Mi Smart Antibacterial Humidifier Review [In-depth and UV-C lamp up close]

This is my in-depth review of the Xiaomi or Mi Smart Antibacterial Humidifier with built-in UV-C antibacterial system.
As usual, I wasn't able to find any reviews of this product from Filipino creators and I'm pretty sure a lot of you guys are looking for insights regarding this product so I took matters into my own hands!
I know that our climate is pretty humid already but it is a completely different story when your room is sealed and use an air conditioner 24/7, in this video I discussed the best things about having a humidifier for personal use and why you must get one even if you live in the tropics!
Product Features:
-Disperses cold mist into the air, which helps to humidify the air
-UV-C light source built into the water atomization base destroys bacteria in the water
-The 4.5 liter tank is sufficient for 12-15 hours of operation
-Individual settings (3 mist levels)
-Built-in humidity sensor
-Built-in WiFi control module
-Control via the Mi Home application
-Compatible with Google Assistant and Amazon Alexa
-Quiet operation, less than 38 dB
-25 watts
DISCLAIMER: As usual, I suck at video editing so I ask for your forgiveness! Haha!

best review ever! so detailed, love it :)

[@KevinSoRandom]

Thank you so much!

[@MrBojem3a]

If you’ve never used an air filter these are great. kzbin.infoUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!

It does make a sound but nothing too distracting though sometimes it’s louder than my AC since the AC is really quiet when maintaining temps nalang.

It's been working for maybe 2 hrs now. Is there something wrong with the valve or the thing that's supposed to push it from below?

I'm worried about the potential ozone byproduct from the UVC light, does it release a weird smell?

[@bitume]

Here's what I found on Quora: "Most do not, or do not with the UV lamps used. Unless the lamp produces UV- 215 or shorter wavelength, it cannot ionize oxygen and nitrogen to form ozone. Most UV lamps in these devices are UV-254 or even longer wavelength, which are "germicidal" or "advanced oxidation"."

[@twentytwo138]

@@bitume Thanks for the reply. Yes i asked Xiaomi if their UV bulb is above or below 240nm wavelength but they couldn't answer. They said: ''We don't have official information about ozone'' I think they should what kind of bulb they use. Also, most UVC bulbs have a coating inside that blocks shorter wavelengths, and if this coating wears off it can start leaking ozone. I have a UVC lamp with ozone and it's a fully clear bulb, it says on the package what wavelength is it (i forgot exactly but it's below 240nm) I will just have to trust Xiaomi and the technology, hopefully it's safe.

[@KevinSoRandom]

As far as I can tell, the UV light only works when it’s filling the reservoir with water then shuts off (as I’ve demonstrated in the video) so there’s very little chance for ozone to be produce plus the lamp is mostly submerged in water not the air. 😊
