Poor reliability
on January 12, 2026
Posted by: Mark J.

In less than a year the water pump module is no longer working. It first started to not recognize when it was filled, but was able to fix that by cleaning the contacts on the pump inside the module. A couple months later, the pump still recognizes when tank is filled but pump motor itself is shorted. I’ve always used filtered water from the refrigerator to fill the unit as well as clean the fill tank periodically to remove any scale. The wick has been replaced once as directed by the app. This is extremely disappointing, especially since no replacement parts are listed / available.
No, I would not recommend this to a friend.

Mostly fine

The humidistat is pretty useless, as you would expect since it’s right inside the unit pushing the moist air. If you ignore that and the auto feature it’s just fine.

Perfect!

My new apartment has been unbearably dry, and this humidifier has completely resolved the issue. No more snake skin and nose bleeds! It’s easy to operate and clean, and has been working like a dream. Best humidifier I’ve ever had (and I’ve owned a lot over the years).
I would recommend this to a friend!

Quiet easy to use

We have been using humidifier for about 2 weeks. It is so quiet, I was concerned at first that it wasn't working. The machine is easy to fill and clean. Being able to use tap water is a huge bonus!

This company sold me a faulty product

Basin is full and below the max line and yet the humidifier “low water” light comes on every time. I shouldn’t have to troubleshoot a brand new device every night before using. This product hasn’t worked the entire two weeks I’ve had it. I will never purchase another BlueAir item ever again, I believe this item didn’t pass QC (there’s no document to certify it did like with most small appliances) Oh and now my order can’t be found via the return system, how convenient....

I have tried humidifiers over the years both mist and mist free.Without exception the model H35i is far superior to any other humidifier I have ever used.It performs as the manufacturer claims.I would recommend it to anyone.

Good Humidifier
on December 25, 2025
Posted by: Marty M.

The humidifier does a good job of increasing the humidity in our bedroom. It’s easy to refill. My only complaint is the humidity % is off about 10% too high. I have a temp/humidity monitor in the bedroom that is generally correct. The temperature is off several degrees too low.

Disappointed
on December 23, 2025

As a satisfied user of two different Blueair air filters, I had high hopes for the highly-reviewed humidifiers. The good: The InvisibleMist units that I purchased came very quickly! They were not too hard to set up, and the mist is, indeed, invisible. It does not deposit white particles on anything, it is easy to refill, and it takes up only a little space.The disappointing: Even in a closed bedroom of less than 200 square feet, the unit has not been able to get the humidity above 40%, even on all of the highest settings (we are in the mid-Atlantic region, so not in a desert or extremely cold, dry climate). It seems to struggle to even keep the humidity in the 30% range. I can’t imagine it ever reaching the factory-preset 50%! The two units I bought are better than nothing—the water level goes down, so clearly they *are* operating—but I was expecting much, much better results based on the information provided on the website. Sadly, I cannot recommend.
