Review of Oittm Smart Humidifier (Works With Amazon Alexa & Google Home)

Krzysztof is a lifelong future tech junkie investigating the latest stories from companies like Apple, Samsung, Google, and Amazon.


What's a Smart Humidifier?

Oittm's Smart Humidifier ($59.99) is a massive diffuser and humidifier that can help you sleep comfortably without having to lift a finger.

It has a 3L tank capacity with 250 ml/h of mist, and it can be programmed through the Smart Life app or with the Alexa and Google voice assistants.

This is one of the best humidifiers I've had the chance to test out, and by the end of this review, I guarantee that you'll be begging to buy this product.

How to Set Up Smart Humidifier

Setting up this product is a breeze; just follow these simple steps and you'll be on your way to a soothing experience.

  1. Remove the gray lid and check to see if the atomization tool is inside the water filter.
  2. If it's not there, place the atomization tool inside the filter (the "up" label on the tool should be facing towards you).
  3. Attach the tank cone to the filter by turning clockwise until it's tight.
  4. Fill the tank to just below the max line.
  5. Place the filter inside the tank and make sure the cone properly locks-in at the top of the tank.
  6. Cover with the gray lid.

More detailed instructions on how to set up the device, pics included, are in the user manual.

Note: Never fill above the max line and only pour water in/out the opposite side of the air passage (location of the max line).

How to Use With App

Please follow these instructions to set up the app control features.

  1. Download the Smart Life app from the Google Play or Apple Store.
  2. Enter your registration information if you haven't already.
  3. Locate and tap the humidifier option in "select device type" section.
  4. Hold the WiFi button on the humidifier (5 seconds) until the light starts to blink rapidly and hit the confirm selection in the app.
  5. Enter your WiFi information then wait until the device connects to your router, and tap complete to finish.

Once your device is connected, you'll be able to turn it on/off, change mist levels, and create schedules.

Note: If you're having trouble connecting your humidifier to Wi-Fi, then restart the process and try again. Make sure your product is located near your router during setup.

Best Features

Below are some of my favorite features, but please note that there were many more that I didn't include.

5 Best Features

  • Quiet Ultrasonic Technology
  • App/Voice Controls
  • 3L Water Capacity w/250 ml/h Mist Volume
  • Create Schedules
  • Can Add Essential Oils

Quiet Ultrasonic Technology

The first thing you'll notice when you turn it on is that it's super quiet. The hushed settings make it ideal for any room, including your child's bedroom.

Honestly I was surprised by how silent it was given its enormous capacity, though there was one thing that did annoy me, which I'll elaborate on in the "worst features" section.

App/Voice Controls

I don't think I've ever asked for a smart humidifier, but suddenly it doesn't seem like a strange idea.

Let's say you have it located far away and you want to turn it on, well what better way to do that than pull up your phone and turn it on from there. Better yet, why not pair it with Alexa or Google and command them to turn it on or off for you, pending you have them of course.

And yes, these methods do sound lazy, but they're equally as convenient.

3L Water Capacity w/250 ml/h Mist Water Volume

This is a huge, durable water tank, and it makes my other diffusers look like teacups.

The 3-liter capacity is massive, and with 250 ml/h of mist volume, it'll spray water for over 12 hours. With such bulk, you'll never have to worry about nonstop refilling again.

Also don't forget that you can prolong the length by choosing the lower tier mist settings (high, medium, low), which are excellent when you're away from home or at work.

Create Schedules

Yes, you can pick and choose when and what days you'd like the humidifier to go on or off.

Scheduling allows you to be in control, save money on electric bills, and invigorate your home at the right time. And because the spray can last as long as 20 hours, you won't have to worry that it'll stop working.

Can Add Essential Oils

It's listed as an essential oil diffuser, which means you can add oils to the water and freshen up your space.

Unfortunately, it'll take several drops to get the full effects because after all, it is a 3L tank, but you don't want to go overboard either as too many oils may stain your filter and/or tank.

Per their product page and through my own testing, the optimal amount of drops per tank is six though it may vary depending on the concentration of the aromas.

Worst Features

I wish I didn't have to mention these, but sadly there were some negatives that myself and other customers noticed while using the humidifier.

