Unit ok but lacking Alexa Integration!

Love the actual humidifier unit. App is ok but ... without Alexa integration it will only be sub par! Alexa unfortunately is a standard for any Smarthome.

Excellent Humidifier

Blueair H35i Humidifier performance is excellent! Very easy to clean, maintain and provides a user prompt when the wick needs to be replaced. I would recommend Blueair products that have been engineered to provide healthy air and minimal maintenance.
I would recommend this to a friend!

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!

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

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.
