VIVOSUN AeroStream H09 Intelligent Wi-Fi Humidifier, 2.38 Gal / 9 L Humidifier with Temp & Humidity Probe, Smart Remote Control, Designed for Growers

Works great. Adjustable mist. Super easy to set up. Quiet.

Hasn’t had any issues so far, perfect for tropical plants, set it to 90% and it will fog out a small room all day long, I don’t even hear it when it’s on, literally no noise at all. Just make sure to pipe it vertically so the water runs back into the unit so you don’t have water all over the ground from perspiration

One of the most versatile humidifiers I’ve seen in a while. Had issues with the probe registering on the screen, easily rectified (push till it clicks/ and it does). Accurate , responsive, and with a log function that allows you to see what the parameters are.. Can control the humidity a fairly large area , and temperature readouts all to your phone. Great mist output, QUIET, wi-fi adjustability of the parameters. And a two year warranty.

If you have dial-up internet and enjoy potential fire hazards, this is the humidifier for you! This is my third Aerostream humidifier. I previously owned the H05 and H09, so apparently I am a slow learner. My experience with the H05 should have been enough to make me run for the hills. After barely one season of careful use, it stopped producing mist properly. Instead of the mist traveling upward through the unit as it should, it was pooling inside the base. The base also became extremely hot during operation, which was concerning enough that I no longer felt comfortable using it. A humidifier that makes you wonder whether you should unplug it before calling the fire department is not exactly the kind of home appliance I’m looking for. And yet, against my better judgment, I bought another one, an "upgrade" to H09, whoo-hoo! Then another. Enter the Wi-Fi/Bluetooth circus. The connectivity simply does not work. I have jumped through every hoop imaginable: confirmed 2.4 GHz, changed my network security from modern WPA3 to WPA2, followed the troubleshooting instructions, and basically downgraded my home network to the technological equivalent of a rotary phone. Still. Nothing. Apparently, connecting this “smart” humidifier to Wi-Fi requires the networking skills of a NASA engineer and a willingness to resurrect technology from 2010. At this point, I have spent enough money and troubleshooting time on Aerostream humidifiers to earn an honorary degree in Why The Hell Won’t This Thing Connect? The irony is that the humidifier itself is supposed to make life easier. Instead, I’m troubleshooting Wi-Fi, worrying about water pooling in the base, and wondering why the appliance is getting hot enough to make me question my homeowners insurance. So let’s recap: H05: Stops producing mist, mist/pooling issue, gets extremely hot, potential fire hazard concerns. H09: Wi-Fi/Bluetooth connectivity is basically a decorative feature. Me: Apparently an idiot for buying a third one. These products are advertised as smart humidifiers with modern connectivity. My experience has been that they are JUST HUMIDIFIERS — and in the H05’s case, one I eventually didn’t feel safe using. After three Aerostream humidifiers, I am officially done. One star because zero stars apparently isn't an option.

The VIVOSUN AeroStream H19 Intelligent Environmental 19L Humidifier has been a fantastic addition to my setup. The large 19L capacity means I’m not constantly refilling it, and it runs for a surprisingly long time before needing attention. That alone makes it far more convenient than smaller humidifiers I’ve owned. The built-in temperature and humidity probe works really well and keeps the environment much more stable and consistent. I especially like the intelligent controls and the easy-to-use top control panel — everything is straightforward and responsive without feeling overly complicated. Mist output is strong, consistent, and adjustable, and the unit runs quieter than expected considering its size. It’s been great for maintaining proper humidity levels without constantly monitoring things manually. Build quality also feels solid and well thought out. Overall, this humidifier delivers excellent performance, smart automation, and convenience. Definitely worth it if you need a higher-capacity humidifier for a grow tent, larger room, or controlled environment setup.

Update: since my review, I read that the device sometimes overheats and needs to be fully turned off for 10-15 minutes to let it cool off. I tried that and it seems to have worked - the device responds to settings made in the App as expected. Bumping up to 4 stars. Original: I bought two of these 6, and 7 months ago respectively. They worked great at first, I have one that's just setup to run via the App, while the other is setup to run via a recipe on the Controller box that Vivosun provide. A couple of days ago, noticed the humidity in one of my tents was too low. Turns out: the humidifier just refuses to mist anymore. It will do it for a second or two when it starts up, then it will say it's misting but nothing happens, the water reservoir stays full. Even if I set target humidity to "100%", nothing happens. I also had a Vivosun AeroWave E6 fan crap out on me (the buttons on the top no longer work) and I'm starting to think that maybe Vivosun is not such a great brand when it comes to the electronic devices. Best stick to the "analog" items like tents or fabric pots.

Honestly it’s perfect other then the little bit of drip of water if the hose is tilted downwards but other then that keeps temps stables no connectivity issues & I’m on the move so mostly thru the app

This things great. You set it and forget it. Fill the tank every few days. My plants love it. I'm able to humidify a pretty large room with it

funktioniert einwandfrei und mit der App lässt sich das Gerät auch komfortabel fernsteuern. Der im Set enthaltene Thermo- und Luftfeuchtesensor liefert zuverlässige Daten. Immer nur destilliertes Wasser verwenden sonst verkalkt alles nach einiger Zeit. Der 5l-Tank hält bei einer 70% LF-Einstellung und 26°C im Growzelt (aussen LF 55%, 22°C) locker 1 Woche, bei höheren Temperaturen und LF-Einstellungen kann auch schon mal ein halber Tank in 2 Tagen weg sein.

Fonctionne très bien et de bonne qualité. Je recommande.

I’ve been using the AeroStream H09 for a few weeks now, and I’m honestly impressed. The mist output is consistent and adjustable, making it super easy to maintain perfect humidity levels for my plants. I especially love the automatic mode. it senses the room’s humidity and adjusts on its own, so I don’t have to constantly monitor it. The top-fill design is a huge plus. refilling the tank is quick, clean, and hassle-free, which makes daily use so much easier. Setup was straightforward, and the water tank is large enough that I only need to refill it every few days. The design is sleek and compact, so it fits nicely in my grow tent without taking up much space. My plants have noticeably perked up since I started using it — they’re happier, healthier, and the air just feels better overall. If you’re serious about maintaining optimal humidity, the AeroStream H09 is totally worth it. Definitely a five-star addition to my grow setup!

Stor tank. Bra styrning genom den externa givaren.
