Good machine, poor instructions
on December 16, 2025

Machine works well, but slowly. App is nice. Blueair should make it clear what the different settings do. Manual is very sparse on that. Manual is very sparse on everything, making understanding the machine difficult. Even registering for the extended warranty was very painful and time consuming. You can do much better than that.
I would recommend this to a friend!

Easy and convenient humidifier

This is a simple and well made product that really works. The Blueair invivible mist humidifier is quiet and improves the moisture level in our home to a comfortable adjustable level in winter. I am probably going to purchase a second unit.

Love it! It is so easy to refill and runs quiet. I love that you can program it to dim the lights at night.

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.
No, I would not recommend this to a friend.

Good Humidifier
on December 25, 2025

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.

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.

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!

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.
