Kaiterra Laser Egg In-Depth Review

Kaiterra Laser Egg

With both outdoor and indoor air pollution becoming a greater issue daily, it’s important to be informed. 

While the AQI is a great reading that allows you to monitor the air quality outdoors, it’s often more difficult, or impossible, to get more specific readings. 

For example, considering how dangerous indoor air pollution is, how can you monitor it and make sure that you and your family are staying safe?

Luckily, there are some products which have been created to fit this gap. Whether you are looking to monitor the air pollution yourself, or to make sure you are breathing safe air indoors, the Kaiterra Laser Egg can help you.

Wondering about how indoor air pollution impacts us? I recently covered the impacts of air pollution on studying & academic performance.

I received a free review product from Kaiterra. However, the views and opinions expressed in this article are my honest thoughts on the product. I will never recommend a product that I believe is bad.


Why Get a Pollution Monitor?

Health Effects of Indoor Air Pollution

Health effects of indoor air pollution. Our World in Data, sourced from WHO.

With air pollution on the rise in many areas of the world, and with the health dangers that it brings,  it’s important that we can make sure that we are breathing safe air.

This doesn’t only apply outdoors, but also inside. In fact, indoor air pollution is commonly significantly worse than that which is found outdoors. Couple this with the fact that many people spend as much as 90% of their time indoors, and it’s vital to make sure that the air we are breathing is safe (EPA).

It is for this reason that an air pollution monitor is useful. Although we often pass off air pollution as someone else’s problem, it affects all of us, and it’s something that we need to be aware of.

This is where the Kaiterra Laser Egg comes in. 


What Is the Laser Egg?

Laser Egg Chemical

Laser Egg + Chemical

The Laser Egg is an air pollution monitor that monitors not only the fine dust particles (such as PM2.5) in the local air, but also the temperature, humidity, the VOCs (on Laser Egg+ Chemical), and indoor CO2 (on Laser Egg+ CO2). In other words, it’s an all-round air quality monitor. 

The Laser egg is relatively small and can be handheld. However, due to the sensors inside, it is also quite heavy. The shape of the product is an oval cut in half (think of an egg that has been cut through the middle).

The flat face of the egg has an LCD screen which reports the air quality as well as the temperature. If preferred, it can also be set to show the weather forecast or humidity. However, the screen is not the main way you will be checking the air quality. 

This is because the Laser Egg is very connected. It connects to 2.4ghz WiFi and can be accessed through a dedicated app. What makes the egg stand out however, is the compatibility with Apple Homekit and IFTTT. 

This means that automation tasks can be managed. For example, I use an iPhone and I decided to purchase a Homekit compatible power socket. I plugged in the dehumidifier through this socket. Whenever the Laser Egg detects a humidity level higher than my chosen level, the dehumidifier automatically turns on!

The possibilities are almost limitless, and I believe this will be one of the biggest appeals of the Laser Egg to many people. 

Finally, the laser egg also contains a battery. While the egg is a bit big for me to see it being comfortable to carry around, it is nice to be able to know that it’s portable when needed. This is especially nice if you usually have it docked in one room, but need to temporarily move it to manage VOCs (for example, if you are painting a room or cleaning).

The Laser Egg models all look the same. Only the colour of the border (in this image, blue) change. (Note: we use the color to mark different models, silver = Laser Egg, gold = Laser Egg+ Chemical, blue = Laser Egg+ CO2).

The Laser Egg is the standard model that Kaiterra offers. This egg is capable of measuring PM2.5 fine particles as well as offering other weather measurements such as the temperature, humidity, and will also show a weather forecast. 

This is the best model for people who are interested in managing the fine dust levels, but who don’t need to measure chemical levels.

Laser Egg + Chemical

The Laser Egg + Chemical is capable of everything that the standard Laser Egg is as well as measuring VOCs. VOCs are gases which can be found in the air all around us. These gases range widely, as do their effects on our health. 

