can act as your hub and show you the broadest issues.
- Target bedrooms for CO₂. Add Wave Enhance where sleep and focus matter. If you frequently wake up groggy, you need CO₂ visibility.
- Use data to fix, not fret. When readings go yellow/red, ventilate or purify. If humidity trends high in laundry/bath, consider Wave Mini (or a dehumidifier) and improve airflow.
- Mind sensor settling. Expect a few days to a week for VOC/CO₂ to stabilize. Look at trends, not single peaks.
- Automate the obvious. If PM2.5 rises, boost Renew. If CO₂ crosses 1,000 ppm in a bedroom, remind yourself to crack the door.
- Register for extended coverage. Claim the free 5-year extended warranty on consumer monitors and keep receipts organized.
FAQs
Do I need Wi-Fi for every monitor?
No. Wave-series devices use Bluetooth for in-home sync. A View-series monitor can act as a hub when plugged in, bringing Bluetooth devices online for remote access and alerts.
How often do I need to replace filters in Renew?
The textile pre-filter and inner pre-filter are washable; the HEPA-13 and charcoal filters are replaceable. The app will nudge you based on usage, but a few months is typical depending on air quality and run time.
How long until readings are “trustworthy”?
PM, temperature, and humidity are useful immediately. VOC and CO₂ sensors generally need several days to settle. Airthings’ app guides you through what’s normal in week one.
Can I export data or view it on desktop?
Yes. The app and web dashboard show historical graphs; advanced users can dig deeper via the dashboard for multi-room trends.
What’s the warranty and return situation?
Airthings offers standard warranty coverage and highlights a free 5-year extended warranty on consumer monitors when you register shortly after purchase. A 45-day money-back guarantee is also promoted for peace of mind.
Is there voice assistant support?
Yes. Airthings supports Alexa and Google Assistant for basic queries, plus IFTTT and Homey for automation. For now, plan on those paths if you want routines.
Where should I place a radon monitor?
Use basements and ground-floor living areas first, away from vents, windows, and exterior doors. Focus on long-term averages rather than momentary spikes.
Verdict
Airthings earns a strong recommendation for households that want to understand and improve their indoor air, not just peek at a vague AQI. The hardware is thoughtfully designed, the sensing tech is credible, and the app strikes the right balance of clarity and depth. Start with View Plus as your anchor, add Wave Enhance where you sleep or work, use View Radon or Corentium Home 2 for targeted radon vigilance, and let Renew do the quiet cleanup. You’ll breathe easier—and you’ll know why.
