As someone who has bronchitis, I hate dry air. And I hate wasting money on products that promise relief but don’t deliver.
So when winter hit and my breathing started getting worse inside my own flat, I knew I had to do something. The air felt dry, heavy, and irritating — the kind that triggers coughing, congestion, and endless restless nights. I started searching for a real solution, but most of what I found looked like cheap plastic humidifiers that barely made a difference.
Then I kept seeing Clairu everywhere.
Over 37,900 people were talking about how it transformed dry, stuffy rooms into fresh, breathable spaces. Many of them had allergies, asthma, or breathing issues just like me — finally able to sleep through the night without waking up congested.
What really caught my attention was this: studies show that the right humidity levels can reduce airborne allergens by up to 30% — and Clairu is designed to reach those optimal levels in just 2 hours.
So I decided to put it to the test.
I ordered Clairu and compared it against four other popular humidifiers, using them in the same room under the same conditions. My goal was simple: find out which one actually made the air easier to breathe.
Spoiler: most of them didn’t make it past day three.
My Test Results
First up: setup. I wanted to see if Clairu was really as simple as they claim.
I took it out of the box, filled the tank with water, plugged it in, and tapped the power button. That was it. No complicated filters, no messy hoses, no long instruction manual to figure out. From box to mist took less than two minutes — faster than making a cup of tea.
The other humidifiers I tested came with multi-part lids, awkward water trays, and confusing control panels. Clairu skipped all of that. One touch and it was already running.
Next came the humidity and breathing test.
I let my bedroom air get dry and stuffy the way it usually does at night. My throat felt scratchy, my nose slightly blocked — the exact feeling that triggers my bronchitis. Then I turned Clairu on at full mist.
Within three minutes, I could feel the difference. The air went from sharp and dry to soft and breathable. After about 20 minutes, my congestion started easing, my breathing felt smoother, and that tight feeling in my chest was noticeably reduced.
This wasn’t just air moving around. Clairu was actually changing the moisture level of the room — and I could feel it with every breath.
The competing models barely produced visible mist, even after running for half an hour.
Then I tested mist quality and coverage.
Clairu’s ultrasonic mist was ultra-fine and evenly distributed. Instead of leaving wet spots on furniture or fogging up one corner of the room, the moisture spread throughout the space. My skin felt less tight, my eyes stopped feeling dry, and my sinuses stayed clear all night.
I even added a few drops of essential oil, and the scent was light, clean, and natural — not overpowering or artificial.
Next was noise.
I ran Clairu overnight in all its modes. On low, it was practically silent. No buzzing, no gurgling, no annoying humming. I slept through the night without being woken up once — which, for someone with breathing issues, is rare.
Even at higher mist levels, it stayed quieter than my ceiling fan.
Then I tested timers and daily use.
I used the 2-hour setting during the day when my room felt dry, the 4-hour mode in the evening, and the 6-hour timer at night. It shut itself off every time exactly when it was supposed to. No wasted water, no overheating, no worries about leaving it on while I slept.
Now for something important to me: safety for pets.
I have a cat, and I’m extremely careful about anything I run in my home. Clairu stayed cool to the touch, stable on surfaces, and produced no heat or fumes. Even better — the added humidity actually helped my cat breathe more comfortably. His sneezing went down, and the air felt healthier for both of us.
No other unit I tested felt this safe to run all day and all night.
Results:
After testing five different humidifiers, Clairu was the only one that actually solved the problem I had — dry air, congestion, poor sleep, and irritated breathing.
The others either produced weak mist, made noise, or felt unsafe to leave running.
Clairu delivered real relief, night after night — without any hassle.
Value
Most portable humidifiers cost around $250, and many of them still struggle to properly humidify a single room. On top of that, inefficient models burn through electricity and require constant refills, which adds up over time.
Clairu costs less upfront and runs far more efficiently, giving you clean, properly balanced air without inflating your energy bill — even when you use it every day.
Right now, Clairu is $79.99 with 50% off. If you buy three, the price drops to just $49.99 each for a total of $149.97 — that’s 60% off.
I bought three myself. One stays in my bedroom to help me breathe better at night. One stays near where my cat sleeps, so he gets the same clean, moisturized air. And the third moves between my office and living room, wherever the air feels driest.
At $49.99 per unit, I paid less for all three than what most people pay for one overpriced humidifier — and I didn’t have to deal with bulky machines, loud fans, or complicated maintenance. For the level of comfort, breathing relief, and air quality it delivers, Clairu is easily the best value I tested.
Stay Comfortable & Save Big
Clairu gives you year-round comfort without the usual hassles. There’s no installation, no filters to replace, no bulky machines, and no need to buy separate devices for different seasons.
Using advanced ultrasonic mist technology, Clairu keeps your home at the perfect humidity level all year long — whether the air is dry from winter heating or from summer air conditioning.
And Clairu doesn’t just fix dry air — it transforms the entire atmosphere of your room.
With one compact device, you get:
No need for two machines. No complicated setup. Just plug it in, add a few drops of essential oil, choose your light, and your space becomes a calm, soothing sanctuary.
Best of all, Clairu runs energy-efficiently, so you can use it every day without worrying about your electricity bill creeping up. You get comfort that moves with you, costs less to run, and works every single season — so your air stays fresh, moist, and healthy all year round.
Thousands of Happy Customers
I’ve struggled with asthma for years, especially in winter when the air gets painfully dry. After just two nights with Clairu, my chest felt lighter and I stopped waking up coughing. I honestly didn’t expect such a big difference.
My heating dries the air out like crazy and I used to get so congested and wake up with headaches every morning. With Clairu I sleep like a baby without headache or dry nose.
My daughter’s room gets so dry with the heat on and she kept waking up coughing. Started running this thing and she’s actually sleepin better now 🙌 plus its not loud or annoying so we’re good
I constantly had a sore throat in the mornings. I thought it was allergies, but it was actually dry air. Clairu fixed it. I wake up without that burning, scratchy feeling now.
My eczema flares up whenever the air is dry. Since using Clairu, my skin is calmer, less red, and far less itchy. I didn’t expect a humidifier to help this much.
I have asthma and a cat, so air quality is important to me. Clairu made the air feel noticeably cleaner and more humid. Both of us are breathing easier now.
Purchase and Delivery Process
Ordering Clairu was simple. Since they sell exclusively online, you get factory-direct pricing without retail markups.
I placed my order on a Tuesday and had it delivered by Friday. My units arrived well-packaged in protective foam, ready to plug in and use immediately.
The 60% discount was automatically applied at checkout. I didn’t have to hunt for promo codes or jump through promotional hoops.
If you’re thinking about getting multiple units for different rooms or want one for a second property, the bundle deals make sense. The more units you order, the lower the per-unit price drops. I went with three and saved an additional 10% on top of the base discount.

#1 Portable Humidifier in 2026
After testing dozens of humidifiers, Clairu stood out for one simple reason: it actually does what it promises.
It quickly restores healthy humidity levels in dry rooms, improves air quality by reducing airborne allergens, and runs quietly enough to use all night without disturbance. Most humidifiers fail at least one of these. Clairu delivers on all three — while using very little energy.
That’s why it takes the #1 spot.