This is my recommended model for anyone wanting to monitor their indoor air pollution. VOCs are often one of the most harmful aspects of air pollution, especially when indoors.

Laser Egg + CO2

The Laser Egg + CO2 is the third and final model of the Laser Egg. This egg is capable of everything that the standard model is and, on top of that, it also measures CO2. 

CO2 is gas that can be potentially harmful in high concentrations and it has been proven to lead to lower cognitive functions. Although this may not seem significant, a Harvard study found that a green space (reduced CO2) can lead to as much as double the scores by users on a test (Harvard).

Functionality & Accuracy 

Laser Egg Desk Setup

The Laser Egg is accurate for reporting indoor VOCs.

I personally used the Laser Egg + Chemical and I was pleasantly surprised by how accurate it appears to be. I tested it near a local air quality monitor in my neighbourhood (in Seoul) and the reading was within 5 AQI of the official air monitor. 

I have also noticed that it quickly reacts and updates. Although I don’t know the exact speed, it seems to update every few seconds. It reacted very quickly when I lit a candle, and also when I opened a bottle of nail polish next to it.

At one point it jumped to 500 (the highest level it records) and I thought that it may be faulty. However, it turned out to be caused by a bit of food that had fallen under a pot on the stove. This piece had burned, and the Laser Egg quickly reacted. As soon as the stove cooled down, the reading gradually went back down to the average. 

It is very sensitive, and this may lead people to think that it is faulty (like I first did!). However, if this is the case, there is probably something emitting VOCs in your house. 

One thing that I did notice was that the laser egg isn’t silent. Although it is very quiet, it is not totally quiet. At night, when there are no other sounds, I can occasionally hear the egg. 

This sound is by no means loud, and if there is any other sound at all you won’t hear it. However, in the total silence of night it is audible.

Connectivity 

Kaiterra Apple Homekit

The Laser Egg is very well connected! It integrates flawlessly with Apple Homekit.

As previously mentioned, one of the biggest appeals of the Laser Egg is the large range of connectivity that it offers. Although the egg does support IFTTT, I use an iPhone and a Mac, so I decided to opt for Apple Homekit instead.

If you haven’t used Homekit or IFTTT before, they are apps which allow IOT devices to connect to one another and automate functions. 

Within Homekit, the Laser Egg reports three stats – the air quality, humidity and temperature. This means that any of these readings can be used as a home automation tool. For example, I set my dehumidifier to automatically turn on (using a Homekit power socket) when the humidity reaches a high level.

The Laser egg connects using 2.4ghz WiFi, and this is my only issue with the connectivity. These days, many people use 5ghz WiFi, and if you use 5ghz WiFi, the egg won’t be recognised. This is a minor issue, but you may run into it if you have a modern router. 


Design

Laser Egg Review

The Laser Egg is simple and can fit in anywhere!

The Laser Egg follows a simple design language and this is something that I appreciate. The device itself looks like an egg that has been cut in half – with an LCD display on the flat face of the device.

The exterior is a solid white, with no disruptions. This means that it can fit in well with many desk or nightstand setups. At the rear of the device is a speaker-like grill and the USB charging port. 

The device easily fits in the palm of an adult hand. However, it definitely isn’t tiny. Although the exterior is plastic, it has a lot of weight due to the sensors inside. This means that the product doesn’t feel cheap.


Kaiterra App

Kaiterra Laser Egg App

To unlock the full functionality of the Laser Egg, you will need to download the Kaiterra App. This app allows you to access the settings of the egg as well as the graphs and more detailed data. 

The installation process is very straightforward. A QR code is presented on the egg, and once you scan this with your phone it will automatically connect. Once this brief process is complete, you can access the Laser Egg via your phone!

For the Laser Egg + Chemical, AQI, PM2.5, TVOC, temperature and humidity are all monitored and graphed. These graphs can then be viewed in minute, hour, and day formats. It’s a very simple and easy to understand layout that is very informative. 

If you are interested in doing further research, you can even export the data into a file which can be inspected in a graphing program such as Excel.