4 Worst Features

  • Loud Beeps With Input
  • LEDs Can't Be Turned Off
  • Water Can Only Be Poured Out on One Side
  • A lot of Leftover Water

Loud Beeps With Input

The humidifier is quiet but the beeps are not.

And regrettably you'll be hearing them a lot as all the buttons contain an obnoxious "beep" sound when pressed, and the same goes for app/voice controls.

To me it doesn't make any sense, why have an ultrasonic product that produces these high volume sounds. Oh well, at least the actual humidifier does stay quiet just as long as I leave it alone.

LEDs Can't Be Turned Off

This is a pro and con for me. The Oittm humidifier contains two sets of LED lights for the bottom control panel and near the top of the tank. There's even an LED button for day/night modes, and they can change colors.

All of this is great and all, but sometimes I wish they could be turned off. Now they aren't a huge distraction, but they're very noticeable at night. Maybe the next version or a software update will help clean this up.

Water Can Only Be Poured Out on One Side

I'm pretty sure I mentioned this above, but please be aware that water can only be poured opposite the air passage side.

Apparently that's because pouring water out from the wrong side will cause a leakage and burn the humidifier, which sounds like a pretty big flaw.

I don't like having to be this careful when emptying the container because I know one day I'll forget to pour it out correctly. This was a significant customer complaint that definitely needs to be fixed if they make another one.

A lot of Leftover Water

Here's another positive and negative complaint.

For the positive, the smart humidifier will immediately shut off when the water level is too low. In fact you'll even get a "water shortage" reminder on your phone, which is excellent if you're away from home and need to know what's going on.

Sadly, when you do come home, you may discover that the tank is nowhere close to being empty, which does negate the large capacity a bit.

For a tank so huge, you'd think it would use up as much water as possible, but alas that's not the case. So if you don't like wasting water, then maybe this isn't the humidifier for you.

How It Compares to Other Products

There are many kinds of diffusers and humidifiers on Amazon with both Wi-Fi and non-Wi-Fi variants, but I really wanted to focus on Oittm's other version for a moment.

The Oittm Smart Aroma Essential Oil Diffuser ($48.99) immediately caught my attention because of its elegant design and smart abilities.

Unlike the larger humidifier, this one is definitely geared towards exuding different aromas from essential oils. Granted it still has the LED's on top, the mist functionality, and all the voice and app controls of its larger relative, but it's a lot more pleasing to look at.

The size is also perfect for any room, and it's a cheaper, sleeker alternative to the product I'm currently reviewing.

I'll look into it more in the future and provide a better detailed assessment once I know what I'm dealing with.

Final Review

Despite the flaws, I was still more than happy with this product, though we'll see how it performs three to six months from now.

I would give the Oittm Smart Humidifier & Diffuser 4 out of 5 stars.

The water capacity is excellent, the smart controls were really cool, and it got the job done.

I didn't even mention how extremely well crafted the product is or that it includes a lift handle for easy room to room transport.

As for the cons, none of them were deal breakers, you just have to be extra careful when emptying/filling it. Over time you'll get used to the beeps, the leftover water won't kill you, and the LED's aren't a major distraction.

So all-in-all I had a great time testing this product, and I highly recommend it if you're looking for a long-lasting, durable, and high-tech humidifier.

Yeah those LEDs can get quite distracting as you've described. I don't mind the LEDs as much with this item, and the other features are overwhelmingly positive. So far it's my favorite product that I've reviewed.

Krzysztof Willman (author) from Parlin, New Jersey on August 18, 2018:

That's a really good point, I'll have to look into it, but I'm sure there are more advanced humidifiers that do this. Thank you for the info.

Liz Westwood from UK on August 14, 2018:

This is a very thorough and honest evaluation. I was interested in your comment about the LEDs. One of my gripes with hotel rooms is the amount of light pollution at night from LEDs. Although I could do with a smart dehumidifier, your review of this humidifier is very tempting.

FlourishAnyway from USA on August 13, 2018:

It would sure be great if these devices sensed that the room’s air was too dry and either cut on automatically or alerted you so you could make the judgment. Maybe some of them already do that?
