When it comes to performance the Xiaomi Sterilizer lamp is pretty damn amazing. Although it took me a while to get used to the remote usage. I can certainly say with complete confidence that it's probably one of the best UV lamps in the market when it comes to both real-time and long term performance. I've used it for almost 6 months now and the bulb or the device as a whole hasn't run into any problems.

Although the build has degraded bit, it has weathered all kinds of storms. I pretty much use it up to five times on an average every day. It is highly effective, using a standard voltage of 220B this lamp can obliterate all microbes in a 20-30 meter radius. Additionally, it can be used consecutively without any issues.

Overall, it's definitely a great device. However, the IoT tech can be a pro and con. If your your Mijia app isn't update of your hooked up to the lamp through an unstable connection. This lamp tends to lag. There was a time when I walked in thinking it wasn't working when it suddenly lit up. The sensors are not omnipotent. So, you should be quite careful.

Xiaomi Sterilizer Lamp Review - Final Thoughts

Xiaomi specifically launched this product through their crowdfunding platform to combat against the pandemic and harmful microbes in general. The Xiaomi Sterilizer lamp is powerful enough to kill microbes in all corners of a closed room like a toilet where there's no air circulation. By using this device, you can certainly protect yourself to a certain degree. It's at least better than doing nothing at all. So yes, the Xiaomi UV Lamp is well worth it.

Not only does the Xiaomi Sterilization Lamp help disinfect microbes effectively it's also extremely affordable. It is simple in its functionality. It only emits UV light. However, since it's a Xiaomi product, it can be hooked up to the IoT ecosystem and control via your phone. This basically means that you can control the device from a different room. With all the features and the current state of affairs, it's a product that not just worth it but it's a Xiaomi product that's a must-have.

Does the Xiaomi Steilizer Lamp Emit Ozone?

Since the Xiaomi Sterilizer is a UV lamp it does emit a bit of ozone. So, much so that you can occasionally smell it. Now, this tough. The emission of ozone basically, means it is effective and it's actually disinfecting the room. However, it is quite harmful to the environment and the human body.

I would honestly recommend using this device as and when you actually need. For example, after a bunch of people visit your house for example. And I would also recommend you leave the room for about an hour after you disinfect it. Don't enter the room immediately after you disinfect it. So, be as careful and as responsible as possible. It is an extremely useful product that can potentially save you from harm. check out our Xiaomi Sterilizer Lamp Review for more details.

Xiaomi UV Sterilizer Lamp vs Xiaomi UV Sterilizer Box

Although both these products seem to cater to the same problem, it's quite different. The Sterilizer box is meant to sterilize small objects such as smart phones, makeup kits and other small items. This is good for sanitizing the products in your house.

The Xiaomi Sterilizer Lamp on the other hand is meant to sterilize the environment. During the Covid-19 crisis, hospitals across the world used UV Robot sterilisers to kill the bacteria in the rooms. With a sterilizer lamp, the room gets clean. It's best to keep the sterilizer lamp at the entrance to kill the bacteria in the air around it.
