Great
All around great. My only complaints centre around the app. There's no dark mode; no way to change to scaling for the graphs: the graph for temperature goes from -10°C (absurd) to 40°C, the one for humidity goes from 0% to 80%; they removed the ability to switch off the display in a recent update.

Finally!!! A good humidifier!
I've been desperate to find a good humidifier. Cold mist is not good because tap water spreads all kind of nasty stuff and using distilled water would be way too expensive, hot mist is not good for sensitive individuals (ex. eyes/nose/lungs issues) so it had to be an evaporative humidifier. Tried a couple but had to send the back. This is the real deal. Very quiet even at fan speed 2, easy to fill both from the tank and top as well, super easy to clean (just 2 pieces to dry). Only one small gotcha: the sensor to measure humidity is right on top where the humidity is being dispersed so the measurement is always kinda skewed (much more humid than it would be in the rest of the room). Besides that really nice!

Not recommended! Humidifier malfunctioned after few months.
Humidifier malfunctioned after 4-5 months. With a full tank, it's water indicator turns and and stopped running at all. Instructiosn to clean/fix on the website are inaccurate and not for this product.

Quality- love the ease of a ‘pour on the top’ access to add water (do not need to remove casing or tank. Part of choice was the NO Mist - evaporation technology so NO dripping of droplets in room or fine white dust - especially love the filters (can wash by hand) to eliminate air particles and and the wick technology limiting the chance of mold in tank/water/air - Quiet! Like the App control and on the canister manual controls. Set Humidity level / alerts for low water and filter cleaning or change required. Quality product - purchased for parents in nursing home- dry air hard on respiratory system and skin. Great price point / quick delivery / online order for filters (1-2 year) depending on use

Really worth it. It really humidifies the room without having a mist. That's what I needed. My humidifier is next to a closed plant cabinet and it increased the humidity in my room as well as in the closed plant cabinet. Thinking of purchasing another one for the living room. Above all there's no sound coming out of it and the fan is at level 2

UPDATE : 1 Month Later - It DIED! Dead as a doornail in a MONTH people! Will not turn on, if it does turn on, it shuts itself off, if it manages to be on and running, the water pump won’t bring water up onto the filter. I have thrown in the proverbial towel and returned it. DO NOT BUY THIS. PROS: Works brilliantly! I live in a desert and usual humidity was around 5 - 10%. I suffered from frequent nose bleeds, dry skin and dry eyes. This little unit has kept my bedroom at a very comfortable 45% humidity. I have to refill it daily, but that’s understandable! Refilling it is extremely easy with a water pitcher. I have not spilled anything. The unit is extremely quiet, and once I figured out I could adjust the brightness of the display on the app I think it is a perfect humidifier. I would absolutely plan on using the app if you purchase the device. The functionality of the top display is such that you really are better off using the app. It works seamlessly once you get the controls down. CONS: Keep in mind that when using the included QR code to “register” the device you’re only guided into signing up for the blue air promotional emails which is why I’ve knocked one star off. You’ll need to use the email associated with the app, create an account on their website, and then go to register the device under the “devices and warranty” subheading using the serial number found on the back of the unit and your date of purchase from Amazon to actually register your device for the 3 year extended warranty.
