Zigma Aerio-300 Smart Air Purifier Review

by Jones David

Indoor air pollution is caused by several sources such as heating, cooking, candles, wood burners, dry cleaning products, hairspray, etc. Most people associate air pollution with large factories or engines that emit smoke. But what they may not know is that air pollution can also occur in your own home. Due to the constant closures, people stay indoors more than ever, which means opening windows and taking walks (if you can) are essential.

Even without closures, being stuck at home is a reality for many people, such as office workers and seniors who cannot regularly open their windows due to mobility issues or live on a heavily polluted street. If you cannot get fresh air regularly, an air purifier like the Zigma Aerio 300 is a great alternative. The Zigma Aerio 300 meets all the requirements you could ask for in an air purifier, including eliminating odors, and you can even use it to dry clothes. The outer shell (including the base) is hard plastic with a smooth, matte finish. The edges and corners are rounded, and the unit has an automatic shut-off feature that turns off the motor and UVC unit when the front panel is removed, making it child-friendly.

The best thing we noticed during our tests is that the device is kid-friendly. The Zigma Smart WiFi air purifier has a child lock that prevents your children from operating the machine. We’ll also talk more about its features, performance, purification modes, and more as we go along.


The shape and size can be a deciding factor, especially if you live in a small flat or want to put an air purifier in a home office. The Zigma Aerio 300 Wi-Fi air purifier is nearly 420mm tall, with a large honeycomb grille on the front covering the filtration system that sits inside. The filtered air is then ventilated out through the top of the unit.

On top are three buttons – a small one on the left to turn on/off the night mode, the primary button in the middle that controls the power and different ways, and then another tiny button that turns on a UV-C light and an ionization mode. Surrounding the main switch is an LED light that indicates the air quality in the room. Blue and green mean suitable, but you know the air quality is unhealthy if you see orange or red.


The initial installation of the Smart Aerio 300 is effortless. The filter, which consists of several filters, must be inserted into the device. This requires removing the front grille and inserting the filter into the unit. Once that is done, you can start using the air purifier.

To fully use all the features, you need to download the free Zigma app for iOS or Android. There is a QR code on the back of the device that you need to scan, and it will walk you through the additional steps required to connect the Smart Aerio 300 to your WiFi (2.4Ghz only) and Google Nest or Alexa. You can automatically have the air cleaned manually or use the AI feature to automatically change the different modes.

There are three different manual fan speeds, the lowest of which is whisper quiet. However, the fan is very audible at level three, but it is rarely necessary to set it to the maximum in a standard room. However, if you use the fan in a kitchen where there are a lot of cooking odors, it may run at full speed when you are baking something, for example.

Filtration system

The activated carbon filter can remove the smell of pets, cat litter smell, kitchen smoke, smoke smell and neutralize formaldehyde and other toxic substances. The UV-C LED helps kill harmful viruses and bacteria, and in addition, the Aerio 300 creates negative ions to maintain the air clean.

Depending on the usage, the H14 filter may last between six and nine months, and it costs some amount to replace. You will get a notification in the app to notify you that it’s time to replace your old filter. You will get a percentage of the filter’s usage and how many days you have left before you change the filter from the app. When the filter expires, the air quality light ring will show red as a reminder.
