Best humidifier I’ve owned!

The InvisibleMist H35i is a perfect solution for my needs (keeping musical instruments in their “happy zone” without white dust everywhere). Highly recommended!
I would recommend this to a friend!

Trash

I purchased this unit one year and one week ago. Just a few short hours outside of the warranty it stopped working. The unit reported no water when the tank was full. After completing all the troubleshooting tips, it still wouldn’t work. It’s frustrating when something fails immediately after the end of the warranty although that seems to be happening more frequently with products nowadays. I would not recommend Blueair products; there are other manufacturers out there with a better reputation for reliability.

Did not last a year

Worked great for a while, easy to fill that was the positive when I bouth it. Didn't last a year and it is expensive I troubleshoot but the % indicator didn't work, then the empty indicator kept coming up and stopped the fan. I replaced the filter , paid direct to Blueair and still nothing works.

New Design - I like it
on March 12, 2026
Posted by: A s. c.

I have both the old and new design of this InvisibleMistTM Humidifier and I must say I really like the new one, The top and bottom lock together and that makes it just about impossible to spill anything and the filter housing pops together with nothing to unscrew and get stuck. It may be my imagination but it seems that it humidifies the room air a lot faster as well. Good Job Blueair - I'm a happy customer

Too much maintenance
on February 22, 2026
Posted by: Ben S.

I bought this thinking it was low maintenance. Having to clean the tank, the pump, and the wick filter weekly is pretty inconvenient. The performance of the product is fine, but I still regret purchasing it.

Not powerful enough
on February 14, 2026
Posted by: John D.
from US, United States
My apartment is about 400 square feet and the humidifier can't keep up unfortunately. It runs full blast, very loud, and can only add a percent or two to humidity
No, I would not recommend this to a friend.

sophisticated humidifier
on February 11, 2026
Posted by: Jeff L.
from US, United States
i was a little worried about connecting yet another appliance to WiFi, but I do love being able to modify settings without actually being in the room. I love the precision and the 2 hour drying time, and also the ability to know (based on location data) what outside humidity and temperature are.
I would recommend this to a friend!
